COM (Serial) Ports

COM1, COM 3 to COM 6 are fixed at RS232.

The pin function of COM 2 ports will vary according to JP3’s setting. Refer to “COM2 RS232/

RS422/RS485 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 ports in the Advanced menu (“Super IO Configuration” submenu) of the

BIOS. Refer to chapter 3 for more information.
