USB DVI Dual Link KVM Extender with Audio and RS-232 (60m). The CE602 is a DVI Dual Link and USB based KVM Extender with RS-232 serial functionality. It allows access to a computer system from a remote console (USB keyboard, monitor, and mouse). Because it allows access to a computer system from a remote console, the CE602 is perfect for use in any type of installation where you need to place the console where it is conveniently accessible, but you want the system equipment to reside in a safe location – away from the dust and dirt of the factory floor, or the harsh environmental influence of a construction site, for example. This allows users to deploy system equipment over large distances.
