On the ATE-301 Back Panel Board, the ATE-101 Arduino board need to be placed on
the 50 pins connector indicated with uC. Be aware all 50 pins are correctly connected
and the board is correctly oriented (components on the outside).
The ATE-202 Input Board should be placed on connector CON2 close to the uC board,
with solder side facing each other.
The ATE-201 Relay Boards can be placed on the other 50-pin connectors (CON3 and
CON4).

5V POWER INPUT
The relays on the first module (Back Panel CON3) will be relay 1-4. The relays on the
outside module (Back Panel CON4) will be relay 5-8.
The ATE-202 Input Board has 8 inputs and one common connected to ground. The
Board can be used to measure analog and digital signals. Analog 0V until +3.3Vdc. In
the firmware digital logical level 0 is set at +0,5Vdc or less and logical level 1 at
+2Vdc or more.
The inputs have a 10K pull-up resistor to +3.3Vdc. A switch contact can be connected
directly between input and GND (dry contact input). Also an open collector output can
be connected directly to the input.

Power is not connected. Power can be used as an alternative input to supply power to
the ATE-611 controller. In this case jumpers on all boards must be changed. See the
schematics for information on jumper settings.
Power Supply
A stabilized 5Vdc power supply (like ACDC5012) is required for the ATE-611. With one
relay board maximum current is 300mA and with 2 relay boards 600mA. The 5V
supplies the Relay Board and the Arduino Pro Mini. The 3V3 output of the Arduino Pro
Mini supplies the Input Board with XBee. The output current of 3V3 is limited, which
means the maximum power of the XBee module is 1mW.
All boards have a power on led.

611 Tester
The ATE-611 Tester is a Windows program which can be used to test the controller.
This software and source code can be
downloaded from
www.antratek.com/ate-611.
When an USB XBee Adapter is connected
for the first time, Windows will install the
driver and will give it a port number.
After opening the Tester, type in this port
number and click on Open.
If you do not know the port number, you
can click on List Ports and you will see
the available port(s).
The Tester will read the inputs
continuously and show the results. When
you click on Toggle, you can switch the
relay on and off.
For the relays and inputs, green indicates
contact is closed and red indicates
contact is open.
To change the baud rate of the tester,
click on Baud. To change the baud rate of
the controller, use the SB command as
described below. The default baud rate
of tester, controller and XBee modules is
9600 baud. If you want to change the
baud rate, you need to change the baud
rate of the XBee modules too.
Communicating with the Controller
The Address and Baud Rate of the unit can be set and are stored in the controller’s
memory. By default the controller is listening for serial data at 9600 baud, and has
address 00. The controller will always use 1 Stop Bit, 8 Data Bits and No Parity.
The commands the controller uses are in the form
@AA CC X<CR>
The @ symbol is used to define the start of a command.
AA is the address of the unit from 00 to 99.
ATEATE-611

CC is a two letter command used to determine the command type.
X is a one or more characters which determines the parameter for the command.
<CR> is the carriage return character. This is ASCII character 13, or 0x0d.
Each time a valid command is received the unit will respond with #AA followed by
any values that are requested from the unit.
ON: Relay On Command
This command is used to turn a single relay on. E.g.: @44 ON 1 will turn relay 1 on for
the unit with address 44. It can also be used to turn all the relays on, this occurs
when the parameter value is 0.
OF: Relay Off Command
Similar to the on command this command will turn relays off in the same manner.
E.g.: @44 OF 1 will turn relay 1 off for the unit with address 44, @44 OF 0 will turn all
relays off.
WR: Write Relays Command
The write relays command is used when more than one relay is to be turned on or off
at once. The parameter is a decimal number which, in binary, represents the on and
off status of the 8 relays. The least significant bit of this value controls relay 1. The
most significant bit of the parameter value controls relay 8. A set bit (1) turns the
relay on, a cleared bit (0) turns the relay off.
Example: To turn relays 1, 2 and 6 on (and others off) the binary value required is
00100011. In decimal this is 35. (2^(1-1) + 2^(2-1) + 2^(6-1) = 35). To issue this to a
controller with address 44, the required command is @44 WR 35
IS: Input Status Command
This command will return the status of the inputs. If the parameter is between 1 and
8 then the controller will return a 0 or 1 corresponding to that input. E.g.: @44 IS 1
will return #44 1 if the input is closed (0V), or #44 0 if the input is open (+5V).
If the parameter is 0 then the unit will respond with the status of all the inputs, in
similar form as the Write Relays command. E.g.: If inputs 1 and 2 for the unit are on
then @44 IS 0 will return #44 3. 3 is 0011 in binary, and each bit represents each
input from 4 down to 1.
RS: Relay Status Command
ATEATE-611
611
Manual
Page 9

Much the same as the input status command, this command will return the status of
the relays. If the parameter is between 1 and 8 then the unit will return with a 0 or 1
corresponding to that relay. E.g.: @44 RS 1 will return #44 1 if the relay is on, or #44 0
if the relay is off.
If the parameter to this command is 0 then the unit will respond the same way as the
input status command, but return the status of the relays.
AI: Analog Input Command
The analog input command will read the status of the analog input defined by the
parameter and return it as a value between 0 and 1023. E.g.: @44 AI 1 will return #44
512 if the analog input is reading 50%.
SA: Set Address
Addresses are valid from 01-99. A unit will only respond if its address in memory is
the same as that of the command sent, or if the address of the command sent is 00.
The address is saved to non-volatile memory inside the controller, meaning it will be
preserved even after power is disconnect from the controller.
SB: Set Baud
Parameters from 1 to 10 are valid, corresponding to the following values.
1: 1200 baud
6: 19200 baud
2: 2400 baud
7: 28800 baud
3: 4800 baud
8: 38400 baud
4: 9600 baud (default)
9: 57600 baud
5: 14400 baud
10: 115200 baud
The baud rate is saved to non-volatile memory inside the controller, meaning it will
be preserved even after power is disconnect from the controller.
Serial Terminal Program
You can use a serial terminal program to communicate with the controller. One of the
popular Windows terminal programs is Tera Term. It can be downloaded from
http://ttssh2.sourceforge.jp/. When you have connected the XBee USB adapter and
you start Tera Term, you will get the following screen.

After OK you get an empty screen. Default speed is 9600baud. When you push the
reset button on the Arduino microcontroller, then after a few seconds the version of
the firmware will appear.

Jumper settings
At delivery the jumpers on every board are set for ATE-611 use. The jumpers settings
should be as on the photos above:
ATE-101: 1-3 Vin-5V, 6-5 3V3
ATE-201: 1-2 EXT, 3-4 INT
ATE-202: 7-8 3V3
Loading new firmware
The ATE-611 uses the Arduino Pro Mini (3.3V) which is an Atmel ATmega328
microcontroller with Arduino bootloader. The Arduino is loaded with ATE-611 Sketch.
The source code can be downloaded from www.antratek.com/ate-611. You are free to
modify the code. You can load the modified code or any other code via an USB FTDI
Adapter (3.3V) into the ATE-202 (after removing the XBee) with the Arduino
development environment, available at www.arduino.cc. Before loading it is
recommended to place the Auto Reset jumper on the ATE-101 Carrier Board.
Power on and reset
After power on there will be a short closure of relay 8. Power on reset and manual
reset (button on Arduino Pro Mini) will start the Arduino bootloader to check if the
Arduino development environment is active. During this short time the led on
Arduino Pro Mini will lit. On the same output as the led, relay 8 is connected.
