Will RailCom work with all DCC systems and all existing product?
RailCom has evolved over the years and there is a lot of the negative marketing information others have put out refers to earlier designs. As we have evolved the approach it has improved greatly. RailCom is not fully compatible with all decoders and systems that actually implement the NMRA DCC specifications. RailCom now has two modes. A simple mode with 2 bit cutout for older systems and a full 4 bit cutout mode for systems built to generate the additional preambles as specified in RP-9.3.1.
