twas the night before last and all was quiet in my street till I turned on my display to find my mega tree to be dark. the tree is run from DMX port on f16 v3 has worked fine for this month and several years previous . the receiver does not have the data indicator lights flashing when running show or test from f16. test button on receiver lights up tree fine. have tried several patch leads including one from new packet but no joy. I do have a expansion for f16 that i have never used, no idea how to set up in visualizer. any fault finding/work around ideas ?
