<{POST_SNAPBACK}>Hi Kauri
The MRC decoders do not support read back and are not truly NMRA complient
the Lenz system is and is the only Manufacturer to offer a 10 year warranty
I can understand your frustration , I have a MultiMAUS system (produced and designed by Lenz)
Which has difficulty in changing CV1 on half of my loco's ,The MultiMAUS has, in Cv mode(service mode of Lenz) as apposed to POM there is only a small output current to the programing track (I have borrowed a Lenz system to do the job instead)
The Black box programmer (thanks for the file by the way , I finally found out how to read the dorx document)
Puts a higher current to the programming track in the Lenz "Service mode' This is what you need for changing CV1 of the sound decoders which have a greater current draw than a standard decoder
There may be an issue with the Athearn loco/MRC decoder you have . Try hooking the outputs of the black box directly to the Loco's power pickups , or wheels if you cant get to them , that may give a better transfer of power
Hope this helps
Regards Zmil
***When you followed the advice and changed CV17 and 18 (Which despite athaerns advice you don't have to do with a lenz, as it will programme a lond address directlyanyway) .....did you also change CV29?
try this:
do a factory reset on the decoder
programme CV17 and 18 directly as advised - (that means of course working out the hex values for them and entering those)
go to CV29 and make it 36
does long address work now?
