I was able to use the power iso in i2c directly connected to the relay box and also using the hub. only issue was call/response out of sync. the difference between running with or without a hub is the matter of supplying the DO circuit power from an external source vs taking the power from RA. Behin...

Power iso seems to work well, but I ended up putting an Arduino uno in between so I don't have to deal with call/response out of sync as it has affected many things in the program and I did not have the patience to fine tune it. so I am reading values in continuous UART mode to an Arduino and callin...

Thanks Jon for your reply. I have purchased the power isolator circuit from Atlas Scientific also and using it, I hope this will eliminate the interference. How are you supplying power to the DO circuit? Can you post your code for the DO libraries you created so I can compare with mine? maybe we can...

Hi, First post here. I have been playing with DO probe from Atlas Scientific and RA. It was not hard to get it to read when connecting it directly to the relay box, however I am almost out of ideas on how to get it working when connected to the hub, and what would possibly you have to change in the ...
