Introduction
9082 Functional Description
9082 Rear I/O Modules
The 9082 physically interfaces to system video connections using a Rear I/O
Module. Figure 1-4 shows a typical 9082 Rear I/O Module.
All inputs and outputs shown in the 9082 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 9082 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 9082 Rear I/O Modules is shown and described in
9082 Rear I/O Modules (p. 2-4) in Chapter 2, “Installation and Setup”.
Figure 1-4 Typical 9082 Rear I/O Modules
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 RM20-9082-A/S shown here
accommodates the signal complement shown for two
adjacent 9082 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 9082 cards
in slots 1 and 2, the right column
serves 9082, slot 1 and the left
column serves 9082, slot 2.
