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.
