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.

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 7 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.

Description
(wrt Radar)
Input
Input
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.
Page 9 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.

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
Description
Configuration
Variable Name
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 11 of 17
MO
TA
KY
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)
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).
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.
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 12 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.

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 14 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 =). 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:  [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.)
 - 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:[ENTER]
e.g.
get:LO
returns
LO=5 (if value is presently set to 5).
