2.2.2 External GPS Receiver
The optional GPS receiver (RC4000GPS) should be mounted in a position (such as the truck's roof)
where it has an unobstructed view of the horizon and sky. It should be mounted outside of the reflector
when in a stowed position, with the connector (on the underside) towards the cable's entry point into the
truck. Care should be taken in the routing of the cable to avoid any problems.
The GPS receiver should be mounted at least three feet from other antennas and electrical generating
equipment. Strong RF interference from other sources may disrupt the GPS receiver's signal reception.
Wiring of the GPS connector is discussed in section 2.1.2.4.16.
Recent RC4000s have been supplied with the Garmin GPS17 or GPS19 receiver models. The following
diagram shows its dimensions.
.
The GPS unit is supplied with 25 feet of cable. The GPS unit is supplied with a flange mounting bracket
as shown above. An optional marine mounting bracket is also provided.
