Vehicle kit circuit descriptions
This section provides an outline of the design
and describes the modular assembly of the
vehicle kit. The vehicle kit contains four PCBs:
■ the accessory probe and charger probe
PCBs, interfacing to the radio and battery;
and
■ the charger and options PCBs, containing
the electronic circuitry.
A block diagram showing how the four PCBs
interconnect and naming the connectors on
each PCB is shown in Figure F-9.
The following subsections and their associated
diagrams expand on the functionality of each
vehicle kit PCB.
Vehicle kit accessory probe PCB
(IPN 220-01506-xx)
This PCB provides the interface to the radio’s
accessory connector. The audio/control
signals connect to the options PCB via a 16-
way MicroMatch ribbon cable. The RF signal
is routed via an MCX connector and coaxial
cable to a BNC connector on the rear of the
vehicle kit. A block diagram of this PCB is
shown in Figure F-10.
