INSTALLATION
INTERNAL INSTALLATION
Installation of the radar within the sign should be in
accordance with the table below which specifies the
spacing (D) of the radar module PCB assembly from the
inside front surface of the sign. These measurements are
based upon a typical polycarbonate fascia and have been
tested to provide optimum radar performance.
D=15mm
72mm
62mm
In the instance of different thickness front panel materials,
customers are advised to contact AGD systems for further
information and technical support.
55mm
Standard fixing of the radar module is based upon a set
of four mounting holes with the dimensions shown in the
diagram on the right.

The relatively wide beam profile of the K-band radar module ensures good detection coverage of single or dual lane
approaches with relatively little adjustment of the sign in relation to the direction of approaching targets.
Mounting of the radar within the sign is recommended at between two and five metres from the ground (optimum 3m).

User configuration is via
three switches;
Rotary switch 1 - This sets the
Low Speed Threshold (LST)
of the radar. The low speed
threshold is that speed below
which the radar will not detect
targets. Eg if the LST is set to
55km/hr the radar will only
activate the output for targets
travelling at 55km/hr or greater.
Note: to convert from kph to
mph please use the correct DIP
switch #1 setting (On = kph Off
= mph)

COMMAND STRUCTURE
The *HELP command
As an example, the window below shows the command *HELP=3 requesting the third help page and the
response to the command. A list of possible commands (both star * and non-star commands) will be shown
on the terminal screen in response to different *help commands. It is important to note that the *help command
will show a full list of diagnostic and configuration commands. Users should be aware that a full list of user
commands is shown on page 19 and that no attempt should be made to alter any other settings without prior
authorisation from AGD Systems.
20
USER CONFIGURATION
COMMAND STRUCTURE
User commands or ‘star’ commands are prefaced with an asterisk (*), the format in lower case is as follows:
*<command field><command suffix><data field(s)><cr>
The command field defines the function of the command and may be up to 16 characters long. The content of
the command field can be either machine or human readable (see command list on page 16 for examples).
The command field may only contain alphanumeric characters and may not contain any spaces or suffix
characters. If multiple data fields are required, these should be comma delimited.
The command suffix defines the type of action which a command performs, and is denoted by a single
character. There are five types of suffix:
Suffix Character Action Description
?
Query Get current value or status information
=
Set Set new value
$
Info Get more information about command
^
Default Set value to default
!
Do Action / Execute the command
Not all commands need to support all five suffix types - see explanation on page 19 for more information or
product responses to unsupported suffix types.
When sending a command, the data fields will be in either decimal or hexadecimal. If multiple data fields are
required, these should be comma delimited.
The general response to a star command in upper case is as follows:
#<COMMAND FIELD><COMMAND SUFFIX><DATA FIELD(S)><CR>
The radar will respond with the same command field and command suffix as defined in the star command
and will append the required data fields onto the end of the reply. The response to a star command will be
prefixed by a hash (#) in order to distinguish the response from the command.#ERROR<space><command

Querying and setting parameters
The following example shows querying the opto trigger speed, setting the speed to 30mph and then querying
the speed again to make sure it has been changed. As with all the other examples, the commands sent to
the radar are shown in lower case and the replies are in upper case.
Notes:
• ‘OC’ stands for opto cut-off
• Units are specified by dipswitch position 1 - mph or kph (refer to page 10)

COMMAND STRUCTURE
Restoring a parameter to factory default setting
It is often useful to be able to reset a single parameter back to its factory default, rather than resetting
everything using the ‘defaults’ command. This is achieved using the ^ suffix.
The following example shows querying the opto trigger speed, restoring the default value, and then querying
the speed again to make sure it has been changed.
Notes:
• The set value for the opto trigger speed was 30.
• Default value for the opto trigger speed is 10.
• Units are specified by dipswitch position 1 - mph or kph (see page 10).
24
USER CONFIGURATION
COMMAND STRUCTURE
Speed output messages
From the command list on page 19, it can be seen that there are three different options for generating speed
messages. Setting which message is used is achieved using the ‘*MS’ command, with *MS=0 being used to
disable messages.
There are three main message types, as follows:
• DCFMSxx.xx
• Legacy message for compatibility with older systems
• xx.xx is speed in hexadecimal
• dd
• Decimal, speed only message
• dd is speed in decimal
• *Sddd
• Speed and count message
• ddd is speed in decimal
• outputs *C every time a vehicle passes the radar
The three main message types can be generated at different update rates, depending on the user’s
requirements and processing capabilities. Update rates of 20Hz, 10Hz and 5Hz are available (i.e. 20 messages
per second, 10 messages per second or 5 messages per second).
The first two of the above message types can be configured for operation in single shot mode. Using single
shot mode should generally be avoided as this will only generate a single speed and therefore will not take into
account acceleration or deceleration of the target vehicle.
The final message option provides another speed and count message (type 2). Both type 1 and type 2 messages
are discussed in more detail in the following sections.
25
USER CONFIGURATION
COMMAND STRUCTURE
Speed and count message - type 1
The following example shows type set (which is disabled), and setting the message to type 9.
The messages after the #MS=9 are speed and count messages reported by the 330.
The messages show three successive vehicles passing the radar (indicated by each *C). It should be noted that
each target will have a slight decrease in speed just before the count message is sent - This is caused by the
cosine effect as the vehicle passes the radar.
This speed mode is recommended for use in situations where the vehicle speed is being displayed on a
variable message sign.
26
USER CONFIGURATION
COMMAND STRUCTURE
Speed and count message - type 2
The following example shows querying the current message type (which is disabled), and setting the message
to type 12 (speed and count message type 12 - refer to table on previous) The messages after the #MS=12
are reported by the 330 per target vehicle. The message type is then disabled by the *MS=0, this then is
acknowledged by the #MS=0
The above messages have the following construction:
<lane number><vehicle count><direction><speed of vehicle><spare fields><cr>
One message is sent per target vehicle passing the radar. This speed mode is recommended for use in
situations where logging of speed and count data is required, and a simple opto trigger can also be used for the
variable message sign.
27
USER CONFIGURATION
COMMAND STRUCTURE
Setting up the sensitivity and cut-off values of the opto and speed outputs
The 330 can be setup to trigger at different sensitivities and speeds for the opto and RS422 speed outputs. This
may be advantageous in situations where a variable message sign is required to trigger for all speeds above,
say, 40mph (using the opto output) but the serial output is required for all vehicles above, say, 10mph.
Care must be taken when adjusting the sensitivity settings to ensure that a stable detection is seen throughout
the required range of operation for both opto and speed outputs. For example, if too high a sensitivity is chosen
for the speed output but the opto sensitivity is set correctly, the 330 will appear to detect correctly (the opto will
trigger and the LED, if enabled, will illuminate) but no speed messages will be transmitted.
28
USER CONFIGURATION
COMMAND STRUCTURE
Setting up the count function
The screenshot below shows the diagnostics message with a single vehicle passing the radar. These diagnostics
can be activated by using the command @. Most of the fields shown are not important for count - the only data
of significant interest is the string down the left hand side reading AAAAAAVGGGGGG. This sequence of A-V-G
components indicates that a vehicle has passed the radar. Different vehicles present different target signatures
to the radar, so the exact number of each component (A,V,G) is unimportant, but each passing vehicle should
generate a similar effect. If this feature is not observed then the sign/radar inclination to the carriageway should
be adjusted further within the recommended range.
To exit the diagnostics mode press ‘carriage return’ or ‘enter’ to return the radar to the preset message and
operational modes.
It is worth noting that if the radar doesn’t generate the A>V>G aspect of the diagnostics message,
then a count will not be generated for that target.
29
USER CONFIGURATION
COMMAND STRUCTURE
Low speed target measurement - introduction
If the 330 is equipped with firmware version 3 or higher (MI-097-n where n = version number), it is possible to make
lower speed measurements than with earlier versions of firmware. Note that care must be taken in this instance
as the radar may create false triggers on targets other than those intended for detection (moving tree branches,
pedestrians, fluorescent lights if indoors etc.)
These versions of firmware are intended to allow evaluation of low speed measurement capability and it is important
for the user to understand the special commands and options associated with them. This is covered in the following
sections.
The ‘status’ command is a useful tool for displaying most of the important parameters within the radar as shown
below. Users will normally need to adjust these commands to configure the radar for their own applications”
Notes:
•Threshold level (*MN) relates to the maximum sensitivity of the radar and should not need to be
adjusted - use opto and speed ‘range’ commands instead (*ON \ *SN)
• Low speed bin limit is for initial filtering of very low speed targets (default 5 mph)
•The opto trigger and speed trigger fields in the above message relate to the cut-off and ‘range’ values
(*OC / *ON or *SC / *SN).
30
USER CONFIGURATION
COMMAND STRUCTURE
Low speed target measurement - normal mode
With version 3 or higher firmware, the radar can be set to trigger at a minimum speed of / or greater than
3mph / 5kph.
If a speed threshold of less than 5mph / 8kph is required, the low speed bin limit (*LS must also be adjusted to allow
measurement below the default value of 5. The screenshot below shows this adjustment:
The low speed bin limit can be adjusted to as low as 1 (*LS=1) but it is recommended that the same value is used
as required for the speed cut-off e.g. for *SC=3 set *LS=3.
Note that the low speed bin limit is currently not stored in the EEPROM of the 330, so if power is cycled to the
unit (or the reboot command used) then the radar will resume operation with the default value of 5mph / 8kph.
31
USER CONFIGURATION
COMMAND STRUCTURE
Low speed target measurement - low speed mode
There may be situations where the minimum low speed of 3 mph is not sufficiently low, or the radar appears to
false trigger. Under these circumstances, the performance of the radar may be improved by using low speed
mode, but care must be exercised as the radar may create false triggers from targets other than those intended
for detection (moving tree branches, pedestrians etc...).
Another caveat with low speed mode is that the maximum target speed measurable is limited to 60 mph, and if faster
targets are present these will be ignored. The following screenshot shows the command sequence required to allow
the radar to operate in low speed mode. It is important to follow carefully the ‘overrideon’ and ‘unitshalf’ command
sequence to allow special values of *BT / *LS / *SC to be set.
Note that the low speed bin limit, override mode and measurement units are not stored in the EEPROM of the 330,
so if power is cycled to the unit (or the reboot command used) then the radar will resume operation with the default
value of *LS=5.
However the value for *BT (bin track separation) is stored in the EEPROM. If the radar is switched back to normal
mode, the default value of *BT=2 for this parameter must be restored (using *BT^) otherwise erroneous operation
will result.
32
HELP
TROUBLESHOOTING
Our VAS sign does not display when the vehicles are travelling above the speed limit.
Check that the unit is connected to the power supply and that it is receiving 12/24Vdc
Check the RS422 connection is made and that the settings are correct (Baud rate etc…)
Check the opto connections between the radar and the VAS
Check the *LS, *OC, *ON and *SC settings if using RS422
Check the switch settings on the rear of the 330 to ensure they match the required parameters
How do I decide which is the best output message mode and type for my application.
Refer to the “Speed output messages” section on page 25.
How does the AGD330 interface with host equipment.
The radar is supplied with a six way power and four way data cable set. The electrical, opto output and
RS422 connections are detailed on page 8. For initial evaluation we also recommend the use of a DTECH
DT-5019 USB to RS422 converter supplied as AGD part number CA-250 and the terminal emulator
‘TeraTerm’ which can be downloaded from www.agd-systems.com/teraterm.
For what range of speeds will the AGD330 detect.
The trigger speed for the opto output has a factory default of 10mph but can be set via the RS422
interface using the *OC command to between 10-120mph (16-192kph). Alternatively, a number of pre-set
values are selectable using rotary switch one (see page 9 for details).
What is the maximum range of the radar and how can I adjust this.
This is typically 180m for a standard saloon car but will be dependent on vehicle type and approach
speed. The range for opto trigger output can be adjusted using rotary switch 2 or by using the *ON
command in the range 500-1500 (factory default is 1500 - minimum range).
I have connected to the radar but receive no RS422 output messages when vehicles pass the radar.
Check that the unit is powered on
Check DIP switch 2 is ON and DIP switch 3 is OFF
Check the cable connections
Check that the RS422 port is configured correctly (see page 15)
Check that your USB settings are correct
What are the optimum mounting positions for the radar within our VAS sign and in relation to the carriageway.
The radar should be mounted in accordance with the dimensions specified on page 7 in relation to the
front panel of the sign (15mm +/- 1mm) and at a height of approximately three metres above the
carriageway on a pole adjacent to the lane for detection.
When viewing the speed output message via RS422 I only appear to receive speed=0 messages after vehicles
have passed the radar.
The range setting *SN is incorrectly set. Adjust to longer range (lower number) using the *SN command
(factory default is 1500 - minimum range).
33
HELP
TROUBLESHOOTING
What is the *Monitor command
The *Monitor? command shows the amount of time the 330 will wait since it’s last target detection before
it disables the RS422 output and the opto. The default setting is 4320 minutes (72hrs). The 330 will still
trigger when vehicles pass the radar at speeds greater than the trigger speed settings and the monitor
timer will reset at this point.
Why after a certain period of time does the detector stop transmitting speed data
The *Monitor command may require changing. Using *Monitor^ will reset this to 4320 minutes,
alternatively the user can set this as required.
We are detecting pedestrians when the LST is set at a low value, how do we ignore these targets
The sensitivity of the radar can be adjusted (decreased) via the rotary switch or the *SN/*OC/*SC
commands until these are no longer detected.

IMPORTANT SAFETY INFORMATION
LOW POWER NON-IONISING RADIO TRANSMISSION AND SAFETY
Concern has been expressed in some quarters that low power radio frequency transmission may constitute
a health hazard. The transmission characteristics of low power radio devices is a highly regulated environment
for the assurance of safe use.
There are strict limits on continuous emission power levels and these are reflected in the testing specifications
that the products are approved to. These type approval limits are reflected in the product specifications required
for a typical geographic area such as those for the EU (ETS300:440), for the USA (FCC part 15c) and for Australia/
New Zealand (AS/NZS 4268). The limits adopted in these specifications are typically replicated in many other
localized specifications.
The level of safe human exposure to radio transmission is given by the generally accepted guidelines issued by
the International Commission on Non-Ionizing Radiation Protection (ICNIRP). This body has issued guidance
for limiting exposure to time-varying electric, magnetic and electromagnetic fields (up to 300 GHz) which are
quoted below.

Note 3Calculation is made on the assumption antenna is a point source therefore the actual value is likely to be significantly
less than that quoted. Note that a theoretical max level at a 5cm distance (which gives 0.318mW/cm2) is at a point in
the field where the radar beam is not properly formed.
Note 4 Comparison for product model 330 operating in the band typically 24.050GHz to 24.250GHz
From the table it can be seen that it is extremely unlikely that a potentially hazardous situation could occur owing
to the use of such low power devices.
It is considered to be good practice not to subject humans to radiation levels higher than is necessary. In a works
environment where multiple equipment on soak test are to be encountered then it is considered good practice to
contain the equipment in an appropriate enclosure lined with radar absorbing material.
