Chapter 2---System Description

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.
