SCSI Termination
The internal DAT 72 and DDS-4 drives do
not
provide SCSI termination. For this
reason, they should not be the last device on a SCSI chain. Two termination
examples are shown in Figure 12. If the drive is the only SCSI device, attach the
drive to the connector which is next to last on the SCSI chain and attach a multimode
terminator to the last connector in the chain.
