Decagon Data Service

The Em50G uses "push" technology to upload measurement and log-
ger status data to the Decagon Data Service at regular daily intervals.
This type of push technology allows the Em50G to keep its cellular
hardware powered off for most of the time allowing long battery life.
The logger uses a unique cryptographic signature and checksum to
protect the integrity of the your data as it is transferred over the
cellular network and Internet as it is uploaded to the Decagon Data
Service.
The Em50G keeps track of the data successfully uploaded to the
Decagon Data Service. If your logger is unable transfer data during
one regularly scheduled session, the data is included in the next up-
load session.
Once stored in the Decagon Data Service, you can download your
measurement data from the Internet. Downloading data does not
remove it from the Data Service. Decagon safely stores your data for
download at any time.
