COM (Serial) Ports
COM 2/COM 3/COM 4:
RS232
COM 2
COM 3
COM 4
COM 1: RS485
COM 1 is fixed at RS485 and COM 2 to COM 4 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 is aligned with pin 1 of the COM
connector.
BIOS Setting
Configure the serial COM ports in the Advanced menu (“NCT6106D Super IO Configuration”
submenu) of the BIOS. Refer to the chapter 3 for more information.
