Mount the rear panel assembly to the end of the bottom cover that has the two round feet using a 3/16” (4.8
mm) pan head screw into each 2D fastener. If the optional P3SVGA board is installed, note that a notch in the
bottom of the board clears the screw for the rear foot (see Figure 18).
Figure 18. Clearance Notch in P3SVGA board.
CAUTION: Severe damage to your P3 may occur if the 40-conductor ribbon cable is not
oriented correctly and properly mated to the connectors as described in the following steps.
Retrieve the front panel assembly and locate the 40-conductor ribbon cable. Note that one edge of the
ribbon cable is colored, usually brown or red.
Plug the ribbon cable into P200 on the display board with the colored edge of the cable at Pin 1 (the bottom
of the connector when the board is oriented normally). Be sure the connectors are properly aligned so that all
pins engage and they are fully mated as shown in Figure 19). One pin has been removed from the connector on
the pc board and the corresponding hole in the cable connector is plugged to help ensure they are properly
aligned end-to-end but check carefully to ensure the connector is mated to both rows of pins.

Mount the front panel assembly on the bottom cover end opposite the rear panel using a 3/16” (4.8 mm)
pan head screw into each 2D fastener.
