Certain models of Belkin Secure KVMs feature a Dedicated Peripheral Port, labeled CAC on the KVM. This is a one-way, slow-speed, USB 1.1 port designed for USB authentication devices. The CAC port, by default, is switchable and shared amongst all the computers connected to your KVM or can be locked to a specific port. Belkin KVMs leave the factory pre-programmed to accept the most common CAC reader devices, but additional devices can be added through the Administration Configuration Terminal.
