10 PS/2 Keyboard and Mouse Interface

The Super-I/O of the JRexplus LX supports a PS/2 keyboard and mouse. A PS/2 keyboard can be directly

connected to this interface. If you intend to use a PS/2 mouse connect a Y-cable to this interface. There are

many different Y-cables available on the market. Some cables have reverse keyboard/mouse signals. If your

keyboard and mouse do not work connect the keyboard to the mouse side and vice versa.

The keyboard/mouse interface is available through the standard miniDIN connector X8 (6 pins).
