UART2 Mode Select
The system board supports IrDA function for wireless connectiv-
ity between your computer and peripheral devices. You may not
use IrDA and the COM 2 serial port at the same time. If you are
using the COM 2 serial port, make sure this field is set to Nor-
mal.
To use the IrDA function, follow the steps below.
1. Connect your IrDA cable to connector J6 on the system
board.
2. Set the “UART2 Mode Select” field to the type of IrDA stand-
ard suppor ted by your IrDA peripheral/device. 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 “RxD, TxD Active” and “IR Transmission Delay” fields
appropriately.
