5-3-12-1 General Description
The two XD BUS Boards plug into the rear edge connectors on the Relay Board, the TX128 Board(s)
and on the RX-128 Board.
FEP2 ONLY:
The XD Bus boards used on units with two TX boards, with 4D (RT3D), are not backward
compatible and cannot be used on units with one TX card (without 4D (RT3D)). And the XD Bus board
used on units with one TX board cannot be used on units with two TX boards.
FEP2 ONLY:
The connectors for the Relay Board connection, are color coded to match the colors on
the connectors on the Relay Board, to reduce the risk of mixing the two types of XD Bus boards.
The XD signals to and from the probes (via the Relay Board) are routed via this board.
5-3-12-2 Location in the Unit
NOTICE
Two different versions of the XD Bus boards are used due to the different positions for TX board and
RX board on FEP1 and FEP2. The two types can NOT be interchanged.
