9085 Functional Description
1-16 9085 PRODUCT MANUAL 9085-OM (V4.3)
9085 Rear I/O Modules
The 9085 physically interfaces to system video and audio connections using a
Rear I/O Module. Figure 1-8 shows a typical 9085 Rear I/O Module.
All inputs and outputs shown in the 9085 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 9085 card edge connections to industry standard
connections that interface with other components and systems in the signal
chain.
In this manner, the 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 9085 Rear I/O Modules is shown and described in
9085 Rear I/O Modules (p. 2-6) in Chapter 2, “Installation and Setup”.

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-9085-A/S shown here
accommodates the signal complement shown for two
adjacent 9085 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 9085 cards
in slots 1 and 2, the right column
serves 9085, slot 1 and the left
column serves 9085, slot 2.
