COM 2 COM 4
COM 1, COM 3 and COM 4 are fixed at RS232.
The pin functions of COM port 2 will vary according to JP6's setting. JP6 allows you to con-
figure the Serial COM port 2 to RS422 or RS485. Refer to "COM 2 RS422/485 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.

The display ports consist of the following:
•
1 VGA port
•
1 DP 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.
DP Port
The DisplayPort is a digital display interface used to connect a display device such as a com-
puter monitor. It is used to transmit audio and video simultaneously. The interface, which is
developed by VESA, delivers higher performance features than any other digital interface.
DVI-D Port
The DVI-I port is used to connect an LCD monitor. This port supports DVI-D signal only.
Connect the display device's cable connector to the DVI-I port. After plugging the cable con-
nector into the port, gently tighten the cable screws to hold the connector 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.
Driver Installation
Install the graphics driver. Refer to chapter 4 for more information.
