6.9.4. Using AUX3 and AUX46.9.4.1. LokPilot with 21MTC InterfaceLokPilot decoders with 21MTC interface have two additional outputs besides the 4 standard outputs, namely AUX3 and AUX4. Since they are pure „logic-outputs“, it is not possible to connect any external loads directly. External power transistors are required. Connect AUX3 and AUX4 via the 21MTC interface; there are equal to the other outputs. ESU offers an appropriate adapater board (art.no. 51968) with transistors.
