The IFB-X2000E interface board is designed to be mounted on Sony VPL-
X2000E LCD data projectors so that composite video or S video (Y/C)
signals and audio signals from video equipment can be input/output.

Before installing the board, be sure to turn off the power of the projector and
disconnect the projector power cable from the wall outlet.
1 Pull out the AUDIO OUT plate on the rear of the projector by
loosening the four screws with a screwdriver.
2 Disconnect the 12-pin and 4-pin cable connectors from the AUDIO
OUT plate to remove the plate.
3 Insert the two connectors into the connector plugs on the interface
board.
4 Insert the interface board into the rear panel of the projector.
