COM (Serial) Ports

COM 1
VGA
COM 1:
RS232/422/485
COM 2:
RS232/422/485
COM 1 port
The pin functions of COM 1 port will vary according to JP7's setting. JP9 is used to configure
Serial COM ports to pure RS232 or RS232 with power. Refer to "COM1/COM2 RS232/422/485
Select" and "COM1/COM2 RS232/Power Select" in this chapter for more information.
COM 2 port
The pin functions of COM 1 port will vary according to JP11's setting. JP14 is used to configure
Serial COM ports to pure RS232 or RS232 with power. Refer to "COM1/COM2 RS232/422/485
Select" and "COM1/COM2 RS232/Power Select" in this chapter for more information.
COM 3 to COM 6 are fixed at RS232.
The pin functions of COM 1 and COM 2 ports will vary according to JP7's (for COM 1) and
JP11's (for COM 2) setting. JP9 (for COM 1) and JP14 (for COM 2) are used to configure Serial
COM ports to pure RS232 or RS232 with power. Refer to "COM1/COM2 RS232/422/485 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 ("SIO NUVOTON6106D" submenu) of
the BIOS. Refer to the chapter 3 for more information.

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-I Port
The DVI-I (DVI-D Signal) 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
DP Port
The DP port which carries both digital audio and video signals is used to connect a LCD moni-
tor or digital TV that has the DP port.
BIOS Setting
Configure the display devices in the advanced menu ("Video Configuration" submenu) of the
BIOS. Refer to the chapter 3 for more information.
