They all reset to the default ID#1 for me. Which can technically work, but I can't run an ABA because the rear A needs to have a direction change.
Aren’t both A’s set to the same default from the factory? If so, could you run them as an engine because the trailing unit defaults to run backwards out of the box?
Also I noticed if I flip the Program run switch back-and-forth many times the problem has not occurred for me for about the last 10 inches start up cycles
