The Aten DVI (digital visual interface) dual link and USB (universal serial bus) based KVM (keyboard, video and mouse) extender with RS-232 serial functionality, 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, it 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, or the harsh environmental influence on a site. This allows users to deploy system equipment over large distances.
