Serial Connection:
The DR-1500 features a dual RS232 and RS485 output that are active at the same time
giving the user an option to connect serial outputs to either port (see serial port diagram).
Speed data is output serially in mph (or Kmph if set via the remote) as three ASCII digits
in the following format:
nnn\n\r
where:
nnn : The three digit ASCIII speed digits in mph/Kmph
\n\r : A new line followed by a carriage return character
This format is compatible with other industry formats including a standard RS232 serial
port on a PC, message boards and speed displays.
Log/Statistics Storage:
The DR-1500 radar has capacity to store the last 60 days of traffic statistics in 5 minute
bins and features a clock/calendar that retains time even when external power is removed.
The clock is used to time stamp the collected statistics.
This feature is an add-on software option. Please contact Houston Radar LLC for
purchase of this option.
