Notes for Figure 3a, 3b and 3c:

[1]Notes explaining the functions of the various jump- ers on jumper header connectors J2, J5 and J6 are given below in left to right order of jumper position. The term "default" means as standard OEM units are configured when shipped from factory. "Off" means no jumper is installed; "On" means a jumper is installed. Off or On underlined is factory default condition.

[2]The PCB on "NC" models does not have connector J5, and has a single 80 pin combined SCSI I/O and DC power connector instead of the normal 50 pin SCSI I/O and 4 pin DC power connectors. Included among the 80 pins are the SCSI ID, Motor Start and Delayed Motor Start select functions, and the syn- chronous spindle master sync signal (SSP on J6) and the remote LED signals. Do not use J2 and J6 for these five functions if the host uses the ones included in the 80 pin connector.

[3]"ND" models do not have terminators on the drive PCB, so these jumpers are not applicable.
