Model numbers that end in "ND" have differential I/O
circuits and these drives and some "NC" model drives
have no provisions for terminators on the drive PCB.
The system manufacturer must provide some external
means of I/O line termination. The "ND" model drives
can provide power for external terminators if the TP
jumper is installed on the last position on the right end
of J2. See Figure 3a.
Read/Write head auto-park
Seagate disc drives described herein mentioned in this
drive park the heads automatically at power off. This
feature requires no operator intervention.
Optional parity bit enable
Some systems require parity bit checking. Consult the
system documentation for the specific requirements.
See figure 3a for location of Parity Bit enable jumper.
Jumper-installed enables parity reporting by the SCSI
bus.
Write precompensation and reduced write current
Not required on Seagate SCSI Interface drives covered
by this manual.
