The CS74U 4-Port USB KVM Switch is a desktop control unit that allows users to access four computers from a single KVM console (keyboard and mouse, audio and VGA monitor). With the CS74U, you can access computers conveniently using port selection pushbuttons located on the unit’s front panel. 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 CS74U intercepts keyboard input directly, it will work on multiple computing platforms.
