INTRODUCTION Congratulations on your purchase of the Houston Radar LLC’s directional Doppler speed sensor SS300. This state of the art K-band microwave Doppler speed radar based sensor is specifically designed for the license free battery operated speed-sensing market. 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.
Direction Pointing: The SS00 is directional in nature. It rejects traffic moving away from it and only measures oncoming traffic. If you require the unit to detect outgoing traffic, please contact Houston Radar for a firmware update. For optimal performance: Radar should be mounted with the words “NARROW” on the face of the unit either on the top or bottom Radar should be pointed into the direction of the oncoming traffic.
Hookup: Power Input: The SS300 radar should be powered from a nominal 12V DC battery and features industry leading operational power consumption of less than 9mA (average). There is no other radar in the world that even comes close to this ultra-low power usage. This operational power translates directly into a longer battery life or gives you an option to power the unit from smaller batteries that would also require smaller solar panels.
Note 2: A reset is required after setting the sensitivity as the radar will no longer send speeds out (it changes the mode to a different serial interface mode). The regular interface mode is restored when the radar is powered cycled. No reset is required when using the Windows PC interface.

See Note 1. 8 Trig O/P 2 Output “Open Drain Output 2”. See Note 1.
USE Turn on the power to the SS300 to make it operational. No other action is required. The radar will trigger OUT 1 and OUT 2 open collector outputs whenever it detects a vehicle that is above the programmed lower speed limit (the “LO” value) and below the programmed high limit (the “HI” value). The default limits are set at 5mph (kph) and 99mph (kph) at the factory (the values in brackets apply if units are set to KPH).
Internal Clock: The radar has a built in clock/calendar function. At the moment this is not used by the firmware. However future functionality may be added that uses this functionality. The radar does not feature a clock backup battery. So power must remain connected to the radar for the clock to keep time.
Setting Variables in the Radar: 1. Install the Houston Radar Advanced Stats Analyzer Windows program on a Windows 2000, XP or Vista computer. 2. Connect the radar RS232 port to the PC’s RS232 serial port. If the PC does not have a serial port you may buy a USB serial converter dongle (from BestBuy, Radioshack or any Internet store). 3. Power up the radar. Ensure the green LED on the front flashes at a 1/3Hz 1/6 duty cycle rate. 4. Start the Houston Radar Stats Analyzer program 5.
Set Serial Baud Rate: The supplied Windows configuration program can auto detect the baud rate of the radar serial port. However if you wish to communicate with the radar from your electronics, the radar serial port may be configured to different baud rates.

Appendix A: Hooking up to the trigger outputs on the radar The SS300 radar features two “open drain” outputs. The device used for this purpose is the On Semiconductor relay driver NUD3160. The output configuration of this device is shown below (from the On Semi datasheet). The two outputs O/P1 and O/P2 are brought out on the radar connector pins (see IO connector pin out in manual for connector pin numbers).
