Introduction – The LokPilot Family

General Properties of all Decoders
5.2. Members of the LokPilot Family
All LokPilot V4.0 decoders have been completely redeveloped on
the basis of their predecessors´ excellent properties and they are
“better” in many respects.
All decoders of the LokPilot V4.0 family expand the capabilities
of their forerunners by further functions. These developments
further improve the driving characteristics, the operational reli-
ability and the flexibility of the decoders. The LokPilot decoder is
the first choice for any sophisticated model train enthusiast that
places great value on excellent load control, outstanding driving
characteristics at low speed, and the utmost flexibility due to ad-
aptation to specific requirements. LokPilot decoders automatically
detect the operating mode and are suitable for all commonly used
motors.
LokPilot decoders of the fourth generation offer you flexibility and
reliability that you would expect from a state-of-the-art decoder.
Future standards do not represent a problem either: due to the
flash technology, you can update the decoder at any time.
In order to suit the different scales and the related current draw of
the model locomotives, all LokPilot V4.0 decoders come in various
options that we now would like to introduce to you.
5.2.1. LokPilot V4.0
The LokPilot V4.0 is a multi-protocol decoder. It supports the Mär-
klin® Motorola® format, the DCC-format and Selectrix®.
It can also work on analogue DC or AC layouts. Thus, it is ideally
suitable for mixed Motorola® / DCC environments.
Due to its manifold lighting functions and its adaptability to dif-
ferent applications, it is the perfect all-rounder for your H0 loco-
motives.
5.2.2. LokPilot V4.0 DCC
The LokPilot V4.0 DCC is a „thoroughbred” DCC decoder. Except
for the Motorola® and Selectrix® protocol, it supports all func-
tions of the LokPilot V4.0. In analogue mode, it can only operate
on DC powered layouts.
The LokPilot V4.0 DCC is best suited for the DCC purist who does
not require multi-protocol operation and does not want to pay
for it either.
5.2.3. LokPilot micro V4.0
The LokPilot micro V4.0 is a real multi talent. Besides DCC and Mo-
torola® and Selectrix® and a maximum current draw of 0.75A, it
is ideal for the small scales with little room for decoders.
5.2.4. LokPilot micro V4.0 DCC
The LokPilot micro V4.0 DCC “only” speaks DCC, however, it is
compatible with RailComPlus®. For the rest it equals the LokPilot
micro V4.0 decoder.
5.2.5. LokPilot XL V4.0
The LokPilot XL V4.0 is suitable for the larger gauges such as 0
gauge, G gauge and 1 gauge and has been optimised to operate
with models in these gauges. It supports four data protocols. Be-
sides DCC with RailComPluS®, Motorola® and Selectrix® it also
supports the M4 data format and can automatically report to the
matching Märklin® central units. Due to its 8 function outputs as
well as 4 outputs for RC servos and a powerful motor end stage it
leaves nothing to be desired. Dirty track and their related problems
are a thing of the past due to the integral PowerPack.
5.2.6. LokPilot V4.0 M4
The LokPilot V4.0 M4 is ideal for everyone who does not want to
do without the automatic mfx® registration on a Märklin® central
station. Like the LokPilot V4.0 this decoder supports besides M4
the formats DCC with RailComPlus, Motorola® and Selectrix®
and can be operated on analogue layouts. The LokPilot V4.0 M4
fits into all popular H0 locomotives and can be programmed with
DCC command stations and also with Märklin® central units.

9
The LokPilot V4.0 supports and automatically detects the DCC
protocol with 14, 28, or 128 speed steps. Of course, operation
with the long 4-digit addresses is possible as well.
Contrary to the original Märklin®-decoders, LokPilot V4.0 decod-
ers support up to 255 addresses and 28 speed steps in Motorola®
mode. With the appropriate command station such as the ESU
ECoS, you can expand the system limits of the Motorola® system
considerably.
Furthermore, all LokPilot V4.0 decoders support RailComPlus®. A
RailComPlus®-compatible command station immediately recog-
nises a LokPilot V4.0 decoder fully automatically. The decoder will
transfer all of its important data to the command station. Finally,
you will never have to look for a loco address once again or carry
out any function mapping!
LokPilot XL V4.0 and LokPilot V4.0 M4 also support operation with
M4 and register automatically with Märklin® mfx® central units.
5.2.2. Motor Control
The most important function of digital decoders is motor control.
All LokPilot V4.0 decoders are designed for universal use and
therefore can control all commonly available DC motors, regard-
less if they are by ROCO®, Fleischmann®, Brawa®, Mehano®,
Bemo®, LGB®, Hübner®, Märklin® or others. Coreless motors
(such as Faulhaber® or Maxon®) also work fine with LokPilot.
You may continue to use any universal motors provided you re-
place the stator coils with a permanent magnet. You will find more
info on this topic in chapter 6.7.4.2.
Fifth-generation load compensation works with 20 resp. 40 kHz
and assures extremely silent operation, particularly with coreless
motors. Due to 10-bit technology, your locomotives will crawl at a
snail’s pace if so desired. Load compensation is easily adjustable to
various motor and gear combinations (compare with chapter 11).
With Dynamic Drive Control (DCC), you can limit the influence of
load control. Thus, you can control your locomotive in small throttle
notches for instance in the yard or on turnouts while the locomo-
General Properties of all Decoders
Both LokPilot V4.0 M4 and LokPilot V4.0 offer comprehensive
lighting effects, control of digital couplers as well as flexible func-
tion mapping.
5.2.7. LokPilot Fx V4.0
With the LokPilot Fx V4.0 you are able to digitalise motorless
vehicles. Therefore it has 6 function outputs. Therefore it has six
function outputs and can be operated with the Motorola® and
the DCC format. It also proves it´s worth on analogue DC and
AC layouts.
This LokPilot can be also used in combination with other LokPilot
or LokSound decoders.
5.2. General Properties of all Decoders
5.2.1. Operating Modes
All LokPilot V4.0 decoders (with the exception of the pure DCC
decoders) are true multi-protocol decoders with automatic detec-
tion of the operating mode „on-the-fly.“ The decoder analyses the
track signal and filters out the part that is reserved for it. Changing
from digital to analogue and back represents no problem what-
soever. This is important in case your e.g. fiddle yard still works in
analogue mode. Furthermore, all LokPilot decoders support the
relevant brake modes such as ROCO®, Lenz® or Märklin® and
stop as intended.
Especially the ABC brake sections are suitable for a simple stop
in front of the signal. LokPilot decoders achieve the maximum
compatibility with the operating system in order to enable you to
simulate even some unusual operational requirements.

General Properties of all Decoders
tive responds like the prototype at high speed on the main line
(for instance when climbing a gradient). In other words, if you do
not change the throttle setting then the locomotive will slow down
up the hill, as does the prototype. There is more info on this in
chapter 11.4.
The minimum and maximum speed of the LokPilot V4.0 is adjust-
able by setting two points which can be optionally adjusted by a
speed table with 28 entries.
Due to unique load compensation by ESU, there are no visible jerks
between speed steps – even in 14-speed-step-mode.
5.2.3. Analogue Mode
Quite a few LokPilot decoders replace analogue directional relays.
Therefore, you can not only set the starting speed and the maxi-
mum speed as well as pre-select which functions should be active
in analogue mode: even load compensation works in analogue
mode! This makes the LokPilot V4.0 work perfectly with analogue
locos: finally you are able to stop your older, too fast locos.
5.2.4. Functions
Standard features for LokPilot V4.0 decoders include the following
features: acceleration and brake times can be separately adjusted
and switched. The brightness of all function outputs can be sepa-
rately set and allocated to the desired function buttons (function
mapping).
There is a wide range of options: dimmer, flickering firebox, gyro-
light and mars-light, flash and double flash, blinker and alternate
blinker as well as switch functions with timers (e.g.: for Telex) and
a special coupler function for remote controlled couplers by Kr-
ois® and ROCO® including the automatic pushing and pulling.
Furthermore LokPilot XL decoders can also control up to 4 RC
servos directly.
The unique and once more improved ESU function mapping ena-
bles you to allocate every function to the function buttons F0 to
F15; even multiple allocations are possible. You will find more info
on this in chapter 12.
5.2.5. Programming
Where intended, LokPilot decoders support all programming
modes including POM (Programming-On-the-Main). You can use
any NMRA-DCC compatible command station for this purpose.
Even with the Märklin® central units 6020®, 6021®, Mobile Sta-
tion® and Central Station® all settings are adjusted electronically.
Most LokPilot V4.0 decoders support a simple-to-use program-
ming procedure.
Owners of the ESU ECoS enjoy an even more comfortable method
of programming: you can read all possible settings in plain text on
the large display and easily adjust them – even during operation!
LokPilot V4.0 M4 and LokPilot XL V4.0 will be automatically de-
tected and read by all Märklin® mfx® central units and can be
graphically programmed with them.
5.2.6. Operational Reliability
LokPilot decoders store the current operating status. Thanks to this
data storage, the decoder will start again as quickly as possible
after a service interruption. The LokPilot XL´s built-in PowerPack,
which also can be optionally installed into some decoders, assures
continuous power even in case of poor electrical contact or criti-
cally laid tracks.
5.2.7. Protection
All function outputs as well as the motor output have protection
against overload and short circuit. We want you to enjoy your Lok-
Pilot decoders for a long time.
5.2.8. Future built-in
All LokPilot V4.0 decoders are suitable for firmware updates due
to the flash memory. You may add new software functions at a
later stage.

6. Installing the Decoder
6.1. Requirements for Installation
The locomotive must be in perfect operating condition prior to the
conversion: Only a locomotive with faultless mechanical properties
and smooth running characteristics in analogue mode is worth
converting to digital. Check and replace all wear and tear parts
such as motor brushes, wheel contacts, light bulbs etc., if neces-
sary.
Please take note of the remarks in chapter 3 in order to prevent
possible damage of the decoder during installation!
6.2. Installing the Decoder
The components on the decoder must under no circumstances
touch any metal parts of the locomotive since this could lead to
short circuits and damage or even destruction of the decoder.
Therefore, all LokPilot decoders (with the exception of the ones with
the 21MTC or PluX interface) come with a protective shrink sleeve.
Never wrap the decoder in insulating tape. If there is no ventilation
around the decoder, it may lead to a heat build-up and ultimately
to the destruction of the decoder. Rather apply the insulating tape
to the metal parts of the locomotive.
Mount the decoder at a suitable location. In most model locomotives,
there is a dedicated space for the decoder. To hold the decoder in
place use double sided adhesive tape or some (just a little) hot glue.
6.3. Locomotives with 8-pin NEM 652 interface
Some LokPilot V4.0 decoders are supplied with an 8-pin interface
as per NEM 652 (refer to Fig 1). Installation in locomotives with
this interface is particularly easy:
Remove the locomotive body. Please observe the instructions in•
the manual of your locomotive!
Remove the dummy plug from the socket and keep it in a suitable•
place for later use.

6.4. Locomotives with 6-pin NEM 651 interface
Some LokPilot V4.0 decoders have a 6-pin NEM 651 plug (as per
Figure 2). Installation in locomotives with this interface is particu-
larly easy:
Remove the locomotive body.•
Remove the dummy plug from the socket and keep it for later use.•
Insert the plug of the decoder in such a way that pin 1 of the plug•
(this is the side with the red / orange wires) sits next to the corner
ofthesocketthatisusuallymarkedwith*,+,•or1.Pleasemake
sure that the pins are straight when inserting the plug.
6.5. Locomotives with 21MTC interface
Some LokPilot decoders are available with a variant of the 21MTC
interface as per Fig. 3. Installation in locomotives with this inter-
face is particularly easy since the plug-socket connector facilitates
the mechanical fixing as well.
Remove the locomotive body. Please observe the instructions in•
the manual of your locomotive!
Remove the dummy plug from the socket and keep it in a suitable•
place for later use
Search for the missing pin in the plug on the circuit board of the•
locomotive. The missing pin serves as the marker. Memorise its
location.
You can insert the decoder in two ways: either the pins are put•
through the decoder; the socket of the decoder remains visible af-
ter installation (mounting on top) or the decoder is inserted in such
a way that the pins go straight into the socket. Once the decoder
sits in the socket, the socket is hidden from view. This method is
common for Brawa® locomotives.
Which of the two mounting positions is the correct one depends•
solely on the locomotive. The position of the marker-pin is the
crucial indicator.
Plug the decoder into the socket in such a way that the locomotive•
interface corresponds with the decoder.
Do not apply too much pressure when inserting the plug. The de-•
coder must go in without force.
Check if the decoder sits correctly.•

Installing the Decoder
6.5.1. Connecting C-Sine motors („SoftDrive-Sinus“)
The LokPilot decoder cannot drive the newer Märklin® models
with C-Sine motors (also called „SoftDrive-Sinus“) directly. To facil-
itate this, a circuit board supplied ex works with the locomotive is
required. This circuit board will be controlled by a LokPilot decoder.
Märklin® uses the 21MTC interface installed on this circuit board
and thus utilises the normal motor commands from the decoder or
a SUSU interface for the exchange of information.
The LokPilot V4.0 with the 21MTC interface is suitable for control-
ling the C-Sine control electronics provided some parameters are
set accordingly. Chapter 11.5. explains the necessary steps.

6.6. Loks mit PluX-Schnittstelle
Some LokPilot decoders are supplied with a PluX12 plug. These
decoders can also be installed in locomotives with a PluX22 inter-
face. One position on the multi-pin plug of the decoder has no pin
(index pin). This position should be marked in the locomotive.
Please consider the correct seating of the decoder on the PluX
socket!
6.8. Locomotives without interface
All LokPilot decoders have an interface (plug). There is no „wires-
only“ version. Please remove the plug at the end of the harness
should this become necessary.
Please do not extend any wires at the decoder end. If necessary
use an extension harness (also refer to chapter 17).
6.7. Locomotives with Next18 interface
Some LokPilot micro decoders are shipped with an 18-pin Next18
interface. More information about how to install the decoder is
given in chapter 6.5.

6.8.5. Colour Coding by Märklin®
Märklin® uses a different colour coding system compared to the
DCC colours. Please refer to figure 13 for more information.
6.8.6. Motor and track connections
Firstly, please cut all wires installed in the locomotive. Take special
care to remove any connections to the chassis (ground): the motor
leads must be positively potential-free, in other words they may
not have any contact to the chassis or body or the wheels and
wheel contacts.
It is particularly easy to overlook such connections in Fleischmann®
locomotives.
Make notes of which motor lead connects the motor with the
right and the left wheel contact.This avoids mistakes and assures
that your locomotive runs in the right direction.
Please check all connections with an Ohmmeter. Search for
short circuits, particularly between the motor leads and the
wheel contacts.
Connect the red wire to the right rail pickup or the centre pick•
up in AC models.
Connect the black wire to the left rail pickup or the chassis in•
AC models.
Connect the orange wire with the motor terminal, which originally•
lead to the right wheel pick up (centre pick up in AC models).
The grey wire goes to the terminal, which originally connected to•
the left rail (chassis for AC models).
6.8.6.1. Connecting DC and Coreless Motors
You may use all DC motors commonly used for model trains pro-
vided they do not exceed the current limit of the decoder.
In some cases with the 5-pole High Performance Drive by Märk-
lin®, you may find three anti-interference capacitors.
The two capacitors connected directly to the motor leads and the
motor housing MUST be removed (also refer to Fig. 14).

6.8.6.2. Connecting Universal Motors with HAMO-Conversions
Do not wire universal motors installed in many older Märklin®
locomotives (also known as AC motors) directly to LokPilot de-
coders. You must modify the motor by first installing permanent
magnets – so called HAMO magnets.
You may purchase these magnets from your ESU dealer.
We supply three types of magnets. Please refer to chapter 18.2.
for more information regarding motor conversions with perma-
nent magnets.
6.9. Connecting Additional Functions
You can wire any kind of load such as light bulbs, LEDs (light emit-
ting diodes), smoke generators or similar devices to the function
outputs provided the maximum current draw is less than that of
the decoder output.
The permitted maximum current draw per function output is listed
in chapter 20 under „Technical Data.“
Please make sure that the load does not exceed the permitted
maximum current and there are no short circuits. The outputs of
the LokPilot have protection but if an external voltage is applied,
the outputs may suffer damage or destruction.
6.9.1. Overload Protection of Function Outputs (Blinking)
The function outputs of LokPilot decoders have electronic pro-
tection against overload and short circuit. The decoder keeps
checking the sum of all function output currents. If the current
is too high, the decoder will switch off the outputs. After about
1 second, the decoder tries to switch them on again. Should the
current still be too high – perhaps due to a short circuit – the same
procedure starts again.
When using light bulbs (incandescent lamps) please note the fol-
lowing: they draw a very high „inrush current“ when they are
switched on, that becomes lower after a few moments. Therefore,
it can happen with 12V bulbs that the headlights „flash“ briefly
during switch-on and then extinguish due to the overload protec-
tion of the decoder. The lights will be shortly switch on and off
again in a one-second cycle. This results from a much too high
inrush current of the bulbs; the decoder is not able to distinguish
between the bulbs´ high inrush current and an overload. Therefore
it is important to install the correct bulbs.
6.9.1.1. Suitable light bulbs
Only install bulbs rated 16V or higher and with a nominal current
draw, that does not exceed 50 mA.
Many older models by ROCO® and Fleischmann® have 12V bulbs
installed. They draw a high current, become very hot, and may
cause damage to the locomotive. Replace them with 16V bulbs.
6.9.1.2. Micro incandescent lamps wired to LokPilot XL V4.0
The LokPilot XL V4.0 decoder is suitable for direct connection of
micro incandescent lamps. The decoder has an integral voltage
regulator for this purpose. The default setting is 1.8V designed for
long life of 3V lamps. Do not connect the return wire of the lamp
to U+ but rather to the terminal marked “UVAR”.
Installing the Decoder
Remove capacitors!

Installing the Decoder
You may change the voltage setting by exchanging a resistor. An
SMD resistor is required. Type 0805, power rating 0.125W:
R124

Rear light
Head light
UVAR (1,5-3V) Voltage R124
1.5V 33 kOhms
2.5V unsolder
3.0V 48 kOhms, unsolder R125
The maximum load of the UVAR output is 500mA.
6.9.2. Using LEDs
If you like to use LEDs, then a resistor must be wired in series with
the LEDs. It should have a rating between 470 Ohms and 2.2 kO-
hms. Running the LEDs without this resistor will lead to their im-
mediate destruction! Unlike lightbulbs, LEDs are polarity-sensitive.
The minus (cathode) end of the LED is connected to the function
output, the plus (anode) end is connected to the blue (function
common) wire.
Please to not forget to switch the respective function output to
LED mode. This will ensure a prototypical presentation of all light
effects. Please refer to chapter 12.3. for more details.
