Title: 4-6-0 DCC on Board can't change CV's
Post by: CNR6218 on December 27, 2015, 02:50:30 PM
Can you tell me what is the decoder in the N scale 10 wheeler? I'm trying to change the CV3 and CV4 for the momentum and is not receiving the signal! I am  using the "page" selection on a programming track with a Digitrax DCS 50 Zephyr. The decoder on CV8 is not responding.....any ideas
Thanks

A 1000 Ohm, ΒΌ Watt resistor across the programming track is required for CV read and programming  a non-sound Bachmann(Lenz based) decoder used with a Digitrax Zephyr(DCS50) or Zephyr Xtra(DCS51).

Use Direct Mode  instead of PAGE

Does the resister need to be installed in the wire between system and track or just between the rails. Thank you for any help.

Do not install the resistor,  lay it anywhere across the rails of the programming track. Remove it after finishing programming a non-sound Bachmann (Lenz based) decoder used with a Digitrax Zephyr(DCS50) or Zephyr Xtra(DCS51).

Dualgauge, FWIW, I run a Zephyr Plus (DCS51) system with a mix of different locos. I got tired of jury-rigging the resistor across the track, so I cut an inexpensive alligator-clip test-lead in half and soldered the resistor between the two halves. Now, when I need to program one of my Bachmann locos, I just clip each end to the track and the Digitrax recognizes the decoder without any problems. Hope this helps.

Thank you for all the good information will pickup a resister and give that a try.
