Onboard IR Port:
This item determines which I/O addresses the onboard IR Port controller will access.
[Auto]: The system automatically select an I/O address for the onboard IR Port.
[3F8/IRQ4, 2F8/ IRQ3, 3E8/ IRQ4, 2E8/IRQ3]: Allows you to manually select an I/O address for the
onboard IR Port.
[Disabled]: Disables the onboard IR Port.
UART Mode Select
This item selects the UART 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.
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]: This option allows the parallel port to use [378] 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.
[278]: This option allows the parallel port to use [278] as its I/O port address.
[3BC]: This option allows the parallel port to use [3BC] as its I/O port address.
Parallel Port Mode:
This item specifies the parallel port mode from [SPP], [EPP], [ECP], and [ECP+EPP] mode.
[SPP]: (Standard Parallel Port) Allows bi-directional parallel port operation at normal speed.
[EPP]: (Enhanced Parallel Port) Allows bi-directional parallel port operation at maximum speed.
[ECP]: (Extended Capabilities Port) Allows bi-directional parallel port operation at a speed faster than
the normal mode's data transfer rate.
EPP Mode Select:
This item selects the EPP mode.
