Fixed #1 is working as expected, but #2 has power but does not communicate with controller. Engine starts up, makes sounds, does not respond to controller, and will not move.
I opened the TIU and the fuses look good as I expected since there is power. Is there setup I have to do to get #2 working properly?

Did you check to see if it's configured for DCS operation? That would be my first check.
It's also possible for the DCS signal to fail on one or more channels, I've had that happen. In that case, it's a trip to MTH for repair.
Is there setup I have to do to get #2 working properly?
Yes, there is.
You must ensure that the TIU itself is getting power by either:
This and a whole lot more is all in "The DCS O Gauge Companion 2nd Edition", now available for purchase as an eBook or a printed book from MTH's web store site! Click on the link below to go to MTH's web page for the book!

I have the book.Where are the setup instructions? I didn't have to do anything for Fixed #1.

If the TIU channel #1 is working with DCS control, I think you've covered what Barry is talking about. If you didn't have the TIU logic powered, you wouldn't have DCS on channel #1.
Steve,

There are no "setup instructions". TIU Fixed Channel #1 will always have a DCS signal as long as the TIU has power, which it's currently getting whenever Fixed Channel #1 IN has power. All other channels need for the TIU itself to be getting power.
For the time being, just turn on power to both Fixed #1 and #2 in order to operate DCS on Fixed Channel #2.
Then, look at pages 92-93 under Part V - Advanced Features and Functions, 1. External TIU Power regarding methods for providing power for the TIU itself.
