(default), IrDA, or ASKIR. IrDA is an infrared communication
protocol with a maximum baud rate up to 115.2K bps. ASKIR is
Sharp’s infrared communication protocol with a maximum baud rate
up to 57.6K bps.
RxD , TxD Active : Define the voltage level for Infrared module
RxD(receive) mode and TxD(transmit) mode. This setting has to
match the requirements of the infrared module used in the system.
The options are:
Hi, Lo (default)
Lo, Hi
Lo, Lo
Hi, Hi
IR Transmission Delay : When set to “Enabled”(default), utilizes
the capability of the motherboard to allow faster infrared
transmission rates. The options are “Enabled” and “Disabled”
UR2 Duplex Mode : This field is available when UART 2 Mode
Selects is set to either ASKIR or IrDA. This item enables you to
determine the infrared (IR) function of the onboard infrared chip.
The option are “Full” and “Halt” (default).Full-duplex means that
you can transmit and send information simultaneously. Half-duplex
is the transmission of data in both directions, but only one direction
at a time.
Use IR Pins : Use this item to set the IR pins. The options are
“IR-Rx2Tx2”(default) and “RxD2, TxD2”.
Onboard Parallel Port : This option is used to assign the I/O
address for the onboard parallel port. The options are:
378 / IRQ7 (default)
278 / IRQ5
3BC / IRQ7
Disabled (disables the onboard parallel port).
Parallel Port Mode : There are four options: “SPP” (Standard
Parallel Port), “EPP” (Enhanced Parallel Port), “ECP” (Extended
Capabilities Port) and “ECP+EPP” and “Normal”. Change the mode
