IrDA Connector
IrDA
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.
The IrDA connector is for connecting an IrDA module. Connect the cable from your IrDA mod-
ule to IrDA connector.
BIOS Setting
Set “UART2 Mode Select” (“Onboard Super IO Device” field) in the Integrated Peripherals sub-
menu of the BIOS to the type of IrDA standard supported by your device.
Driver Installation
You may need to install the proper drivers in your operating system to use the IrDA function.
Refer to your operating system’s manual or documentation for more information.
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.
