This state of the art K-band microwave Doppler speed radar is specifically designed for the license free, battery operated speed radar market, for use in speed awareness trailers, school zones and other speed restricted traffic zone speed awareness uses. Utilizing the latest in high performance, ultra low power DSP (Digital Signal Processing) technology, you will find that this high quality product meets your exacting standards for performance and reliability. Some of the highlights of this product include: 9 FCC approved for your convenience and piece of mind 9 Advanced DSP based performance yields consistent performance and speed detection 9 Standard serial port hookup and data format allows hassle free use in existing systems o Use in place of existing products o Interface to your message displays o Use in your speed trailers o Use in school zones 9 Up to 5X lower operational power consumption vs. competing solutions allows use of smaller batteries and solar panels- saving you cost 9 Rugged weatherproof enclosure features side mounts and short depth 9 Built in clock/calendar allows pre-programmed times of operation 9 Only 50 micro amps power consumption in standby mode 9 Optional infrared remote control allows you to change/set: o Min/Max speed limit of detection o Internal clock/calendar and operational times o Serial port settings INSTALLATION Mounting: The DR-500 is supplied in a weatherproof enclosure and may be conveniently mounted via the side-mounting bosses, outside the speed trailer enclosure to facilitate pointing it into the oncoming traffic. Two #8-10 size screws are required for side boss mounting (provided). Care must be take to ensure that the provided “split washer” is used to ensure the mounting screw remains tight under vibration. Direction Pointing: The DR-500 is directional in nature. It rejects traffic moving away from it and only measures oncoming traffic. For optimal performance, keep in mind the following: 9 Radar should be mounted with the mounting bosses horizontal to the road. 9 Radar should be pointed into the direction of the oncoming traffic. 9 Radar should be placed along the size of the road to minimize the angle of the oncoming traffic to the radar. o If radar cannot be placed right along the side of the road, it should be pointed at least 200-300 feet up the road into oncoming traffic. 9 The radar will pickup rotating fans. Avoid pointing it at fans or compressors. 9 Radar should be mounted at least 3 feet off the road for optimal performance. Hookup: Power Input : The DR-500 radar is designed to be powered from a nominal 12V DC battery and features industry leading operational power consumption, which can be as low as 5X less than other similar radar designs on the market. This operational power translates directly into a longer battery life or gives you an option to power the unit from smaller batteries which would also require smaller solar panels for charging resulting in material cost savings in an entire solar charged battery operated speed awareness trailer. Serial Connection : The DR-500 features a dual RS232 and RS485 output that are active at the same time giving the user an option to connect serial outputs to either port (see serial port diagram). Speed data is output serially in mph as three ASCII digits in the following format: nnn\n\r where: nnn : The three digit ASCIII speed digits in mph \n\r : A new line followed by a carriage return character This format is compatible with other industry formats including a standard RS232 serial port on a PC, message boards and speed displays. Log/Statistics Storage : The DR-500 radar has capacity to store up to 4Mb of traffic statistics and feature…

As such, the device is more adequately defined as an end product. As such the device would receive its own FCC ID number (as shown by placing the ID on the case), but it would not be necessary to apply the modular approval route. A modular approval for this device would place the FCC ID on the transmitter board/module itself. 4. Please note that the 731 form states the device operates under 15.245 but the test report states the device was tested to 15.231(e). Please explain and please be consistent in all documentation. Please correct all documentation as needed. 5. Please note that the test report states the operating frequency is 418MHz, but other documentation (i.e. operational description, 731, manual etc) states the device operates in the 24GHz range. Please explain and please provide consistent documentation. Please correct all documentation as needed and please provide a report that is in accordance with the frequency, limits and rule part for the device. 6. Please note that the test report states that the antenna was ‘ Shortened the antenna element to a length of 12 cm”. Please note that the operational description states the operating antenna is a horn. Please explain. 7. Please note that the operational description states that the device is a Doppler radar. The bandwidth plots do not appear to indicate this type device. Please explain. 8. Please note that the Block diagram shows that the device operates on two available channels.

The undersigned is responsible for ensuring that Houston Radar, LLC., DR500 Doppler Radar will continue to comply with the FCC rules. Certificate Of Compliance Professional Testing (EMI), Inc. Project 05232-10 Page 4 of 13 1.0 EUT Description The DR-500 is a Doppler speed radar is powered by 12V DC nominal voltage. The microwave Gunn oscillator in the transceiver generates a 24.14GHz signal and sends it continuously out of the horn antenna at the target. The signal also "illuminates" internal (to the microwave transceiver) mixer diodes that act as a receiver mixer. The transmitted radar waves are reflected off the moving target, change the reflected microwave frequency per the well-known "Doppler principle" and are received by the same transmitting horn antenna and mixed in the receiving mixer diodes with the local oscillator. The difference in the transmitted/received frequencies is produced as a low frequency (audio frequency range) out of the mixer diode and into the preamp. The system tested consisted of the following: Manufacturer & Model FCC Number Description Houston Radar, LLC., DR500 TIADR500 Doppler Radar 1.1 Applicable Documents Guidelines FCC Rule Parts Part 15 Transmitter Characteristics 15.245 Spurious Radiated Power 15.205, 15.209, 15.245 Antenna Requirement 15.203 1.2 EUT Operation The EUT was operated in continuous transmit mode at max power to measure fu…
