Cobalt Digital COMPASS 9363 Multi-Format Reference Generator - Manual (Page 13)

9363-OM (V1.2) 9363 PRODUCT MANUAL 1-9
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.
