I am almost never any help in these kinds of threads . . . but my temptation would be to try to set the address to 1110 instead of 0111. I don't know how various systems handle leading zeros.

Carry on.

I checked like you suggested that the loco was still responding to address 3, which it did. I then set CV29 to 38.

You did say that you have a ProdigyAdvance?  According to the user manual I found on line, https://tonystrains.com/download/mrc-advance-man.pdf, for addresses 1 to 127 CV29 should be 2, and for addresses 128 to 9999 should be 34.  See page 2-8 of the instruction.

111 or 0111 appear to be short addresses so far as the Prodigy is concerned.  Try setting CV29 to 2 and see what happens.  If that works, then we'll all say RT**M.

 

Edit:  Oh, and to make Rich and a bunch of us others happy, please set CV 19 to zero before you do anything else. It will only take a second.

1110 on any system would be long address 1110. So it's an option for the OP where the cab number is 111.

AFAIK, only NCE bothers with leading 0's, which is how it distinguishes short address 111 from long address 111. Most others use a rigid demarcation where address in one range are always short and address in another range are always long, so all you do is key in the address you want to select and the system takes care of it. I'm beginning to suspect MRC is one of these, despite how in much of their design they copied NCE.

I have tried to set CV19 to 0. As others pointed out, if the loco is responding at this very moment to address 3, then CV19 has to be 0, no?

As for trying 0111 or 1110, I have initially tried address 1234 and it didn't work. When I tried "0111", it was at the "Adr" prompt when programming on the main track. When you hit "Enter" on programming, the first thing the Prodigy asks is the loco address. I usually just press "Enter". Then, the second prompt is "Adr". That's what I used to set my 2nd Bachmann that I had been unable to program to address 974. I just entered "974" there and it seems that the Prodigy did take care of setting CV29, CV17 and CV18 because now this Bachmann is perfectly responding to 974. That's when I tried the same thing with address "0111" on the Athearn. I didn't try to change CVs values, I just entered "111" when prompted for the "Adr". The manual for the Prodigy doesn't explain what this "Adr" is but I am now assuming it is prompting for a new address for the loco. Since the first prompt is "Loco", I'm guessing it wants to know which loco you want to program. Then, "Adr" is showing which seems to be the new address. I will write to MRC to ask them to clarify.

The problem is that the only thing the Athearn is taking is a reset of the decoder.

Did you try setting CV29 to 2 as I mentioned above for address 111?

EDIT: And when it asks for the loco address, re-enter 111 rather than just pushing the enter key.

 You DIDN'T try 1234 - you used the wrong programming sequence which is why that didn't work.

 From what maxman found, 111 will never work as a long address. You do not set anythign into CV17 or 18 for this. But here's the rub, you can't just change CV1 when using POM.  If the loco is currently address 3 and working, first you have to change it to something else, like 1234, long address. THEN you can repeat the process but instead of setting CV17 and 18, you set CV1 to 111 and then set CV29 to 2.

If it's running now on 3, do this, EXACTLY.

Enter POM mode.

Set CV17 = 196

Set CV18 = 210

Set CV29 = 38

Now go back and select loco 1234 - it should run. With 1234 selected, go bac into POM mode

Set CV1 = 111

Set CV29 = 2

Now it won't be working again. Go back and select loco 111 - should work.

Who knows with MRC equipment. With the NCE PH-Pro, 3 is a valid consist number, so on my PH-Pro, 3 can be a short address or a consist (CV19=3).

Or, 1111, for that matter.

I wonder what happened with this problem.

Yea, I've been wondering too, as I like to follow along with these threads, and see what the "fix" ends up being.

I know nothing about the MRC system, as I'm still learning my 13 year old Digitrax, SEB.

I haven't had the time to try the latest suggestions but I will this weekend and will keep you posted.

I will make this offer to nemesys. Box up the Athearn Genesis FP7 and mail it to me. Assuming that there is nothing wrong with the decoder, I will program it to an appropriate long address and send it back to him. This issue has been lingering since April 4th.

 I am convinced the problem is simply that MRC behaves more like my Digitrax, addresses 1-127 are always short. I can program a decoder to have a long address 111, but then I won't be able to control it until I change the address.
