Something weird happened a few weeks back. When I turn power on to the TIU with Fixed in 1 the WIFI has no problem finding the engines. When I turn on power (same transformer, New Lionel) I get "can't find TIU". If I use my old handheld it has no problem finding the engines (as long as I don't refresh, I can run engines on Fixed 1 using WIFI and Fixed 2 using the handheld). Same thing with the tracks associated with the variable voltage inputs. If there is no power to them it doesn't cause the error, but if there is I get the same error.
I've removed all outputs from the TIU except for Fixed 1, and repeated the process and still get the same results. Any time there is power to Fixed 2 or Variable 1 &/or2 I get "can't find TIU". Am I missing something?
PS - OGR Forum help with my TMCC Legacy was fantastic! Lionel fixed it free and got it back before Christmas!
