This is the definitive reference work for 21 pin decoders, boards and adapters. If you thought that all 21 pin decoders would fit all 21 pin boards, you need to look at this. It goes into depth concerning all of the current 21 pin decoders and board types on the market today.
Those of you who use or are thinking of using 21 pin decoders (Scale Trainers and Bowers may have no choice) should dig into this article. Incompatibilities are generally near the end of the article so you may be able to start there but the entire article is enlightening.
The bottom line is:
You need to be sure the 21 pin decoder brand/model you intend to use matches the motherboard.
JMRI's Decoder Pro also supports these non sound 21 pin decoders:
- Digitrax DH126MT (two function)
- Digitrax DH166MT (CV select logic/full)
- Lenz Silver 21 Pin (probably logic level)
- NCE D16MTC (CV select logic/full)
Note the CV in the NCE decoder to select logic/full is not in the decoder definition yet, it will be added in JMRI test version 4.15.5.
If you have an idea for a blog post here, let me know. If I can comment on it, I will or I'll see if someone else can and post it.
