- Page 3 AGD332 INTRODUCTION Sign Activation Radar PRODUCT AND TECHNOLOGY The 332 detector is a true ranging FMCW radar designed for OEM integration into Vehicle Actuated Sign (VAS) applications. Operating in the 24GHz K-band, the 332 offers an accurate speed measurement while discriminating between advancing and receding traffic. Technical advancements allow for extremely low power consumption while maintaining vehicle detection distances up to 180 metres.
- Page 4 PRODUCT NO. DESCRIPTION 332-100-000 Sign Activation Radar/12V/24.2GHz/RS232 332-101-000 Sign Activation Radar/12V/24.125GHz/RS232 (FCC) PRODUCT OVERVIEW The 332 radar has taken the powerful feature rich experience from the low power AGD331. Using the latest power saving technology, the radar’s design is a unique pulsed, frequency modulated transceiver linked to a 32bit ARM Cortex M4 processor. This helps deliver market leading radar performance while maintaining extremely low power usage. Traditional Continuous Wave (CW) Doppler radars for sign driving applications have no ranging capability. The 332 contains filter-down technology from AGD enforcement products, this furnishes the radar with a full multi-target acquisition platform, accurate range measurement, and adjustable output rate of targets. To the VAS designer, this simply means the system power is more efficiently managed by the ability to select the area of interest accurately (regardless of vehicle size). Designed to be simple to use and quickly deployed with a variable sign solution, the 332 range and low speed can be set-up via an RS232 serial interface. AGD332 | SIGN ACTIVATION RADAR...
- Page 5 The front face of the radar should be vertical i.e. perpendicular to the road before you begin site specific adjustments. The relatively wide beam profile of the 332 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. The radars front face should be 90 0 to the road surface, inclines in the road surface should be catered for by adjusting the 332 radars mounting angle. AGD332 | SIGN ACTIVATION RADAR...
- Page 6 Targets that have a larger RCS will return a larger signal than those with a smaller RCS. For example: If the detection range is set at 80 metres then all targets that return enough reflective power before this point will be tracked. Only when the target reaches 80 metres will the detection be reported, allowing for accurate actuation of the sign at the correct range. Maximum Range 180m Dual Lane Detection 25m Minimum Range AGD332 | SIGN ACTIVATION RADAR...

- Page 8 Flow control (handshaking) None Transmit delay Communications can be established with the 332 Radar using CA-293 (FTDI USB-232 converter) cable assembly supplied separately. It should be connected as follows: FTDI Wire Colour 331 Terminal Connection Function Black, White or Green 0v / GND Brown Violet Please note: The board attached to CA-293 switches Tx and Rx functions ready for PC connectivity. If a different FTDI USB-232 converter cable is used you might have to switch Tx and Rx functions manually by swapping the violet/brown wires. AGD332 | SIGN ACTIVATION RADAR...
- Page 9 For example MUST DETECT *DIR=A<CR> Radar responds with #DIR=A<CR> ZONE *DIR?<CR> Radar responds with #DIR?A<CR> Communication Tasks The operation of the 332 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. Up to 10m Up to 10m Command requests to store settings are written to EEPROM each time they are sent from the host system, repeated sending of commands will erode the lifetime capacity of the radars non-volatile memory.

- Page 12 Example: *OUT1 = detect, 30, 50, 70, A<CR> Will set FET output 1 to detect targets between 30 and 50 (mph or kph depending on the value of *SU) up to a range of 70 metres when they are advancing towards the radar. Example: *OUT1=disabled<CR> Will disable FET output 1 from operation in RS232 mode. However, the output can still be set using SW1 and SW3. Example: *OUT2=count<CR> Will enable the count function on FET output 2 only, and will also provide a count data line in the RS232 output. AGD332 | SIGN ACTIVATION RADAR...

- Page 14 The range at which vehicles are counted in both advancing and receding directions has been carefully tested and calibrated and is a non adjustable value. The distance for advancing is 20 metres and the distance for receeding is 40 metres. FET 2 Digital Output FET 2 in count mode will only pulse ‘ON’ once per frame to represent a vehicle count, the length of the pulse allows the data to be extracted from the FET 2 output: 35ms ‘Pulse’ = 1 advancing target counted this frame 55ms ‘Pulse’ = 1 receding target counted this frame 75ms ‘Pulse’ = 1 advancing AND 1 receding target counted this frame Count Accuracy Free flow, moderate and heavy flow studies have returned an average accuracy of >93%. When the radar is operating in OM=LS mode looking at slow moving traffic, the accuracy will be reduced depending upon variables such as gaps between vehicles. AGD332 | SIGN ACTIVATION RADAR...

- Page 16 Why is the LED on the 332 flashing repeatedly or intermittently? The operational voltage supply range for the radar is 5.5 to 15Vdc (nominal 12Vdc). It is possible, especially in solar & battery based installations that the voltage supply level can fall outside the specified limits. Operation of the radar is not guaranteed outside these limits and incorrect operation can be manifest in an erratic or flashing LED state. Please check the voltage supply and reconnect the radar.

- Page 17 There is no requirement for the customer to return the hardware to AGD for upgrade. The sign has been EMC tested and the radar has a CE mark. If I put the radar on the sign will that be enough to legally put this on the market in the EU? This is not a safe assumption to make. There are special directives and associated specifications in the...
