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.
