Thanks to its 1.1kg case, the CS-104U-A is extremely stable, and it doesn't slide backwards when the switch knob is pressed. It is possible to directly select one of the connected PCs only by using the keyboard, because the box has only one switch knob for all four clients. With each press of the button, the port of the next client is activated. The CS-104U-A only works with USB devices and supports two additional USB 1.1 peripherals, such as a scanner or printer, which are also simultaneously available to all clients.

Switching between the connected computers is done with a single knob.

All connection sockets are located on the back of the CS-104U-A.
