Hardware Configuration
Configuration rules
Video and audio cards
The cards and their associated rear connector modules are installed in the frame in a
fixed sequence, which cannot be changed. This applies to each separate multi-viewer
system, whether using the single or dual frame types.
Viewing from the front of the frame, the card sequence runs from right to left, starting with
the video input cards. The first card slot position is adjacent to the CPU card.
Audio interface cards (if required), are installed to the left of the video input cards.
Continuing the sequence from right to left, audio input cards are followed by audio output
cards.
Slots 17 and 18
In single multi-viewer frame configurations, slots 17 and 18 are for audio cards only.
Video Cards
Video input cards are always installed working from right to left (from the front of the
frame). Where double width rear connector modules are needed, video loop through
(VidLoop) cards must be used. See ‘Double rear connector modules’ for more
information.
Rear connector modules
A variety of rear connector modules are available to suit different signal formats and
interfacing requirements. These may be single width (occupying one card slot), or double
width (occupying two card slots).
