SCSI Setup
For some PCs, you must first install a SCSI board in your
computer. All Macintosh computers have built-in SCSI ports;
you do not need to install a SCSI board. Follow the directions
below to connect the scanner to your PC or Macintosh.
SCSI connections
The SCSI interface allows you to connect up to eight devices,
including the computer, in a “daisy chain” arrangement. Only
the first SCSI device in a daisy chain is connected to the
computer; each of the other devices is connected to the
previous device.
Each device has a SCSI ID number: the computer is usually
number 7, and each of the other devices must have a different
number between 0 and 6. Also, the first device and the last
device in the chain (not including the computer) must have
terminators. If any other devices in the chain have terminators,
the terminators must be turned off. The scanner has two 50-pin
SCSI connectors and a built-in terminator that you can turn on
or off.
Setting the SCSI ID number
The factory-set SCSI ID number of the scanner is 2. The
computer’s SCSI ID number is usually 7. If one of the SCSI
devices in your system already has the SCSI ID number 2,
change the scanner’s SCSI ID number to an unused number as
described on the next page.
