COM 1 port
Please refer to the “
Rear Panel I/O Ports
“ section in this chapter for more information.
COM 2 port
The pin assignments of COM port 2 will vary according to the jumper settings (JP11, JP12, and
JP13). JP14 is used to configure COM 2 to pure RS232 or RS232 with power. Refer to “Serial
Port RS232/422/485 Select” and “Serial Port Power Select“ in Chapter 4 for more information.
COM 3 to COM 6 are fixed at RS232.
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 aligns with pin 1 of the COM con-
nector.
BIOS Setting
Configure the serial ports with more advanced options such as the RS485 auto flow mecha-
nism in the Advanced menu (“SIO NUVOTON6106D” submenu) of the BIOS. Refer to Chapter
7 for more information.
