NMRA CV 249 - Decoder Model ID Number
TCS decoders are each assigned a unique identification number which is associated with the hardware/name of the decoder. This ID number is know as the Decoder Model, and is stored in CV249. The most common use for CV249 is by JMRI Decoder Pro, which uses this ID number to help identify and select the correct decoder definition is right for your decoder.
If you unsure what kind of decoder you have simply read the value in CV249 match it to its type in this table.
