This configuration allows you to make a full functionality speed sign with a “SLOW
DOWN” type message that is activated if the measured speed is above the speed limit or
above the high-speed display cutoff and a “THANK YOU” type message activated below
the speed limit. Please refer to Appendix B for a schematic of this simple external
message board. Alternatively contact us to purchase this message board.
DR600 Open Drain Outputs:
In addition to the external “Slow Down” output option, the standard DR600 open drain
outputs can still be utilized on the auxiliary connector. Please refer to the DR600 user
manual for information regarding these outputs.
Collecting and Analyzing In-Radar Traffic Statistics
The PNL18 supports optional “In-Radar” advanced traffic statistics collection. This
feature is sold separately. If this feature is 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 (32 bit and 64 bit versions) computer
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 PNL18 In-Radar stats software 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.
Internal Clock:
The PNL18/DR600 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
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.
