Video/Audio cards
The FR1AVframe has six slots for Crystal Vision video or audio cards. Only Crystal Vision cards
should be fitted. The signal connections to these are made through rear modules. The operation and
connections of each card and associated rear modules are described in the documentation relating to
that card. All Crystal Vision cards can be inserted and removed while the frame is powered without
damage.

Rear Signal Connections
The signal connections to the cards are made through a range of rear modules. The FR1AV frame will
be supplied with an appropriate selection of these for the cards installed in it. Unused slots will be fitted
with blanking plates. Details of signal types and pin-outs are given the documentation supplied with
each Crystal Vision video or audio card.
The rear modules are held in place by a retaining bar at each side. These run the height of the frame
and provide mechanical support as well as ensuring EMC compliance.
It is possible to move, add, or change the rear modules if new or different cards are to be used in the
frame. This should be done as follows: -
1.
Disconnect the mains power leads from the FR1AV frame.
2.
Identify the rear modules or blanking plates to be removed. Using a cross-head screwdriver undo
the two screws on the retaining bar on each side of these module(s). Remove the retaining bars.
3.
Pull the rear module(s) straight off the rear of the frame.
4.
Check that the rear modules that will be fitted to the frame have the relevant labels properly
attached using the retaining pins.
5.
Fit the new modules by pushing them straight on to the connectors.
6.
Hold any blanking plates in place while the retaining bars are refitted. Ensure that both screws on
the retaining bar is fully tightened to maintain mechanical integrity and EMC compliance.
7.
To maintain product safety and EMC compliance the rear of the frame should be filled with
Crystal Vision connector units and blanking plates before power is reapplied.
