TYPICAL 2MM DRIVE ID PIN CONFIGURATION
NOTE: Applies to the DE100i-SW only.
Figure 7 illustrates a typical SCSI ID select connection to a drive with 2mm ID select pins. The
wires on the wire harness connect to the positive pin (or signal pins) on the disk drive. In some
cases, the drive manufacturer will label the signal pins as Pin 1, 3, 5, 7, (instead of 0, 1, 2, 3
as shown in Figure 7 below). Also, in some cases, the even-numbered Pins 2, 4, 6 are used
for Ground.
Attach the ID select cable to the drive using the 2mm connectors. Align the “ID0” pin with the
black wire. Attach the 1.25mm connector on the other end of the ID select cable to the 1.25mm
connector (J3B) provided on the signal distribution board, located inside the carrier. Refer to
the manufacturer’s documentation to disable termination on the drive.
(Pins vary on each drive model. See Drive
Manufacturer's Manual.)
