Engine Decoder Identification

The Zephyr can read the decoders' settings without knowing the brand/model of decoder.

Reading the CV isn't the problem. How do I know which CV's are for what and what they can be set to? Is there a standard for CV's. Maybe I should search around for that. When I read the directions of how to change the CV settings, the 1st thing the instructions do is say "get out the decoder manufacture specs". Thanks Mike

Well there's an easy way and that is to use DecoderPro (JMRI). The other way is to go to the NMRA site and check the CV list. This won't help with the manufacture specific ones however. The only way you can learn what these do is the manual that comes with the decoder or is available on the manufactures site.

Search the NMRA web site for Dcc Recommended Practices. This will give you a list of all CV's and what they are for. The problem here is that a lot of CV's are manufacturer specific. The value in CV8 is a manufacturer ID. The NMRA web site should have a list of manufactures and their ID numbers. The value in CV7 is the software version number of the manufactures decoder software. Note this is not the model number of the decoder but the software version. Hope this helps

Here are the basics: CV01 (AD02) = 2-digit address CV02 = Vstart (starting voltage) CV03 = Acceleration momentum CV04 = Deceleration momentum CV29 = chooses speed steps, direction, 2- or 4-digit address, analog operation on/off

Mike,

Jon is absolutely correct about DecoderPro, but what he failed to mention is that they also list a huge number of decoder identification CV values here:
