Selecting Single–Ended or Differential SCSI Bus Operation
You can independently configure each SCSI port on your VSA board for either
single-ended or differential operation by changing the orientation of a small
daughter board. The default is single-ended; you will need differential only if you
will use differential SCSI devices. Your SCSI ports might already be configured as
you need them, but if you must change one or both, this section explains how.
