2.6 Connecting the Ribbon Cables and Wires of
the Ports and Connectors
2.6.1 Serial Ports
The built-in serial por ts 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 por ts I/O address in the Integrated
Peripherals setup of the Award BIOS.
Connecting the Serial Ports
Two serial port cables
mounted on a card-edge
bracket are provided with the
system board. Connect one
serial port cable to connector
J4 for COM 1 primary serial
port and the other serial port
cable to connector J5 for the
COM 2 secondary serial port.
Make sure the colored stripes
on the ribbon cables are
aligned with pins 1 of
connectors J4 and J5. Mount the card-
edge bracket to the system chassis.
