1.4 CE Compliance
Equipment is generally divided into two classes.
CLASS A
CLASS B
Digital equipment meant for light industrial use
Digital equipment meant for home use
Less restrictive emissions requirement:
less than 40 dB µV/m at 10 m
(40 dB relative to 1 µV/m) or 300 µV/m
More restrictive emissions requirement:
30 dB µV/m at 10 m or 100 µV/m
These limits apply over the range of 30–230 MHz. The limits are 7 dB higher for frequencies above 230 MHz. Although the test range goes to 1 GHz, the emissions from Rabbitbased systems at frequencies above 300 MHz are generally well below background noise
levels.
The BL2600 single-board computer has been tested and was found to
be in conformity with the following applicable immunity and emission
standards. The BL2610 single-board computer is also CE qualified as it
is a sub-version of the BL2600 single-board computer. Boards that are
CE-compliant have the CE mark.
NOTE: Earlier versions of the BL2600 that do not have the CE mark are not CE-compliant.
Immunity
The BL2600 series of single-board computers meets the following EN55024/1998 immunity standards.
• EN61000-4-3 (Radiated Immunity)
• EN61000-4-4 (EFT)
• EN61000-4-6 (Conducted Immunity)
Additional shielding or filtering may be required for a heavy industrial environment.
Emissions
The BL2600 series of single-board computers meets the following emission standards.
• EN55022:1998 Class B
• FCC Part 15 Class B
Your results may vary, depending on your application, so additional shielding or filtering
may be needed to maintain the Class B emission qualification.

SBC BL2600
1.4.1 Design Guidelines
Note the following requirements for incorporating the BL2600 series of single-board
computers into your application to comply with CE requirements.
General
• The power supply provided with the Tool Kit is for development purposes only. It is the
customer’s responsibility to provide a CE-compliant power supply for the end-product
application.
• When connecting the BL2600 single-board computer to outdoor cables, the customer is
responsible for providing CE-approved surge/lightning protection.
• Rabbit recommends placing digital I/O or analog cables that are 3 m or longer in a
metal conduit to assist in maintaining CE compliance and to conform to good cable
design practices.
• When installing or servicing the BL2600, it is the responsibility of the end-user to use
proper ESD precautions to prevent ESD damage to the BL2600.
Safety
• All inputs and outputs to and from the BL2600 series of single-board computers must
not be connected to voltages exceeding SELV levels (42.4 V AC peak, or 60 V DC).
• The lithium backup battery circuit on the BL2600 single-board computer has been
designed to protect the battery from hazardous conditions such as reverse charging and
excessive current flows. Do not disable the safety features of the design.
1.4.2 Interfacing the BL2600 to Other Devices
Since the BL2600 series of single-board computers is designed to be connected to other
devices, good EMC practices should be followed to ensure compliance. CE compliance is
ultimately the responsibility of the integrator. Additional information, tips, and technical
assistance are available from your authorized Rabbit distributor, and are also available on
our Web site at www.digi.com.

2.2 BL2600 Connections
1. Connect the programming cable to download programs from your PC and to program
and debug the BL2600.
NOTE: Use only the programming cable that has a blue shrink wrap around the RS-232
level converter (Part No. 101-0542). If you are using a BL2610, which is based on the
RCM3100, you will need the programming cable that has a red shrink wrap around the
RS-232 level converter (Part No. 101-0513). Other programming cables are not be
voltage-compatible or their connector sizes may be different.
Connect the 10-pin PROG connector of the programming cable to header J3 on the
BL2600’s RabbitCore module (the programming header is labeled J1 on special-edition
BL2600s based on the RCM3365/RCM3375). Ensure that the colored edge lines up with
pin 1 as shown. (Do not use the DIAG connector, which is used for monitoring only.) Connect the other end of the programming cable to a COM port on your PC. Make a note of
the port to which you connect the cable, as Dynamic C will need to have this parameter
configured. Note that COM1 on the PC is the default COM port used by Dynamic C.

SBC BL2600
2. When all other connections have been made, you can connect power to the BL2600.
First, prepare the AC adapter for the country where it will be used by selecting the plug.
The BL2600 Tool Kit presently includes Canada/Japan/U.S., Australia/N.Z., U.K., and
European style plugs. Snap in the top of the plug assembly into the slot at the top of the
AC adapter as shown in Figure 4, then press down on the spring-loaded clip below the
plug assembly to allow the plug assembly to click into place.
Connect the AC apapter to header J12 on the BL2600 as shown in Figure 4. You can
use the crimps and the friction-lock connector included in the Tool Kit to connect the
leads from the power supply, then match the friction lock tab on the friction-lock connector to the back of header J12 on the BL2600 as shown. The friction-lock connector
will only fit one way.
Figure 4. Power Supply Connections
3. Apply power.
Plug in the AC adapter. The power LED will light up when the BL2600 is powered up
correctly.
CAUTION: Unplug the AC adapter while you make or otherwise work with the connections
to the headers. This will protect your BL2600 from inadvertent shorts or power spikes.
2.2.1 Hardware Reset
A hardware reset is done by unplugging the ACV adapter, then plugging it back in, or by
pressing the RESET button located just above the RabbitCore module.

2.3 Installing Dynamic C
If you have not yet installed Dynamic C version 8.51 (or a later version), do so now by
inserting the Dynamic C CD from the BL2600 Tool Kit in your PC’s CD-ROM drive. The
CD will auto-install unless you have disabled auto-install on your PC.
If the CD does not auto-install, click Start > Run from the Windows Start button and
browse for the Dynamic C setup.exe file on your CD drive. Click OK to begin the
installation once you have selected the setup.exe file.
The online documentation is installed along with Dynamic C, and an icon for the documentation menu is placed on the workstation’s desktop. Double-click this icon to reach the
menu. If the icon is missing, create a new desktop icon that points to default.htm in the
docs folder, found in the Dynamic C installation folder.
The latest versions of all documents are always available for free, unregistered download
from our Web sites as well.
The Dynamic C User’s Manual provides detailed instructions for the installation of
Dynamic C and any future upgrades.
NOTE: If you have an earlier version of Dynamic C already installed, the default installation of the later version will be in a different folder, and a separate icon will appear on
your desktop.
Once your installation is complete, you will have up to three icons on your PC desktop.
One icon is for Dynamic C, one opens the documentation menu, and the third is for the
Rabbit Field Utility, a tool used to download precompiled software to a target system.
If you have purchased any of the optional Dynamic C modules, install them after installing
Dynamic C. The modules may be installed in any order. You must install the modules in
the same directory where Dynamic C was installed.
12
SBC BL2600
2.4 Starting Dynamic C
Once the BL2600 is connected to your PC and to a power source, start Dynamic C by
double-clicking on the Dynamic C icon on your desktop or in your Start menu.
If you are using a USB port to connect your computer to the BL2600, choose Options >
Project Options and check “Use USB to Serial Converter” in “Serial Options” on the
Communications tab. Click OK to save the settings.
If you are using a BL2600 model running at 44.2 MHz, set the compiler to run the application in the fast program execution SRAM by selecting “Code and BIOS in Flash, Run in
RAM” in the “BIOS Memory Setting” on the Compiler tab under the Options > Project
Options menu. Click OK to save the settings.
Dynamic C defaults to using the serial port on your PC that you specified during installation. If the port setting is correct, Dynamic C should detect the BL2600 and go through a
sequence of steps to cold-boot the BL2600 and to compile the BIOS. (Some versions of
Dynamic C will not do the initial BIOS compile and load until the first time you compile a
program.)
If you receive the message No Rabbit Processor Detected, the programming
cable may be connected to the wrong COM port, a connection may be faulty, or the target
system may not be powered up. First, check both ends of the programming cable to ensure
that it is firmly plugged into the PC and the programming port.
If there are no faults with the hardware, select a different COM port within Dynamic C.
On your computer, open Control Panel > System > Hardware > Device Manager >
Ports and look at the list of available COM ports. In Dynamic C, select Options > Project Options, then select one of these available COM ports on the Communications tab,
then click OK. Press <Ctrl-Y> to force Dynamic C to recompile the BIOS. If Dynamic C still
reports it is unable to locate the target system, repeat the above steps for another available
COM port. You should receive a Bios compiled successfully message once this
step is completed successfully.
If Dynamic C appears to compile the BIOS successfully, but you then receive a communication error message when you compile and load a sample program, it is possible that your
PC cannot handle the higher program-loading baud rate. Try changing the maximum
download rate to a slower baud rate as follows.
• Locate the Serial Options dialog in the Dynamic C Options > Communications
menu. Select a slower Max download baud rate. Click OK to save the settings.
If a program compiles and loads, but then loses target communication before you can
begin debugging, it is possible that your PC cannot handle the default debugging baud
rate. Try lowering the debugging baud rate as follows.
• Locate the Serial Options dialog in the Dynamic C Options > Communications
menu. Choose a lower debug baud rate. Click OK to save the settings.

2.5 PONG.C
You are now ready to test your set-up by running a sample program.
Find the file PONG.C, which is in the Dynamic C SAMPLES folder. To run the program,
open it with the File menu (if it is not still open), compile it using the Compile menu, and
then run it by selecting Run in the Run menu. The STDIO window will open and will display a small square bouncing around in a box.
This program shows that the CPU is working. The sample program described in
Section 5.2.3, “Run the PINGME.C Demo,” tests the TCP/IP portion of the board.
2.6 Where Do I Go From Here?
NOTE: If you purchased your BL2600 through a distributor or Rabbit partner, contact
the distributor or partner first for technical support.
If there are any problems at this point:
• Use the Dynamic C Help menu to get further assistance with Dynamic C.
• Check the Rabbit Technical Bulletin Board and forums at www.rabbit.com/support/bb/
and at www.rabbit.com/forums/.
• Use the Technical Support e-mail form at www.rabbit.com/support/questionSubmit.shtml.
If the sample program ran fine, you are now ready to go on to explore other BL2600 features and develop your own applications.
Chapter 3, “Subsystems,” provides a description of the BL2600’s features, Chapter 4,
“Software,” describes the Dynamic C software libraries and introduces some sample programs, and Chapter 5, “Using the TCP/IP Features,” explains the TCP/IP features.

3.1.1 Connector Options
Standard BL2600 models are equipped with two 1 × 20 friction-lock connector terminals
(J1 and J2), two polarized 1 × 10 friction-lock connector terminals (J8 and J15) where pin 9
is removed to polarize the connector terminals, one 1 × 13 friction-lock connector terminal
(J16), and one 1 × 10 friction-lock connector terminal (J17); all of these friction-lock connector terminals have a 0.1" pitch.
Two 4-pin 0.156" friction-lock connector terminals at J5 and J7 are installed to supply
power (DCIN and +5 V) to the RabbitNet peripheral expansion boards. The 4-pin 0.156"
friction-lock connector terminal at J12 is for the main power supply connections.
Table 3 lists Molex connector part numbers for the crimp terminals, housings, and polarizing
keys needed to assemble female friction-lock connector assemblies for use with their male
counterparts on the BL2600.

3.2.2 PWM Outputs
Digital inputs DIN20–DIN23 can be used as PWM output channels by setting the jumper
on header JP4 across pins 7–8 to pull the digital inputs to ground. Once the PWM driver
sets up a given PWM channel, the corresponding digital input channel is no longer available for use as a digital input. The output voltage swing will be 0 to 1.65 V, which is not
suitable for interfacing only to CMOS-level inputs. Since the output impedance is approximately 13 k, the input impedance of the circuit the PWM output is connected to should
be at least 10 times as high.
The sample program PWM.C in the IO subdirectory in SAMPLES\BL2600 shows how to
set up and use the PWM outputs.

3.2.3 High-Current Digital Outputs
The BL2600 has four high-current digital outputs, HOUT0–HOUT3, which can each sink
or source up to 2 A. Figure 9 shows a wiring diagram for using the digital outputs in either
a sinking or a souring configuration.

Figure 9. BL2600 High-Current Digital Outputs
All the digital outputs sink and source actively. They can be used as high-side drivers, lowside drivers, or as an H-bridge driver. When the BL2600 is first powered up or reset, all
the outputs are disabled, that is, at a high-impedance tristate, until the digHoutConfig
software function call is made. The digHoutConfig call sets the initial state of each
high-current output according to the configuration specified by the user, and enables the
digital outputs to their initial status.

CAUTION: If you are using a BL2600 with the IDC header connectors, beware that

outputs are available on opposite pairs of IDC header connectors, you can still use the
2 A sinking or sourcing capability of the BL2600 by wiring all your connections,
including the ground, in parallel to the opposite pairs (see Figure 10 for an example).

3.2.4 Configurable I/O
The BL2600 has 16 configurable I/O that may be configured individually in software as
either digital inputs or as sinking digital outputs. By default, a configurable I/O channel is
a digital input, but may be set as a sinking digital output by using the digOutConfig
function call. The inputs are factory-configured to be pulled up to +5 V, but they can also
be pulled up to +K or DCIN, or pulled down to 0 V in banks by changing a jumper as
shown in Figure 12.
CAUTION: Do not simultaneously jumper more than one setting on a particular
jumper header (JP1 and JP2) when configuring a bank of configrable I/O.

As for the nonconfigurable digital inputs, the actual switching threshold is approximately
1.40 V. Anything below this value is a logic 0, and anything above is a logic 1. The digital
inputs are each fully protected over a range of -36 V to +36 V, and can handle short spikes
of ±40 V.
NOTE: If the inputs are pulled up to +K or to DCIN, the voltage range over which
the digital inputs are protected changes to +K (or DCIN) – 36 V to +36 V.
When set as a sinking digital output, a configurable I/O channel can sink up to 200 mA at
up to 40 V. When you use the software digOutConfig function call to set the configurable I/O, DIO00–DIO15 are considered to be digital output channels 00–15. The output
can be set up either as a sinking output or it can be put in a high-impedance tristate.
When a configurable I/O is configured
as a sinking output, be sure to connect
an external voltage source up to 36 V
DC across +K and GND on header
J1/J3, and set the pullup jumper on the
corresponding JP1/JP2 header to +K.

3.3 Serial Communication
The BL2600 has three serial communication ports, which can be configured as one RS-232
serial channel (with RTS/CTS) and one RS-232 (3-wire) channel or one RS-485 channel, or
as three RS-232 (3-wire) channels, or as two RS-232 (3-wire) channels and one RS-485
channel by using the serMode software function call. Table 8 summarizes the options.

The BL2600 also has one CMOS serial channel that serves as the programming port.
All four serial ports operate in an asynchronous mode. An asynchronous port can handle 7
or 8 data bits. A 9th bit address scheme, where an additional bit is sent to mark the first
byte of a message, is also supported. Serial Port A, the programming port, can be operated
alternately in the clocked serial mode. In this mode, a clock line synchronously clocks the
data in or out. Either of the two communicating devices can supply the clock. The BL2600
boards typically use all four ports in the asynchronous serial mode. Serial Ports C and F
are used for RS-232 communication, and Serial Port E is used for RS-232 or RS-485 communication. The BL2600 uses a 22.12 MHz resonator, which is doubled to 44.2 MHz. At
this frequency, the BL2600 supports standard asynchronous baud rates up to a maximum
of 5.525 Mbps.
3.3.1 RS-232
The BL2600 RS-232 serial communication is supported by an RS-232 transceiver. This
transceiver provides the voltage output, slew rate, and input voltage immunity required to
meet the RS-232 serial communication protocol. Basically, the chip translates the Rabbit
3000’s CMOS signals to RS-232 signal levels. Note that the polarity is reversed in an
RS-232 circuit so that a +3.3 V output becomes approximately -10 V and 0 V is output as
+10 V. The RS-232 transceiver also provides the proper line loading for reliable communication.
RS-232 can be used effectively at the BL2600’s maximum baud rate for distances of up to
15 m.
3.3.2 RS-485
The BL2600 can be set for one RS-485 serial channel, which is connected to the Rabbit
3000 Serial Port E through an RS-485 transceiver. The half-duplex communication uses
the Rabbit 3000’s PE3 pin to control the transmit enable on the communication line.

SBC BL2600
For best performance, the bias and termination resistors in a multidrop network should
only be enabled on both end nodes of the network. Disable the termination and bias resistors on any intervening BL2600 units in the network by removing both jumpers from
header JP6.
TIP: Save the jumpers for possible future use by “parking” them across pins 1–3 and 4–6
of header JP7. Pins 3 and 4 are not otherwise connected to the BL2600.
3.3.3 Programming Port
The RabbitCore module on the BL2600 has a 10-pin programming header. The programming port uses the Rabbit 3000’s Serial Port A for communication, and is used for the following operations.
• Programming/debugging
• Cloning
The programming port is used to start the BL2600 in a mode where the BL2600 will
download a program from the port and then execute the program. The programming port
transmits information to and from a PC while a program is being debugged.
The Rabbit 3000 startup-mode pins (SMODE0, SMODE1) are presented to the programming port so that an externally connected device can force the BL2600 to start up in an
external bootstrap mode. The BL2600 can be reset from the programming port via the
/EXT_RSTIN line.
The Rabbit 3000 status pin is also presented to the programming port. The status pin is an
output that can be used to send a general digital signal.
NOTE: Refer to the Rabbit 3000 Microprocessor User’s Manual for more information
related to the bootstrap mode.

3.3.4 Ethernet Port
Figure 16 shows the pinout for the Ethernet port (J4 on the BL2600 module). Note that
there are two standards for numbering the pins on this connector—the convention used
here, and numbering in reverse to that shown. Regardless of the numbering convention
followed, the pin positions relative to the spring tab position (located at the bottom of the
RJ-45 jack in Figure 16) are always absolute, and the RJ-45 connector will work properly
with off-the-shelf Ethernet cables.

3.4 A/D Converter Inputs
The single A/D converter chip used in the BL2600 has a resolution of 12 bits (11 bits for the
value and one bit for the polarity). The A/D converter chip has a programmable amplifier.
Each external input has circuitry that provides scaling and filtering. All 8 external inputs
are scaled and filtered to provide the user with an input impedance of 1 M and a variety
of single-ended unipolar, single-ended bipolar, and differential bipolar ranges as shown in
Table 9.
Figure 17 shows a pair of A/D converter input circuits. The resistors form an approx. 10:1
attenuator, and the capacitors filter noise pulses from the A/D converter inputs.

The A/D converter inputs are factory-calibrated and the calibration constants are stored in a
separate EEPROM.
3.4.1 A/D Converter Calibration
To get the best results form the A/D converter, it is necessary to calibrate each mode (single-ended, differential, and current) for each of its gains. It is imperative that you calibrate
each of the A/D converter inputs in the same manner as they are to be used in the application. For example, if you will be performing floating differential measurements or differential measurements using a common analog ground, then calibrate the A/D converter in
the corresponding manner. The calibration table in software only holds calibration constants based on mode, channel, and gain. Other factors affecting the calibration must be taken
into account by calibrating using the same mode and gain setup as in the intended use.
Sample programs are provided to illustrate how to read and calibrate the various A/D
inputs for the three operating modes.

3.5 D/A Converter Outputs
The four D/A converter outputs are buffered and scaled to provide an output from 0 V to
+10 V (12-bit resolution) or ±10 V (11-bit resolution, one bit used for polarity). There are
also four 4–20 mA current outputs. Figure 18 shows the D/A converter outputs.

Figure 18. D/A Converter Outputs
To stay within the maximum power dissipation of the D/A converter circuit, the maximum
D/A converter output current is 10 mA per channel for the voltage outputs. If you are
using the current outputs, keep the resistance driven by a current output channel below
400  to stay within the voltage compliance capability of the op-amp output circuit.
As Figure 18 shows, both the voltage and the current outputs for a particular channel are
driven by the same output on the D/A converter chip. As a result, either the anaOutVolts
or the anaOutmAmps function calls will set both the voltage and the current outputs corresponding to a particular channel. For example, if anaOutVolts sets unipolar channel
AV0 to be +10 V, AI0 will be 20 mA; if anaOutVolts sets unipolar channel AV0 to be
+5 V, AI0 will be 12 mA, the midpoint of the 4–20 mA range. It is possible to connect a
load to both the corresponding voltage and current outputs as long as the combined current
consumption does not exceed the 20 mA individual limit.
Because of the “connection” between the analog voltage outputs and the analog current
outputs, the configuration of the analog voltage outputs with the anaOutConfig function
call as unipolar outputs with 12-bit resolution or as bipolar outputs with 11-bit resolution
User’s Manual
31
also affects the resolution of the 4–20 mA current outputs—you need to configure a voltage output for unipolar operation if you want 12-bit resolution on the associated current
output.
There are other effects on a current output when the associated voltage output is operating
in the bipolar mode. While voltages of 0 to +10 V still correspond to currents of 4 to 20 mA,
the current cannot be determined reliably for voltages below 0 V, and will be “negative” at
voltages below -2.5 V. Thus the current output effectively becomes a “current sink”
instead of a “current source.”
The D/A converter outputs are factory-calibrated and the calibration constants are stored in a
separate EEPROM.
3.5.1 D/A Converter Calibration
To get the best results form the D/A converter, it is necessary to calibrate each mode (unipolar, bipolar, and current) for each of its gains. It is imperative that you calibrate each of
the D/A converter outputs in the same manner as they are to be used in the application.
The calibration table in software only holds calibration constants based on unipolar, bipolar, and voltage or current operation. Other factors affecting the calibration must be taken into
account by calibrating using the same mode and voltage/current setup as in the intended use.
Sample programs are provided to illustrate how to calibrate the various D/A outputs for
the three operating modes.

Figure 19. Analog Reference Voltages
The A/D converter chip supplies the 2.048 V reference voltage, which is divided in half
and then amplified and buffered to provide the 1.667 V and 2.5 V reference voltages used
by the digital output circuits.
The D/A converter chip provides the reference voltages for the digital inputs to provide
single-ended unipolar or differential measurements [0 V], or to provide single-ended
bipolar measurements [V = (voltage range) ÷ 9]. Because the D/A converter chip operation
is configured by the anaOutConfig function, it is important to run the anaOutConfig
function before running anaInConfig if you plan to use the digital outputs to ensure that
the reference voltages are established first before the analog inputs are configured.

3.7 Serial Programming Cable
The programming cable is used to connect the serial programming port of the BL2600 to a
PC serial COM port. The programming cable converts the RS-232 voltage levels used by
the PC serial port to the CMOS voltage levels used by the Rabbit 3000.
When the PROG connector on the programming cable is connected to the programming
header on the BL2600’s RabbitCore module, programs can be downloaded and debugged
over the serial interface.
The DIAG connector of the programming cable may be used on the programming header on
the BL2600’s RabbitCore module with the BL2600 operating in the Run Mode. This
allows the programming port to be used as a regular serial port.
3.7.1 Changing Between Program Mode and Run Mode
The BL2600 is automatically in Program Mode when the PROG connector on the programming cable is attached, and is automatically in Run Mode when no programming
cable is attached. When the Rabbit 3000 is reset, the operating mode is determined by the
status of the SMODE pins. When the programming cable’s PROG connector is attached,
the SMODE pins are pulled high, placing the Rabbit 3000 in the Program Mode. When the
programming cable’s PROG connector is not attached, the SMODE pins are pulled low,
causing the Rabbit 3000 to operate in the Run Mode.

SBC BL2600
3.8 Other Hardware
3.8.1 Clock Doubler
The BL2600 takes advantage of the Rabbit 3000 microprocessor’s internal clock doubler.
A built-in clock doubler allows half-frequency crystals to be used to reduce radiated emissions. The 44.2 MHz frequency specified for the BL2600 is generated using a 22.12 MHz
resonator, and the 29.4 MHz frequency specified for the BL2610 is generated using a
14.7456 MHz crystal.
The clock doubler may be disabled if the higher clock speeds are not required. Disabling
the Rabbit 3000 microprocessor’s internal clock doubler will reduce power consumption
and further reduce radiated emissions. The clock doubler is disabled with a simple configuration macro as shown below.
1. Select the “Defines” tab from the Dynamic C Options > Project Options menu.
2. Add the line CLOCK_DOUBLED=0 to always disable the clock doubler.
The clock doubler is enabled by default, and usually no entry is needed. If you need to
specify that the clock doubler is always enabled, add the line CLOCK_DOUBLED=1 to
always enable the clock doubler.
3. Click OK to save the macro. The clock doubler will now remain off whenever you are
in the project file where you defined the macro.
3.8.2 Spectrum Spreader
The Rabbit 3000 features a spectrum spreader, which helps to mitigate EMI problems. By
default, the spectrum spreader is on automatically, but it may also be turned off or set to a
stronger setting. The means for doing so is through a simple configuration macro as shown
below.
1. Select the “Defines” tab from the Dynamic C Options > Project Options menu.
2. Normal spreading is the default, and usually no entry is needed. If you need to specify normal spreading, add the line
ENABLE_SPREADER=1
For strong spreading, add the line
ENABLE_SPREADER=2
To disable the spectrum spreader, add the line
ENABLE_SPREADER=0
NOTE: The strong spectrum-spreading setting is not recommended since it may limit
the maximum clock speed or the maximum baud rate. It is unlikely that the strong setting will be used in a real application.
3. Click OK to save the macro. The spectrum spreader will now remain off whenever you are
in the project file where you defined the macro.
NOTE: Refer to the Rabbit 3000 Microprocessor User’s Manual for more information
on the spectrum-spreading setting and the maximum clock speed.

3.9 Memory
3.9.1 SRAM
The BL2600 modules running at clock speeds of 44.2 MHz have 512K of programexecution SRAM. All the BL2600 modules have 256K–512K of data SRAM.
3.9.2 Flash Memory
The BL2600 also has 512K of flash memory.
NOTE: Rabbit recommends that any customer applications should not be constrained by
the sector size of the flash memory since it may be necessary to change the sector size
in the future.
Writing to arbitrary flash memory addresses at run time is also discouraged. Instead,
define a “user block” area to store persistent data. The functions writeUserBlock and
readUserBlock are provided for this.
A Flash Memory Bank Select jumper configuration option based on 0  surface-mounted
resistors exists at location JP4 on the RabbitCore module (BL2600) or at location JP1 on
the RabbitCore module (BL2610). These options are reserved for future use.
3.9.3 Serial Flash
Socket J9 is provided to allow you to plug in an optional Rabbit SF1000 serial flash via
Serial Port D. You may use two 0.375" (9.5 mm) spacers with 4-40 × 3/4 screws and nuts
to attach the SF1000 securely.

SBC BL2600
3.9.4 NAND Flash
The RCM3365 and the RCM3375 RabbitCore modules used with the additional BL2600
versions described in Section 1.2.2 support a removable memory card to store data and
Web pages. The RCM3365 and the RCM3375 both can handle up to a 128 MByte removable memory card, and the RCM3365 also has a 16 MByte onboard NAND flash.
NOTE: Rabbit-based systems do not implement the xD-Picture Card™ specification for
data storage, and are neither compatible nor compliant with xD-Picture Card™ card
readers.
The NAND flash and removable memory cards are particularly suitable for mass-storage
applications, but are generally unsuitable for direct program execution. The NAND flash
differs from parallel NOR flash (the type of flash memory used to store program code on
Rabbit-based boards and RabbitCore modules currently in production) in two respects.
First, the NAND flash requires error-correcting code (ECC) for reliability. Although
NAND flash manufacturers do guarantee that block 0 will be error-free, most manufacturers guarantee that a new NAND flash chip will be shipped with a relatively small percentage of errors, and will not develop more than some maximum number or percentage of
errors over its rated lifetime of up to 100,000 writes. Second, the standard NAND flash
addressing method multiplexes commands, data, and addresses on the same I/O pins,
while requiring that certain control lines must be held stable for the duration of the NAND
flash access. The software function calls provided by Rabbit for the NAND flash take care
of the data-integrity and reliability attributes.
Figure 22 shows how to insert or remove the memory card. While you remove or insert
the memory card, take care to avoid touching the electrical contacts on the bottom of the
card to prevent electrostatic discharge damage to the card and to keep any moisture and
contaminants off the contacts. Do not remove or insert the memory card while it is being
accessed.

Figure 22. Insertion/Removal of Memory Card
User’s Manual
37
Rabbit recommends that you use header J6 on the RCM3365/RCM3375 only for the
memory card since other devices are not supported. Be careful to remove and insert the
memory card as shown, and be careful not to insert any foreign objects, which may short
out the contacts and lead to the destruction of your memory card.
Sample programs in the SAMPLES\BL2600\NANDFlash folder illustrate the use of the
NAND flash. These sample programs are described in Section 4.2.7, “Use of NAND
Flash.” Pay careful attention to the sample programs to see how to close files and secure
any data on the memory card before you remove it.

SBC BL2600
4. SOFTWARE
Dynamic C is an integrated development system for writing
embedded software. It runs on an IBM-compatible PC and is
designed for use with single-board computers and other devices
based on the Rabbit microprocessor.
Chapter 4 provides the libraries, function calls, and sample programs related to the BL2600.
4.1 Running Dynamic C
You have a choice of doing your software development in the flash memory or in the
static RAM included on the BL2600. The flash memory and SRAM options are selected
with the Options > Project Options > Compiler menu.
The advantage of working in RAM is to save wear on the flash memory, which is limited
to about 100,000 write cycles. The disadvantage is that the code and data might not both
fit in RAM.
NOTE: On the BL2600, compiling a program to flash will produce a warning message.
You will receive an error message if you attempt to compile a program to the batterybacked data SRAM. If you still want to compile to the battery-backed data SRAM, you
will have to comment out some code as instructed in the error message. The program
should be run from the program execution SRAM after the programming cable is disconnected. Your final code must always be stored in flash memory for reliable operation. Select Code and BIOS in Flash, Run in RAM from the Dynamic C Options >
Project Options > Compiler menu to store the code in flash and copy it to the fast
program execution SRAM at run-time to take advantage of the faster clock speed. This
option optimizes the performance of the BL2600 with an RCM3200 RabbitCore module
running at 44.2 MHz.
NOTE: On the BL2610, an application can be developed in RAM, but cannot run standalone from RAM after the programming cable is disconnected. Standalone applications
can only run from flash memory.
NOTE: Do not depend on the flash memory sector size or type. Due to the volatility of
the flash memory market, the BL2600 and Dynamic C were designed to accommodate
flash devices with various sector sizes.
User’s Manual
39
Developing software with Dynamic C is simple. Users can write, compile, and test C and
assembly code without leaving the Dynamic C development environment. Debugging
occurs while the application runs on the target. Alternatively, users can compile a program
to an image file for later loading. Dynamic C runs on PCs under Windows 95, 98, 2000,
NT, Me, and XP. Programs can be downloaded at baud rates of up to 460,800 bps after the
program compiles.
Dynamic C has a number of standard features:
• Full-feature source and/or assembly-level debugger, no in-circuit emulator required.
• Royalty-free TCP/IP stack with source code and most common protocols.
• Hundreds of functions in source-code libraries and sample programs:
 Exceptionally fast support for floating-point arithmetic and transcendental functions.
 RS-232 and RS-485 serial communication.
 Analog and digital I/O drivers.
 I2C, SPI, GPS, file system.
 LCD display and keypad drivers.
• Powerful language extensions for cooperative or preemptive multitasking
• Loader utility program to load binary images into Rabbit targets in the absence of
Dynamic C.
• Provision for customers to create their own source code libraries and augment on-line
help by creating “function description” block comments using a special format for
library functions.
• Standard debugging features:
 Breakpoints—Set breakpoints that can disable interrupts.
 Single-stepping—Step into or over functions at a source or machine code level, µC/OS-II aware.
 Code disassembly—The disassembly window displays addresses, opcodes, mnemonics, and
machine cycle times. Switch between debugging at machine-code level and source-code level by
simply opening or closing the disassembly window.
 Watch expressions—Watch expressions are compiled when defined, so complex expressions
including function calls may be placed into watch expressions. Watch expressions can be updated
with or without stopping program execution.
 Register window—All processor registers and flags are displayed. The contents of general registers
may be modified in the window by the user.
 Stack window—shows the contents of the top of the stack.
 Hex memory dump—displays the contents of memory at any address.
 STDIO window—printf outputs to this window and keyboard input on the host PC can be
detected for debugging purposes. printf output may also be sent to a serial port or file.

4.1.1 Upgrading Dynamic C
4.1.1.1 Patches and Updates
Dynamic C patches that focus on bug fixes and updates are available from time to time.
Check the Web site at www.rabbit.com/support/ for the latest patches, workarounds, and
updates.
The default installation of a patch or update is to install the file in a directory (folder)
different from that of the original Dynamic C installation. Rabbit recommends using a different directory so that you can verify the operation of the patch or update without overwriting the existing Dynamic C installation. If you have made any changes to the BIOS or
to libraries, or if you have programs in the old directory (folder), make these same changes
to the BIOS or libraries in the new directory containing the patch. Do not simply copy
over an entire file since you may overwrite an update; of course, you may copy over any
programs you have written. Once you are sure the new patch or update works entirely to
your satisfaction, you may retire the existing installation, but keep it available to handle
legacy applications.
4.1.1.2 Upgrades
Dynamic C installations are designed for use with the board they are included with, and
are included at no charge as part of our low-cost kits. Dynamic C is a complete software
development system, but does not include all the Dynamic C features. Rabbit also offers
for sale add-on Dynamic C modules containing the popular µC/OS-II real-time operating
system, as well as PPP, Advanced Encryption Standard (AES), RabbitWeb, FAT File
System, Secure Socket Layer (SSL) and other select libraries. In addition to the Webbased technical support included at no extra charge, a one-year telephone-based technical
support module is also available for purchase.

4.2 Sample Programs
Sample programs are provided in the Dynamic C Samples folder. The sample program
PONG.C demonstrates the output to the STDIO window.
The various directories in the Samples folder contain specific sample programs that illustrate the use of the corresponding Dynamic C libraries.
The BL2600 folder provides sample programs specific to the BL2600. Each sample program has comments that describe the purpose and function of the program. Follow the
instructions at the beginning of the sample program.
To run a sample program, open it with the File menu (if it is not still open), then compile
and run it by pressing F9. The BL2600 must be in Program mode (see Section 3.7, “Serial
Programming Cable,”) and must be connected to a PC using the programming cable as
described in Section 2.2, “BL2600 Connections.”
More complete information on Dynamic C is provided in the Dynamic C User’s Manual.
TCP/IP specific functions are described in the Dynamic C TCP/IP User’s Manual. Information on using the TCP/IP features and sample programs is provided in Section 5,
“Using the TCP/IP Features.”
4.2.1 General BL2600 Sample Programs
The following sample programs are found in the SAMPLES\BL2600 folder.
• BOARD_ID.C—This program is used to identify the model of BL2600 being used, and
displays that information in the STDIO window.
4.2.2 Digital I/O
The following sample programs are found in the IO subdirectory in SAMPLES\BL2600.
• DIGIN.C—Demonstrates the use of the digital inputs. Using the Demonstration Board,
you can see an input channel toggle from HIGH to LOW when pressing a pushbutton
on the Demonstration Board. See Appendix C for hookup instructions for the Demonstration Board. This sample program does not explicitly configure any of the configurable I/O, so all the configurable I/O are available by default as digital inputs.
• DIGIN_BANK.C—Demonstrates the use of digInBank to read digital inputs. Using the
Demonstration Board, you can see an input channel toggle from HIGH to LOW when
pressing a pushbutton on the Demonstration Board. See Appendix C for hookup
instructions for the Demonstration Board. This sample program does not explicitly configure any of the configurable I/O, so all the configurable I/O are available by default as
digital inputs.
• DIGOUT.C—Demonstrates the use of the configurable I/O sinking outputs. Using the
Demonstration Board, you can see an LED toggle on/off via a sinking output. See
Appendix C for hookup instructions for the Demonstration Board.
• DIGOUT_BANK.C—Demonstrates the use of digInBank to control the configurable I/O
sinking outputs. Using the Demonstration Board, you can see an LED toggle on/off via
a sinking output. See Appendix C for hookup instructions for the Demonstration Board.
42
SBC BL2600
• HIGH_CURRENT_IO.C—Demonstrates the use of the high-current outputs configured
as either sinking or sourcing outputs. High-current output HOUT0 is configured for
sourcing to provide power to the Demonstration Board. Outputs HOUT1 and HOUT2
are configured to demonstrate tristate operation to toggle the LEDs on the Demonstration Board. Output HOUT3 is configured as a sinking output to toggle an LED on the
Demonstration Board. See Appendix C for hookup instructions for the Demonstration
Board.
• PWM.C—Demonstrates the use of the four PWM channels on Parallel Port F (PF4–PF7)
on pins DIN20–DIN23. The PWM signals are set for a frequency of 10 kHz with the
duty cycle adjustable from 1 to 99% by the user. Follow these instructions when running this sample program.
1. Connect the jumper across pins 7–8 on header JP4 to select the GND option.
2. Once you have compiled and run this program, you may change duty cycle for a given PWM channel via the Dynamic C STDIO window and use either an oscilloscope or a voltmeter to view the
output. When monitoring with a voltmeter, you can compute the expected voltage
Vout = PWM percentage × 1.65 V
since the output voltage swing is from 0 V to 1.65 V DC.
4.2.3 Serial Communication
The following sample programs are found in the RS232 subdirectory in SAMPLES\BL2600.
• PARITY.C—This sample program repeatedly sends byte values 0–127 from Serial Port F
to Serial Port C. The program switches between generating parity and not generating
parity on Serial Port F. Serial Port C will always be checking parity, so parity errors
should occur during every other sequence. The results are displayed in the Dynamic C
STDIO window.
Connect TxF to RxC before compiling and running this sample program.
NOTE: For the sequence that does yield parity errors, the errors won't occur for each
byte received. This is because certain byte patterns along with the stop bit will appear to
generate the correct parity for the UART.
• SIMPLE3WIRE.C—This program demonstrates basic RS-232 serial communication.
Connect TxC to RxF on header J17 and connect TxF to RxC on header J17 before compiling and running this sample program.
• SIMPLE5WIRE.C—This program demonstrates 5-wire RS-232 serial communication.
Connect TxC to RxC on header J17 and connect TxF to RxF on header J17 before compiling and running this sample program.
TxF and RxF become the flow control RTS and CTS. To test flow control, disconnect
RTS from CTS while running this program. Characters should stop printing in the
Dynamic C STDIO window and should resume when RTS and CTS are connected again
User’s Manual
43
The following sample programs are found in the RS485 subdirectory in SAMPLES\BL2600.
• MASTER.C—This program demonstrates a simple RS-485 transmission of lower case
letters to a slave. The slave will send back converted upper case letters back to the
master BL2600 and display them in the STDIO window. Use SLAVE.C to program the
slave. Make the following connections between the master and slave:
485+ to 485+
485- to 485GND to GND
• SLAVE.C—This program demonstrates a simple RS-485 transmission of lower case
letters to a slave. The slave will send back converted upper case letters back to the

option to either inspect or clear a page of serial flash memory.
• SFLASH_TEST.C—Demonstrates how to read and write data from/to the SF1000.
Once the sample program is compiled and run, it displays a message in the Dynamic C
STDIO window to report whether the test was successful.
4.2.7 Use of NAND Flash
The following sample programs can be found in the SAMPLES\BL2600\NANDFlash folder.
• NFLASH_DUMP.C—This program is a utility for dumping the nonerased contents of a
NAND flash chip to the Dynamic C STDIO window, and the contents may be redirected to a serial port.
When the sample program starts running, it attempts to initialize the user-selected
NAND flash chip. If the initialization is successful and the main page size is acceptable, the nonerased page contents (non 0xFF) from the NAND flash page are dumped
to the Dynamic C STDIO win.for inspection.
Note that an error message will appear when the first 32 pages (0x20 pages) are
“dumped.” You may ignore the error message.
• NFLASH_INSPECT.C—This program is a utility for inspecting the contents of a
NAND flash chip. When the sample program starts running, it attempts to initialize the
NAND flash chip selected by the user. Once a NAND flash chip is found, the user can
execute various commands to print out the contents of a specified page, clear (set to
zero) all the bytes in a specified page, erase, or write to specified pages.
CAUTION: When you run this sample program, enabling the #define
NFLASH_CANERASEBADBLOCKS macro makes it possible to write to bad blocks. The
first two blocks on the memory card are marked bad to protect the configuration data
needed to use the card in a digital camera or PC. You will only be able to use the memory card in Rabbit-based systems if either of the first two blocks is written to.
• NFLASH_LOG.C—This program runs a simple Web server and stores a log of hits in
the NAND flash. This log can be viewed and cleared from a browser.
46
SBC BL2600
• NFLASH_ERASE.C—This program is a utility to erase all the good blocks on a NAND
flash chip. When the program starts running, it attempts to initialize the NAND flash
chip selected by the user. If the initialization is successful, the progress in erasing the
blocks is displayed in the Dynamic C STDIO window.
4.2.8 Real-Time Clock
If you plan to use the real-time clock functionality in your application, you will need to set
the real-time clock. You may set the real-time clock using the SETRTCKB.C sample program from the Dynamic C SAMPLES\RTCLOCK folder. The RTC_TEST.C sample program in the Dynamic C SAMPLES\RTCLOCK folder provides additional examples of how
to read and set the real-time clock
4.2.9 TCP/IP Sample Programs

void digOutConfig(int configuration);
Configures any of the 16 configurable I/O channels to be a sinking output. This configuration information is then used by the digOut function to determine whether a given channel is configured to be an
output. If it is not, digOut will prevent the given channel from being used by the digOut function.
The configuration options are described below.
PARAMETER
configuration is a 16-bit parameter for which each bit corresponds to a configurable I/O channel (0–
15). An output channel is enabled by setting the corresponding bit number to a logic one.
Bit 15 = output channel DIO15
Bit 14 = output channel DIO14
Bit 13 = output channel DIO13
Bit 12 = output channel DIO12
Bit 11 = output channel DIO11
Bit 10 = output channel DIO10

Bit 4 = output channel DIO04
Bit 3 = output channel DIO03
Bit 2 = output channel DIO02
Bit 1 = output channel DIO01
Bit 0 = output channel DIO00
The configurable I/O are configured to be sinking by setting the corresponding bit to 1; setting the bit to
0 disables that channel for output operation.
RETURN VALUE

4.4.3 Serial Communication
Library files included with Dynamic C provide a full range of serial communications support. The RS232.LIB library provides a set of circular-buffer-based serial functions. The
PACKET.LIB library provides packet-based serial functions where packets can be delimited by the 9th bit, by transmission gaps, or with user-defined special characters. Both
libraries provide blocking functions, which do not return until they are finished transmitting or receiving, and nonblocking functions, which must be called repeatedly until they
are finished. For more information, see the Dynamic C User’s Manual and Technical Note
213, Rabbit Serial Port Software.
Use the following function calls with the BL2600.
int serMode(int mode);
User interface to set up BL2600 serial communication lines. Call this function after serXOpen().
Whether you are opening one or multiple serial ports, this function must be executed after executing the
last serXOpen function AND before you start using any of the serial ports. This function is non-reentrant.
If Mode 1 is selected, CTS/RTS flow control is exercised using the serCflowcontrolOn and
serCflowcontrolOff functions from the RS232.LIB library.
PARAMETER
mode is the defined serial port configuration.

4.4.4 A/D Converter Inputs
void anaInConfig(int ch_pair, int opmode);
Configures an A/D converter input channel pair for a given mode of operation. This function must be
called before accessing the A/D converter chip.
NOTE: If you plan to configure the D/A converter chip using anaOutConfig, you must
call anaOutConfig before executing anaInConfig. This is because the A/D converter uses internal channels 4–7 on the D/A converter chip to bias the A/D converter
input circuit.
PARAMETERS
ch_pair are the channel pairs:
0 = channels 0 and 1
1 = channels 2 and 3
2 = channels 4 and 5
3 = channels 6 and 7
opmode selects the mode of operation for the channel pair on A/D converter:
0 = Single-Ended unipolar (0–10 V)
1 = Single-Ended bipolar (±10 V)
2 = Differential bipolar (±20 V)
3 = 4–20 mA

4.4.5 D/A Converter Outputs
int anaOutConfig(char configuration, int mode);
Configures the D/A converter chip for a given output voltage range, 0–10 V or ±10 V, and loads the calibration data for use by the D/A converter API functions. This function must be called before accessing
any of the D/A converter channels.
NOTE: If you are using the analog outputs, you must configure the D/A converter chip
using the anaOutConfig function before executing anaInConfig to configure the
A/D converter chip. This is because the A/D converter chip uses internal channels 4–7
on the D/A converter chip to bias the A/D converter input circuit, and the correct configuration of the A/D converter would be affected if the D/A converter configuration
was changed later.
PARAMETERS
configuration sets the output configuration as follows:
0 = unipolar operation. (0–10V and 4–20 mA)
1 = bipolar operation. (±10V and 4–20 mA)
NOTE: When the D/A converter is configured for bipolar operation, the 4–20 mA channels change from 12-bit to 11-bit resolution.
mode is the mode of operation:
0 = asynchronous—an output is updated at the time data are written to the given channel
1 = synchronous—all outputs are updated with data previously written when the anaOutStrobe
function is executed.
RETURN VALUE

4.4.6 SRAM Use
The BL2600 model and some memory variations described in Section 1.2.2 have a batterybacked data SRAM and a program-execution SRAM. Dynamic C provides the protected keyword to identify variables that are to be placed into the battery-backed
SRAM. The compiler generates code that maintains two copies of each protected variable
in the battery-backed SRAM. The compiler also generates a flag to indicate which copy of
the protected variable is valid at the current time. This flag is also stored in the batterybacked SRAM. When a protected variable is updated, the “inactive” copy is modified, and
is made “active” only when the update is 100% complete. This assures the integrity of the
data in case a reset or a power failure occurs during the update process. At power-on the
application program uses the active copy of the variable pointed to by its associated flag.
The sample code below shows how a protected variable is defined and how its value can
be restored.
protected nf_device nandFlash;
int main() {
...
_sysIsSoftReset();
// restore any protected variables
The bbram keyword may also be used instead if there is a need to store a variable in battery-backed SRAM without affecting the performance of the application program. Data
integrity is not assured when a reset or power failure occurs during the update process.
Additional information on bbram and protected variables is available in the Dynamic C
User’s Manual.
4.4.7 NAND Flash Drivers
The Dynamic C NANDFlash\NFLASH.LIB library is used to interface to NAND flash
memory devices on the RCM3365 and the RCM3375. The function calls were written specifically to work with industry-standard flash devices with a 528-byte page program and
16896-byte block erase size. The NAND flash function calls are designed to be closely
cross-compatible with the newer serial flash function calls found in the SFLASH.LIB
library. These function calls use an nf_device structure as a handle for a specific NAND
flash device. This allows multiple NAND flash devices to be used by an application.
More information on these function calls is available in the Dynamic C Function Reference Manual.

5. USING THE TCP/IP FEATURES
Chapter 5 discusses using the TCP/IP features on the BL2600
and BL2610 boards. The TCP/IP feature is not available on
BL2610.
5.1 TCP/IP Connections
Before proceeding you will need to have the following items.
• If you don’t have Ethernet access, you will need at least a 10Base-T Ethernet card
(available from your favorite computer supplier) installed in a PC.
• Two RJ-45 straight-through CAT 5/6 Ethernet cables and a hub, or an RJ-45 crossover
CAT 5/6 Ethernet cable.
The CAT 5/6 Ethernet cables and Ethernet hub are available from Rabbit in a TCP/IP tool
kit. More information is available at www.rabbit.com.
1. Connect the AC adapter and the programming cable as shown in Chapter 2, “Getting
Started.”
2. Ethernet Connections
If you do not have access to an Ethernet network, use a crossover CAT 5/6 Ethernet cable
to connect the BL2600 to a PC that at least has a 10Base-T Ethernet card.
If you have Ethernet access, use a straight-through CAT 5/6 Ethernet cable to establish an
Ethernet connection to the BL2600 from an Ethernet hub. These connections are shown in
Figure 23.

The PC running Dynamic C through the serial programming port on the BL2600 does not
need to be the PC with the Ethernet card.
3. Apply Power
Plug in the AC adapter. The BL2600 is now ready to be used.
NOTE: A hardware RESET is accomplished by unplugging the AC adapter, then plugging it back in, or by momentarily grounding the board reset input at pin 9 on screw terminal header J2.
When working with the BL2600, the green LNK light is on when a program is running and
the board is properly connected either to an Ethernet hub or to an active Ethernet card. The
orange ACT light flashes each time a packet is received.

5.2 TCP/IP Sample Programs
We have provided a number of sample programs demonstrating various uses of TCP/IP
for networking embedded systems. These programs require that you connect your PC and
the BL2600 together on the same network. This network can be a local private network
(preferred for initial experimentation and debugging), or a connection via the Internet.
5.2.1 How to Set IP Addresses in the Sample Programs
With the introduction of Dynamic C 7.30 we have taken steps to make it easier to run
many of our sample programs. You will see a TCPCONFIG macro. This macro tells
Dynamic C to select your configuration from a list of default configurations. You will
have three choices when you encounter a sample program with the TCPCONFIG macro.
1. You can replace the TCPCONFIG macro with individual MY_IP_ADDRESS,
MY_NETMASK, MY_GATEWAY, and MY_NAMESERVER macros in each program.
2. You can leave TCPCONFIG at the usual default of 1, which will set the IP configurations to 10.10.6.100, the netmask to 255.255.255.0, and the nameserver and
gateway to 10.10.6.1. If you would like to change the default values, for example, to
use an IP address of 10.1.1.2 for the BL2600 board, and 10.1.1.1 for your PC, you
can edit the values in the section that directly follows the “General Configuration”
comment in the TCP_CONFIG.LIB library. You will find this library in the
LIB\TCPIP directory.
3. You can create a CUSTOM_CONFIG.LIB library and use a TCPCONFIG value greater
than 100. Instructions for doing this are at the beginning of the TCP_CONFIG.LIB
library in the LIB\TCPIP directory.
There are some other “standard” configurations for TCPCONFIG that let you select different features such as DHCP. Their values are documented at the top of the
TCP_CONFIG.LIB library in the LIB\TCPIP directory. More information is available in
the Dynamic C TCP/IP User’s Manual.

5.2.2 How to Set Up your Computer’s IP Address for a Direct Connection
When your computer is connected directly to the BL2600 via an Ethernet connection, you
need to assign an IP address to your computer. To assign the PC the address
10.10.6.101 with the subnetmask 255.255.255.0, do the following.
Click on Start > Settings > Control Panel to bring up the Control Panel, and then
double-click the Network icon. Depending on which version of Windows you are using,
look for the TCP/IP Protocol/Network > Dial-Up Connections/Network line or tab.
Double-click on this line or select Properties or Local Area Connections > Properties
to bring up the TCP/IP properties dialog box. You can edit the IP address and the subnet
mask directly. (Disable “obtain an IP address automatically”.) You may want to write
down the existing values in case you have to restore them later. It is not necessary to edit
the gateway address since the gateway is not used with direct connect.

5.2.3 Run the PINGME.C Demo
Connect the crossover cable from your computer’s Ethernet port to the BL2600’s RJ-45
Ethernet connector. Open this sample program from the SAMPLES\TCPIP\ICMP folder,
compile the program, and start it running under Dynamic C. When the program starts running, the green LNK light on the BL2600 should be on to indicate an Ethernet connection
is made. (Note: If the LNK light does not light, you may not have a crossover cable, or if
you are using a hub perhaps the power is off on the hub.)
The next step is to ping the board from your PC. This can be done by bringing up the MSDOS window and running the ping program:
ping 10.10.6.100
or by Start > Run
and typing the command
ping 10.10.6.100
Notice that the orange ACT light flashes on the BL2600 while the ping is taking place, and
indicates the transfer of data. The ping routine will ping the board four times and write a
summary message on the screen describing the operation.

5.2.4 Running More Demo Programs With a Direct Connection
The program SSI.C (SAMPLES\BL2600\TCPIP\) demonstrates how to make the
BL2600 a Web server. This program allows you to turn the LEDs on an attached Demonstration Board from the Tool Kit on and off from a remote Web browser. The LEDs on the
Demonstration Board match the ones on the Web page. Follow the instructions included
with the sample program. As long as you have not modified the TCPCONFIG 1 macro in
the sample program, enter the following server address in your Web browser to bring up
the Web page served by the sample program.
http://10.10.6.100.
Otherwise use the TCP/IP settings you entered in the TCP_CONFIG.LIB library.
The sample program SMTP.C (SAMPLES\BL2600\TCPIP\) allows you to send an E-mail
when a switch on the Demonstration Board is pressed. Follow the instructions included
with the sample program.
The sample program TELNET.C (SAMPLES\BL2600\TCPIP\) allows you to communicate with the BL2600 using the Telnet protocol. This program takes anything that comes
in on a port and sends it out Serial Port C. It uses a digital input to indicate that the TCP/IP
connection should be closed and a digital output to toggle a LED to indicate that there is
an active connection.
Follow the instructions included with the sample program. Run the Telnet program on
your PC (Start > Run telnet 10.10.6.100). As long as you have not modified the
TCPCONFIG 1 macro in the sample program, the IP address is 10.10.6.100 as shown;
otherwise use the TCP/IP settings you entered in the TCP_CONFIG.LIB library. Each
character you type will be printed in Dynamic C's STDIO window, indicating that the
board is receiving the characters typed via TCP/IP.
5.3 Where Do I Go From Here?
NOTE: If you purchased your BL2600 through a distributor or Rabbit partner, contact
the distributor or partner first for technical support.
If there are any problems at this point:
• Use the Dynamic C Help menu to get further assistance with Dynamic C.
• Check the Rabbit Technical Bulletin Board and forums at www.rabbit.com/support/bb/
and at www.rabbit.com/forums/.
• Use the Technical Support e-mail form at www.rabbit.com/support/questionSubmit.shtml.
If the sample programs ran fine, you are now ready to go on.
Additional sample programs are described in the Dynamic C TCP/IP User’s Manual.
Refer to the Dynamic C TCP/IP User’s Manual to develop your own applications. An
Introduction to TCP/IP provides background information on TCP/IP, and is available on
the Web site.

0.25
It is recommended that you allow for an “exclusion zone” of 0.25" (6 mm) around the
BL2600 in all directions when the BL2600 is incorporated into an assembly that includes
other components. This “exclusion zone” that you keep free of other components and
boards will allow for sufficient air flow, and will help to minimize any electrical or EMI
interference between adjacent boards. An “exclusion zone” of 0.12" (3 mm) is recommended below the BL2600. Figure A-2 shows this “exclusion zone.”

A.2 Conformal Coating
The areas around the crystal oscillator and the battery backup circuit on the BL2600 module have had the Dow Corning silicone-based 1-2620 conformal coating applied. The conformally coated areas are shown in Figure A-4. The conformal coating protects these
high-impedance circuits from the effects of moisture and contaminants over time.

APPENDIX B. POWER SUPPLY
Appendix B describes the power circuitry provided on the
BL2600.
B.1 Power Supplies
Power is supplied to the BL2600 via the friction-lock connector at J12. The BL2600 is
protected against reverse polarity by a diode at D1 as shown in Figure B-1.

Figure B-1. BL2600 Power Supply
The input voltage range is from 9 V to 36 V. A switching power regulator is used to provide +5 V for the BL2600 logic circuits. In turn, the regulated +5 V DC power supply is
used to drive a regulated +3.3 V power supply and ±12 V power supplies used by the opamps driving the digital outputs.
The digital ground and the analog ground share a single split ground plane on the board,
with the analog ground connected at a single point to the digital ground by a 0  resistor
(R57). This is done to minimize digital noise in the analog circuits and to eliminate the
possibility of ground loops. External connections to analog ground are made on a polarized friction-lock connector at J8.
User’s Manual
87
B.1.1 Power for Analog Circuits
Power to the analog circuits is provided by way of a one-stage low-pass filter, which
isolates the analog section from digital noise generated by the other components. The analog +5 V supply powers the D/A converter, and is not accessible to the user. The A/D converter is powered by the regulated +3.3 V supply, and supplies the +2.048 V reference
violate from which the 1.667 V and 2.5 V reference voltages for the D/A converter output
circuits are derived.
B.2 Batteries and External Battery Connections
The SRAM and the real-time clock on the BL2600 module have battery backup. Power to
the SRAM and the real-time clock (VRAM) is provided by two different sources, depending
on whether the main part of the BL2600 is powered or not. When the BL2600 is powered
normally, and the +3.3 V supply is within operating limits, the SRAM and the real-time
clock are powered from the +3.3 V supply. If power to the board is lost or falls below 2.93 V
(2.63 V on the BL2610), the VRAM and real-time clock power will come from the battery.
The reset generator circuit controls the source of power by way of its /RESET output signal.
A replaceable 950 mA·h lithium battery provides power to the real-time clock and SRAM
when external power is removed from the circuit board. The drain on the battery is typically
less than 10 µA when there is no external power applied to the BL2600, and so the expected
shelf life of the battery is
950 mA·h
------------------------ = 9.0 years.
12 µA
B.2.1 Replacing the Backup Battery
The battery is user-replaceable, and is fitted in a battery holder. To replace the battery, lift
up on the spring clip and slide out the old battery. Use only a Panasonic CR2477 or equivalent replacement battery, and insert it into the battery holder with the + side facing up.
NOTE: The SRAM contents and the real-time clock settings will be lost if the battery is
replaced with no power applied to the BL2600. Exercise care if you replace the battery
while external power is applied to the BL2600.
CAUTION: There is an explosion danger if the battery is short-circuited, recharged,
or replaced incorrectly. Replace the battery only with the same type or an equivalent
type recommended by the battery manufacturer. Dispose of used batteries according
to the battery manufacturer’s instructions.
Cycle the main power off/on on the BL2600 whenever you replace the backup battery.
This step will minimize the current drawn by the real-time clock oscillator circuit from the
backup battery should the BL2600 experience a loss of main power.
NOTE: Remember to cycle the main power off/on any time the BL2600’s RabbitCore
module is removed from the main board since removing the RabbitCore module
disconnects power to its real-time clock oscillator.

Keep in mind that the BL2600 draws 377 mA from the Vcc supply, and that the diode at D41
(shown in Figure B-1) can handle at most 1 A at VRAW, so that leaves the remaining current
capacity to be shared among the DCIN and Vcc pins on friction-lock connector terminals
J5 and J7. Table B-1 lists the available current at DCIN based on the current drawn at Vcc.

APPENDIX D. RABBITNET
D.1 General RabbitNet Description
RabbitNet is a high-speed synchronous protocol developed by Rabbit to connect peripheral cards to a master and to allow them to communicate with each other.
D.1.1 RabbitNet Connections
All RabbitNet connections are made point to point. A RabbitNet master port can only be
connected directly to a peripheral card, and the number of peripheral cards is limited by
the number of available RabbitNet ports on the master.

User’s Manual
95
Use a straight-through CAT 5/6 Ethernet cable to connect the master to slave peripheral
cards, unless you are using a device such as the OP7200 that could be used either as a
master or a slave. In this case you would use a crossover CAT 5/6 Ethernet cable to
connect an OP7200 that is being used as a slave.
Distances between a master unit and peripheral cards can be up to 10 m or 33 ft.
D.1.2 RabbitNet Peripheral Cards
• Digital I/O
24 inputs, 16 push/pull outputs, 4 channels of 10-bit A/D conversion with ranges of
0 to 10 V, 0 to 1 V, and -0.25 to +0.25 V. The following connectors are used:
Signal = 0.1" friction-lock connectors
Power = 0.156" friction-lock connectors
RabbitNet = RJ-45 connector
• A/D converter
8 channels of programmable-gain 12-bit A/D conversion, configurable as current measurement and differential-input pairs. 2.5 V reference voltage is available on the connector. The following connectors are used:
Signal = 0.1" friction-lock connectors
Power = 0.156" friction-lock connectors
RabbitNet = RJ-45 connector
• D/A converter
8 channels of 0–10 V 12-bit D/A conversion. The following connectors are used:
Signal = 0.1" friction-lock connectors
Power = 0.156" friction-lock connectors
RabbitNet = RJ-45 connector
• Display/Keypad interface
Allows you to connect your own keypad with up to 64 keys and one character liquid
crystal display from 1 × 8 to 4 × 40 characters with or without backlight using standard
1 × 16 or 2 × 8 connectors. The following connectors are used:
Signal = 0.1" headers or sockets
Power = 0.156" friction-lock connectors
RabbitNet = RJ-45 connector
• Relay card
6 relays rated at 250 V AC, 1200 V·A or 100 V DC up to 240 W. The following connectors are
used:
Relay contacts = screw-terminal connectors
Power = 0.156" friction-lock connectors

SBC BL2600
D.2 Physical Implementation
There are four signaling functions associated with a RabbitNet connection. From the master’s point of view, the transmit function carries information and commands to the peripheral card. The receive function is used to read back information sent to the master by the
peripheral card. A clock is used to synchronize data going between the two devices at high
speed. The master is the source of this clock. A slave select (SS) function originates at the
master, and when detected by a peripheral card causes it to become selected and respond
to commands received from the master.
The signals themselves are differential RS-422, which are series-terminated at the source.
With this type of termination, the maximum frequency is limited by the round-trip delay
time of the cable. Although a peripheral card could theoretically be up to 45 m (150 ft)
from the master for a data rate of 1 MHz, Rabbit recommends a practical limit of 10 m
(33 ft).
Connections between peripheral cards and masters are done using standard 8-conductor
CAT 5/6 Ethernet cables. Masters and peripheral cards are equipped with RJ-45 8-pin
female connectors. The cables may be swapped end for end without affecting functionality.
D.2.1 Control and Routing
Control starts at the master when the master asserts the slave select signal (SS). Then it
simultaneously sends a serial command and clock. The first byte of a command contains
the address of the peripheral card if more than one peripheral card is connected.
A peripheral card assumes it is selected as soon as it receives the select signal. For direct
master-to-peripheral-card connections, this is as soon as the master asserts the select signal. The connection is established once the select signal reaches the addressed slave. At
this point communication between the master and the selected peripheral card is established, and data can flow in both directions simultaneously. The connection is maintained
so long as the master asserts the select signal.

D.3 Function Calls
The function calls described in this section are used with all RabbitNet peripheral cards,
and are available in the RNET.LIB library in the Dynamic C RABBITNET folder.
int rn_init(char portflag, char servicetype);
Resets, initializes, or disables a specified RabbitNet port on the master single-board computer. During
initialization, the network is enumerated and relevant tables are filled in. If the port is already initialized,
calling this function forces a re-enumeration of all devices on that port.
Call this function first before using other RabbitNet functions.
PARAMETERS
portflag is a bit that represents a RabbitNet port on the master single-board computer (from 0 to the
maximum number of ports). A set bit requires a service. If portflag = 0x03, both RabbitNet ports 0
and 1 will need to be serviced.
servicetype enables or disables each RabbitNet port as set by the port flags.
0 = disable port
1 = enable port
RETURN VALUE
0
int rn_device(char pna);
Returns an address index to device information from a given physical node address. This function will
check device information to determine that the peripheral card is connected to a master.
PARAMETER
pna is the physical node address, indicated as a byte.
7,6—2-bit binary representation of the port number on the master
5,4,3—Level 1 router downstream port
2,1,0—Level 2 router downstream port
RETURN VALUE
Pointer to device information. -1 indicates that the peripheral card either cannot be identified or is not
connected to the master.
SEE ALSO
rn_find

The status byte from the previous command. -1 means that device information indicates the peripheral
card is not connected to the master.
SEE ALSO
rn_hitwd, rn_sw_wdt
int rn_hitwd(int handle, char *count);
Hits software watchdog. Set the timeout period and enable the software watchdog prior to using this
function. This function will check device information to determine that the peripheral card is connected to
a master.
PARAMETERS
handle is an address index to device information. Use rn_device() or rn_find() to establish the
handle.
count is a pointer to return the present count of the software watchdog timer. The equivalent time left in
seconds can be determined from count × 0.025 seconds.
RETURN VALUE
The status byte from the previous command. -1 means that device information indicates the peripheral
card is not connected to the master.
