Of course. I would begin with a track read, the remote would search for the active TIU until found. Next I would try to add an engine. See attached images for sequence.
- For TIU's 2 to 4 the remote would say, "LOOKING FOR ENGINE..."
- After 45 seconds to a minute the screen shows, "OUT OF RF RANGE"
- 15 seconds or more later, the screen would show that the engine was added.
- I could start the engine & it would function normally.
This would happen every time. Once I would change the address back to TIU 1, no more "OUT OF RF RANGE" messages with all 4 TIU's. This would be on the test track or on my layout. No signal issues with any TIU addressed as TIU 1.
I'm happy with my results and observations. No point in having any TIU addressed other than TIU 1 if I never have more than one being used at the same time.
