(regardless of vehicle size). Designed to be simple to use and quickly deployed into the end users sign solution, the 331 range and low speed can be set-up and adjusted via rotary and dip switches conveniently located on the rear of the unit. Additional parameters are accessible via an RS232 serial interface. -

6.0mm 15mm +/- 1mm The relatively wide beam profile of the 331 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. The recommended mounting height of the radar within the sign is between 2-5 meters with the optimum being 3 metres. -

RADAR INSTALLATION - RANGE IN-SIGN RADAR TRAFFIC DETECTOR AGD 331 The 331 is a true ranging radar that allows the user to select at what range the radar needs to start reporting on IN-SIGN RADAR TRAFFIC DETECTOR tracked targets. AGD 331 Each target needs to return sufficient signal in order for the radar to track its range. -

Radar responds with #DIR?A<CR> Communication Tasks The operation of the 331 radar has been optimised as a low power device with minimal processing overhead. It is good practice to not ‘overrun’ the communication line with repeated send commands when the radar is operational. -

Radar Commands and Configuration AGD 331 RS232 OUTPUT MESSAGE IN-SIGN RADAR TRAFFIC DETECTOR AGD 331 The speed of a single target of interest can be reported using the RS232 connection. This is typically used to IN-SIGN RADAR TRAFFIC DETECTOR display the actual speed of a target as it approaches the sign. -

IN-SIGN RADAR TRAFFIC DETECTOR If you choose to configure the 331 using the physical switches, you would set the speed threshold you wish to report a target travelling over, using SW1. The range could then be set using SW3. This would set-up FET 1 (*OUT1) to actuate according to your set parameters. -

Dynamic frame rate is used to reduce the power consumption of the 331 whilst no valid targets are being IN-SIGN RADAR TRAFFIC DETECTOR detected. It does this by reducing the number of times the transmitter looks for a target per second, after the 331 AGD 331 has not detected a target for 1 second. -

AGD 331 which is of the order of the user range setting intervals. However, the 331 does have a feature to decease the frame rate (*DFR command). Dynamic frame rate reduces the power consumption of the 331 whilst no valid targets are being detected. - Page 20 ‘stealthy’ profile and the effect on detection range. I have mounted the 331 radar in the sign and set the detection distance to 60m but I am only getting a detection range of typically 30m which varies with each target? The radar is designed to operate through a plastic screen which normally forms the front face of the sign.
- Page 21 The target range measurement is treated in the same way as the speed measurement. My 331 has a different product number to the ones listed on page 4. What is the difference? The general operation and function are the same for new and old 331 radars. The 24.2GHz variant 331-100- 000 has been superseded by 331-102-000 and the 24.125GHz FCC variant 331-101-000 has been superseded...
