Different devices implement the RS-232 standard in different ways. If

you are having problems with a serial device, be sure to check the pin

assignments for the connector.

2.7 PS/2 Keyboard and Mouse Conn (CN11)

Two 6-pin mini-DIN connectors (CN11) on the motherboard provide

connection to a PS/2 keyboard and a PS/2 mouse, respectively.

2.8 External Keyboard Connector (CN12)

In addition to the PS/2 mouse/keyboard connector on the AIMB-744's

rear plate, there is also an extra onboard external keyboard connector.

This gives system integrators greater flexibility in designing their sys-

tems.
