The system board is equipped with an IrDA connector for wireless
connectivity between your computer and peripheral devices. The
IRDA (Infrared Data Association) specification supports data
transfers of 115K baud at a distance of 1 meter.
Connect your IrDA cable to connectors J11 and J12 on the
system board. Set UART2 Mode Select (Super IO Device
field) in the Integrated Peripherals submenu of the BIOS to the
type of IrDA standard supported by your device. You must have
the proper drivers installed in your operating system to use this
connector. Refer to your operating systems manual or documen-
tation.
Note:
The sequence of the pin functions on some IrDA cable may be
reversed from the pin function defined on the system board.
Make sure to connect the cable to the IrDA connector
according to their pin functions.
