Chapter 4: Troubleshooting
KEYBOARD
My keyboard is not detected, or a keyboard error is given during boot-up. What can be
the cause?
Please verify that the keyboard cables are inserted properly.
The computers all boot up properly, but the keyboard is not functional. What can be the
cause?
One of the following may be the case:
• Make sure the keyboard is plugged into the KVM-04P unit properly.
• Verify that the keyboard works when plugged into the computer directly.
(You will have to shut down your computer first to do this).
• Try using a different keyboard.
• Read your motherboard documentation and make sure that the PS/2 keyboard IRQ
is enabled. (This can be set for most computers in the BIOS setup pages)
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 KVM-04P 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.
• When operating the KVM Switch and you find that the mouse was hung, but the keyboard
was working properly, you can press " Scroll Lock + Scroll Lock + M" to wake up
the mouse.
