Installing the Parallel lnterface Card
Follow the steps in this section if you need to install the
bidirectional parallel interface card in your computer. You may
also need to configure the card before you install it.
Some computers come with a built-in bidirectional parallel
interface. You do not need to install the parallel interface card if
your computer has a built-in interface that you are not
currently using. If you will connect the scanner to an existing
interface, skip to “Setting Up the Scanner” on page 7.
Note:
Standard (unidirectional) and bidirectional parallel interfaces look the
same but operate differently. Your scanner does not work with a
standard parallel interface, so check your computer manual to make
sure you have an unused bidirectional parallel interface before you
connect the scanner to it.
Configuring the Card
The parallel interface card contains jumpers that select the port
address (LPT1 or LPT2) and interrupt (IRQ5 or IRQ7) it uses.
You may need to change the jumper settings if there is a
conflict with your computer’s parallel port settings. See your
computer manual for information about the port address and
interrupt used by its parallel port.
The bidirectional parallel interface card default settings are:
Cl
Port address LPT2
Cl
Interrupt IRQ5.
Your computer’s parallel port probably uses LPT1 and a
different IRQ setting. However, if it uses LPT2 or IRQ5, follow
the steps in this section to change the interface card’s jumper
settings.
