SECTION 7—OPERATION
7.14
7.5 VSS PULSE OPERATION
The Raptor RP-1 has hardware and software in place to
interface the unit to the patrol vehicles speed sensor (VSS).
The speed sensors input pulses steer the DSP in the search
for the Doppler patrol signal. This patented technique,
(TruTrak) virtually eliminates problems of patrol
shadowing and patrol combining.
Once the synchronization procedure has been completed no
further action is needed unless the Raptor RP-1 is placed in
another patrol vehicle. If so, the operator must repeat the
synchronization procedure for the new vehicle if he wishes
to use the speedometer pulse input.
The radar may be operated with or without the speedometer
pulse input. If it is not connected to the speedometer pulse
input, it will operate as standard directional radar. If the
Raptor RP-1 is connected to the speedometer pulse input, it
will operate as a standard directional radar on power up.
When speedometer pulses are detected, it will
automatically begin using the stored synchronization code.
7.5.1 AUTOMATIC MODE SWITCHING
The Raptor RP1 with speedometer interface that has
been synchronized will perform A utomatic M ode
S witching (AMS). When the unit has received
speedometer pulses, after power up, it will automatically
switch to moving mode while the vehicle is traveling and to
stationary mode when the vehicle stops.
NOTE: AMS will not change modes if the operator has
Locked speeds. If speeds were Locked in
stationary mode and then the vehicle begins
traveling, the unit will be placed in Hold.
