I don't know if this is applicable or not. If you put
If I remember correctly the decoders took way too long to respond back to the command station, so the response timed out.
If you see the locomotive lurch a little when you program a CV, you know it took.
I had the same problem with my MRC sound decoders on my old set 100 Lenz. It's a well known problem.

I don't think those decoders have any readback. Also they are register-mode only, they only support a limited set of 'registers' (CVs), and will not work ok paged or direct mode.

...really! It's better to get a reliable decoder for those passenger cars and cabooses. Otherwise, you'll be opening them up again and again.

I need some help to program some old decoders ...
More than 10 years ago, I replaced all of my MRC 305 decoders with more up-to-date ones. Now, I want to use those old decoders as function-only decoders in my passenger cars and cabooses. My problem is that my Lenz system (Set 100 w/ Version 3.6 firmware) won't recognize ANY of them on the program track. Each time, I get an Error 2, i.e. no decoder detected.
So far, I have:
+ Tested multiple decoders by hooking them up to a locomotive (engine terminals only) and to the program track with the Error 2 on every one.
+ Tested a brand new out-of-the-package AD305 decoder with the same result.
+ Tested that same new decoder using address 3 on the main track with success.
+ Attempted to program new address into an old decoder on programming track but got Error 2.
Conclusion:
Something (speed of newer DCC system, etc.) is preventing the system from recognizing the old decoder.
I no longer have the old MRC 2000 DCC system to try. I still have an Atlas Commander that I occasionally use as a throttle on my system. I haven't tried using it to program the address.
Any help or suggestions would be appreciated.
Thanks!
