SCSI Identification

Make sure that the drive unit has the proper SCSI-ID before it is connected to a
computer system.

Refer to manuals for host computer and application software to obtain the correct
ID. For correct mounting of ID-jumpers at the rear of the drive, please refer to
Figure 3 and Table 1.

External drives have a thumb-wheel switch to set the SCSI-ID (see Figure 6).
