2-2 Configuring the
Parallel Pro
Prior to installing the
Parallel Pro
, verify the configuration
about your computer. The factory default jumper settings
should work with most systems. However, you should make
sure that the default settings on the board are different from
any other existing devices' in your system. A conflict
results when two addresses are the same. Please refer
to the following sections for alternate jumper settings and
Chapter 3: Verifying and Configuring System Resources
for
more information regarding system resources.
2-2.1 Setting Jumpers
The following illustrates the installed positions on a 2-pin
jumper. It also shows the non-jumpered position and position
for convenient storing.
To change a jumper, simply remove a selected jumper by
pulling up on its pull tab. To install a jumper, center it over the
two appropriate pins and push down gently until it is seated.
