Functional Description

The PS/2 Device User Module supports a standard PS/2 keyboard or a standard PS/2 mouse. A PS/2 connector is a 6-pin mini-DIN connector. It can be used for connecting either a keyboard or a mouse with a compatible computer. You must choose to support either a keyboard or a mouse with the PS/2 Device User Module. Choose to support either the keyboard command set or the mouse command set when you select the user module. If you wish to change from one to the other after the user module is selected, right click on the user module icon and select User Module Selection Options. By convention, connectors that support keyboards are color coded purple, and ports that support mice are color coded green. With the addition of the USB Device User Module, you can create a single device that supports a USB and PS/2 combination device.
