When using this external memory, it will still make use of an active internet connection to send its backlog. That means that even with months worth of backlog, once the CCGX re-acquires an Internet
connection, all of the backlog is sent out. And because of an enhanced algorithm, this takes considerably less time and traffic than before.
When a CCGX is permanently without Internet, one can choose to upload the backlog buffer manually. The first step is to use the GUI (Graphical User Interface) (Graphical User Interface) to eject the
storage (don't just remove the SD-card/USB-stick). The storage device can then be removed from the CCGX and inserted into a computer or laptop, the data file on it can be uploaded on the VRM Portal
with the 'Upload CCGX File' option:
It's important to know that when the microSD card or USB stick is re-inserted, the existing buffer - including its data - is used again. This allows for removing the microSD card temporarily for whatever
reason, but this also means that when the data file has been uploaded to VRM, it needs to be renamed or cleared from the microSD card / USB stick before re-inserting, otherwise the data will
be transmitted again, sooner or later, on-line or off-line.
Because of the aforementioned improvement in sending of backlog data, the data logging is also highly resillient to bad internet connections. Lines of up to 70% permenant packet loss are still sufficient to
get the data out, albeit somewhat delayed.
With a log interval of once per minute, the required storage space roughly amounts to about 25 MB (Megabyte) per month, depending on the number of connected products. So with a 1 GB (Gigabyte)
microSD card, you can store about 3 years of backlog. In other words, any microSD card or USB stick should be sufficient to store the 6 months of data which VRM retains.
When the storage device is full, no more data will be logged. This is due to the nature of Sqlite files. Removing data from the Sqlite database doesn't free-up usable disk space; and because of internal
fragmentation, it doesn't guarantee more data storage.
If both a microSD card and a USB flash drive are connected to the CCGX, then data is logged to the one that was inserted first. If one is removed, the CCGX will not try to write to the other, but will
create an internal backlog buffer until a new storage medium is inserted when it will use that storage medium.
MicroSD cards or USB flash drives must be formatted as FAT12, FAT16 or FAT32 file systems - and not exFAT or NTFS.
SD and SDHC type microSD cards of 32 GB (Gigabyte) capacity and smaller are sold containing FAT12, FAT16 or FAT32. They can be used without a problem, unless they are subsequently re-
formatted to a different file system.
SDXC type microSD cards which have greater than 32 GB (Gigabyte) capacity are often formatted with exFAT, and therefore cannot be used with the CCGX without reformatting and possibly
re-partitioning.

'Overruled by remote' setting in VEConfigure
This chapter explains the implications of enabling or disabling user control of the input current-limiter setting, as seen here in the menu:
