2.3.11 Backplane PCB
The Backplane PCB is the interface that connects the Power
Supplies, VICs, PCBs, and other components together, either
through a direct connection to a connector on the Backplane or
through cables to connectors on the Backplane PCB. Signals are
not modified in any way by the Backplane. It serves only as an
interconnecting point. Refer to Figure 2-17 for a general idea of
how the projector wiring is interconnected through the Backplane
PCB.
