Troubleshooting / FAQ

My hotkey commands don't work or stopped working

  • Make sure keyboard is plugged into dedicated mouse/keyboard ports
  • Try using Scroll Lock as hotkey trigger, if not, then Right-Ctrl.

My keyboard does not have a Scroll Lock button

  • Use Right-Ctrl, Right-Ctrl, 1 or 2 to confirm trigger isn't already set to Scroll Lock .
  • Press and hold yellow switch button for 15 seconds . If KVM beeps, turn off and back on. Hotkey trigger will now be set to Right-Ctrl.

I accidentally turned Passthrough Mode off and keyboard no longer functions

  • Use a basic 104-key keyboard to turn Passthrough Mode back on.
  • We recommend keeping Passthrough Mode on at all times unless using Linux.
