This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harm-ful interference to radio communications. Operation of this equipment in a resi-dential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. Operation is subject to the following two conditions: 1. this device may not cause harmful interference, and 2. this device must accept any interference received, including interference that may cause undesired operation. Changes or modifications made to this equipment not expressly approved by JENOPTIK Robot GmbH may void the FCC authorization to operate this equip-ment.
RRS24F-SD/20 2 Product Information The RRS24F-SD2/20 is a K-Band RADAR sensor intended for the monitoring of vehicle speed in road traffic. Features of the sensor are: − Operates within the 24GHz ISM band. − Transmitter power < 20dBm e.i.r.p., R&TTE conform. − Continuous Wave (CW) transmission. − Peak power transmission at 20°l to the front face of the product (20° squint angle). − Horizontal beam width, within -3dB limits, of ±2,5°. − Vertical beam width, within -3dB limits, of ±10°. − Speed in km/h, vehicle duration in meter, distance to vehicle in deci-meter and vehicle direction for each measured vehicle. − Single cable for power and communication. − Communication using proprietary message protocol over standard ‘232 / ’422 serial interface. Typically the sensor is connected to an intelligent camera system that provides power and control. When activated the sensor sends a message to the camera in response to vehicles passing through its beam. Each message is analyzed in the camera and may trigger the recording of an evidence photograph. 2.1 RRS24F-SD2/20 Functional Description The RRS24F-SD2/20 includes all components necessary for traffic speed monitoring in a single robust waterproof enclosure. Using a simple propriety command protocol the sensor can be configured as required by the measure-ment location. Once activated, the internal CPU translates the complex Dop-pler signal at the output of the transceiver into verified values of vehicle speed, distance, duration and direction. All valid measurements are forwarded auto-matically to the host using the serial interface. Only a single connection cable is required. The sensor interface is optimized for use with an intelligent camera system from JENOPTIK Robot GmbH.

RRS24F-SD/20 Robot/590106/250610/En/A 6 K-Band Antenna and Transceiver IVS-157_V2_squint K-Band antenna and transceiver integrates the following parts: − Patch array structure with a constant beam form and direction. − K-Band transmitter with voltage controlled oscillator frequency. − Low noise receiver and quadrature mixer. − Dual base-band outputs of the recovered Doppler signal. The direction of maximum transmitter power is normal to the face of the sen-sor. Measured between points 3dB below peak power, the beam width is ±2,5° in the horizontal direction and ±10° in the vertical direction. All side-lobes measured in the horizontal direction are at least 20dB below peak transmitter power. The transmitter is active only when the sensor is placed in measurement mo-dus by the host (camera). ADC The dual outputs of the IVS-157_V2 are digitized at a fixed rate. The continu-ous stream of samples is passed directly to the CPU for processing. CPU The CPU searches the stream of samples from the ADC for moving vehicles. When recognized, its speed and distance are measured throughout its pas-sage through the Radar beam. On leaving, the acquired measurements are checked for quality and consistency, then corrected for the angle between ve-hicle motion and sensor direction (assumed to be 20°). The verified speed/distance measurement is packed together with the vehicle duration in the radar beam and its direction. This package is then sent directly to the camera via the serial interface. All speed and distance measurements are referenced to a quartz-stabilized clock. Serial Interface The serial interface operates in ‘232 or ‘422 modus, dependent on the connec-tion cable used. System Monitor All supply voltages and the sensor temperature are constantly monitored. Should any parameter move out of tolerance, the measurement modus is im-mediately terminated and the transmitter shut down. The sensor than waits for the fault to be resolved prior to restarting speed measurement. Power Supply The supply from the camera is converted and regulated to the various voltages required by the sensor. All voltages, including the input supply voltage, are constantly compared to upper and lower tolerances. Operation of the sensor is only possible when all supply voltages are within tolerance. 2.2 Technical Data RRS24F-SD2/20 Measuring range: 10 km/h to 300 km/h Measuring accuracy: 10 km/h to 100 km/h ± 1 km/h 100 km/h to 300 km/h ± 1%

Array Type: IVS-157_V2_squint Transmitter frequency: 24.1 GHz Transmitting power: 20dBm e.i.r.p. (R&TTE-conform) Weight: 2.2 kg Dimensions (W x H x D): 294 mm x 124 mm x 49 mm 3 Sensor Location There are several options available for assembly of the sensor at the meas-urement location. It is well suited to assembly on a tripod at the roadside; in a vehicle (moving or parked) or to assembly in a fixed radar enclosure. In all situations the following points are important for dependable and accurate measurement. − The sensor assumes that the vehicle to be measured is moving at an angle of 20° to the radar beam, and corrects the measured speed ap-propriately. This requires that the RRS24F-SD2/20 be mounted parallel to the direction of vehicle motion (i.e. road edge).

For this purpose a section of road can be considered straight when the shortest distance between a 35m long straight line and the road verge is not more than 0,1m (radius of band >1600m). Following assembly at the measurement location the interface cable from the intelligent camera is attached to the sensor and the measurement modus acti-vated using the camera GUI.
