CONFIGURING THE RADAR
The DR500 radar may be configured by setting the following internal parameters:
The unit’s internal parameters may be configured by connecting the radar’s RS232 port
to a PC’s RS232 serial port and using the Houston Radar Advanced Stats Analyzer
program’s configuration screen as described here.
The following internal “variables” may be set. Their functions are described below:
Radar
Configuration
Variable Name
Description
RS
Sets the RS232 serial port’s baud rate and output format. Do not change
this value unless a value is provided by Houston Radar.
UN
Sets the internal speed units of the radar. All LO, SP & HI speeds are
interpreted to be in this units.
0 = MPH
1 = KPH
LO
Low speed cutoff. Vehicles are not detected below this speed.
Minimum value is 3. Should be set to be less than HI.
HI
High speed cutoff. Vehicles are not detected above this speed.
Maximum value is 159. Should be set higher than LO speed.
SP
Flashing speed limit. Any speed higher than this value flashes the
trigger output at 2/3 duty cycle, 1Hz.
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
0 = Select Strongest Target
BN
Set from 1 to 60 minutes of binning interval for stats collection.
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 bits mask. The bits controls speed output on primary and
aux serial ports, rapid output update and other functionality. Please
contact us for details for each bit.
KY
Reserved. Do not set unless value provided by Houston Radar
