335
The AGD335 is a compact FMCW low power digital
radar which operates in the K-Band 24GHz.
The radar processing consumes approximately
120mW whilst maintaining the detection range of
140m and update rate of 20Hz.
The power can be reduced further by setting the
event update rate accordingly between 12-28Hz.
Configuration of operational parameters is via an
RS232 serial interface. Detect output
options include opto-isolator
and RS232 serial
communications.

Set your power supply to the
correct voltage. The radar’s voltage
of 6V or 12V can be found on the
label at the back of the unit.
Connect the red wire from the
AGD335 to the positive DC supply.
The black wire should be
connected to the negative of this
same supply.
Once powered, the AGD335 front
right LED should flash 5 times.

AGD335-105-000 & AGD335-803-000 models;
Where the AGD335 has no blue port interface, set up is made via the RS232 connection on the flying lead.
The AGD335 adjustable settings can be configured before connection to the host via a PC interface or directly by
the host system, if designed to do so.
For evaluation you can connect the AGD335 directly to the comport via a USB socket on a windows based PC
Plug the USB-end of your CA-194
convertor cable into the USB port
of your computer.
Connect the round, blue plug of
CA-183 to the AGD335 unit, making
sure the plug is screwed down.
Finally, connect the 9-pin female
end of CA-183 to the 9-pin male
end of CA-194

4 SETTING UP COM PORT USING THE RADAR DIAGNOSTIC SOFTWARE
Having identified the relevant COM Port, select it under the Communications Settings Tab
The software’s Baud Rate defaults to 115200 and should need no further adjustment.
You can now select the AGD Speedometer Tab to get real-time radar diagnostics.
5TESTING THE CONNECTION WITH THE RADAR
Terminal Emulator
(For further guidance
please refer to the
Connectivity Section)
To test communications with the detector, type AGD into the command line and press <ENTER>
The Radar will respond with its product description in the terminal window.
Please see the User Configuration section for radar commands to set the radar parameters.
The Speedometer needle will reflect the detected speed of any targets.
Please note that hand-wave tests will not activate the radar due to its complex nature.

INSTALLATION
MOUNTING HEIGHT, ANGLES, CLEARANCE
The radar should be mounted on a firm structure. The front
face of the radar should be vertical i.e. perpendicular to the
road before you begin site specific adjustments.
The radar should point down the road towards the furthest
point where target detection is required.
The radar has a relatively narrow azimuth field of view of 12
degrees. Within this angle the target vehicles should be visible
at the greatest detection distance.
For optimum performance the radar
should be situated on the
nearside of the carriageway with
an unobstructed view of approaching traffic.
Pole Height 3 -5m nominal
Beam ‘width’ 12deg
POWER & WIRING
Cable connections for the AGD335 low-power radar are as detailed below.
AGD335-100-000 & AGD335-800-000 models: 5 way flying lead.
AGD335-105-000 & AGD335-803-000 models: 8 way flying lead.
The current drawn from the radar is less than 20mA typical at 6Vdc with an update rate set to 20Hz.
Please note the cable screen must be connected to earth.
NB RS232 (PC Rx) line should be held at +5V or -5V to operate correctly. 0V results in nothing being transmitted
over the RS232 connection.

INSTALLATION
TYPICAL INSTALLATION
A typical system can be broken down in to 4 main elements.
• The Power Supply.
• The LED display.
• Data Logger (not always required)
• The Radar.
An Opto output is provided to activate when a valid target is detected above the set threshold. In most
applications the Opto switches the control gear to illuminate a Vehicle Actuated Sign or call the appropriate
traffic control signal phase, for example.
If fitted, the RS232 bus can be connected to a data logger to capture target data. This communication line is
also able to send commands to the detector for configuration.
If the AGD335 does not have an RS232 bus, configuration can be made using the port located at the
back of the radar.

CONNECTIVITY
IDENTIFYING COM PORT ON PC
With minor differences, the following instructions can be applied to most Windows versions.
Step 1. Bring up the Computer Management console by right-clicking “My Computer” from the
Start Menu and selecting “Manage”.
Step 2. Select “Device Manager” from the left-hand tree menu.
Step 3. Within the “Ports (COM & LPT)” heading, select the COM Port you wish to change.
Step 4. Right-click on the selected entry & choose “Properties”. Then view the “Port
Settings” tab and click the “Advanced...” button.
Step 5. To remap the COM Port assignment, choose a suitable (unused) COM Port within the
“COM Port Number” drop-down list. Once completed, select “OK” on each open box, and close
the Device Manager.
Note that COM1 & COM2 are typically reserved, though the remainder will only tend to be “in use”
if the associated hardware is connected at that time. For example, assigning your USB-Serial
cable/convertor to use COM6 will then show COM6 as “in use” whether the cable/convertor is
connected or not.
POWER ON TEST (AGD RESPONSE)
When power is established the radar will respond with three actions.
1) Front right LED will flash 5 times
2) Back LED will illuminate for 2 seconds
3) Product and firmware version reported via RS232 port
This report will be done using the radars default baud of
115200. If a different baud rate has been set, the AGD335
will report this value at 115200 before using the set baud rate.
The product will always respond to the “AGD” command via RS232 port.

TERMINAL WALKTHROUGH
This guide demonstrates the configuration of a typical Terminal application, Tera Term Pro 2.3 for Windows
95/NT (onwards). This is a license-free serial communication program available from
http://www.agd-systems.com/teraterm
The steps below assume that Tera Term has been installed following the onscreen prompts.
1. SETUP CONNECTION
Launch Tera Term and find the menu option to
configure the Serial Port. Select the appropriate
COM Port & configure the setup as per the
screenshot.
2. SETUP TERMINAL
Find the menu option to configure the Terminal
Interface. Setup your system are per the screenshot.
This will send & receive messages with the
necessary carriage return character & place
incoming & outgoing messages onto separate lines.

CONNECTIVITY
3. TEST CONNECTION
Test the connection by typing AGD & pressing the
<Enter> key. The detector will respond with model
& version details. If not, check communication &
power cables and ensure Tera Term is configured
correctly from the previous steps.

USER CONFIGURATION
COMMAND STRUCTURE
The Radar features user-adjustable Parameters to
change the way it operates. These are accessed
through Commands, sent via the Serial Connection.
Most commands start with an Asterisk (*).
The radar shows responses to commands using a
Hash (#) prefix.
Commands must be terminated with a carriage return character (<CR>), typically sent when using the <Enter>
key.
The Radar will send a <CR> (carriage return) at the end of a message.
COMMAND TYPES
There are 3 basic “Types” of commands, refelecting the number of ways to interact with a Parameter:
QUERY SET ACTION
Query commands
show a Parameter value
without changing it
Set commands change
a Parameter value
Action commands perform
an operation, often on a
group of Parameters

EXAMPLES
1. GET HELP USING THE RADAR
The HELP command Queries the Radar, returning a list of available commands.
2. QUERYING THE EXISTING LOW SPEED THRESHOLD
Sending *LS to the detector prompts it to respond with the current Low Speed Threshold.

17
USER CONFIGURATION
3. CHANGE THE LOW SPEED THRESHOLD
Adding an argument to the *LS command (55 in the example below), the Radar will Set and confirm a new value.
4. SET ALL PARAMETERS TO THEIR FACTORY DEFAULTS
The *FD command Actions the Radar to restore each Parameter to its factory default.
5. SAVE RADAR SETTINGS
Once operating as required, Parameter values must be committed using the *RM command. This Actions the
Radar to save all Parameters. They will then be available after a reboot/power-failure.
