The LokPilot V4.0 M4 is multi-protocol decoder meaning it speaks all common data formats such as DCC, Motorola® and Selectrix® as well as M4. In DCC mode 14-128 speed steps are possible, as well as 2- and 4-digit addresses. You can activate up to 28 functions. Thanks to RailComPlus®, the decoders will be automatically recognized by a suitable command station. It is able to control all DCC programming modes und thus can be driven and programmed by all DCC-compatible digital command stations. CV values can be read out on the main track with corresponding command stations, thanks to RailCom®. There are indexed CVs for command stations which are only able to program CVs from 1-255. Motorola® users benefit from up to 28 speed steps with 255 addresses. Three further Motorola® addresses allow the activation of 16 functions. The installed programming mode makes re-programming with the venerable Control Unit® 6021 also possible. The M4 protocol ensures an automatic recognition of the decoder by mfx®-compatible command stations (e.g. Märklin® Central Station or mobile station®). Reprogramming of M4 decoders is still possible with the mentioned command stations, like with original Märklin® decoders. The LokPilot V4.0 M4 decoder auto-detects the known Märklin® braking sectors as well as the ZIMO® HLU braking commands or the Lenz® ABC system. Braking with DCC brake generators or with DC (“Brake on DC”) is supported. Furthermore you will be able to stop your train by using the Selectrix® braking diode. The LokPilot 4.0 decoder can be used for both analogue DC or AC locomotives. The decoder automatically switches between the different operating modes “on-the-fly”. In most cases one does not have to adjust anything.
