Tiu

Did you also update the remote?

My remote would not update, so I borrowed one that has 6.10 on it, but it still doesn’t see a engine on the track. I have my legacy running through the tiu and it recognizes the locomotive

When you power up the TIU, are you getting a single flash from the LED near the round hole in the top grill? 

If so, I suggest trying to see if the remote is even seeing the TIU.

• Menu
• System
• TIU Setup
• TIU Version

If you get an error there, you aren't seeing the TIU. 

When I turned on the tiu I did get a single flash but when I did what you said to do on the remote, the remote said that the tiu was version 6.10

OK, if that's the only TIU that's powered up, you're talking to the TIU.

Next.

• Menu
• System
• DCS Setup
• Press the AON hotkey

Try adding the engine on your test track after doing that.

It still says no engine to add!

Did you try all the channels?

Yes

Running out of ideas. 

Well thanks anyway

One last gasp.  Try doing the update again.  We recently had a person here that did the firmware upgrade and everything stopped working.  Did another one and all was well.

That worked. Thank you so much!

Wow, that was my last gasp, but I figured it was worth a shot.
