Command Guide 1.0 Purpose The G-2 Vehicle detection module is a self contained Doppler radar sensor designed for the purpose of detecting and counting vehicle passages with speed and length data supplied. Suitable applications are traffic logging systems and speed enforcement systems. The system consists of a Gunn oscillator driven autodyne detected Doppler system with a single horn lens antenna with a 4X15 degree response pattern suitable for use in ATR traffic radar applications calibrated for a 22.5 degree traffic offset angle. Base band signals from the transceiver are amplified and processed with digital logic to produce a track for each dominant Doppler return received. Tracks are analyzed for consistency duration and frequency offset to create an individual output for each track, listing its speed, duration and overall reading quality. Output and control are provided via an ASCII coded serial interface provided with a full duplex rs485 or RS232 interface, for connection to external computing of logging equipment. 2.0 General Specifications Frequency 34.6 GHz +-100MHz Transmitter power level -8dBm Antenna Horn-Lens 30dBi gain Supply voltage – current -connector 10.5-14.8 VDC 750mA max Output ASCII serial 115.2k Baud RS232/DB9 or RS485/RJ-11 Mechanical Rectangular chassis 8"x3"x10"deep 4x6-32 mounting screws Microwave port 6.25"x2.75" 3.0 Installation 3.1 General Recommendations Unit should be installed with antenna level horizontally, tilted down to meet the roadway midway down its measurement range and at an offset angle of 22.5 degrees from the direction of traffic flow. Unit should be 5-10 feet from the nearest lane. The sensor should be placed far enough from intersections that vehicles traveling in other directions should not cross into the beam. The microwave port can be covered by an approved microwave transparent window. 3.2 Exposure Cautions Operating and maintenance personnel should maintain a separation of at least 20 cm from the port. Mounting should also preclude exposure to pedestrians or drivers. 3.3 Co-Location Warnings Additional radiators should not be co-located with the microwave aperture. 3.4 FCC Statement This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. Changes or modifications not expressly approved by Mesa Engineering could void the user’s authority to operate this equipment. 3.5 Field Tune Recommended field tune command sequence. This command is performed with a microwave absorbing foam block securely in front of the antenna horn. The Sequence adjusts the detector threshold for a background noise trigger rate dependant on the sensitivity threshold setting. Larger sensitivity settings have high noise trigger rates, hence higher signal sensitivity. Alignment should be performed anytime the sensor environment is changed, like switching vehicles or reinstalling a fixed unit. For directions on sending commands, see Command Guide section below. TN02 -- set sensitivity threshold to 2 TA Threshold -> 02 -- Auto tune thresholds ........ 04/0000/F7 ........ 03/0000/FA ........ 02/0002/FB ........ 01/0000/FC 4.0 Calibration Unit operating frequency should be certified at least once per year and electronic tuning fork test can be performed on starting and ending each deployment. 5.0 Interface Power Molex 39-01-4031 Pin: 1 3 GND +12 Data 115.2 kBaud 8 bit, no parity, no handshake RS232 9 Pin Sub-D Female Pin: 2 3 5 Out In GND RS485 RJ-11 Pin: 1 2 3 4 5 6 GND IN+ IN- Out- Out+ NC 6.0 Data Format 6.1 Power Up Message Alignment ch4 -> ch1 => F7 FA FB FC ATR g3 v3.0 FPGA revision 97 D9 1C The power up message provides the current field tune alignment, firmware revision level and the fpga revision level 6.2 Measurement Message The measurement message is a 30 byte message followed by an optional variable flag message terminated by cr-lf.
