Operation with external WIDE SCSI units and internal Fast SCSI units
The external connector is connected to the physical end of the WIDE SCSI cable. As long 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 other end of the WIDE SCSI cable is
connected to a Fast SCSI cable using an adaptor WIDE->Fast. The adaptor used needs to
terminate 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.
