About SCSI

sure to turn it on. For details on attaching an active terminator, refer to the owner’s 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 (0–7). 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.”

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.
