ESU 51954 Adapter Board, 9 pin, 21MTC, for Athearn Locomotives

Perfect for Athearn (and others) this new 9 pin (female) 21MTC (Male) adapter board allows the popular 6 output ESU 21MTC LokSound and LokPilot decoders to be easily added to your favorite locomotive.

More Functions

More and more locomotives now have front and rear headlights and front and rear flashing ditch lights. In order to accommodate for this in DCC 6 function outputs need to be used. As 8 and 9 pin DCC plugs only allow for 3 and 4 outputs respectively, this new adapter board will allow easy conversion to our 6 function decoders. 4 Outputs though the 9 pin plug and 2 more on solder pads.

1.5 Volt Lighting

As Athearn normally uses 1.5 volt bulbs it is often easier to use the supplied resistance in the Motherboards for those lights. This new adapter board also includes 1.5 volt light resistance for the additional 2 outputs that do not already go through the 9 pin JST plug. ESU decoders also include the ability to dim the outputs to match perfectly the on-board resistance with the adapter resistance if needed. There are also solder bridges for bypassing this resistance if bulbs are not used.

In addition there are extra common pads and solder pads for speakers directly on the adapter board.
