Macs are surprisingly tolerant to wrong SCSI cabling. If the scanner has
or needs a terminator, should be metioned in the manual. Perhaps you
find some switch labeled "terminator on/off" near the SCSI ID selector

You should also make sure that the other end of the cable is properly
terminated; perhaps the adapter's bios or the adapter driver allow to
select the transfer rate. 5 MB/s should be enough for the scanner.
