Flat panel display connector (CN3)
CN3 consists of a 50-pin, dual-in-line header. Power supplies
(+12 V, -12 V) present on CN3 depend on the supply connected
to the board. Ensure that both CN8 and CN12 are connected for
±12 V power supply.
The mainboard provides a bias control signal on CN3 which can
be used to control the LCD bias voltage. It is recommended that
the LCD bias voltage not be applied to the panel until the logic
supply voltage (+5 V) and panel video signals are stable. Under
normal operation the control signal (ENAVEE) is active high.
When the PCM-5894's power is applied, the control signal is low
until just after the relevant flat panel signals are present.
