If he is using the Lokprogrammer, he should probably be reading the decoder before he does anything else. Once he does that, he'll know what the address is. In any case he says he has one-half of the big blow set working properly, so if he got that running he should be able to do the same thing to the other units to get them running.
Also, he seems to know what the values of CVs 3 and 4 are, so he must know what the addresses are in order to be able to get that information.
I'm sort of assuming that the locos came with the decoders installed, but maybe he installed them himself. So when he says what the "manufacturer's default values" are, I don't know if that means the manufacturer of the locomotive which came with a decoder, or the manufacturer of after market decoders that he installed himself. It is possible that the default values could be different.
