Installation guide

Notes for Figure 3a, 3b and 3c:
[1] Notes explaining the functions of the various jump-
ers 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 fac-
tory. "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" and "DC" models does not have
connector J1-auxiliary, but has a single 80 pin J1
connector having combined SCSI I/O and DC power
connector instead of the 68 pin SCSI I/O, 12 pin
auxiliary, and 4 pin DC power connectors that "W"
and "WD" models have. Included among the 80 J1
pins are the SCSI ID, Motor Start and Delayed
Motor Start select functions, and the remote BUSY
LED signal. Do not use J2 and J6 for these four
functions if the host uses the ones included in the 80
pin J1 connector.
[3] Drive ID may be established by installing jumper
plugs in one of the patterns shown in Figures 3a and
3b or by plugging onto J6 or J1-auxiliary a cable that
leads to an external ID selection circuit. Jumper
plugs on both J6 and J1 auxiliary, or J6 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.
