TP TP (Not applicable to "WC" model drives)
Off Off No terminator power is connected to drive termi-
nators 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 termi-
nator (see system documentation). The "WD"
drive has 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.
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 terminators (for single-ended I/O
only).
Off See above explanations for TP jumpers.
