5.6 VGA Interface
The panel PC's AGP VGA interface can drive conventional CRT
displays. It is also capable of driving a wide range of flat panel
displays, including electroluminescent (EL), gas plasma, passive LCD
and active LCD displays. The board has two connectors to support
these displays simultaneously: one for standard CRT VGA monitors,
and one for flat panel displays.
CRT display port information can be found in Section 3.9 this manual.
Pin assignments for the flat panel display connector, backlight
connector and other related connectors are shown in Appendix D.
5.6.1 LCD panel power setting
The panel PC's AGP SVGA interface supports 5 V and 3.3 V LCD
displays. The LCD cable already has a built-in default setting. You do
not need to adjust any jumper or switch to select the panel power.
5.6.2 Panel type select (SW3)
SW3 is a 8-pin dip switch for selecting panel type and display mode. A
1024 x 768 TFT LCD is used in the PPC-153, so the switch is preset
according to the table below. The switch is already defaulted for the
PPC-153's LCD, so it should not be modified. If you require modifica-
tion for a special purpose, we recommend that you consult your
distributor or our sales repreentative for detailed information.
