Introduction
9083 Functional Description
9083 Rear I/O Modules
The 9083 physically interfaces to system video and audio connections using a
Rear I/O Module. Figure 1-10 shows a typical 9083 Rear I/O Module.
All inputs and outputs shown in the 9083 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 9083 card edge connections to industry
standard connections that interface with other components and systems in the
signal chain.
In this manner, the particular inputs and outputs required for a particular
application can be accommodated using a Rear I/O Module that best suits the
requirements. The required input and outputs are broken out to the industry
standard connectors on the Rear I/O Module; the unused inputs and outputs
remain unterminated and not available for use.
The full assortment of 9083 Rear I/O Modules is shown and described in
9083 Rear I/O Modules (p. 2-6) in Chapter 2, “Installation and Setup”.

Module provides a connection interface
for the signal types shown here.

Where a maximum of five BNC connections can suit
particular I/O requirements, a “split” Rear I/O Module offers
maximum card density within the frame by accommodating
two cards using a module occupying no more area than a
standard module. The RM-9083-A/S shown here
accommodates the signal complement shown for two
adjacent 9083 cards. (Split modules are identified by “/S” in
the part number.)
Viewed from rear, the right column
of BNC connectors accommodates
the right-most card, with the left
column accommodating the
adjacent card to the left.
In this example with two 9083 cards
in slots 1 and 2, the right column
serves 9083, slot 1 and the left
column serves 9083, slot 2.
