SCSI devices
DuoScan is a Small Computer System Interface (SCSI) device. It communicates with your computer
by using the SCSI-2 standard. The SCSI communication standard allows you to have up to seven
peripheral devices connected to your computer.
Before connecting the SCSI devices you should always make sure that your computer and all SCSI
devices are switched off. If either the computer or any of the devices remains on, you could damage
the computer or the device.
A unique SCSI ID number is assigned to each device in the SCSI chain enabling your computer to
identify the device it wants to communicate with and the priority of each device.
Caution:
If two SCSI devices have the same ID number, your system will not work properly and you may
damage your SCSI devices.
To avoid crashes, never use extension cables for SCSI cables.
Installation for the Apple Macintosh
This section shows you how to set up your DuoScan with your Macintosh computer. You must first
choose and set a SCSI ID number, then connect the scanner to your Macintosh, and finally test the
connection.
