VB7007 User Manual

Parallel Port Mode

Set the parallel port mode. To operate the onboard parallel port as Standard
Parallel Port, choose SPP. To operate the onboard parallel port in the EPP mode,
choose EPP. By choosing ECP, the onboard parallel port will operate in ECP mode.
Choosing ECP + EPP will allow the onboard parallel port to support both the ECP
and EPP modes simultaneously.
Settings: [SPP, EPP, ECP, ECP + EPP]

EPP Mode Select

EPP (Enhanced Parallel Port) comes in two modes: 1.9 and 1.7. EPP 1.9 is the
newer version of the protocol and is backwards compatible with most EPP
devices. If your EPP device does not work with the EPP 1.9 setting, try changing
the setting to EPP 1.7.
Settings: [EPP 1.9, EPP 1.7]

ECP Mode Use DMA

ECP (Extended Capabilities Port) has two DMA channels that it can use. The
default channel is 3. However, some expansion cards may use channel 3 as well.
To solve this conflict, change the ECP channel to 1. Select a DMA channel for the
port.
Settings: [1, 3]
