Aten Desktop KVM Switch 4 Port Single Display VGA, 4x Custom KVM Cables Included, Selection Via Front Panel, Auto Scan Mode,

The CS84U PS/2-USB KVM Switch is a desktop control unit that allows users to access four computers from a single KVM console (PS/2 or USB keyboard and mouse, and VGA monitor). In addition, CS84U comes with ATEN’s new Video DynaSync™ technology, which eliminates boot-up display problems and optimizes resolution.

Setup is fast and easy; simply plug cables into their appropriate ports. There is no software to configure, no installation routines, and no incompatibility problems. Since the CS84U intercepts keyboard input directly, it will work on multiple computing platforms.
