Black Box KVM Switch - 4-Port, Single-Monitor, VGA, PS/2, Desktop

Control up to four PS/2 computer CPUs with just one PS/2 keyboard, PS/2 mouse, and a monitor. Compact, portable, and powered by the interface, the ServSwitch DT Basic II works with most Windows operating systems and requires no complicated setup. Its small footprint enables you to use it on or under a desk. Switching CPUs is easy. To select ports, use either hotkeys or frontpanel buttons. When you switch manually, the buttons' LEDs light to show you the corresponding active ports. Or you can use the switch's Autoscan function to scan all connected computers automatically, one by one, at 10-second intervals. This way, you can monitor computer activity without having to press any keys or buttons.
