LokPilot V4.0 DCC – Drive better with the 4th


„Better is the enemy of good“ it is said in colloquial language for generations. We fully agree with this proverb and are proud to present to you the brand-new LokPilot V4.0 DCC Decoder. This decoder supersedes from now on the „well and good“ LokPilot V3.0 DCC Decoder, which has achieved an excellent reputation among model railroaders all around the world. The new LokPilot V4.0 DCC is much „better“ in many respects based on the LokPilot family’s high standard performance. The LokPilot V4.0 Decoder will be offered in several varieties like its forerunner. The DCC version which we describe here is meant for all users who look for a temporary digital decoder and intend to use DCC and RailCom®. A further range of interface options enables you to find the appropriate decoder for your loco any time.

Operational modes

The LokPilot V4.0 DCC supports, like its forerunners the world-wide standarised DCC protocol and can be used in combination with all DCC systems on the market. It can also be used for DC operation and recognises operational modes automatically „on-the-fly". As a matter of course there are up to 9999 addresses in DCC operation. The LokPilot V4.0 DCC supports all common braking sections such as Zimo® HLU. A new feature is the ABC braking mode. Newly introduced by Lenz®, it simplifies stoppage in front of the signal thanks to its asymmetrical DCC signal. The LokPilot V4.0 DCC also fully supports the RailCom® standard and can be programmed with all current digital command stations.

Also new is the additional connection facility for an external „Power Pack". This optionally (coming in 2011) available energy store is able to energize the motor up to 2 seconds if the power supply is interrupted and makes you finally forget dirty tracks!

Motor management

From a LokPilot decoder, you rightly expect an excellent motor management. With the LokPilot V4.0 DCC, ESU introduces the once more improved fifth generation of load control. The standard frequency is adjusted adaptively to the speed with a basic frequency of 40 kHz. The result is an even better slow driving performance, ideal for older 3-pole or coreless motors. It’s also child’s play to adjust the regulation to the respective model. With this ESU sets a new standard. Nowhere else will you find better motor control. Promised!


Despite all its new functions, the new LokPilot V4.0 DCC is 9% smaller than its forerunner and thus easier to install. Beside the known LokPilot versions, with 8-pin or 6-pin NEM interface, and a new version with a 21MTC connector.

Analog operation

With LokPilot V4.0 DCC it’s not only possible to limit the start and top speed of your loco in analog mode, you can even determine which of the functions should be active.


The LokPilot V4.0 DCC decoder has 4 function outputs which achieve 250 mA load each(the all-new PluX22 Version has even nine function outputs!). They are separately dimmable and can be allocated individually to different light functions such as flashing light, firebox flicker, strobe – and double strobe, Ditch Light etc. Beyond that, the 21MTC connector version has two logical outputs which can be made alive via the adapter board 51968. Of course, the decoder is able to control the automatic decoupling move and push time for Roco®, Krois® and Telex® couplers and also offers a high beam function as a new feature. The „LED mode“ ensures that the light effects are set correctly when using LEDs.


The LokPilot V4.0 DCC supports all DCC programming modes including POM (Programming on the Main). Programming configuration variables (CV’s) is especially simple for owners of our ECoS control station: all options are displayed in plain language on the large screen and can easily be edited – even during operation on the layout.

Peace of mind

The LokPilot V4.0 DCC is overload and short-circuit protected, updatable and can be programmed comfortably from you command station or from your PC with the help of the ESU LokProgrammer. You are able to download brand-new software versions from our website as they become available. The software helps you to configure the decoder. That´s how comfort should be. With the LokPilot V4.0 DCC decoder you do not only purchase a very good decoder but also benefit from ESU’s years of experience in producing innovative digital decoders.

The LokPilot V4.0, top of the range, speaks DCC, Motorola® and Selectrix®. Armed for the coming NMRA DCC BiDirectional Standard („RailCom®"), it is for all ambitious model railroaders with technical vision and an appetite for new technologies.



The LokPilot V4.0 DCC speaks DCC only and is also armed for the coming NMRA DCC BiDirectional Standard („RailCom®") and it is predestined for all ambitious model railroaders with technical vision and an appetite for new technologies.

The LokPilot V4.0 M4 could be the choice of all Märklin®-systems fans, who want maximum play value.


The LokPilot Standard is a DCC decoder for modellers that are looking for a robust, high quality DCC decoder for their standard requirements, which should also be easily affordable.

  • These sets contain a LokPilot V4.0 decoder and an appropriate permanent magnet and 2 choke


Many model railroaders would like to exchange their old interface for the modern 21MTC version when converting their aged Märklin® locomotives and look for a simple and affordable

pportunity to do so.



    The LokPilot Fx V4.0 is used to digitize motor-less rolling stock. It offers up to 6 function outputs and speaks DCC, Motorola® and Selectrix®.

    Gauge N, TT:


    • The smallest member of the LokPilot V4.0 family has now a size of only 10.5mm x 8.1mm x


    The LokPilot micro V4.0 DCC is a genuine power house. It drives the loco motor with a continuous load capability of 0.75A and has significantly shrunk compared to its forerunner.


    The LokPilot Fx V3.0 is a functional decoder for motorless rolling stock. It speaks DCC and Cotorola® and can switch up tp six functions.Gauge G, 1:


    The all-new LokPilot XL V4.0 can be used with DCC, Motorola®, Selectrix® and M4 and cannot only provide up to 4.0A continuous load for the motor, but also switch up to 8 (!) function outputs. Thanks to the „PowerPack" energy reservoir, the orror of dirty tracks outside is a thing of the past.
