2.5.2 Serial Ports
The system board is equipped with a COM connector (Teal/
Turquoise) at location J4 of the system board for connecting an
external serial port. It is a RS-232C asynchronous communication
port with 16C550A-compatible UART that can be used with a
modem, serial printer, remote display terminal or other serial devices.
The serial port may be mounted on a card-edge bracket. Install the
card-edge bracket to the system chassis then insert the cable con-
nector to J4. Make sure the colored stripe on the ribbon cable is
aligned with pin 1 of J4.
BIOS Setting
Select the serial ports’ I/O address in the Integrated Peripherals
submenu (“Super IO Device” field) of the BIOS. Refer to chapter 3
for more information.
