Data compression (switches 1 and 2)
If switch 1 is ON (the default setting), hardware data
compression is enabled when the drive is powered on. If
switch 1 is OFF, hardware data compression is disabled at
power-on.
If dip switch 2 is ON (the default setting) then SCSI commands
can be used to enable or disable hardware data compression. To
prevent hardware data compression from being enabled or
disabled by SCSI commands, set dip switch 2 to OFF.
Media-recognition system (switch 3)
The media-recognition system allows the drive to determine
whether a given tape cartridge conforms to the DDS tape
standard. Use of non-DDS media may appear to give
switches. Changes take effect when the drive restarts.
