Port ID Numbering
Each CPU port on the switch is assigned a port number (1 or 2 for the GCS1782 and 1,2,2,4 for the
GCS1784). The port numbers are marked on the rear panel of the switch and each switch LED has
a corresponding number for easy identification.
The Port ID of a computer is derived from the CPU port number it is connected to. For example, a
computer connected to CPU port 2 has a Port ID of 2.
The Port ID is used to specify which computer gets the KVM, USB peripheral, and / or audio focus
with the Hotkey port selection method.
Going Directly to a Port
