DC operation on Bachmann's EM-1

That's good news!

Bachmann wisely used a Soundtraxx decoder in the EM-1, a big improvement over some of the OEM models with Model Rectifier decoders.

Thanks Ed and Randy:  The fix was to delete all my custom settings back to factory settings, test both DC and DCC modes in those settings and than reprogram back to custom settings.  Apparently something corrupted the original program but this eliminated the problem.

 You need to check what value is in CV29. Here is a calculator to show what the values should be: http://www.2mm.org.uk/articles/cv29%20calculator.htm

 For DC to work, it should be set to 6 if using a short address or 38 for a long address. If it's 2 or 34, that's the problem, those values disable DC operation of the decoder.

Hi, Jim

I have two EM-1 but only run them on DCC and have never experienced any problems.

Have you browsed through the Bachmann EM-1 threads at their forum?

You may find additional information or post your question there. Type in HO em-1 in the search line. (or N if that's what you have)

Have you done any programming on the decoder? Sometimes there is a CV value that disables DC operation. Maybe a decoder reset is in order?

The EM-1 has a Soundtraxx "soundOn Board" decoder.

Hope this helps, Ed

My recently purchased Bachmann EM-1 was first operated in DC mode and ran fine.  When I programed it for DCC it also ran fine BUT later it would not go back to DC operation.  Is there a fix for this short of sending it back to Bachmann where it will languish for a month or more?
