2430 Super VGA Video Card – 14
Flat Panel Display
1.
The DC to DC converter is used to supply a DC voltage for the
bias voltage required on some flat panel displays. This voltage
must be set prior to connecting the display. A BIOS for the
panel must already be programmed in the EEPROM.
2.
Configure jumper block W2 for the polarity of the voltage
required.
BIAS Polarity: W2
Pins
Jumpered
Description
[1-2]
Negative DC-DC output to J2, pin 3
[2-3]*
Positive DC-DC output to J2, pin 3
* = default
3.
Power on the 2430 and measure Vee at J2, pin 3 and adjust R11
to the correct voltage for your display.
NOTE: Without a flat panel BIOS programmed into the
EEPROM and W1[1-2] installed, Vee will not come up.
4.
Power off the 2430 and connect the flat panel display to the
2430 using a 50–position IDC connector. The following table
lists the pin number and function for J2:
