UART Mode Select
Your system may offer a variety of infrared modes on the second serial
port. The options are Standard, HPSIR or ASKIR.
!
RxD, 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.
!
IR Transmission Delay
This field allows you to “Enable” or “Disable” the IR Transmission Delay.
!
UR2 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.
!
Use 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.
!
Onboard 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.
