4. Keyboard-video-mouse switch (KVM) control panels

The purpose of the KVM is to select whether you are projecting your laptop or the built-in instructor workstation onto the projection screen. You may encounter several different KVM control panels; see the photos below.

4.1. Four-channel KVMs

These KVMs switch the projector among up to four different sources:

  • Channel 1 selects the built-in workstation.

  • Channel 2 selects the laptop cables.

  • Channel 3 is the ELMO camera, where present.

With the panel below, press the Channel button until the red light lines up with the correct source number. For example, to select the built-in workstation, click this button until lamp #1 is lit.
