Yes, I did get the Keller CTD. We had the budget and I was able to get an extra Hydros21 to deploy while figure out the Keller CTD. It took me a while to get the parts for the Modbus Wing shield and then build it, but I finally got them and had time to do it… so now I am in the thick of it.

I did follow instructions from the post you mentioned. I have begun doing what you suggest as well… parsing out the raw requests and responses to see what is happening. This may take me quite a while to figure out since I am new to all of this.

I’ll probably post some follow-up questions for the community once I can unravel some of the information that I am getting back from the sensor.

Thanks,
Dan
