COM (Serial) Ports
COM 4 to COM 10 are fixed at RS232.
The pin functions of COM 3 port will vary according to JP2’s setting. JP15 (for COM 1) and
JP14 (COM 2) are used to configure Serial COM ports to pure RS232 or RS232 with power.
Refer to “COM3 RS422/RS485 Select” and “COM1/COM2 RS232/Power Select“ in this chapter
for more information.
The serial ports are asynchronous communication ports with 16C550A-compatible UARTs that
can be used with modems, serial printers, remote display terminals, and other serial devices.
Connecting External Serial Ports
Your COM port may come 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 serial port cable to the COM
connector. Make sure the colored stripe on the ribbon cable is aligned with pin 1 of the COM
connector.
BIOS Setting
Configure the serial COM ports in the Advanced menu (“Super IO Configuration” submenu) of
the BIOS. Refer to the chapter 3 for more information.

Graphics Interfaces
The display ports consist of the following:
• 1 VGA port
• 1 DVI-D port
VGA Port
The VGA port is used for connecting a VGA monitor. Connect the monitor’s 15-pin D-shell cable
connector to the VGA port. After you plug the monitor’s cable connector into the VGA port,
gently tighten the cable screws to hold the connector in place.
DVI-D Port
The DVI-D (Digital Visual Interface) port is used to connect a digital LCD monitor or LCD TV.
Connect the display device’s cable connector to the DVI-D port at location CN13. After you
plug the cable connector into the DVI-D port, gently tighten the cable screws to hold the con-
nector in place.
BIOS Setting
Configure the display devices in the Chipset menu (“System Agent Configuration” submenu) of
the BIOS. Refer to the chapter 3 for more information.
