- Page 3 Safety Critical Application Notice: Warning: The DC310 radar is not a fail-safe device. It should not be used in any application where failure or non-performance of the device will result in a hazardous condition. If used in a “wrong way” application to detect vehicles traveling in the wrong direction on the road, it must not be relied upon to provide 100% performance in all conditions.

Page 5: Introduction
INTRODUCTION Congratulations on your purchase of the Houston Radar directional Tracking Doppler Radar DC310. This state of the art 24GHz K-band microwave Doppler radar is specifically designed for the license free battery operated traffic monitoring, data collection and “wrong way” vehicle detection market. -
Page 6: Installation
Mount in the median of a four lane divided road to measure both directions. Pick a location where the median is no more than 12 (3.6m) feet wide. Mounting on the side of a 4 lane divided road will allow the DC310 to capture only the closest two incoming lanes accurately. -
Page 7: Recommended Enclosure For The Dc310-Ofd
Recommended Enclosure for the DC310-OFD: The DC310-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. Average Speed Output: The DC310 can send out the average measured speed via the ASCII interface as a 3 digit speed with a direction indicator. This option is turned off in the default configuration and must be enabled if desired. -
Page 9: Speed Output Event
Speed Output Event The DC310 can send out individually logged vehicle speeds via the ASCII interface as a 3 digit speed with a direction indicator. This option is turned off in the default configuration and must be enabled if desired.

The radar will activate the appropriate OUT 1 and OUT 2 open drain outputs, if enabled, whenever the selected detection trigger condition is satisfied by a vehicle that is above the programmed lower speed limit (the “LO”... -
Page 14: Internal Clock
The radar’s internal parameters may be configured via the radar’s RS232 port after connecting to a PC’s RS232 serial COM port and using the Houston Radar configuration program’s Graphical User Interface (GUI). While this is the most convenient way to configure the radar, customers may also wish to set the configuration variables directly, for example when the radar is part of a system and connected to another microcontroller. - Page 15 Houston Radar DC310 User Manual Bit 10 to 15: Currently reserved in DC310 radar Radar mode bitmask number 2. Bits are as follows: Bit 0: Enable low voltage power down. See Appendix C for details. Bit 1: Enable True Average Speed output Bit 2: Force enable the RS232 interface when set.
- Page 16 Houston Radar DC310 User Manual trigger is materially higher than trigger from logged vehicle. However, if you need an indication that the radar is tracking a vehicle before it passes you may use this trigger mode. For example this may be used to wake up attached equipment or display a local warning in a “Wrong...

Page 20: Step 3: Select The Radar Units
Houston Radar DC310 User Manual STEP 3: Select the radar units Radar units apply to the speed output over the RS232 serial port as well the low limit cutoff and high limit cutoff settings. Additionally, if traffic statistics gathering is enabled, statistics are saved in integer mph boundary speed bins for mph and ft/sec units and in km/h integer boundary speed bins for km/h or m/s units in the radar. -
Page 21: Step 4: Set The Radar Cutoff Speeds (Low And High Speed Cutoff)
Cutoff speeds affect the measurement range for sending speed out over the serial port and activation of the hardware trigger outputs. Cutoff speeds will affect collection of traffic statistics for the DC310. Traffic statistics will not collected outside of the detection limits. -

At least 100 feet of visible travel distance must be allowed before the DC310 radar will flag the wrong way vehicle. A rear facing SS300 radar is mounted behind the DC310 radar. In this setup, the SS300 will be facing the back of the wrong way vehicle as it recedes from the radar after passing it. - Page 30 Houston Radar DC310 User Manual If a local warning light is required, the 2 output on the DC310 radar may be configured to trigger on an incoming vehicle and connected to trigger a flasher or local lights to draw attention to the driver of the wrong way vehicle. This trigger should not be used to initiate a call as the false trigger rate on this output will be higher than “trigger on logged...
