IMPORTANT
1. To set the setting terminals on NC models to short, apply voltage ranging
between -0.3 V and 0.8 V to the setting terminals externally. To set the
setting terminals on NC models to open, apply voltage ranging between
2.0 V and 5.5 V to the setting terminals from an external source.
2. Set the SCSI ID so that there are no duplicates between SCSI devices on
the same SCSI bus.
3. The priority of SCSI bus use in ARBITRATION phase is determined by
SCSI ID as follows:
7 > 6 > 5 > 4 > 3 > 2 > 1 > 0 > 15 > 14 > 13 > 12 > 11 > 10 > 9 > 8
