7.0 Basic Decoder Setup CVs
The decoder’s address and the configuration register CVs are the basic CVs 
needed to operate a decoder.
7.1 Decoder Addresses
The decoder’s address is the unique identification number that lets that decoder 
recognize commands sent to it by the command station. Once you program the 
decoder’s address, it is remembered by the decoder until it is changed.
Decoders can be programmed with both 2 digit and 4 digit addresses but only 
one or the other will be in use at any time. Whether the 2 or 4 digit address is 
used is determined by CV29, the configuration register.
