307
The 307 is a compact Doppler vehicle radar which
operates in the K-Band at 24GHz.
It is designed to be robust, cost effective and
highly versatile offering outstanding detection
performance for multiple Intelligent Transport
Systems (ITS) management applications.
Configuration of the unit is via a set of user
selectable switches or RS422. Detect state is
returned via a switched relay or opto isolator
output. RS422 versions provide a serial
interface for parameter setup
and for vehicle speed
outputs.

INSTALLATION
MOUNTING HEIGHT, ANGLES, CLEARANCE
Mount the radar on a firm structure within a recommended height range of 2m-5m. For optimum performance
the radar should be situated on a pole adjacent to the carriageway with an unobstructed view of advancing
traffic. Point the radar down the road towards the furthest point where vehicle detection is required. This is aided
by using the sighting guide on top of the detector. The front face of the radar should be vertical i.e. perpendicular
to the direction of traffic flow before site specific adjustments are made.
The radar has a relatively wide field of view of allowing good vehicle detection coverage of single or dual lane
approaches for the applications indicated. Typical ranges are as shown based on the sensitivity setting selected.

RS422 VERSION - CONNECTING THE RADAR TO A COMPUTER
RS422 - PREPARING THE CONNECTION
A terminal emulator is needed to use RS422 commands. The software
allows the computer to send and receive serial commands with a unit.
AGD’s recommended software can be downloaded and installed from
www.agd-systems.com/teraterm
Common alternatives include HyperTerminal and PuTTY.
The product and firmware version will be reported via RS422 using
the radar’s default baud rate of 9600. If a different baud rate has been
requested or set then the radar will report this value.
(see *BAUD command on page 19)
The product will always respond to the “AGD” command via RS422.
All outgoing commands should end with a carriage return <CR>
character; this is typically the enter/return key of a keyboard,
though may be an advanced option in some emulators.
See Command Details section for more details.

USB port of your computer.
• Connect the ten-way RS422
cable from the radar to the
terminals of the D-type wireable

Power & Wiring section on P6.
• Connect the 9-pin D-socket to
the 9-pin D-plug of CA-250.

USER CONFIGURATION
TERMINAL SETUP
The following Tera Term screenshots will show how to set up and configure the 307 radar detector. These
screenshots were produced using the following terminal settings, in order that the commands sent to the 307
would be shown on the terminal screen along with the responses from the radar.
1: Upon opening TeraTerm, you will
be presented with the following
window
2: Select the “Serial” option and choose which COM port you require

TERMINAL SETUP
3: In the main window, select ‘Setup’
from the top menu and left click on
‘Terminal’
4: In the Terminal setup window,
ensure that Receive is set to CR+LF
and that local echo is active

the correct COM port is selected and
that the options are configured as
below;
Note that the baud rate contained in
this table is indicative of the factory
default setting and not necessarily
what the radars RS422 interface is
set to.
6: In the main window, select ‘Setup’
and ‘General setup’. Ensure that the
correct COM port is selected and use
the drop down menu to select your

7: If you find the display to be too small
or difficult to read, select ‘Setup’ and
‘Font’ and set the font size to suit your
needs.
8: Once you have configured TeraTerm
correctly, and the 307 is connected to
your computer and powered up, press
the ENTER key and TeraTerm should
display the READY message.
Once you have confirmed that the
COM port is configured and working
correctly, it is possible to save the
current settings of the emulator. This
will allow you to quickly re-load the
parameters you have set in order to
facilitate greater ease of maintenance.
9: In the main window, select ‘Setup’
and ‘Save setup’. Select the location
where you want to save the *.ini file,
confirm the filename and click ‘save’.
10: If you want to restore a previous
connection, select ‘Setup’ and
‘Restore setup’. Navigate to the
folder in which you have previously
saved the *.ini file and select the
required file. TeraTerm should now
be configured as per your previous
session.

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

RS422 COMMAND STRUCTURE
• Most commands start with an asterisk <*>
• The radar responds using a hash <#> prefix
• Commands are sent to the radar using the
<Enter> key. (Terminated by the carriage return
character <CR>)
• The radar will send a <CR> at the end of its
response
Commands are built from a few basic blocks:
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

USER CONFIGURATION
RS422 COMMAND DETAILS
AGD
All AGD detectors respond to the basic AGD command. Each unit will respond with specific model details and
firmware version.
Typical response – AGD SYSTEMS LTD 307 Radar Version MI-122-X 30th August 2011
*BAUD
The RS422 output can operate at a number of baud rates. When setting a new baud rate, the unit will
acknowledge the request at the current baud rate, before switching to the new value.
A power-cycle or *REBOOT! command is not normally required after the *BAUD= command.
Typical response – #BAUD?1
*BIDI
An advancing target is one that travels towards the front-face of the detector. A receding target is one that travels
away from the front-face. The 307 can be configured to report advancing targets only, or both advancing and
receding targets. Note that this parameter is also accessible via the switch settings.
Typical response – #BIDI?0
*DETECTTHRESH
Select ‘0’ = medium setting (less sensitive i.e. shorter range typically 100m for a saloon car) or alternatively
select ‘1’ = high setting (more sensitive i.e. longer range typically up to 150m for a saloon car). Note these
settings are synonymous with the RS422 commands if using this option.
Typical response – #DETECTTHRESH?0
*FACTORYDEFAULTS
This command will set all parameters back to their default values and commit them to flash memory.
A *SAVE! command is not required after issuing this command.
Typical response – #FACTORYDEFAULTS!Done
*HELP
This displays a table of valid commands along with a short description of each.
Typical response – #HELP...
*HOLDTIME
Hold Time states how long the unit stays in detect after the target has left its field of view. Hold Time is
expressed in milliseconds, where 1000ms = 1s. Note that this parameter is also accessible via the switch
settings.
Typical response – #HOLDTIME?500

20
USER CONFIGURATION
RS422 COMMAND DETAILS
*LED
This command will determine whether the front LED is illuminated during a detect state.
Note that this parameter is also accessible via the switch settings.
Typical response – #LED?0 where 0 = off and 1 = on
*LOWSPEED
This command accesses the Low Speed threshold/cutoff in kph. The radar will ignore targets travelling below
this value, and respond when a target is detected above this speed.
Typical response – #LOWSPEED?33
*MM
This command states which value to output over an RS422 connection, where:
1 = Instantaneous speed of the fastest target
2 = Current speed of the oldest/longest target tracked (recommended)
3 = Average speed of the of the oldest/longest target tracked
Typical response – #MM?1
*MS
This command dictates how the radar reports targets over an RS422 connection. It offers a number
of speed message formats at varying Frames Per Second (fps), or one per detect state.
Note that ‘d’ represents a decimal digit and ‘x’, a Hex character:
0 none
1 DCFMSxx.xx 20 fps
2 dd 20 fps
