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 no PE jumper installed. |
|
TE |
| (Applies to "N" and some "NC" models only) | |
On |
| With the jumper installed, the | |
|
| removable) terminator circuits are enabled (con- | |
|
| nected to the I/O lines). Default is jumper in- | |
|
| stalled. |
|
Off |
| Terminator circuits not connected to I/O lines. | |
TP | TP | (Not used on "NC" drives not having U5 on | |
|
| PCB) |
|
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- | |
|
| 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. |
