Hi Folks,



I've got an L level TIU that I've been using for years with an original 1.0 wifi unit but recently when I fired it up the wifi unit does not see the TIU.  At least I get no light and no connectivity to the track via the app.   I've got a 1000W mth power supply going into fixed in a and fixed out 1 to the track.

How do I diagnose the problem?

It is a standard USB cable but one end is USB B plug.  You might have one around.  You usually find them on computer peripheral devices like a printer.  It is unlikely that the cable just died.  Unplug both ends and plug it back in.  Since everything was working and suddenly doesn’t work, I would be looking at my software.  Shut them both down then start the TIU then start the Wi-Fi.  Look at system setting and see if it is trying to connect to your TIU.

To get to system setting, from the Home screen tap "more" on the bottom right.  Now select Advanced Features.

I tried swapping with another usb cord and like you thought its not the issue.   When I went to the app and went to tiu settings is just says no active tiu found.



Is there a fuse on the usb port on the tiu that might have blown?

Wondering if you tried to reset the WIU. Did you recently try to add a new engine to the system right before the system started malfunctioning?

No the last time I used it was on my HO track.   I put it away for about 4 months and tried it on my O gauge track.  Different power supplies obviously but nothing else was different.



Is there any way to test the TIU independently?  I do have one of the old traditional 750s controllers but never hooked it up to the tiu if its even possible.
