I’m sorry, I just looked back at your link from the first page and they mentioned they were using a Mega, which should be 5V. I don’t know. I don’t have any other guesses. Do you have an oscilloscope you can put on the line to watch the communication between the sensor and CR1000? If so, can you share the results of sending a single command to the sensor via the CR1000 and the same command between the Mayfly and sensor?
