Hardware Installation
The two 9-pin connectors are for connecting external serial ports.
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 COM 1 or COM 2 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 COM
1 or COM 2.
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.
