6. A message displays information for the
FUTURE SETTINGS. This
allows you to input the addressing assignment method and AL_PA
that you want to use at a later time, without affecting your current
connection. (Changes to the FUTURE SETTINGS will take effect on
the next power up or board reset.)
TIP For multi-level libraries, settings can be changed simultaneously for each
level of the library by changing the
FUTURE SETTINGS and then
power-cycling the library.
• The default addressing is hard addressing with auto-select
enabled. Hard addressing allows you to set and maintain a fixed
address, but may result in address conflicts. Soft addressing looks
for an unused address on every power cycle, so the address might
change.
NOTE Since AL_PAs can change with soft addressing, some backup software
applications may have difficulty locating the library in this mode. Check
the backup software documentation to ensure soft addressing is
supported before selecting this mode.
