PE
On Parity checking and parity error reporting by the
drive is enabled.
Off Drive does not report result of parity checking to
host. Default is a PE jumper installed.
SS
Off/On Reserved. Default is no jumper installed.
TP TP
Off Off No terminator power is connected to drive termina-
tors or SCSI bus I/O pin 26.
On Off Drive supplies its own terminator power only. Jumper
on this position is factory default for "N" models
only.
Off On Drive supplies power to I/O pin 26 of SCSI bus;
none to internal terminators. When drives have
differential I/O circuits, a jumper on the right TP
position may be needed to power external termina-
tors (see system documentation). The "ND" model
drives have differential I/O circuits which have no
terminator circuits on the drive.
On On Drive supplies terminator power to itself (internal
connection) and to I/O pin 26 of SCSI bus. This is
a legal jumper setting.
