Overview

The NexSens RTU-C Remote Telemetry Unit acts as the main cellular or iridium telemetry device for X2 data loggers while allowing for fallback to the internal data logger telemetry. RTU-C units are watertight and able to operate in extreme environments. The internal settings allow users to adjust transmission settings via the embedded Wi-Fi. The RTU-C can be powered by any 12VDC source, including a direct connection with a NexSens CB-series buoy battery or SP-series power pack. The RTU-C accepts sensor measurements from NexSens X2 data loggers and can transmit this information to the WQData LIVE cloud data center.
