Serial Digital I/O Circuit Board
The Serial Digital I/O board is optional, and can occupy various slots from J6-J13.
The Serial Digital I/O circuit board has a number of plug jumpers in order to
accommodate a number of operating circumstances. In addition it has six connectors
that are used to route clock signals to the Audio I/O circuit boards. See Figure 3-31.
The Serial Digital I/O board with embedded audio capability does not have all the
jumpers shown in Figure 3-31. The connectors for clock signals are present on the
board, but there are no clock connections to make since there can be no Audio boards
in use at the same time as the embedded audio Serial Digital I/O board.
