UART 2 Mode
The system board supports IrDA function for wireless connectivity
between your computer and peripheral devices. You may not use
IrDA (J21) and the COM 2 serial port (J5) at the same time. If you
are using the COM 2 serial port, make sure this field is set to
Standard.
To use the IrDA function, follow the steps below.
1. Connect your IrDA cable to connector J21 on the system
board.
2. Set the UART 2 Mode field to the type of IrDA standard
supported by your IrDA peripheral/device (HPSIR or ASKIR).
For better transmission of data, your IrDA peripheral device
must be within a 30
o
angle and within a distance of 1 meter.
3. Set the IR Function Duplex and TX,RX Inverting Enable fields
appropriately.
