Sorry for the confusion, in a nutshell…
1.- I created the PID 1 in pac control with input 1 and output 1, but noticed unrelated input 2 NAN immediately after download and strat started, input 2 is not related to PID 1 at all.
2.- I pac control deleted the PID 1, input 2 came back immediately back as good signal, yet the output of now gone PID 1 was been controlled by something, Groov manage showed PID 1 there, up and running.
3.- I pac control created again PID 1, same name, same i/o, no issues now, PID1 is working, input 2 is working.
