I have two panels installed and one stopped working a while back.  I moved panel 2 to panel 1's location to test the panel to see if it still works and I receive a "No Controller Data" displayed.  I have made sure that the panels are using different addresses as suggested in a previous post.  At this point I am unsure as why the panel is displaying this error.  Thanks for help in advance!!
