About SCSI devices

The Horizon Ultra scanner 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.
Warning: If two SCSI devices have the same ID number, your system will
not work properly and you may damage your SCSI devices.

Changing the SCSI ID number

Before connecting the scanner to your computer, you must be aware
of the SCSI ID numbers already assigned. Your Horizon Ultra scanner
is preset to ID 2 and only needs to be changed if there is already
another device in your chain set to the same number.
1. Make sure your scanner is switched off and is disconnected
from your computer.
2. Decide on an unassigned SCSI ID number.
