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

[1]Notes explaining the functions of the various jumpers on jumper header connectors J2, J1-auxiliary 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 "WC" models does not have connector J1- auxiliary, but has a single 80 pin combined SCSI I/O and DC power connector instead of the 68 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 synchronous spindle master sync signal 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]Drive ID may be established by installing jumper plugs in one of the patterns shown in Figures 3a, 3b and 3c, or by plugging onto J6 or J1-auxiliary a cable that leads to an external ID selection circuit. Both jumper plugs and an external ID selection source should not be used. See [4] for other functions of these two headers that are time-shared with the drive ID function.
