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

 

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 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 termi-

 

 

nators (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.
