Put more fun in your DCC operations with these tiny, function-only decoders. Use them to control lighting effects aboard your locomotives and other rolling stock. Approximate size is 0.461 x 0.31 x 0.161". Function decoders support two- and four-digit addressing and feature on/off functions or configurable strobe operation to simulate special lighting effects. TL1 supports F0 forward and reverse, its great for adding a FRED at the end of the train. TF2 supports F0-F10 and TF4 supports F0-F12, expanding the functions available for making loco lighting more realistic. Programmable from DCC compatible programmers which can handle Digitrax transponding.
