Reference Connections

Dual References - Redundant Operation

In this arrangement shown in Figure 40, the same video reference is

brought to the Primary and Secondary Matrix boards, and the same AES

reference is brought to both boards. If the Primary board fails the system

will switch automatically to the Secondary board.

The system will detect that the same reference signals are connected to both

boards and automatically combine Sync Bus 0 with Sync Bus 2 and Sync

Bus 1 with Sync bus 3. When configuring the output boards, only

Bus 0 and

Bus 1 are valid selections.
