What do I do if my keyboard is not working properly through the KVM-121/221?

If your keyboard is not functional, not detected, or there is a keyboard error on bootup, check the following:

  • Make sure that the keyboard is properly connected to the KVM-121/221. Check that the purple coated keyboard cable is securely plugged into the correct PS/2 keyboard port (purple colored) and not the PS/2 mouse port (green colored).
     
  • Verify that the keyboard works when plugged into the computer directly. You will have to shut down your computer first to do this.
     
  • Read you 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.
