INSTALLATION
Mounting:
DR600-OFD is supplied in an “open frame” format. It requires a weatherproof enclosure
before it may be used outdoors. Alternatively it may be mounted as a component in
another product that already has a weatherproof enclosure.
The DR600-OFD should be mounted such that the connector points left or right
(Horizontally).
The DR600-DFT is supplied in a weatherproof encapsulated enclosure with a pigtail
connection. This unit may be mounted outside without any further protection from the
environment. The DR600-DFT should be mounted such that the cable gland is positioned
down and the mounting bosses are horizontal.

Page 6 of 35
Rotating the unit by 90 degrees from the suggested optimal mounting is not
recommended, and doing so will cause detection range to be significantly reduced.
Direction Pointing:
The DR600 is directional in nature. It may be configured to detect and measure
the speed of incoming, outgoing, or bi-directional traffic. It then rejects traffic
moving in the opposite direction (unless set to bi-directional). Direction of
detection is configured via the bits in the radar’s MO and MD variables, or
preferably, via the GUI.
Statistics are only gathered for incoming traffic when placed in incoming or bi-
directional mode. No statistics will be collected in outgoing mode.
For optimal performance:
Radar should be mounted as suggested in the section titled “Mounting”
Radar should be pointed into the direction of the oncoming traffic.
Radar should be placed along the side of the road to minimize the angle of the
oncoming traffic to the radar.
oIf radar cannot be placed right along the side of the road, it should be
pointed at least 100-150 feet (30-45 m) up the road into oncoming traffic.
The radar may pick up rotating fans. Avoid pointing it at fans or compressors.
Radar should be mounted at least 3 feet (1 m) high from the road for optimal
performance and at least 6 feet (1.9 m) for maximum pickup distance
Recommended Enclosure for the DR600-OFD:
The DR600-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 is the antenna and the face that must point into traffic.
2. Any cover or window in front of the unit MUST be at least ¼” away from the
face.
3. Do NOT spray any conformal (or other) coating, paint, or other substance on the
antenna.
4. The optimum material to use as a front window is Lexan (Polycarbonate) plastic.
5. The optimum thickness of the polycarbonate window is one half wavelength at
24.125Ghz, or about 3.5 to 3.7mm (0.137” to 0.146”) thick.
a. Alternatively, a thin window of any plastic material may be used. The
maximum thickness in this case should be no more than 1 mm (40 mils).
b. Standard 0.25” thick Lexan should be avoided as it has particularly high
reflection coefficient due to this specific thickness.
6. Other plastic materials may be used as a front window, but the optimum thickness
will wary with the material’s dielectric constant. Please contact us for details.

Alternatively, you may consider the weatherproof version, DR600-DFT, which is
available from Houston Radar.
Hookup:
Power Input:
The DR600 radar features a wide operating input voltage range of 5.0V-30V. In a typical
application, it may be powered from a nominal 12V DC source and will feature best in
class operational power consumption of 8.1mA (average).
This ultra low operational power translates directly into a longer battery life, or the option
to use smaller batteries and solar panels.
Note: The radar employs aggressive power saving measures that include turning off parts
of the circuit that are not being used at any instant. To get a true measure of the power
usage of the circuit use a multi-meter that has an averaging function and does not suffer
from auto ranging during measurements. Otherwise you will get current readings that
fluctuate from 1 mA to 30 mA.
Your power supply to the radar must be capable of supplying up to 100mA of current for
up to 5 seconds at a time (startup current is higher as the radar is initializing its internal
systems).
Serial Connection:
The DR600 features an RS232 interface that is used to output speed, access statistics
data, and configure the unit.
The RS232 interface is factory set to “cable detect” mode and will power the interface
chip down to save power if the radar RX line is not connected. Cable detect mode may be
disabled and the interface forced ON via a bit in the “MD” variable. This can also be
configured through the GUI.
Measured Speed Output:
The DR600 will send out the measured speed via the ASCII interface as a 3 digit speed
with an optional direction indicator. The format is:
[?,+]nnn[.ddd][\r,\n]
The format of the speed output can be adjusted to any combination of:
“?”: Optional prefix sent when 000 selected to be sent when no vehicles are detected
“+”: Optional prefix sent when nnn speed is sent for incoming vehicles
“-“: Optional prefix send when nnn speed is sent for outgoing vehicles
“nnn”: Three digit ascii speed in the units selected via the UN variable
“.ddd”: Programmable number of digits (0-3) after decimal point
“\r”: Carriage Return character, optional line ending
“\n”: Line Feed character, optional line ending

Page 8 of 35
At least one or both of the line endings must be selected with ASCII format. No line
ending is not an option. Please see serial port configuration section for details on how to
select the above format.
Alternatively, the radar may be set to output a single byte speed in binary format. No line
termination is issued when format is set to binary. A fractional value cannot be output
when the binary output mode is selected.
Setting variables from an ASCII Terminal program via ASCII commands:
All the radar variables can 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.
All settings are written to FLASH memory and are non-volatile. Do not update
settings on a periodic basis, e.g. every second or every minute. Only change settings
when the user needs it. The FLASH memory has a limited number of write cycles
and will wear out with an excessive (>10,000) number of writes. On the other hand,
setting the variable to the same value repeatedly is OK because the radar recognizes
that the variable has not changed and does not update it in FLASH.
The ASCII commands are:
get(to get a config variable)
set(set a config variable to a supplied value)
reset(resets the radar. Required after changing variables MO, MD, RS, RA, and CY.
LO, HI, SP, ST, SF, UN do not require a reset.) Some variables may not be present on all
radars.
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.
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 characters, such as the return character, do not generate
"ERROR" messages unexpectedly.
To set a variable (variables are documented in the user manual):
set: <case sensitive variable name> <value>[Enter]
e.g.
set:LO 5
alt format:

Page 9 of 35
set:LO=5
sets the low speed cutoff to 5 etc.
To get a variable (variables are documented in the user manual):
get:<case sensitive variable name>[ENTER]
e.g.
get:LO
returns
LO=5 (if value is presently set to 5).
If sending the ASCII command via an attached microcontroller, the “[ENTER]” key
press should be replaced by the carriage return and/or line feed ASCII charact

Note 1: See Appendix A for detailed description on how to hookup an external
device to be triggered when radar detects incoming objects. Incorrect hookup may
result in the output devices being destroyed and will not be covered under
warranty.
The DR600 features two low impedance outputs that can trigger/turn on an
external display/device to bring it out of power saving mode when a vehicle is
detected. Both outputs are under radar software control and the typical
functionality is to turn both on together when a vehicle is detected. This logic,
however, is completely customizable. See later section for details.
When a vehicle is detected, with the typical configuration, and the speed is above
the “LO” speed limit and below the “HI” speed limit, both pins are pulled down to
GND and held low as long as a vehicle is tracked. These pins are released as soon
as the radar detects no further traffic.
These are “open drain” (AKA open collector) outputs capable of sinking 500 mA
each. You must limit the current externally to ensure that no more than 500 mA
goes into each pin when they turn on. They may be connected in parallel to
double the sink capacity to 1000 mA.

Houston Radar DR600 User Manual
Page 12 of 35
USE
Turn on the power to the DR600 to make it operational. No other action is required. The
radar will typically activate OUT 1 and OUT 2 open drain outputs whenever it detects a
vehicle that is above the programmed lower speed limit (the “LO” value) and below the
programmed high limit (the “HI” value). The units (e.g. km/h, mph, fps, mps) are
determined by UN variable. The trigger output behavior can be changed. See later
section.
The radar will also keep sending out the speed in user selected ASCII format over the
serial interface while a vehicle is tracked (If detection direction selection matches the
direction of travel for the vehicle).
Connect the radar to a PC RS232 serial port and use the provided Windows configuration
software to program the high speed limit (“HI” variable). If you do not want an upper
detection limit, set this value to the maximum value available on the slider control. If
you wish to disable the upper limit by setting the “HI” variable directly, set the variable
to the highest detectable speed listed in the radar specifications.
Set the “LO” variable to set the lower detection speed limit. The outputs will be de-
asserted for vehicles below this speed limit.

Internal Clock:
The radar has a built in clock/calendar function. This is used to keep the time to
date/time stamp the historical archive records saved by the Advanced In-Radar traffic
statistics collection feature that is available as an option in the radar.
The DR600 radar features a built in clock backup battery that will keep the clock
time in the case of power failure for over 10 years.
Configuring the Unit:
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 set the configuration variables directly. This is
very beneficial when the radar is part of a system and connected to another
microcontroller.
The radar configuration variables and their functionality are described below.
The radar supports significantly more options than can be easily listed here. If you
need to manipulate the variables directly, we highly recommend contacting us or
using the GUI to set the options. After setting the options in the GUI, the radar
configuration can be downloaded, and the variable names and values can be
examined with a text editor.
Configuration
Variable Name
Description
RS
Sets the primary RS232 serial port’s baud rate and output format. Do
not change this value unless you understand the implications.
RA
Sets the auxiliary RS232 serial port’s baud rate and output format. Do
not change this value unless you understand the implications.
UN
Lower Byte: Sets the internal speed units of the radar. All LO, SP, HI,
SI speeds are interpreted to be in these units.
0 = MPH 2=FPS (Feet per second)
1 = KM/H 3=MPS (Meters per second)
Upper Byte: Sets number of digits after decimal point.
LO
Low speed cutoff. Vehicles are not detected below this speed. Should
be set to be less than HI. Speeds above this limit trigger the O/P1 and
O/P2 outputs (depends on trigger configuration) and ASCII speed
output.
HI
High speed cutoff. Vehicles are not detected above this speed. Should
be set higher than LO speed. Speeds below this limit trigger the O/P1
and O/P2 outputs (depends on trigger configuration) and ASCII speed

output.
SP
Flashing speed limit. Any speed higher than this value “flashes” the
speed output at 50% duty cycle. To “flash” the ASCII speed, 000 are
interspersed in the “nnn” speed output on the serial port. Set to HI
value to never “flash” the speed output.
SF
1 = Select Fastest Target if multiple targets are detected on the road.
0 = Select Strongest Target if multiple targets are detected on the road.
ST
Target detection sensitivity. Valid values are from 10 to 100 and are a
percentage of max range. Note: This is not a range setting but detection
sensitivity. Thus, if vehicles are being detected at 1000 feet with an
“ST” value of 100, an “ST” value of 50 will reduce detection range to
approximately 500 feet (range values provided are for example only).

1: Outgoing
2: Bi-directional
CY
Radar cycle time in ms. Valid values include 50-1000ms. As cycle
time decreases, power increases. Range is decreased by approximately
30% if cycle time is less than 115ms, and 50% if cycle time is less than
85ms. It is advised to place the radar in range boost mode if cycle time
is below 85ms. The only valid value for gathering traffic statistics is
380ms. Setting any value other than other than 380ms on a statistics
activated radar will prevent statistics from being recorded.
Configuration Variable Notes:
Note 1: “True Average Speed” output requires the optional Advanced in Radar traffic
statistics collection functionality. Enabling this will disable normal real-time ASCII
speed output.
Note 2:Detection direction is controlled by two different bits. Enabling bi-directional
traffic by setting bit 8 of “MD” to 1 will override the value set in “MO” bit 12.

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.
Select radar units. Units may be set to
one of the values shown. Additional
units may be added in the future.
