The CS1708A KVM switch is a control unit which makes it possible to control several computers from a single PS/2 or USB console (keyboard, monitor and mouse). A single CS1708A can control up to 8 computers. Up to 31 additional KVM switches can be daisy-chained with the switch to manage up to 256 computers from a single console. The device also has a front USB port to which you can connect a USB device. The computers connected to the unit will then be able to access this USB device on a staggered basis.
