The DT-AUX board adds a JST9, MC JST, FL2 JST, and a WOW101 Auxiallary connection to your decoder tester. Plug this board directly into the screw terminals of the Decoder Tester and you will have a complete, plug in decoder test setup.
Decoders which use the MTC 21-Pin connector use external transistors to turn on functions 5 and 6. All current WOW121 decoders support this interface.
This is an outdated standard that is no longer employed on WOW121 decoders. Only use this connector for WOW121-Steam decoders purchased before May 15, 2017.
Pair with a decoder tester aux board (DT-AUX) for added convenience when connecting decoders.
