2.7 Ports and Connectors
2.7.1 Serial Ports
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 set the serial ports I/O address in the Integrated
Peripherals submenu of the BIOS.
Connecting the Serial Ports
The system board is equipped
with an onboard serial port (J4 -
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 J5 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 J5. Make sure
the colored stripe on the ribbon cable is aligned with pin 1 of
connector J5. Mount the card-edge bracket to the system chassis.
