9381 Functional Description
1-14 9381 PRODUCT MANUAL 9381-OM (V4.3)
9381 Rear I/O Modules
The 9381 physically interfaces to system video connections at the rear of its
frame using a Rear I/O Module.
All inputs and outputs shown in the 9381 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 9381 card edge connections to BNC
connectors that interface with other components and systems in the signal
chain.
These required BNC connections are provided by either an 8310-BNC or
8310-C-BNC frame (which both have a built-in BNC connector backplane
module), or by using an optional 9381 Rear I/O Module.
