Section 3 — Installation

Single Video Reference – Redundant Operation

In the arrangement shown in Figure 39, the same video reference is brought

to the Primary and Secondary Matrix boards. If the Primary board fails the

system will switch automatically to the Secondary board.

The system will detect that the same reference signal is connected to both

inputs and automatically combine Sync Bus 0 with Sync Bus 2. When con

figuring the output boards, only Bus 0 is a valid selection.
