Configuring This Jukebox on a SCSI Bus
This jukebox is a “fast and narrow” SCSI device with the capability to
connect to either a narrow single-ended bus or a wide differential bus.
In the diagram below, note that the single-ended (50-line) bus is brought
directly onto the jukebox internal narrow bus. The differential interface
accepts a wide bus in its 68-pin connector, but only
uses the 50 data and
control lines
that comprise the “
narrow
” portion of the bus. The other 18
lines that provide the upper IDs and data of the wide bus are ignored.
Note that all lines of the wide bus pass through the two 68-pin
differential connectors. The wide bus is maintained as a wide bus.
The
single-ended
connectors are 50-pin and can accept only a narrow
bus. The
differential
ports use 68-pin connectors and can accept (and
pass through) a wide bus.
