PS/2 Keyboard and Mouse Interface
The Super-I/O of the JRexplus-DC 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.
