Connecting the Scanner
Before you connect the scanner to your Macintosh, make sure that your sc anner as well as your

A terminator and a SCSI cable are supplied with your scanner.
Caution: For safety reasons, never use extension cables for power cords. Always m ake sure that
there is no more than one terminator in your SCSI chain and that it is p laced at the end of the
chain. Some SCSI devices have built-in terminators and must ther efore be placed at the end of
your SCSI chain. Please check the documentation of each of your SCSI devices if you are not sure
whether the device has a built-in terminator or not. Your Arcus 1200 h as no built-in terminator.
