• Terminator Settings
The terminator marks the last device in a daisy chain. It tells the computer that "this is the
last device". There are two types of terminator: a separate device that is attached to a SCSI
device or an On/Off switch built into the SCSI device. This scanner has a built-in terminator.
For a daisy chain to operate correctly, the terminator must be set to On for the last SCSI
device , and Off for all other SCSI devices. A typical daisy chain is shown below.
