4UART Mode Select

Your system may offer a variety of infrared modes on the second serial port. The options are Standard, HPSIR or ASKIR.

4RxD, TxD Active

This field allows you to set the IR reception/transmission polarity as high or low. To determine which polarity is appropriate you must refer to the docu- mentation for your IR peripheral.

This field is usually found under the Onboard Serial Port 2 option. If you disable the Onboard Serial Port 2 option then you will probably not be able to configure this field.

4IR Transmission Delay

This field allows you to “Enable” or “Disable” the IR Transmission Delay.

4UR2 Duplex Mode

This field appears in an infrared port mode. You have two options: half or full duplex function. The full duplex mode allows bi-directional transmission at a single time where as the half duplex mode only allows transmission in one direction at a time. This setting depends on the nature of your IR pe- ripheral device. Check the IR device’s manual to determine the appropriate setting.

4Use IR Pins

To determine the correct settings for the TxD and RxD signals of your IR peripheral component, you need to consult the components manual.

4Onboard Parallel Port

This item allows you to determine the I/O address and the IRQ for the on- board parallel port. The default settings are adequate and should not give you any problems. If they do you can try to change them.
