IrDA and CIR
Connect the cable connector from your IrDA module to the IrDA
connector or CIR connector.
Note:
The sequence of the pin functions on some IrDA/CIR cable
may be reversed from the pin function defined on the system
board. Make sure to connect the cable connector to the IrDA/
CIR connector according to their pin functions.
You may need to install the proper drivers in your operating system
to use the IrDA/CIR function. Refer to your operating system's
manual or documentation for more information.
Serial (COM)
The serial (COM) connector is used to connect modems, serial print-
ers, remote display terminals, or other serial devices. 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
connect the serial port cable to this connector. The colored edge of
the cable should align with pin 1 of this connector.
