Hardware Installation
Serial Ports
The system board is equipped with an onboard serial port (COM
1) at location CN4. It is also equipped with a 9-pin connector at
location J4 (COM 2). The serial ports are RS-232 asynchronous
communication ports with 16C550A-compatible UARTs that can be
used with modems, serial printers, remote display terminals, and
other serial devices.
To connect COM 2, please refer to the following description. The
serial port may be mounted on a card-edge bracket. Install the card-
edge bracket to an available slot at the rear of the system chassis
then insert the cable connector to J4. Make sure the colored stripe
on the ribbon cable is aligned with pin 1 of J4.
Jumper Setting
Use JP6 to configure COM 2. Refer to “COM 2 RS232/AUX Select”
in this chapter for more information.
BIOS Setting
Configure the serial ports in the Integrated Peripherals submenu
(“Super IO Device” section) of the BIOS. Refer to chapter 3 for
more information.
