The system board is equipped with a 9-pin connector for connecting an external serial port. The serial port cable is an optional item and must be purchased separately. Insert the connector that is attached to the serial port cable to the 9-pin connector (J8) then install the serial port bracket to an available bracket slot at the rear of the system chassis. Make sure the colored stripe on the ribbon cable is aligned with pin 1 of the connector.

The serial port is an RS-232 asynchronous communication port with 16C550A-compatible UARTs that can be used with modems, serial printers, remote display terminals, and other serial devices.

BIOS Setting

Configure the serial port in the Integrated Peripherals submenu (“Super IO Device” section) of the BIOS. Refer to chapter 3 for more information.
