Appendix C Mass Storage Options
Isis does not restrict you to recording your data on just one kind of medium. You can record to
mass storage devices such a fixed hard disk, removable tape, or removable magneto-optical
disk.
C.1 SCSI Bus Configuration
All Isis optional mass storage devices, which are internal, are SCSI devices and thus require
the use of the Isis SCSI adapter card. Each drive and its adapter card has a unique ID (0 to 7)
on the SCSI bus. SCSI devices are daisy-chained with internal devices connected to the
adapter’s internal connector; external devices are connected to the adapter’s external
connector on the Isis back panel.
Each end of the SCSI bus must be terminated. The Isis system is delivered with the hard drive
terminated at the internal end of the SCSI bus. If additional external devices are connected to
Isis, the last daisy-chained external device must be terminated. If no external devices are
connected, the adapter will automatically terminate itself. The SCSI bus should be terminated
only at its extreme ends. Isis can access SCSI devices as shown in Table C-1.
Do not over-terminate the SCSI bus. Improper
termination can cause the SCSI adapter to fail!
