2.13 VGA interface connections
The PCM-4825/4825L board's SVGA interface can drive conven-
tional CRT displays and is capable of driving a wide range of flat
panel displays, including electroluminescent (EL), gas plasma,
passive LCD and active LCD displays. The card has two connec-
tors to support these displays, one for standard CRT VGA monitors
and one for flat panel displays.
2.13.1 CRT display connector (CN15)
CN15 is a 15-pin, D-SUB connector commonly used for conven-
tional CRT displays.
Pin assignments for CRT display connector CN15 are detailed in
Appendix A.
2.13.2 Flat panel display connector (CN6)
CN6 consists of a 44-pin, dual-in-line header.
The PCM-4825/4825L provides a bias control signal on CN6
which can be used to control the LCD bias voltage. It is recom-
mended 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-4825/4825L board's power is applied, the
control signal is low until just after the relevant flat panel signals
are present.
Configuration of the LCD type is done completely via the software
utility. You do not have to set any jumpers. Refer to Chapter 3 for
software setup details.
Refer to Chapter 3 for details on connecting the four standard
LCD's: Sharp LM64183P, Toshiba LTM10C042, Sharp 64C142,
and Planar EL Display.
