Decoder

[eagle37]

I have a new Bachmann USRA Light 2-10-2 steam loco, DCC
and am having trouble programming an address for its
decoder.  I get the message d nd.  The program track setup
seems to be o.k., since I've had no trouble programming
another loco.  I'm using a Digitrax Zephr.  Going to Digitrax
online I read that some locos do not draw enough power and
require a resistor across the terminals in order to program.
Would this be an engine with that issue?  Or is it more likely
that the engine has a bad decoder?

Dear Eagle,
If you're using Digitrax you'll have to use their work-around, which is the resistor.
Have fun!

Mr. Bach-man,
What is the work-around to programming, your decoders if I am using the Digitrax Super Chief? I sent an email to the service department and have not heard back from them. I would appreciate any help you can offer.
Thanks,
MC

Joining a Yahoo Digitax group would be a good idea.

Please note, there are Yahoo Groups for different DCC systems with a lot of info in their Files and Photos sections.
There is one for Bachmann DCC but hardly any messages posted.

See if this helps on your Zepher and decoder.


1K ohm 1/4 watt resistor across the a and b programming terminals.

I notice Jim Banner has commented on this.
