The connection is made as you see in your diagram... On pipsolar it works well and I don't have any problems. I switch to SMH and I can't get it to work

pipsolar have a lot of implemented protocols, i dont have all at the moment. without know what your device speaks i cant fix it. double check your wireing for twisted data lines and/or try to swap it
