The ER-102 stores snapshots and loads firmware upgrades via its microSD card slot.
If it doesn't already exist, the ER-102 will create the following files and directory
structure on your memory card:
ER-102/
FIRMWARE/
SNAPSHOT/
TABLES/
CONFIG.INI
METAINFO.BIN
The FIRMWARE directory is where the ER-102 will look for firmware binaries. The
SNAPSHOT directory is where the ER-102 saves snapshots (and their revisions). The
ER-102 loads the user voltage tables from the TABLES directory. The CONFIG.INI file
is the global configuration file (see the section on Configuration Files). Lastly, the
METAINFO.BIN file is used by the ER-102 to keep track of some internal state like the
last snapshot loaded and what version of the ER-102 firmware last accessed this SD
card.
Tip:
Loading and saving snapshots will only work while the STORAGE switch is set to
USER. ADMIN is used only for firmware updates at the moment.
Warning:
Since the ER-102 does not have the battery-backup necessary for keeping
track of the date and time, timestamps of those files written or modified by the ER-
102 are not going to be very meaningful.
