Cloud Connectors must have a connection to DT Cloud servers for the sensor system to operate. The connection can be by cellular or by Ethernet.
Cloud Connectors with a built-in cellular modem can connect to the DT Cloud through the cellular network without any configuration. If you plan to use cellular, make sure that the planned installation location has sufficient cellular connectivity.
All Cloud Connectors can connect to the DT Cloud through its Ethernet port. If you plan to use this option, then make sure to configure your firewall according to the information in the Firewall setup for Cloud Connectors article.
