TP TP (Not applicable to "WC and 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
documentation). The Hawk 4 family
ST15230WD drive has differential I/O cir-
cuits 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.
TP Position A
On This horizontally positioned jumper across
the two TP positions nearest PCB edge,
connects terminator power from SCSI bus
I/O pin 26 to the drive's internal termina-
tors (for single-ended I/O only).
Off See above explanations for TP jumpers.
