Troubleshooting - D-Link DKVM-4K Quick Installation Manual

Troubleshooting

Keyboard/Mouse
If your keyboard or mouse is not functional, not detected, or there is a keyboard/mouse error on
boot-up, check the following:
- Make sure that the cables are properly connected between the DKVM-4K and the computer(s),
and the keyboard/mouse to the DKVM-4K. Check that the keyboard/mouse is plugged into
correct PS/2 keyboard/mouse port.
- Verify that the keyboard/mouse works when plugged into the computer directly. You will have to
shut down your computer first to do this.
- Try using a different keyboard/mouse.
- If mouse movement is random when switching between computers, try shutting down your
computer and rebooting.
- If a special mouse is used such as a cordless or scrolling mouse, make sure you use generic
PS/2 mouse drivers. A non-standard PS/2 mouse may have extensions on the PS/2 protocol
that are not supported by the DKVM-4K.
- Don't move the mouse or press any mouse buttons when switching from one PC to another.
- Try resetting the mouse by unplugging it from the DKVM-4K for about 3 seconds and reconnecting.
Video
If the image on your monitor is not clear, check the following:
- Verify that all video monitor cables are inserted properly.
- Try lowering the resolution and refresh rate of your monitor.
- Try using a shorter video cable.
- Try rescanning for VGA signal from monitor again.
