9 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.
9.1 Connector
The keyboard/mouse interface is available through the standard miniDIN connector J26 (6 pins). A Y-cable
is deliverable from KONTRON (KAB-PS/2Y-1, part number 96001-0000-00-4)
