Model-Specific SCSI Physical Characteristics
The sections which follow describe, for each of the drive models, those SCSI
characteristics which vary from model to model. These characteristics include:
•
Termination
•
Cable requirements
•
Connector requirements
•
Connector Pin assignments
•
Interface Timing requirements
