Page 6: Introduction
Advanced DSP based algorithm yields consistent performance and speed detection SS300U features 90+ m (300+ feet) of pickup distance for incoming vehicles on open and level road. SS300ULG is optimized for close up detection of large targets such as trains, conveyor belts and other industrial applications. -
Page 7: Direction Pointing
SS300ULG. Recommended Enclosure for the SS300U-OFD: The SS300U-OFD radar needs to be enclosed in a weatherproof enclosure for outside use. The following needs to be observed for optimal performance: 1. The front face of the radar (with the golden pads) is the antenna and is the face that must point into traffic. -

ON via a bit in the “MD” variable. Measured Speed Output: The SS300U will send out the measured speed via the ASCII interface as a 3 digit speed with an optional direction indicator. The format is: [?,+]nnn[.ddd][\r,\n]... - Page 10 All configuration variables may be accessed via simple ASCII interface. It is described in greater detail in our ASCII interface application note.

(0KPH). Green LED flashes at 1/3 Hz (12.5% duty cycle) rate when radar is running giving a visual OK signal. In the SS300U-OFD version green LED may be installed on the back depending on the requested build option. Page 12 of 22... -
Page 13: Configuring The Unit
Configuring the Unit: The unit’s internal parameters may be configured after connecting the radar’s RS232 port to a PC’s RS232 serial COM port and using the Houston Radar configuration program’s “Connect To Radar” screen as described here. The following internal “variables” may be set. Their functions are described below. - Page 14 Note 1: Bit 12 of the MO variable sets direction of detection. This functionality is available in firmware versions v115 and higher release date Jan 21 2010. Older radars may be upgraded to this version. Please contact Houston Radar for a firmware update. The following variables are available in the SS300ULG only. SS300ULG...
- Page 15 Houston Radar SS300U User Manual Output decimation value in number of measurement cycles. For example, one cycle is 81ms with range 0 (see Table 1). So a value of 1 will output a new speed value every 81ms. A value of 5 will output a new speed every 5 cycle or every 0.405 seconds.

Houston Radar SS300U User Manual Setting Variables in the Radar: 1. Install the provided Houston Radar Advanced Stats Analyzer (or Houston Radar Configuration) Windows program on a Windows 2000, XP, Vista or Win 7 computer. 32 and 64 bit computers are supported. - Page 17 Houston Radar SS300U User Manual 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.
