KV9622A
Appendix: Troubleshooting
Solution #2:
Turn off the device driver (not keyboard or mouse) before switching
the computer.
Problem:
AutoScan does not switch a PC automatically and the ServSwitch
beeps.
Cause:
All PCs are off or only one PC is powered on. The scan mode works for
powered-on computers only.
Solution:
Power on the computers.
Problem:
The resolution is not good or the video is not working.
Cause:
Improper ServSwitch video settings.
Solution:
Press the FUNC button on the rear of the unit to adjust the optimal
video signal strength according to the length or quality of DVI cable (4-port model
only).
Problem:
When users plug and unplug the DVI connector or switch from port to
port, there is no video signal.
Cause #1:
Some DVI video cards don’t respond to simultaneous switch signals.
Solution #1:
Wait a few seconds, then use the Function button to adjust the
video signal strength.
Cause #2:
You are using analog video through a DVI-I cable with the KV9622A.
Solution #2:
The KV9622A does not support analog video. You will need to use
digital video signals only with the 2-port model.
