Adder single-connector tri cable is a high quality 'combo' KVM cable which combines the VGA video, keyboard, and mouse into one cable with a single connector (to connect to the KVM switch).

Adder Tri Cable style is very convenient because only a single cable is required for each connected computer, while the connectors on the computer end of the cable are color coded to the latest specifications to ensure correct identification.
