Notes for Figure 2a, 2b and 2c:
[1] Notes explaining the functions of the various
jumpers 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 and the re-
mote LED signals. Do not use J2 and J6 for these
five functions if the host uses the ones included in
the 80 pin connector.
