ESU 51966 Changeover of Skis for LokSound V4.0, LokPilot V4.0, 21MTC Adapter Boards

Many railcars are equipped with a ski at both ends. In order to function correctly in block sections, and braking timely in front of red signals, it is vital for the decoder to employ only one ski for (voltage) pick up, depending on direction of travel. This to achieve is precisely the responsibility of our ski change-over electronics: It is hooked up between pick up and LokPilot-or LokSound decoder: After reprogramming, all ESU decoders (not LokPilot Basic V1.0, LokPilotXL DCC) can send a control-pulse that talks to the change-over electronics and then selects the "correct" ski. This combination works perfectly and without interference in digital and analog mode.

Please note: The LokPilot Basic V1.0 decoders is unappropriate for this kind of electronic.
