Having difficulty changing the decoder address of Bachmann GP40 diesel locomotive.  Am using Digitrax Zephyr DCC system and keep getting error message "d nA" when trying to change address or CV values of new locomotive.  Any suggestions for a successful solution?

The usual solution is to put a 1000 ohm resistor across the programming track.  This will allow your Zephyr to read the acknowledgement signal returned by the decoder.  The alternative is to use blast mode programming in which your Zephyr does not need an acknowledgement signal in order to proceed.  Most people prefer the 1k resistor method.
Growing older is mandatory but growing up is optional.

Thanks for the input Jim and Rich.  Will give it a try.
