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.

INSTALLATION
QUICKSTART GUIDE
1CONNECTING POWER
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.

2INSTALLING THE RADAR DIAGNOSTICS SOFTWARE
Download and install the Radar
Diagnostic Software from
www.agd-systems.com/downloads
or from the AGD335 Trial Kit CD.
Install the Software following the
on screen instructions.
Launch the program by clicking
the new desktop icon.
When prompted, select the
AGD335 button

AGD335-100-000 & AGD335-800-000 models;
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
Connect the following conductors
to MS-162
Pin2. Brown
Pin3. Violet
Pin5. Green
Connect the wired MS-162 to
CA-194
Connect CA-194 to the USB on
your PC.
For help identifying your
computer’s COM port, please refer
to the Connectivity Section of this
manual.

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.
