THE ULTRA WIDE SCSI CONTROLLER
the upper half of the WIDE SCSI bus only. One of the Fast SCSI units needs to be connected
with activated termination to the other physical end of the Fast SCSI cable. Additional Fast
SCSI units with termination deactivated can be connected to free plugs of the Fast SCSI
cable.

Operation with only external SCSI units
The external connector is connected to the physical end of the WIDE SCSI cable. The
CYBERSTORM PPC SCSI has to be connected to one of the middle plugs of the SCSI
cable. An active terminator pack has to be connected to the other end of the cable.

Operation with external WIDE SCSI units and internal WIDE SCSI units
The external connector is connected to the physical end of the WIDE SCSI cable. As lang as
there are no external SCSI units attached, an external WIDE SCSI terminator plug has to be
connected to the external connector. The CYBERSTORM PPC SCSI has to be connected to
one of the middle plugs of the SCSI cable. The WIDE SCSI unit has to be connected at the
plug at the other end of the internal WIDE SCSI cable with termination activated. Additional
WIDE SCSI units with termination deactivated can be connected to free plugs of the WIDE
SCSI cable.
