DecoderDB list

Not everyone can get an NMRA ID. For decoders without their own NMRA ID, ID 13 in CV8 (self-construction, DIY) is entered. However, a unique ID is necessary to uniquely identify a decoder.

We have created this list so that decoders with NMRA ID 13 can also be uniquely identified. The CVs 107 and 108 already provided for the 'Extended manufacturer identification' are used.

If you would like to have your own ID, please contact info(at)decoderdb.de

More info

CVs 107 and 108 are treated as 16-bit big-endian values.
Calculation: CV107*256 + CV108

CVs 109-110 should be used for the extended firmware version if CV7 is not sufficient.
The hardware ID of the decoder should be stored in CV111.

The IDs start at 256 to avoid confusion with the IDs in CV8.

The type ‘int’ is defined as a 16bit-little-endian value. Therefore CV 108 is first in the group.

XML-Code CV107/108

<ct:cvGroup type="int" mode="ro">
  <ct:cv number="108" type="byte" mode="ro"/>
  <ct:cv number="107" type="byte" mode="ro"/>
</ct:cvGroup>

SUSI

CVs 907 and 908 are used for SUSI modules.
Calculation: CV907*256 + CV908

The following CVs are still used:
HardwareId: CV902
Firmware version: CV901.CV904

XML-Code CV907/908

<ct:cvGroup type="int" mode="ro">
  <ct:cv number="908" type="byte" mode="ro"/>
  <ct:cv number="907" type="byte" mode="ro"/>
</ct:cvGroup>
