Hardware Installation
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 (J4) 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 and/or RS-485 asynchronous communi-
cation port with 16C550A-compatible UARTs that can be used
with modems, serial printers, remote display terminals, and other
serial devices.
BIOS Setting
Configure the onboard serial port in the Integrated Peripherals
submenu of the BIOS. Refer to chapter 3 for more information.
