The built-in serial ports are RS-232C asynchronous communication ports with 16C550A-compatible UARTs that can be used with modems, serial printers, remote display terminals, and other serial devices.You can select the serial ports’ I/O address in the Integrated Peripherals submenu (“Super IO Device” field) of the BIOS.

Connecting the Serial Ports

The system board is equipped with an onboard serial port (J3 - Teal/Turquoise) for COM 1 primary serial port located at the ATX double deck ports of the board. It is also equipped with a 9-pin connector at location J4 for COM 2 secondary serial port.

One card-edge bracket, mounted with a serial port cable, is provided with the system board. If you want to use the secondary serial port, connect the serial port cable to connector J4. Make sure the colored stripe on the ribbon cable is aligned with pin 1 of connector J4. Mount the card-edge bracket to the system chassis.
