Off On | Reserved. Default is no jumper installed. |
TP TP | (Not applicable to "WC/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 docu- |
| mentation). The "WD" drive has differential |
| I/O circuits which have no terminator circuits |
| on the drive. The "WC/DC" Model drives |
| have no provisions for terminators on the |
| drive and no provisions for terminator power |
| on the 80 pin I/O connector. |
On On | Drive supplies terminator power to itself (in- |
| ternal connection) and to I/O pin 26 of SCSI |
| bus. This is a legal jumper setting. |
Off | See above explanations for TP jumpers. |
TP Position A
On This horizontally positioned jumper across the two TP positions nearest PCB edge, connects terminator power from SCSI bus
