Parallel Port Mode
This option specifies the parallel port mode. The Optimal default setting is
Normal.
The Fail-Safe default setting is
Disabled.
The settings are:
Setting
Description
Normal
The normal parallel port mode is used.
Bi-Dir
Use this setting to support bidirectional transfers on the
parallel port.
EPP
The parallel port can be used with devices that adhere to the
Enhanced Parallel Port (EPP) specification. EPP uses the
existing parallel port signals to provide asymmetric
bidirectional data transfer driven by the host device.
ECP
The parallel port can be used with devices that adhere to the
Extended Capabilities Port (ECP) specification. ECP uses the
DMA protocol to achieve data transfer rates up to 2.5 Megabits
per second. ECP provides symmetric bidirectional
communication.
EPP Version
This option specifies the Enhanced Parallel Port specification version number
that is used if the
Parallel Port Mode
option is set to
EPP. This option can
only be selected if the Parallel Port Mode option is set to EPP
The settings are
1.7
or
1.9.
There are no Optimal and Fail-Safe default settings
because the default setting for the
Parallel Port Mode
option is not
EPP.
Parallel Port DMA Channel
This option is only available if the setting for the
Parallel Port
Mode
option is
ECP.
This option sets the DMA channel used by the parallel
port. The settings are (
DMA Channel 1
or
3
. The Optimal and Fail-Safe default
settings are
3.
