Digitrax Decoder Series Numbers
Over the years as technology advanced, Digitrax has added more and more features to our mobile decoders. Also, over time, the industry standards and uses of come CVs have changed. Each of our decoder web pages includes a link to a specification sheet for that particular decoder so that you will know which CVs are used for which features in that particular model.
Digitrax uses series numbers to let customers know which feature set is part of a particular decoder.
The fifth character of each mobile + function decoder part number is the Digitrax series designator. For sound + motor + function decoders we typically use the sixth character as the series designator. There are variations in a few part numbers.
