Daisy Chain
The SCSI interface allows you to connect up to seven devices (such
as a scanner, hard drive, CD-ROM, and so on) to the computer, in
wha t is c a ll e d a “ d a is y c ha i n ” a r r an g e me n t . O n ly t h e fi r st S C SI d e vi c e
in a daisy chain is connected to the computer; each of the other
devices is connected to another SCSI device.
Note:
To work with a scanner in wide SCSI, the scanner must be connected to
the wide SCSI Host Adapter via a 68-pin SCSI cable. If narrow SCSI
devices exist between the SCSI host adapter and the scanner, the scanner
works only in the narrow SCSI mode. In this case, you need to set the
select switch to N (narrow).
SCSI Cables
You may need to purchase SCSI cables before setting up your SCSI
daisy chain. The scanner has two SCSI connectors: one is for a
wide 68-pin SCSI cable and the other for a n arrow 50-pin SCSI
cable. Be sure the SCSI cable connectors are suitable for your
hardware, according to the maker of your SCSI device and SCSI
interface board.
SCSI ID and terminator
Each device has a SCSI ID number: the computer is usually set to
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 a terminator.
No other device can have a terminator, or if a terminator does
exist, it must be turned off or removed.
