Troubleshooting Tips
Keyboard
If your keyboard is not functional, not detected, or there is a keyboard error on boot-
up, check the following:
•
Make sure that the keyboard is properly connected to the
computer and to the DKVM-2K. Check that the keyboard is plugged into the
correct PS/2 keyboard port and not the PS/2 mouse port.
•
Verify that the keyboard works when plugged into the computer directly. You
will have to shut down your computer first to do this.
•
Read your motherboard documentation and make sure that the PS/2
keyboard’s IRQ is enabled. This can be set for most computers in the
BIOS setup.
•
Try using a different keyboard.
Mouse
If your mouse is not functional, not detected, or there is a mouse error on boot-up,
check the following:
•
Make sure that the mouse is properly connected to the
computer and to the DKVM-2K. Check that mouse is plugged into the
correct PS/2 mouse port and not the PS/2 keyboard port.
•
Verify that the mouse works when plugged into the computer directly. You
will have to shut down your computer first to do this.
•
Read your motherboard documentation and make sure that the PS/2
mouse’s IRQ is enabled. This can be set for most computers in the
BIOS setup.
•
Try using a different mouse.
•
If mouse movement is random when switching between computers, try
shutting down your computer and rebooting.
•
Verify that your computers do not have more than one mouse driver installed
(check your config.sys and autoexec.bat files for Windows) and that you are
using the latest mouse driver.
•
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-2K.
•
Do not 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-2K 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.
