2.9 Ports and Connectors
2.9.1 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 por t (CN1 - 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 J11 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 J11. Make sure
the colored stripe on the ribbon cable is
aligned with pin 1 of connector J11.
Mount the card-edge bracket to the system chassis.
