Page 5 of 13 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. This allows you to position the unit in a median without worry of picking up traffic on the outgoing lane For optimal performance, keep in mind the following: 9 Radar should be mounted with the circuit board 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 may pickup rotating fans. Avoid pointing it at fans or compressors. 9 Radar should be mounted at least 3+ feet high from the road for optimal performance. Hookup: Power Input: The DR-1500 radar can be powered from a nominal 12V DC battery and features industry leading operational power consumption. This is up to 10X lower than competing products. 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.
Page 6 of 13 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 standard RS232 serial port on a PC, message boards and speed displays. Log/Statistics Storage: The DR-1500 radar has capacity to store the last 60 days of traffic statistics in 5 minute bins and features a clock/calendar that retains time even when external power is removed. The clock is used to time stamp the collected statistics. This feature is an add-on software option. Please contact Houston Radar LLC for purchase of this option.
Page 7 of 13 Wire Signal Descriptions: The DR-1500 features an output that can wake up an external display panel(s) to bring it out of power saving mode when a vehicle is detected. If the panels you hook to the radar do not feature such an input, this wire should remain unconnected. If you use the Houston Radar LED display panels, tape off wire #’s 2,3 and 10. Connect the remainder wires to the similar # wires in the cable supplied with the panels. If you use other industry panels, tape off wires #3,4,6 and 10. You will only need to connect wire #2 to the RS232 input of the panel and wire #5 to the “ground” or –ve of the panel. Please consult the manual of the panel you are connecting to. USE Turn on the power to the DR-1500 to make it operational. No other action is required. The radar will output data over the serial port(s) whenever it detects a vehicle that is above the programmed lower speed limit and below the programmed high limit. The default limits are set at 5mph and 99mph at the factory. Using the IR remote control, program the high limit to blank out the speed display above this limit. This will prevent “racing against the radar” by denying a speed feedback display of excessive speeds as determined by you.

Page 8 of 13 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. Optional DR-1500 Remote Control
Page 9 of 13 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). Then execute the following steps to program the desired functions: Speed Low Limit: Use this feature to only give speed awareness feedback to vehicles over a certain limit, for example the road speed limit. This would setup the system to not display the speeds of vehicles that are below the limit, rather only display the speed of vehicles that are above the limit. With panels that support the “power saving mode”, this can result in very significant power savings and significantly extend operation time between battery recharges. 1. Press the “LOW LIMIT” key once [The current value will be displayed on the display] 2. Enter the numeric speed for the low limit (or use the Up/Down arrow keys) 3. Press “SET/OK” to save the limit in the radar or press “CANCEL” at any time before “SET/OK” to cancel this operation Speed High Limit: Use this feature to blank out the speed display of vehicles over this limit. You can use this feature to defeat “racing against the radar” issue. 1. Press the “HIGH LIMIT” key once [The current value will be displayed on the display] 2. Enter the numeric speed for the high limit (or use the Up/Down arrow keys) 3. Press “SET/OK” to save the limit in the radar or press “CANCEL” at any time before “SET/OK” to cancel this operation Speed Limit: Use this feature to flash the speed display of vehicles over this limit. You can use this feature to draw attention to the speed of vehicles going over the set limit. 1. Press the “SPEED LIMIT” key once [The current value will be displayed on the display] 2. Enter the numeric speed for the speed limit in effect at the current location 3. Press “SET/OK” to save the limit in the radar or press “CANCEL” at any time before “SET/OK” to cancel this operation
Page 10 of 13 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 the “SENSITIVITY” key on the remote once [The current value will be displayed on the display] 2. Enter the desired sensitivity as a two digit value from 10 to 99 percentage of maximum range of the radar or use the Up/Down arrow keys 3. Press “SET/OK” to save the limit in the radar or press “CANCEL” at any time before “SET/OK” to cancel this operation Internal Clock: Use this feature to set the internal clock of the radar. This is only required if you have purchased the optional statistics collection package. The unit will keep time even with external power removed. It may be more convenient to set the clock of the radar by connecting a serial cable to the radar and using the “Houston Radar Stats Analyzer” program. A button in the program allows you to sync the radar clock with your computer clock. However, the following steps may be used in the field to either check or set the time of the radar 1. Press the “CLOCK” key on the remote [The radar will display “SE”- short for seconds of the current time] 2. Press the “UP” arrow key on the display to move to the minutes option [The radar will display “MI”- short for minutes of the current time] 3. Press the “UP” arrow key on the display to move to the hours options [The radar will display “HO”- short for hours of the current time] 4. Press the “UP” arrow key on the display to move to the day of the month option [The radar will display “DA”- short for day of the current day of the month] 5. Press the “UP” arrow key on the display to move to the month option [The radar will display “MO”- short for month of the current date (January is “1”, December is “12”)] 6. Press the “UP” arrow key on the display to move to the month option [The radar will display “YE”- short for year of the current date (2000 is “00”, 2006 is “06” etc.)] To set any of the above value, navigate to the desired option, then press “SET/OK”. At this point the radar will display the current option. You may then directly enter the desired value for the option and press “SET/OK” again.
Page 11 of 13 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. Press 0 to display speed in MPH or 1 to display speed in KMPH 4. Press “SET/OK” key to save in memory. [Radar will restart and count up from 1 to 9 and the display will go blank. The unit is now ready] Reset Factor Settings: 1. Press the “F1” key on the remote [The radar will display “F1”] 2. Press the “3” key on the remote 3. Press the “SET/OK” [Radar will display “OK” and then restart and count up from 1 to 10 and the display will go blank. This will reset the baud rate to 115200, display units to MPH, low limit to 5mph, high limit to 99mph and speed limit to 99mph]. Set Serial Baud Rate: This configuration is only required at the factory when mating the radar to the selected speed digit display panels. Once configured, the radar keeps the configuration even after power is removed and need not be reconfigured. The optional statistics package can communicate with the PC to download saved statistics at any set baud rate. The baud rate of the radar is automatically detected by the stats package. Use this feature to set the baud rate of the serial data port by following the following steps:
Page 12 of 13 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. Your baud rate is now programmed in permanent memory and if you have speed display panels hooked up, they will display the two digit key combination that you entered to select the baud rate. If you want to change the baud rate of the radar, you can simply follow the above procedure and select a new baud rate any number of times.
