RxD , TxD Active: Defines 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:
H
Hi, Lo (default)
H
Lo, Hi
H
Lo, Lo
H
Hi, Hi
IR Transmission Delay: When set to “Enabled”(default), utilizes the
capability of the mainboard to allow faster infrared transmission rates. The
options are “Enabled” and “Disabled.”
UR2 Duplex Mode: This field is available when UART Mode Select is
set to either ASKIR or IrDA. This item enables you to determine the
infrared (IR) function of the onboard infrared chip. The options are “Full”
and “Half” (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:
H
378/IRQ7 (default)
H
278/IRQ5
H
3BC/IRQ7
H
Disabled (disables the onboard parallel port).
Parallel Port Mode: There are four options the setting “SPP” (Standard
Parallel Port), “EPP” (Enhanced Parallel Port), “ECP” (Extended Capa-
bilities Port), “ECP+EPP” and “Normal” Change the mode from
“SPP”(default) to the enhanced mode only if your peripheral device can
support it.
EPP Mode Select: Sets the EPP specification. There are two op-tions-
“EPP1.7” (default) and “EPP1.9.”
