TCS CVs This page will be my cheat sheet to have all the CVs in one place. When I get the "official" TCS documents, they are either not comprehensive, or have weird language like:"Not all CV's listed on this page are supported by TCS, and not all supported CV's are universally supported by all products. For example, RailCom configurations, lighting output assignment, and other features which require hardware support may not be applicable to your decoder. Pay special attention to the CV Addendums for your specific decoder. If you are unsure what your decoder is, you can read CV 249 the Decoder Hardware Model Identifier. If you are unsure if your decoder supports a feature, visit the specific product page for your decoder on TCS' Website for a full list of features." What the hey? That paragraph looks fine to a newbie, until you look for the documentation, and you find only ONE "comprehensive programming guide" for all decoders. I'm not doing this because I want to, I'm doing it to be able to use them dangit!
