COM (Serial) Ports
COM 1 and COM 2 are fixed at RS232.
The pin functions of COM 2 will vary according to JP6’s setting. JP6 allows you to configure
COM 2 to RS232 or RS232 with power. Refer to “COM 2 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 COM ports 1/2 in the Advanced menu (“SIO NUVOTON6106D” submenu) of the
BIOS. Refer to the chapter 3 for more information.
