About SCSI

sure to turn it on. For details on attaching an active
terminator, refer to the owners manual of your SCSI device.
* On some SCSI devices, the terminator switch is always on
(i.e., the terminator is always active). Attach such devices at
the end of the SCSI chain.
* Do not “double” terminators. For example, do not attach an
external terminator to a SCSI device that has an internal
terminator.
About SCSI ID Numbers
SCSI devices are distinguished by a SCSI ID number (07).
Thus, when connecting two or more SCSI devices, you must
set the SCSI ID number of each connected SCSI device so that
they do not conflict. If any SCSI ID numbers conflict, the XV-
5080 will not detect the SCSI devices correctly. When the XV-
5080 is shipped, its SCSI ID number is set to 7. Set the SCSI
ID numbers of the connected SCSI devices to a setting other
than 7.
fig.scsi-003.e
If it is not possible to set the SCSI ID number of a connected
SCSI device to something other than 7, you will have to
change the SCSI ID number of the XV-5080. To do so, rotate
the ID knob located on the rear panel.
Making Connections
When you understand the material given in What you need
to know before making connections, refer to the connection
examples and connect your SCSI device accordingly.
Be sure to turn off the power of all devices before you do any
of the following three things.
Connect/disconnect a SCSI cable
Turn a terminator on/off
Set a SCSI ID number
* For the procedure of turning on the power, refer to p. 12.
