Okay, and how I could test that this FROM radio TO module connection is working in my setup? As I said I'm using that 470R resistor but I don't know so much about frsky or anything about telemetry that I could know how to test that?
But one thing. Kilrah you mentioned that this 47R is just for additional protection. So, I understand that it could be also left out. Am I correct? And if I am why it is for? Or what it is 'protecting' for?
