Connecting the Scanner Using the SCSI
Interface
For instructions on connecting the scanner to your computer
using the SCSI interface, read this section.
®
Note for Macintosh
You need to install the scanner software before connecting the scanner
to your computer. Follow the instructions in Chapter 3 to install your
software, then connect your scanner as described in this chapter.
For PC users:
Unless your PC already has a SCSI board installed, you need to
install one, along with SCSI driver software. Install the SCSI board
according to the directions included with it. Also see “Installing
a SCSI interface board” on page 2-8.
Note:
You will also need to install the SCSI driver that is normally included
with Windows (see your Windows documentation for instructions), or
the driver described in your SCSI board installation documentation.
If your PC has a SCSI board up and running, connect the scanner
as described in “Connecting the scanner” on page 2-13.

For Macintosh users:
Your Macintosh may or may not have SCSI ports, depending on
which model you own. See the next section if you need to install
a SCSI board in your Macintosh. If your Macintosh already has a
SCSI port, install the scanner software as described in Chapter 3,
then connect the scanner to your Macintosh as described in
“Connecting the scanner” on page 2-13.
Note:
The latest driver may be available for download from the Web site of the
SCSI board manufacturer.
Setting Up the Scanner
2-7
Installing a SCSI interface board
Follow the instructions in this section to install a SCSI board and
SCSI software in your computer. You should do this before
installing the scanner driver and software applications.
If you already have a SCSI board installed in your PC or
Macintosh, go to the next section.
Note:
For additional information, see the installation guide that comes with
your SCSI board.
1.Turn off the computer and any peripheral devices. Unplug
any power cords, then disconnect all cables from your
computer.
2.Remove the cover from your computer.
Caution:
c
Static electricity can damage electronic components.
Discharge static electricity by touching the metal frame of
your computer before handling the interface board or any of
the computer’s circuit boards.
3.Insert the interface board into an appropriate expansion slot,
then secure it with the retaining screw.
4.Replace the computer cover and reconnect all cables.

Understanding SCSI connections
Read this section to determine how to set up your SCSI devices
and whether you need any optional SCSI cables.
Daisy chain
The SCSI interface allows you to connect up to seven devices (such
as a scanner, hard disk, CD-ROM, and so on) to the computer, in
what is called a “daisy chain” arrangement. Only the first SCSI
device in a daisy chain is connected to the computer; each of the
other devices is connected to another SCSI device.
SCSI cables
You may need to purchase SCSI cables before setting up your SCSI
daisy chain. Be sure the SCSI cable connectors are suitable for your
hardware, depending on the maker of your SCSI device and SCSI
interface board.
SCSI ID and terminator
2
Each device has a SCSI ID number: the computer is usually
number 7, and each of the other devices must have a different
number between 0 and 6. Also, the first device and the last device
in the chain (not including the computer) must have a terminator.
No other device can have a terminator, or if a terminator does
exist, it must be turned off or removed.
Setting Up the Scanner
2-9
Setting the SCSI ID number
The scanner's SCSI ID switch is set to number 2 at the factory.
SCSI ID rotary switch
If you add the scanner to a system in which one of your SCSI
devices already has a SCSI ID of 2, change the ID number to an
unused number using the rotary switch. See the table below as a
guide.
