Section 3: Technical Information
Field Upgrading
This section explains the procedures for field upgrading your unit with additional composite video (CVBS) input
module(s).
We advise you remove the MON2-3 from the mounting frame and work with the unit on a clean, well lighted
work bench.
Ensure the MON2-3 is disconnected from the power mains.
Remove top cover. Retain screws for later reassembly.
Remove blanking plugs from slot where MAV-1 is to be installed. (Rear panel sections 2A and/or 3A)
Remove flat ribbon cable from rear I/O PC board. (Horizontal removal/insertion.).
Cut termination resistor from rear main board at the point labeled “B Input Cutout”. (Note: this is to allow HI-
Z/75 ohm termination selection from the MAV-1 board).
Install the flat ribbon connector supplied with the interface into the connector the ribbon was disconnected from
in step #4.
Insert the flat ribbon into the rear (horizontal) flat ribbon connector labeled “J3” on the MAV-1 board.
Insert the flat ribbon cable to the front LCD into the inboard (vertical) flat ribbon connector labeled “J4” on
the MAV-1 board.
Attach the MAV-1 to the rear panel using the supplied BNC nuts.
Double check all wiring and connections.
Connect CVBS signal and confirm operation.
Replace cover and return unit to service.
