Important Opto Variants AGD 318 TRAFFIC CONTROL RADAR OVERVIEW AGD 318 Available as simple single opto output or as dual opto output with added functionality. TRAFFIC CONTROL RADAR POWER & CONNECTIONS - 12VDC/24VAC/DC - SINGLE OPTO OUTPUT 12Vdc/24Vac/dc - Bulgin connector or 5m flying lead The output is an SPCO (SPDT) Opto with the impedance state of the relay being the same for a detect state or power off condition.
The detector is supplied with two 5m flying leads. One is the power supply for the detector and the other is the signal output and the correct cables should be identified before connection. The 318 is classified as a double insulated product and therefore the supply cable is two core (live/neutral).
Installation AGD 318 TRAFFIC CONTROL RADAR MOUNTING HEIGHT, ANGLES, CLEARANCE AGD 318 Mount the radar on a firm structure within a recommended height range of 2m-5m. For optimum performance TRAFFIC CONTROL RADAR the radar should be situated on a pole adjacent to the carriageway with an unobstructed view of advancing traffic.
2) Launch the software from your Desktop/Start menu by clicking the 318 Livewire icon. - The application will search for all 318 detectors within range and will display these once discovered 3) Select the desired 318 unit from the list and click continue.

Communications can be established to the Serial Comms version TRAFFIC CONTROL RADAR of the AGD 318 Radar by using the CA-250 cable assembly or a third party USB to RS422 Converter. A UART interface is provided that uses RS422 voltage levels on the communications connector.
System Integration The 318 has been designed to output a target message stream when a target is detected by the radar. When there is no target only the heartbeat message will be sent (if turned on). The radar is designed to send data and not make decisions on incidents that may be specified.
Firmware Functionality AGD 318 TRAFFIC CONTROL RADAR OVERVIEW (SERIAL COMMS VERSION ILLUSTRATED) AGD 318 At power-on the radar executes a Boot-loader program which communicates at a fixed Baud rate of 115200, no TRAFFIC CONTROL RADAR parity, 8 data bits and 1 stop bit over the RS422 interface. The Boot-loader provides facilities for erasing the Flash and updating the firmware.
TRAFFIC CONTROL RADAR A series of radar techniques have been used in the 318 to maximise the signal to noise ratio for a given target. The range performance of the 318 is tested at manufacture by simulation to ensure operation over the range 6 to 70m.
Radar Commands - Serial Comms Unit Only AGD 318 TRAFFIC CONTROL RADAR RADAR COMMAND OVERVIEW AGD 318 Commands are used to control the operation of the radar. These are sent over the RS422 UART link. TRAFFIC CONTROL RADAR Commands are immediately followed by an operator that indicates the required action. Not all operators are supported for all commands.
