Page 6 of 17 INSTALLATION Mounting: The DR600S is supplied in a weatherproof enclosure and may be conveniently mounted via the side-mounting bosses, outside the speed trailer enclosure to facilitate pointing it into the oncoming traffic. Two #8-32 size screws are provided for side boss mounting. The DR600C is provided in an open frame format with 4x corner holes on the PCB for mounting. Please request an outline drawing from Houston Radar for mounting details. If a battery is installed in the radar, you must ensure that this Lithium backup battery does not short to the frame or battery ground. Direction Pointing: The DR-500 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: ✓ Radar should be mounted with the mounting bosses horizontal to the road. ✓ Radar should be pointed into the direction of the oncoming traffic. ✓ 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. ✓ The radar may pickup rotating fans. Avoid pointing it at fans or compressors. ✓ Radar should be mounted at least 3 feet high from the road for optimal performance and at least 5 feet off the ground for pickup distance of 1500+ feet.
Page 7 of 17 Hookup: Power Input: The DR600 radar should be powered from a nominal 12V DC battery and features industry leading nominal operational power consumption of less than 16mA. This is up to 4X 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. Serial Connection: The DR600 has a standard 3 wire (RX, TX and Ground) RS232 port to output speeds and accept configuration settings. Speed data is output serially in mph (or Kph if set via the remote) as three ASCII digits in the following format: nnn\r\n where: nnn : The three digit ASCIII speed digits in mph/kph \r\n : A new line followed by a carriage return character When no further vehicles are detected, the radar outputs: 000\r\n or ?000\r\n (once or repeating depending on configuration) This format is compatible with other industry formats including a standard RS232 serial port on a PC, message boards and speed displays. Note: Optionally, the radar may be set to output the display speed in +nnn\r format. Please see serial port config settings table later section. Setting Detection Sensitivity via the ASCII Interface: In addition through the optional IR interface, the radar also allows programmatic sensitivity setting (and many other parameters in an industry compatible manner- contact us for details). Over the serial interface, send in ASCII the following commands: Sensitivity:nn\n and Sensitivity?\n In the 1st case it sets the detection sensitivity to "nn" where nn is from 10 to 99 and is a %
Page 8 of 17 of the max detection distance (typically about 1500 feet but can vary with installation effects and size of the target). If the sensitivity is set ok, it replies with OK\n Log/Statistics Storage: The DR600 radar has capacity to store traffic statistics in user programmable time bin intervals (default is 5 minute bins which yields 60 days of storage) and features a clock/calendar that retains time even when external power is removed. The clock is used to time stamp the collected statistics. Stats are stored in mph or kph units. This depends on the display units of the stats. See the IR remote programming section to change the display units of the radar. This feature is an add-on software option. Please contact Houston Radar LLC for purchase of this option. Detecting traffic statistics inside the radar has tremendous advantages: ➢ Radar tracks multiple vehicles at different speeds simultaneously and hence does not miss vehicles visible to it ➢ Radar access to all return signal parameters of the target vehicles processed by proprietary software inside radar makes full use of every bit of information present in reflected signal and dramatically improves counting accuracy ➢ No add-on boards keeps total system power usage down and reliability up ➢ Advanced Statistics are software “key enabled” allowing turn-on in the field or after the radars have shipped to the sign manufacturer ➢ Easy Bluetooth wireless access using standard Bluetooth modules you buy from your source or optional on board Bluetooth. Now enable statistics collection wirelessly! Please see a white paper on this topic on our web site for further discussion on this topic including some actual field test results.

Page 9 of 17 Wire Signal Descriptions: Note 1: The DR600 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 above a user set threshold. If the panels you hook to the radar do not feature such an input, this wire should remain unconnected. Normally this pin is pulled up to +12VDC by ~18KOhm resistor. When a vehicle is detected, this pin is pulled down to GND and held down to GND as long as a vehicle is detected. This pin is released to +12VDC as soon as the radar detects no further traffic. You must ensure that no more than 500 mA of current flows into this terminal when it is pulled low. DB9 Pin # Signal Name Direction (wrt Radar) Description 1 +12V DC Input Radar + Power Supply.

Page 10 of 17 USE Turn on the power to the DR600 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 (kph) and 99mph (kph) at the factory (but may be different for a particular user. Please consult the factory test report that is included with the radar). Using the serial interface, 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. On initial power up, the radar counts up from 000 to 010 to provide a quite visual check that it is operational. Collecting and Analyzing In-Radar Traffic Statistics The DR600 Radar supports optional “In-Radar” advanced traffic statistics collection. This feature is sold separately. If you radar has this feature enabled you may collect the stored statistics by using the provided Houston Radar Advanced Statistics Analyzer Windows program. This program must be installed on a MS Windows 2000, XP or Vista PC and allows the retrieval of stored statistics from the radar by using a PC serial port. It also has features to generate traffic reports, plot interactive graphs and export the raw data to a MS Excel file. Please refer to the on line help functionality of the program after you install it on your computer for detailed instructions on how to use its functionality. Real Time Traffic Statistics In the Radar: The DR600 In-Radar stats software now features “real time” histogram statistics. These are updated as soon as a vehicle is detected and may be read out as a speed bin count “histogram”. Thus no historical records need be read out and parsed to read statistics. This feature requires a host program to be on-line to read the live statistics. Please contact Houston Radar for more information if you are interested in acquiring live statistics from the radar.
Page 11 of 17 CONFIGURING THE RADAR Setting the following internal parameters configures the DR600 radar. All parameters are 16 bits wide (two bytes) and can accept values from 0 to 65535 (although not all possible values are valid for the all parameters). The unit’s internal parameters are configured via the radar’s RS232 port connected to a PC’s RS232 serial port and using the Houston Radar Advanced Stats Analyzer program’s configuration screen as described here. Alternatively, you may use the provided Houston Radar Configuration tool. The following internal “variables” may be set. Their functions are described below: Radar Configuration Variable Name Description RS Sets the primary RS232 serial port’s baud rate and speed output format. Do not change this value unless you understand the implications. RA Sets the auxiliary RS232 serial port’s baud rate. The output format is the same as the primary serial port (set by the RS variable above). UN Lower Byte: Sets the internal speed units of the radar. All LO, SP, HI, SI speeds are interpreted to be in this units. 0 = MPH 2=FPS (Feet per second) 1 = KPH 3=MPS (Meters per second) Upper Byte: Sets number of digits after decimal point. See note 1. LO Low speed cutoff. Vehicle speeds are not output below this speed. You may set this to 0, but the radar will only measure and output speed based on its minimum speed specification. Should value be set to be less than HI. HI High-speed cutoff. Vehicles speeds are not output above this speed. Should be set higher than LO speed. SP ‘Flashing’ speed limit. Any speed higher than this value ‘flashes’ the ASCII output at 2/3 duty cycle, 1Hz. Sending out 000 between nnn speed values interrupts the speed output to signal “flashing”. The trigger output is NOT de-asserted during flashing. It is up to the device connected to the radar to interpret this as ‘flashing’ and take appropriate action to flash the display. Set this to a value higher than HI to disable this feature. ST Target detection sensitivity. Valid values are from 10 to 99 and are a percentage of max range. So a value of 50 would yield about 750 feet detection. Note: This is not range setting but detection sensitivity. Thus if large vehicles are being detected at 2000 feet, a value of 50 will make them detect at approx 1000 feet etc. SF 1 = Select Fastest Target for speed output 0 = Select Strongest Target for speed output BN Set from 1 to 60 minutes of binning interval for stats collection.
Page 12 of 17 Traffic data binned (see below) and is accumulated for this duration in the bins and then a time stamped record made in stats memory in the radar. Speed bins are factory set and cannot be changed. They are: 5 MPH bins for MPH units (20 bins in total from 0 to 105 MPH) 10 KPH bins for KPH units (17 in total from 0 to 170 KPH) MO Radar mode bit mask. The bits controls different functionality as described below: Bit set (1) = enable functionality. Clear (0) = disable functionality, unless otherwise noted. Bit 0: SI3 compatibility mode for ASCII command to set and read sensitivity. Contact us for more details. Bit 1: ASCII output on primary serial port Bit 2: ASCII output on auxiliary serial port Bit 3 – 4: Reserved. Do not set. Bit 5: Fast updates. Sends ~8 updates/sec when enabled. DO NOT SET if using True Average Speed or In-Radar traffic stats else stats functionality will be adversely affected. Bit 6 – 9: Reserved. Do not set. Bit 10: Extra filtering for slow (<20mph) targets. Increases the internal validation time for slow targets before they are accepted as valid. Enable this bit if radar is seeing some fleeting spurious speed output below 20 mph (32 kph). (See note 2). Bit 11: “True Average Speed” mode. Requires purchase of in-radar traffic statistics collection option. Radar will send out average speed of all detected traffic over period set in TA variable. (See note 3). Bit 12: Outgoing detection. When set, radar will reject incoming targets and only report speeds of outgoing targets. (See note 4). Bit 13: Tuning fork mode. When set, disables directional selectivity for 30 seconds after power up. This allows the radar to pickup and display speed associated with tuning forks much easier than when in direction selective mode. (See note #5). TA Average Speed time period in seconds. If “True Average Speed” mode bit is set in the MO variable and in-radar traffic stats option is enabled, radar enters true average speed mode. In this mode, radar accurately averages the count-weighted speed of all targets and sends the average out on the serial port. It no longer outputs real-time speed of targets. KY Reserved. Do not set unless value provided by Houston Radar. Some features described above (and identified with a “see note”) were implemented in later firmware versions of the radar. The radar firmware may be updated in the field via the serial port. If you wish to use a feature not implemented in your firmware version, please request an updated firmware from Houston Radar by contacting us at contact@houston-radar.com.
Page 13 of 17 The firmware in the radar is displayed with the “VER=” tag when connecting to the radar via the Windows software provided with the radar. Alternatively, it may be queried via the “info” command via a command line terminal program like Hyperterminal or “Teraterm Pro”. It is also printed on the factory test report that accompanies all radars. Note 1: Decimal output and ft/s and m/s units requires firmware version #416 and later. Note 2: Extra filtering for slow targets requires firmware version #411 and later. Note 3: True average speed requires firmware version #424 and later. It also requires the optional “In-Radar traffic statistics” feature to be purchased and enabled. This may be done via software “key” set via the serial port in the field. Note 4: Outgoing detection feature requires firmware version #422 and later. Note 5: Tuning fork mode requires firmware version #427 and later.
Page 14 of 17 Setting Configuration Variables in the Radar: Setting variables via the provided Windows Graphical User Interface program: 1. Install the provide Houston Radar Advanced Stats Analyzer Windows program on a Windows 2000, XP or Vista computer. Alternatively you may use the provided Houston Radar Configuration tool. 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 from an external power supply or alternatively use the USB to serial port and power adapter available from us (our part #: 900-0016). 4. Start the Houston Radar Stats Analyzer program on the computer (Start->All Programs->Houston Radar->Houston Radar Stats Analyzer) 5. In the program window, click on Start->Connect to Radar… 6. Click on “Connect” button. 7. Ensure you see a “Radar found on COM” message. The COM # will depend on your computer . 8. Click on OK. Now you are ready to configure the radar. 9. To configure the LO, SP & HI limits, click on “Radar Limits” menu bar item. The three fields show the current values of the three variables. Change the variables to the desired values and click on “Save”. 10. To configure any other variable, click on “Advanced->Radar Configuration”. In the window that comes up, enter the two letter variable name in the “Variable” field (from the table on previous page). Enter its value in the “Value” field and click on “Set Variable” button.
Page 15 of 17 Setting variables from an ASCII Terminal program via ASCII commands: Starting from firmware version #415 all the radar variables can also be set and queried via a simple ASCII command set over the serial port. ASCII commands may be issued via an ASCII terminal program like Hyperterminal or Teraterm Pro. Alternatively, you may issue these commands from an attached microcontroller. The ASCII commands are: get (to get a config variable) set (set set a config variable to a supplied value) reset (resets the radar. Required after changing variables MO, MD and RS, RA(for DR series radars only). LO, HI, SP, ST, SF, UN do not require a reset). info (print out some info about the radar. Info is in the format of <tag>=<value>). New tags may be added in the future. Order of tags may be moved around. e.g. To set a variable (variables are documented in the user manual): set: <case sensitive var name> <value>[Enter] e.g. set:LO 5 alt format: set:LO=5 sets the low speed cutoff to 5 etc. Variables are case sensitive. Commands are not. Success is indicated by an "OK". Failure is indicated by either: "ERROR" - Command was recognized but some other error occurred (variable not present, format not correct etc.) <nothing returned> - Command was not recognized. Entire line was silently discarded. This ensures that spurious things like enters or other ASCII chars do not generate "ERROR" when you are not expecting them. To get a variable: get:<case sensitive var name>[ENTER] e.g. get:LO returns LO=5 (if value is presently set to 5).
