Introduction
9363 Functional Description
AES Audio Output Channel Status Data
Table 1-2 lists the channel status information that is encoded into the AES
audio data outputted by the 9363.
Note:
The AES channel status settings outputted by the card are non-configurable.
9363 Rear I/O Modules
The 9363 physically interfaces to system video connections at the rear of its
frame using a Rear I/O Module.
All inputs and outputs (except frame distributed reference signals
Frame Ref 1
and
Frame Ref 2
) shown in the 9363 Functional Block Diagram (Figure 1-1)
enter and exit the card via the card edge backplane connector. The
Rear I/O Module breaks out the 9363 card edge connections to BNC
connectors that interface with other components and systems in the signal
chain. See “Installation”, Chapter 2 for Rear I/O Module connections.
