SS
Off On Reserved. Default is no jumper installed.
TP TP (Not applicable to "WC/DC" model drives)
Off Off No terminator power is connected to drive
terminators or SCSI bus I/O pin 26.
On Off Drive supplies its own terminator power only.
Jumper on this position is factory default.
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 terminator (see system docu-
mentation). The "WD" drive has differential
I/O circuits which have no terminator circuits
on the drive. The "WC/DC" Model drives
have no provisions for terminators on the
drive and no provisions for terminator power
on the 80 pin I/O connector.
On On Drive supplies terminator power to itself (in-
ternal connection) and to I/O pin 26 of SCSI
bus. This is a legal jumper setting.
Off See above explanations for TP jumpers.
TP Position A
On This horizontally positioned jumper across
the two TP positions nearest PCB edge,
connects terminator power from SCSI bus
