DOWNLOAD – This command modifies the ATX10
flash memory by replacing all configuration and profile
data with the contents of the files on the SD Memory
Module. In other words, the data is downloaded to the
ATX10 onboard flash from the SD Memory Module.
Figure 3 is a flow chart showing how the Memory
Module annunciations arise, and the user intervention
options that are available to get the Memory Module
synchronized and operating normally.

User SD Advisory
Menu
Note: During normal operation, if there is valid communication to an SD card, and there
are no advisory faults present (i.e. the user has handled them in the “User SD Menu”),
then the following will happen:
(1) When modifications to Config data occur on the ATX10, the modifications will also be
written to the memory module.
(2) When modifications to Profile data occur on the ATX10, the modifications will also be
written to the memory module.
If an SD advisory is being annunciated, Config and Profile updates to the memory module
will NOT happen. They will only be recorded in the ATX10 flash memory, and the SD
card’s Config and Profile files will remain unmodified and out of sync with the ATX10.
