On request, this dummy plug replaces a LokSound 5 L or LokSound L V4.0 decoder in locomotives that are to run on analog systems. The dummy plug is plugged onto the Adapt board 51959. DIP switches can be used to configure which function outputs should be switched on or off. The definition of the direction of travel is possible. The dummy plug is useful for converters who want to prepare their track 0 or track 1 locos digitally using the 51959 board, but do not want to install a LokSound 5 L decoder straight away.
