USE
Turn on the power to the DC310 to make it operational. No other action is required. The
radar will activate the appropriate OUT 1 and OUT 2 open drain outputs, if enabled,
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 default limits are set
at 3 and 99 at the factory. The units (e.g. kph, mph, fps, mps) are determined by UN
variable.
Connect radar to PC RS232 serial port and use provided Windows configuration software
to program the high speed limit (“HI” variable). The radar de-asserts the trigger outputs
above this limit. If you do not wish an upper detection limit, set this value to 159. This
will ensure that the upper limit is never reached regardless if the units are set to MPH or
KPH.
Set the “LO” variable to set the lower detection speed limit. The outputs will be de-
asserted for vehicles below this speed limit. The lowest value this may be set is 3 MPH
(5KPH).
Green LED flashes at 1/3 Hz (12.5% duty cycle)
rate when radar is running giving a visual OK
signal. In the DC310-OFD version green LED
may be installed on the back depending on the
requested build option.
