There is only one one switch that needs to be
configured before the scanner is connected to the
SCSI bus. The SCSI ID selection switch, located at
the back of the scanner close to the interface
connector, must be changed to a unique number.
Normally the host would take ID 7 with peripheral
devices taking IDs 0 through 6 although convention
requires that the scanner appears at ID 5. Check the
SCSI host documentation for further details.
