SDXC type microSD cards which have greater than 32 GB capacity are often formatted with
exFAT, and therefore cannot be used with the CCGX without reformatting and possibly re-
partitioning.
Manually transferring datalogs to VRM
For devices permanently without Internet, it is possible to take the data out, and then upload it
manually from a laptop.
1. go to Settings → VRM Portal, and click Eject the storage. Make sure to never just remove
the SD-card/USB-stick, this can lead to corruption and data loss.
2. now, remove the storage device and insert it into a computer or laptop that is connected to the
internet.
3. open a webbrowser, and navigate to the VRM Portal.
4. Login, and then click the 'Upload CCGX File' option, and follow instructions:
5. Remove the file from the storage device, and then it re-insert it into the GX Device. Note that
uploading the same data twice does not cause any problems; but still it is better not to do that.
With a log interval of once per minute, the required storage space roughly amounts to about 25 MB
per month, depending on the number of connected products. So with a 1 GB 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.
If multiple storage devices are inserted, the GX device will store the data on the one inserted first.
When that is removed, it will not use the other one. Instead, it will create an internal backlog buffer.
Only inserting a new one will make it switch to using external storage again.
Network watchdog: auto-reboot
This feature, disabled by default, makes the GX device automatically reboot itself in case it has not
been able to connect to the VRM Portal.
