Note: On TRB245, Data to Server is additional software that can be installed from the System → Package Manager page.

Data Senders

A Data Sender is an instance that gathers and periodically sends collected data to a specified server. The Data Senders list is empty by default so, in order to begin configuration you must add a new data sender first. To add a new data sender, click the 'Add' button.

After this you should be redirected to the newly added data sender's configuration page.
