[Auto]:
The system automatically select an I/O address for the onboard Serial Port 2.
[3F8/IRQ4, 2F8/IRQ3, 3E8/IRQ4, 2E8/IRQ3]:
Allows you to manually select an
I/O address for the onboard Serial Port 2.
[Disabled]:
Disables the onboard Serial Port 2.
UART Mode Select:
This item selects the Infrared (IR) function mode.
RxD, TxD Active:
This item sets the IR transmission/reception polarity.
IR Transmission Delay:
This option enables or disables the IR transmission delay. When set to [Enabled], the
transmission will be slower. This is recommended when transmission problem arise.
UR2 Duplex Mode:
This item selects the duplex mode required by the IR device connected to the IR port.
Full-duplex mode permits simultaneous two-direction transmission. Half-duplex
mode permits transmission in one direction only at a time. Refer to your IR KIT user's
guide to find out which setting is correct.
Use IR Pins:
Two options are available: RxD2, TxD2 and IR-Rx2Tx2. The default setting is
IR-Rx2Tx2
.
If you choose
RxD2, TxD2
,
your motherboard must support a COM port IR KIT
connection. Otherwise, you can only choose the
IR-Rx2Tx2
to use the IR header on
your motherboard to connect your IR KIT.
Please use the default setting.
Onboard Parallel Port:
This item specifies the I/O address used by the parallel port.
[Disabled]:
This option prevents the parallel port from accessing any system
resources. When the value of this option is set to [Disabled], the printer port becomes
unavailable.
[378/IRQ7]:
This option allows the parallel port to use [378/IRQ7] as its I/O port
address. The majority of parallel ports on computer systems use IRQ7 and I/O Port
378H as the standard setting.
