Jumper
Installation Jumper Function Description
TE (Applies only to “N” and “W” models)
On
With the jumper installed, the On-board (non-removable) terminator circuits are enabled
(connected to the I/O lines). Default is jumper installed.
Off Terminator circuits not connected to I/O lines.
DS ME
Off Off Spindle starts immediately after power up - Default setting.
Off On Drive spindle does not start until Start Unit command received from host.
On Off Spindle Startup is delayed by SCSI ID times 12 seconds after power is applied, i.e., drive 0
spindle starts immediately when DC power connected, drive 1 starts after 12 second delay,
drive 2 starts after 24 second delay, etc.
On On Drive spindle starts when Start Unit command received from host. Delayed start feature is
overridden and does not apply when ME jumper is installed.
WP
On Entire drive is write protected.
Off
Drive is not write protected. Default is no WP jumper installed.
PD
On Parity checking and parity error reporting by the drive is disabled.
Off
Drive checks for parity and reports result of parity checking to host.
Default is PD jumper not installed.
SS
Off
Reserved jumper position. Default is no jumper installed.
TP TP (Does not apply to “WC” model)
Off Off No terminator power is connected to drive terminators or SCSI bus I/O cable [1].
On
Off Drive supplies its own terminator power only. Jumper on this position is factory default.
Off On Drive supplies power to SCSI bus I/O cable [1]; none to internal terminators.
On On Drive supplies terminator power to itself (internal connection) and to SCSI bus I/O cable [1] .
This is a legal jumper setting.
TP Position A (Does not apply to “WC” model)
On This horizontally positioned jumper across the two TP positions nearest PCB edge, connects
terminator power from SCSI bus I/O cable [1] to the drive’s internal terminators (for single-
ended I/O only).
Off See above explanations for TP
