INTRODUCTION Congratulations on your purchase of the Houston Radar LLC’s directional Doppler speed radar DR-1500. 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.
INSTALLATION Mounting: The DR-1500 is supplied with a mounting plate and may be conveniently mounted via 4 mounting holes inside your enclosure. Use a “split washer” is used to ensure the mounting screw remains tight under vibration. Direction Pointing: The DR-1500 is directional in nature. It rejects traffic moving away from it and only measures oncoming traffic. If the optional stats analyzer feature is purchased with the unit, stats will only be collected for incoming traffic.
Serial Connection: The DR-1500 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 (or Kmph if set via the remote) as three ASCII digits in the following format: nnn\n\r where: nnn : The three digit ASCIII speed digits in mph/Kmph \n\r : A new line followed by a carriage return character This format is compatible with other industry formats including a standa

Required only if connected to PC to download stats from unit RS485 “+” terminal. 5 6 7 GND RS 485 Panel Power Save Input I/O Output System Ground. Connect to battery RS485 “-” terminal. See Note 1.
Infrared Remote Programming: The DR-1500 operational parameters may be accessed and programmed in the field using an optional infrared remote control. These features may only be programmed in conjunction with speed display panels that support visual feedback of ASCII chars sent on the serial data line. Contact the factory for availability and a list of panels that support this feature. However, the Houston Radar LED panels do support this feature.
This section describes these features and how to program the values into the radar using the IR remote. Apply +12 V DC battery power to the radar power wires. Stand in front of the radar, between 2 and 10 feet away and point the IR remote at the front face of the radar (the IR receiver window is the small circular hole below the rectangular window).
Detection Sensitivity: Use this feature to set the detection sensitivity. This affect the distance the radar detects objects. You may set the sensitivity from a value of “10” to “99”. Each value is an approximate percentage of maximum detectable range (typically 500 to 600 feet for the DR-1500). Setting the value to “99” sets the range to maximum. This is due to typically only two display digits being used with the radar. 1.
Press “CANCEL” to at any time or after the final “SET/OK” to exit the menu. Self Test: Press the “SELF TEST” key on the remote to instruct the radar to perform a self test. The radar will display “OK” after about 6 seconds if the test passes. It will then reset and count up from 1 to 9 and then the display will blank out. Display Units (MPH or KMPH): 1. Press the “F1” key on the remote [The radar will display “F1”] 2. Press the “4” key [The radar will display the current value code. 0 = MPH, 1 = KMPH] 3.
Select the baud rate from the table below and note the key combination from the “Key #” column in the table. Press the “Set Baud “ key on the IR remote followed by the two digit numeric code from the desired baud rate row picked in #3 above, followed by the “Select” key. You may press cancel any time in the above procedure to cancel programming the new baud rate. The new baud rate is not stored and changed till you press the “Select” key.
