Video is present but is distorted
If video is present but is distorted, check the following:
Turn the “S” switch Off.
If using a CRT monitor, check the cable and connections going from the J6
connector to the monitor.
If using a flat panel display, check the following:
1. Cable and connections going from the 5266 to the flat panel display.
2. Power cable going to the flat panel display.
3. Power module for the flat panel. Make sure that the power module has
enough current capacity to power both the 5266 and the flat panel.
4. BIOS Setup settings for your flat panel.
No serial console activity
If the serial console does not appear to be functioning correctly, check the following:
Turn the “S” switch Off.
Make sure the COM1/2 connector on the 5266 is used.
Make sure a null modem adapter is installed between COM1 of the VTC-20F
cable and the serial port of your PC.
Make sure that your terminal emulator (such as HyperTerminal) on your PC is
set up properly. Refer to the Console devices chapter. Refer to the
HyperTerminal manual for information on setting up communication
parameters.
After verifying the above conditions, you can monitor voltage levels by
connecting an oscilloscope between the TxD* line on COM1 and ground. After
power-up, you should see a burst of activity on the oscilloscope screen. The
voltage level should switch b/–8V.
Garbled serial console screen activity
If you do get activity on your console screen but the message is garbled, check the
following:
Turn the “S” switch Off to ensure the default settings for COM1. The default
baud rate is 115200.
Make sure that your terminal emulator (such as HyperTerminal) on your PC is
set up properly. Refer to the Console devices chapter. Refer to the
HyperTerminal manual for information on setting up communication
parameters.
