Color Control GX manual

Since version 1.40, dealing with an absent or intermittent internet connection has changed. Data is
sent out via the Internet if it's available, and will fall back to non-volatile storage when there is a
(temporary) Internet outage. The built-in non-volatile storage can contain 48 hours worth of data. To
extend this period, one can insert an microSD card or USB stick, and the CCGX will automatically
transfer any data that may reside on the internal storage to it, and will start using this external
memory as backlog buffer. You can see that it's active in the settings menu:
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) 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.
