Connect Sensor
If you purchased the SDI-12 Sensor and SDI-12 Node from Verdi as a kit, there will be a cable with a connector pre-installed on the sensor and the node to make wiring simple. Plug the 3-pin cable of the Verdi SDI-12 RTU to the 3-pin cable of the sensor. Screw the threaded parts together to create a secure and waterproof connection.
For all other installations, please refer to the wiring diagrams: https://docs.verdi.ag/docs/verdi-sdi-12-telemetry-node-wiring-diagrams
