There are two setup but only master 1 turns on? Thanks, Ben June 21, 2019 at 11:25 pm #61188 gt244Participant Ahh easy solution silly. Silly me did not have both the master ticked on the station options. Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
