Jim,
TIU gives one blink red light on power up. Remote Addr =1, TMCC ADDR = 59, remote says "TIU = 2 ADDED" That's pretty strange. How do I change that to say TIU = 1 ADDED?
You need to be more specific. Where does this happen? In the remote or the app? Exactly what sequence of events causes exactly what messages?
Are you using the very latest DCS App release? Based on your previous information, I don't think so. If you aren't you must update your DCS App before we go any further.
