Mouse

My mouse is not detected during boot up. What can be the cause?

One of the following may be the case:

Please verify that all mouse cables are inserted properly. Check especially for a mix-up with the PS/2 keyboard cable, they have the same kind of connector and are therefore easily confused.

Read your motherboard documentation and make sure that the PS/2 mouse IRQ is enabled. (This can be set for most computers in the BIOS setup pages)

The computers boot properly but I cannot use the mouse. What can be the cause?

One of the following may be the case:

Please verify that the mouse is plugged into the DKVM-2/4 unit properly.

Make sure the mouse works properly when plugged into a computer directly. You will need to reboot the system to test this.

Try using a different mouse.

Verify that the mouse complies with the PS/2 standard. A combination mouse will work, but it must be set to PS/2 mode and the correct serial mouse to PS/2 adapter must be used. A serial mouse with a serial - PS/2 adapter will not work, since the mouse signals do not comply with the PS/2 standard.

Make sure that the power adapter is plugged in at both ends and that it is working correctly. Its rating must be 9V 600mA.
