PX-R820T OPERATION MANUAL
19
REMEMBER: Only the last SCSI peripheral in a daisy chain should have
termination enabled. If you have any SCSI devices chained after
your PlexWriter, you must disable or turn OFF the PlexWriter’s
termination using the following instructions:
Internal Termination
The PlexWriter internal drive is shipped from the factory with its termination
enabled (ON).
To disable termination, remove the jumper from the termination pins on the
back panel of your drive. Refer to the diagrams on page 13 for the location of
the termination pins (labeled “Term”). They are the second set of pins from the
left.
If your drive is already installed in your computer, be sure to turn off your
computer before removing (or reinstalling) the jumpers. We recommend that
you retain the jumpers so you can reinsert them onto the termination pins if
you later need to turn the drive’s termination ON.
External Termination
The PlexWriter external drive is shipped from the factory with its termination
turned ON.
To turn the termination OFF, first turn off the drive’s power, then change the
second DIP switch on the rear panel of the drive to the OFF position. Refer to
the pictures on page 16 for the location of the termination switch (labeled
“Term”). It is the second of the five switches.
