Typical 2mm Drive ID Pin Configuration
Note: Applies to the DE75i-SW160 only.
Figure 3: Typical ID Select Connections (2mm Drive Pins)
Figure above 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 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.
Selecting the Unit ID Number
Use the alignment tool (provided) to select the ID number of the disk drive.
NOTE: The lock on the Data Express serves as a power switch. It
must be engaged (turned counterclockwise) for the Data Express
to power up and function properly.
