9086 Functional Description
1-14 9086-SD PRODUCT MANUAL 9086-OM (V4.3)
9086 Rear I/O Modules
The 9086 physically interfaces to system video and audio connections using a
Rear I/O Module. Figure 1-7 shows a typical 9086 Rear I/O Module.
All inputs and outputs shown in the 9086 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 9086 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 9086 Rear I/O Modules is shown and described in
9086 Rear I/O Modules (p. 2-4) in Chapter 2, “Installation and Setup”.

In this example, an RM-9086-B Rear I/O
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-9086-A/S shown here
accommodates the signal complement shown for two
adjacent 9086 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 9086 cards
in slots 1 and 2, the right column
serves 9086, slot 1 and the left
column serves 9086, slot 2.
