No CRT or flat panel video
If the LEDs appear to be functioning properly, but there is no video activity,
check the following:
Make sure all PC/104 expansion cards are removed from the PC–600.
This ensures that other cards are not interacting with the PC–600.
Remove the jumper from the “S” position at W12[1–2].
If using a CRT monitor, check the cable and connections going from the
J18 connector to the monitor.
If using a flat panel display, check the following:
1.
Cable and connections going from the J14 connector to the flat
panel display.
2.
Check the power and cables going to the flat panel display.
3.
Make sure that the power module has enough current capacity to
power both the PC–600 card and the flat panel.
If a flat panel BIOS has been programmed into the PC–600 that is
incorrect for the flat panel being used and an analog monitor is not
present or is not displaying the video data correctly, the system can be
booted via the serial console by doing the following:
1.
Remove the “S” and the “V” jumper.
2.
Connect the COM port of a host computer running
HyperTerminal or some other terminal software to COM 1 on the
PC–600 using a VTC-20F/M and a null modem adapter. The
serial port settings on the host computer should be 38.4K baud,
8, N, and none.
3.
Power up the PC–600, it will boot using the serial console
interface. Once the system has successfully booted you can use
the
pgmvideo.exe
utility to either program the desired flat
panel VIDEO BIOS into the PC–600 or program in the
CRT.DAT
file for analog monitor support to recover the system.
4.
Replace the “S” and “V” jumpers and re-boot the system.
Video is present but is distorted
If video is present but is distorted, check the following:
Make sure all PC/104 expansion cards are removed from the PC–600.
This ensures that other cards are not interacting with the PC–600.
