I've had some difficulty programming a pair of Bachmann DCC equipped locos and thought I post here and see if anyone might be able to help.
I have a Spectrum 2-10-2 and Bachmann EZ-DCC GP30 that neither one will accept a 4-digit/long-address. They both appear to work fine otherwise, but are stuck running as default loco "03" only.
I have other EZ-DCC locos (GP38-2; SD40-2; GP35; GP30) that have all easily taken the long-address with little trouble. According to my notes, I went in and changed CV29 to accomidate the 4-digit address on those examples and all went quick and easy.
These other two mentioned above won't allow me to re-program CV29. I get "d nr" on my Digitrax Zephyr, when I try to read or program CV29. Also can't even get the 2-digit address to switch from its "03" default.
Any ideas? Defective decoders?
Thanks,
Workaround required to program a non-sound Bachmann decoder using a Digitrax Zephyr.
Workaround --- Place a 1000 Ohm resistor across the programming track. Remove the resistor after you finish programming the Bachmann decoder.
