Important notes
3. Important notes – Please read this chapter first
We congratulate you on your purchase of an ESU Switch Pilot
decoder. This manual will guide you step by step through the
features of SwitchPilot respectively SwichPilot Extension.
Important warning:
Please read this manual carefully. Although the SwitchPilot has
been designed as a robust device an incorrect connection may
lead to faults or even to the destruction of the device. Avoid any
“costly” experiments.
•The Switch Pilot is exclusively intended for use with model train
layouts only. It may only be operated with the components listed
here. Any other use is not permitted.
•Any wiring has to be carried out while power is disconnected.
•Any power supply must be protected by a fuse or circuit breaker
to avoid any potential hazards such as burning cables in case of
a short circuit. Only use transformers specifically designed for
model trains that bear the VDE/EN marks.
•Never operate the SwitchPilot unattended. The SwitchPilot is
not a (children’s) toy.
•Adhere to the wiring principles as outlined in this manual for
wiring any external components. Other circuitry may cause
damage to the SwitchPilot.
•SwitchPilot is not water proof. It is not intended for outside
use. If you use this product for exterior applications you do so
at your own risk.
•Do not attempt to open your SwitchPilot module. Improper
treatment may cause damage or destruction.
4. How this manual will help you
This manual was divided into a few chapters, which will gradually
show you how to operate the products 51800,51801 and 51802.
Chapter 5 includes an overview of the features of the single
SwitchPilot decoders.
In chapter 7 we deal with the connection of your layout.
If you wish to adjust the factory settings of your decoder
individually, just do so. In chapter 7 - 11, you will find detailed
explanations about which settings are possible and how you can
change them.
Statements about technical data can be found in chapter 16 as
well as a list of all CVs assisted, if necessary.
Unless indicated otherwise, all statements exclusively refer to
members of the SwitchPilot family. In case a decoder should not
work with a special function, this will be mentioned explicitly.

5.1. Members of the SwitchPilot family
The ESU SwitchPilot decoders are especially optimized for
stationary operation on your layout. Not matter if you wish to
activate turnouts, signals, magnetic un-couplers, light bulbs and
other stationary loads or even if you prefer a „state of the art
servo motor: One of the SwitchPilot decoders will be quite useful
for you, for sure.
The SwitchPilot decoders can be supplied with power either from
the digital system or from an external AC- or DC-power source.
Due to an installed full bridge rectification and backup memory
you can do without any additional „power modules“.
All SwitchPilots are multi protocol capable and therefore can
either be operated with command stations as per the Märklin®-
Motorola® system (e.g.: 6021, Central Station®) or with DCC
compliant command stations.
SwitchPilot Decoders are able to control all current DCC
programming modes and can be set up either on the main track
or the programming track. Thanks to RailCom® it is also possible
to read out data on the main track. Some of the SwitchPilot
decoders can be easily set up via a three-button, LED input unit.
SwitchPilot decoders are shipped in a robust body and stand out
due to their excellent price-performance ratio.

5.1.2. SwitchPilot
The SwitchPilot is a universal decoder for users who mainly have
double-solenoid motors installed, but would like to test the servo
technology.
Hence the SwitchPilot has four outputs (1-4) for switching of up
to 4 double-solenoid accessories (e.g. switches) or 8 accessories
like uncouplers or light functions.
Each output can be programed individually for continuous or
pulsed output with variable pulse duration or blinking.
Thus it is possible to connect light bulbs or LEDs without any
additional relays. Automatic fading assures prototypical run-up
and shut-down of signal lamps.
In addition two commercially available RC-servos for hobby
applications may be wired directly to the SwitchPilot. Their speed
and end position can be adapted as required.
Due to the integral DCC RailCom® - transmitter it is possible to
provide status feed back of the accessory to the command station.
For instance an ESU ECoS command station can then display the
manually activated change of status.
Of course the transistor outputs of SwitchPilot are electronically
protected against overload and short circuit.

5.1.3. SwitchPilot Servo
The SwitchPilot Servo is a masterpiece among accessory decoders:
it was specifically developed for controlling up to four remote-
controlled servo motors. The SwitchPilot Servo activates these
actuators very precisely and thus is able to control not only
switches, but also other slow motion sequences.
The SwitchPilot Servo has a built-in „Power-on-Pulse-Suppressi-
on“ feature to eliminate or reduce the „twitching“ of the RC
servo when current is being applied. The SwitchPilot Servo can
also be used without a digital control unit. For this, eight push
buttons can be connected to directly control the servo motor.
Thanks to the input unit of three buttons on the decoder, the
servo state as well as speed can be set up pretty easily.
You are using servos and are asking yourself which SwitchPilot
should you use? If you are only controlling turnouts and light
signals the SwitchPilot is the right decoder for you. If you would
like to control railroad crossings or any other devices that might
require slow motion, you should definitely use the SwitchPilot
Servo.
5.1.4. SwitchPilot Extension
For operating motor drives for turnouts or for the polarization of
the frogs you require a relay with potential free contacts. For this
purpose each SwitchPilot can be connected to a SwitchPilot Ex-
tension which can be plugged into the side of the SwitchPilot
and receive its power from it.
Each SwitchPilot Extension module has 4 by 2 relay outputs that
are operated in parallel to the corresponding outputs of the
SwitchPilot. This corresponds to the established k84-solution.
SwitchPilot Servo
5.2. Features
5.2.1. Operational modes
All SwitchPilots are multi protocol capable and therefore can
either be operated with command stations as per the Märklin®-
Motorola® system (e.g.: 6021, Central Station®) or with DCC
compliant command stations. For this SwitchPilot decoders must
be contacted with solenoid accessory addresses. Therefore,
operation with the Lokmaus 2 is not possible. The Lokmaus 2
does not send DCC commands to solenoid devices.
SwitchPilot
The SwitchPilot has a switch to select different operating modes.
Thus you can easily set the desired mode. Therefore
“programming” is not necessary for most standard applications.
This switch only operates the four transistor output pairs 1 to 4.
The servo outputs are not affected.
The operating mode switch is only for the use with Motorola
control units to enable compatibility with Marklin controllers. If
the SwitchPilot is used with the DCC protocol the operating mode
switch needs to stay at the middle position (factory default).
5.2.1.1. k83 mode
SwitchPilot
When you push the slide into the k83 position then the outputs
1 to 4 will be switched to pulse operation regardless of the
programed settings. The SwitchPilot behaves exactly like a
Märklin® k83. Use this mode whenever you want to operate
conventional solenoid drives.

7
5.2.1.2. k84 mode
SwitchPilot
In the k84-mode the outputs 1 to 4 will be set to variable
regardless of any pre-programed settings. The SwitchPilot behaves
exactly like a Märklin® k84.
Use this mode to operate LEDs or light bulbs and whenever you
do not require any specific programming.
All consumer loads are directly electrified by the SwitchPilot. You
must not connect any external voltage!
5.2.1.3. User mode
SwitchPilot
The user mode is switched on by setting the switch for selecting
the operating mode into the centre position. Only in this mode
the outputs 1 to 4 will behave according to the software controlled
settings.
This is the correct use to DCC format, k83 and k84-Modus are
only meant for Motorola® command stations.
5.2.2. Transistor outputs
SwitchPilot
The SwitchPilot has a total of 8 transistor outputs that are grouped
in four pairs 1 to 4. Each pair has two outputs, OutA and OutB.
there are also two separate servo outputs.
The transistor outputs can be set to continuous, to pulsed power
or to alternating blinking.
Pulsed output:
If the output is set to pulse operation it will be activated as soon
as a command is received. At the same time a timer starts
counting: the “on-time” (duration of pulse) is determined by a
pre-programed value. The output cannot be active for longer or
shorter than this value. Should you let go of the button before
the end of the first pulse then the output remains active until the
pre-determined time has been reached. If you press the button
longer than the pre-determined pulse duration then the output
is switched off even though the button is still pressed.
The limitation of the pulse duration helps avoid damage to
solenoids.
The pulse duration can be set in such a way that the outputs are
active as long as the button on the control panel is pressed. This
operating mode is compatible with Märklin® k83 decoders.
Variable:
Pressing the appropriate button on the control panel (e.g.: “red”
for Märklin® central units or „+“ for Lenz Digital Plus®) switches
on the first output Out A. It remains on until the corresponding
button for output Out B is activated. Out A and Out B work like
a change over switch.
Logically this operating mode complies with the Märklin® k84
decoder. From every output EITHER Out A OR Out B is active.
Both cannot be switched at the same time!
Alternating blinker:
In this mode the terminals Out A und Out B of an output will be
activated alternately. This is quite useful for the blinking red lights
at level crossings amongst others.
The “on-time” can be set in the same fashion as the pulse
duration.
Subject to the pulse duration and also in continuous mode it
may happen that several outputs are on at the same time. Please
note that the total current of all connected loads must not exceed
the total permitted load of the decoder, namely 3.0 A.
5.2.3. Servo outputs
SwitchPilot SwitchPilot Servo
RC-servos can be connected to both SwitchPilot decoders.
Compared to gear motors, servos are intelligent actuators with
integrated intelligence which can move to the self-desired position
and can also hold this state. In doing so, they force a different
angle and speed. Will leverage against a force out, it controls
the servo with all force against the angle constantly striving itj

8
should have to keep.
The nominal position will be set by a pulse line (orange on
Graupner ® servos, otherwise white). A constant voltage (4.8 V
- 6V) completes the interface.
On the pulse line the servo expects in a time interval of 20 –
25ms a positive impulse with a length between 1.0ms and 2.0ms.
The length of the pulse is directly proportional to the desired
target position.
If the servo does not receive a signal, the motor gets no power,
so it follows the mechanical forces on the lever.
Servos are available in various designs and sizes. They differ also
in the gear box and actuator angle. There are, for example, servos
to make wind sail adjustment, which makes several revolutions.
ESU offers with the servo motor (51803) a very small servo drive.
This includes all the necessary parts for the switches or turnouts
and you don’t need to search for all these small parts.
Never try to turn the actuator of a servo by hand. The gears
of the servo can be destroyed.
5.2.4. Relay outputs
SwitchPilot Extension
Outputs 1 through 4 each offer a relay output A and B which are
switched together (DPDT, bi-stable). Each relay output
corresponds with the transistor output of the SwitchPilot or the
servo output of the SwitchPilot Servo: If output A is active (or
servo setting A is reached) the terminals I and Com of the relay
output are connected. Is output B on the SwitchPilot active (or
servo setting B is reached) the terminals II and Com are connected.
5.2.5. Feedback inputs
SwitchPilot
Through RailCom® the SwitchPilot can send the current turnout
position back to the digital control unit. For this the turnout needs
to have the corresponding feedback contacts which must be
connected to feedback contact input FB A and/or FB A. (see Figure
7.7 for details)
5.2.6. Push Button Inputs
SwitchPilot Servo
The SwitchPilot Servo can also be used without a digital system.
The setting of servos 1 through 4 can be set with external push
buttons. These could be toggle switches or push buttons known
from the famous analog switch boards. (See Figure 13 for more
details)
6. Connection to the digital system
We recommend setting all parameters of the SwitchPilot prior
to installing the unit on your layout.

simultaneously the power supply of the digital system may be
used.
The screw terminals Pw A and Pw B are wired in parallel to the
terminal Trk A and Trk B.
Depending on the used solenoid devices the digital control unit
might not be able to supply enough current for a safe operation.

Depending on the used solenoid devices the digital control unit
might not be able to supply enough current for a safe operation.
In this case an external transformer which can supply enough
current for these solenoid devices needs to be connected to the
SwitchPilot (see 6.5). When using certain solenoid devices (i.e.
Märklin® K track turnouts or PECO® motors) you should consider
an external supply of powerSwitchPilot (see 6.5).
6.5 Separate power supply
For larger layouts with many devices controlled by SwitchPilots
and simultaneously active we recommend to utilise a separate
power supply; in this manner the power for switching the devices
is not drawn from the track and thus reduces the load on the
digital system.
Only use commercially available equipment designed for model
trains and also take note of the maximum voltage as stated in
chapter 16 in order to avoid any potential damage.
This way of connecting cannot be used for programming on
the programming track, compare chapter 7.2.2.1
6.6. Wiring the SwitchPilot Extension
The SwitchPilot Extension module is connected by inserting it
into the multi-pin connectors on the side of the SwitchPilot; push
until the retaining clips make positive contact.
Please also refer to figure 1.
The internal logic and relays of the SwitchPilot Extension module
receive power from the SwitchPilot.

6.7. Wiring of transistor outputs
SwitchPilot
6.7.1. Connecting double-coil solenoids
You may use all commercially available double-coil solenoid drives
by all major manufacturers with SwitchPilot. Figure 4 shows how
to wire output 1:
a) The common wire of the solenoid is wired to screw
terminal C.
b) The wire leading to the first coil is connected to terminal Out
A.
c) The wire leading to the second coil is connected to terminal
Out B.
Should the aspect shown on your control panel not be as desired
(in other words: if straight and diverging route are exchanged)
simply swap the wires between terminals Out A and Out B.
SwitchPilot can also handle PECO® turnouts. However, their
current consumption is so high that you must adjust the overload
setting of the SwitchPilot. Please refer to chapter 9.3. for details.
As shown in Figure 5 the double-coil turnouts can be switched
with two optional push buttons without a digital command. The
needed ground solder pad is not available on all SwitchPilot
surfaces.

6.7.2. Wiring daylight signals and light bulbs or LEDs
If you use daylight signals with incandescent lamps (light bulbs)
or LEDs you must set the corresponding output to continuous
mode.
If the signal has incandescent lamps as shown for output 2 in
figure 5 you may wire the lamps directly to the terminals of the
SwitchPilot.
In order to limit the current for signals with LEDs a resistor must
be wired in series with the LEDs. This is shown for output 4 in
figure 5.
Please check if your signal already has a built-in resistor. Applying
power without this resistor will destroy the LEDs immediately!
If there is no resistor in place you must wire this resistor marked
“R” in series to the LEDs. Subject to the supply voltage and the
desired brightness of the signal the resistor should have a rating
of about 1 kohm to 2.2 kohm.
The screw terminal C of each output has positive potential.
Therefore the cathode of the LEDs must be connected to the
terminals Out A respectively Out B.
6.7.3. Wiring a motor drive
SwitchPilot Extension
The SwitchPilot can operate motor drives for turnouts with the
help of the SwitchPilot Extension. The direction of the motor is
reversed by changing the polarity of the voltage on the motor
terminals thus changing the position of the turnout or the aspect
of a semaphore signal.
Only use motor drives with limit stop contacts to avoid overheating
or a burnout of the motor. The relay outputs of the SwitchPilot
Extension always connect the supply voltage to the load.
A motor drive is wired as shown in figure 6. It will be energized
by the SwitchPilot.
Please take note of the permitted maximum supply voltage of
your motor drive as stated in its manual.

6.8. Wiring a servo
SwitchPilot SwitchPilot Servo
All commercially available RC-servos for hobby applications may
be used. They must have a three-pole terminal and operate on a
positive pulse. The SwitchPilot (Servo) provides 5V to the servo.
Figure 7 on page 13 shows the usual connection.
Simply insert the wire from the servo into the appropriate socket
of the SwitchPilot (Servo). Generally the white or orange wire is
used for the pulsed outputs of the servo.
Please refer to the wiring diagrams on the housing of the
SwitchPilot. Incorrect connections may destroy either the servo
or the SwitchPilot!
The servo outputs can be configured individually as you can see
in chapter 10.
6.9. Wiring feedback contacts
SwitchPilot
The SwitchPilot can report the actual aspect or position of the
turnout to the command station via RailCom®. The turnout must
have some extra contacts for this. Figure 6 on page 9 illustrates
this situation:
a) Connecting a motor of a turnout with limit stop contacts.
Connect the terminals Out A with FB A and Out B with FB B.
b) Connecting a motor with separate feedback contacts: connect
the feedback contacts with terminal FB A respectively FB B
and the common wire of the feedback contacts to terminal C.
How the status (feedback) is displayed depends on your command
station. The ESU ECoS®-command station can display the status
on the turnout control panel with software 1.1.0 and higher.
Further information about feedback of switches via RailCom®
can be found in chapter 11.

6.10. Polarizing electric frogs
SwitchPilot Extension
You may polarize (supply power of the correct polarity) to the
electro-frog of your turnout (compare figure 9).
If you would like to use a servo with your turnout it is most often
necessary to choose the exact timing in such a way that the relays
only switches when the servo is positioned in the middle between
setting A and B. This way shorts are being prevented. See Chapter
13 for more details.
7. Decoder settings (programming)
Chapter 7 is about changing the settings of the SwitchPilot
decoder. In case you are not familiar with the CVs please take
some time to read through the sometimes very complex
explanations.
After an introduction into the world of parameters in Chapter
7.1, Chapter 7.2 explains how to change the parameters with
different DCC control units.
Chapters 8 through 11 explain which parameters influence the
behavior of the SwitchPilot decoder.
7.1. Changeable decoder settings
Certain capabilities of the SwitchPilot decoder like the amount
of function outputs or the maximum current load are physically
limited through hardware and are not changeable. However, there
are still plenty of possibilities to change the behavior of the
SwitchPilot decoder through software changes.
For each individual parameter there are one or more storage
locations within the decoder in which numbers or letters can be
stored. You can think of these storage locations as index cards
which are kept in a large file cabinet. In order to find the indivi-
dual index cards each one has a number or description with the
property of the card, e.g. „Loco Address“ or „Maximum Speed“.
Now imagine that those cards can be written on with a pencil;
changes are always possible through erasing and writing. Not all
„cards“ can be written on. Certain pieces of information like the
manufacturer identification for ESU are hardcoded.
The content of these storage locations can be chosen by you and
is being read and considered by the decoder. You can fill the
storage locations with any value through a procedure that is also
known as programming.
7.1.1. Configuration Variables (CV)
All SwitchPilot decoders follow the CV concept which was
developed in the United States. The name CV (Configuration
Variable) is derived from the fact that the memory cells being
described above are not only variable but can also configure the
behavior of the decoder.
7.1.1.1. Standardization
The NMRA (National Model Railroad Association) has specified
which CV controls what function in a decoder. The DCC norm
describes the CVs with numbers whereby the most important
ones are given. Thereby the handling of CVs is simplified for the
user since decoders of many manufacturers follow this
standardization and the learned handling of CVs can be applied
everywhere. Within the DCC CV concept number values between
0 and 255 can be written into CVs. Each CV consists of exactly
one number. While the position (CV number) has been
predetermined the actual range of values can vary. Not all CVs
need to accept values between 0 and 255. Allowed values for
the SwitchPilot decoder are shown in the list in Chapter 16.
Decoder settings (programming)

16
7.1.1.2. Bits and Bytes
Most CVs contain numerical values: CV 8 for example contains
the manufacturer’s identification. This one can range from 1 to
255. Other CVs can be understood as a collection point of diffe-
rent switches which together control different functions (most
often turning on or off). Good examples are CVs 28 and 29: The
intended value for this CV needs to be calculated. This value
depends on the desired parameter. Take a look at the table in
Chapter 17 and its description for CV34: First decide which option
needs to be turned on or off. In the value column are two numbers
for each option. If the option is turned off the value is set 0,
otherwise a number between 1 and 8. Add those two numerical
values for this specific option and you will get the value which
needs to be written into the CV.
Example:
Assuming you would like to activate the SwitchPilot’s „zoom“
function on outputs 1 and 3, the value of CV 34 needs to be set
5 ( 1 + 0 + 4 + 0 = 5 ).
7.2. Programming with DCC systems
SwitchPilot decoders understand all programming methods of
the NMRA, so in addition to the programming track modes (Direct
Mode, Register Mode, Page Mode) also the main track
programming „POM“ (programming on the main).
With POM you can comfortably program your decoder without
having take your locomotive off the track. For this the central
unit must contact the decoder with its specific address, for
example: „Decoder 10, write value 1 into CV 3“. The decoder
address must be known. The reading of CV values is not possible
in this case.
It is possible to read out CVs on the main track with RailCom®.
More information can be found in chapter 11.
Programming
CV values can be read and set on the programming track – a
suitable DCC system provided. Furthermore you can program
decoders on the programming track without knowing the decoder
address since the central unit uses commands like „Write value
1 to CV3!“ Each decoder that receives this command will also
execute it.
ESU counts the bits from 0 to 7 as specified in the DCC norm
while some manufacturers (e.g. Lenz) count the bits from 1 to 8.
Please keep this in mind when programming our decoders with
such systems.
7.2.1. Programming on the main track
The SwitchPilot can remain installed on your layout during the
programming. In order for the main track programming to work
your digital system must also understand „Programming on the
Main: (POM) for solenoid devices. In addition you must know
the decoder address of your SwitchPilot decoder.
Please make sure to carefully read Chapter 8 so you understand
the difference between turnout number and decoder address.
Thanks to the built-in RailCom® technology, ECoS owners with
firmware 1.1.0 or later can program the SwitchPilot while it is
installed on the layout. More can be find in chapter 11.
7.2.2. Programming on the programming track
For programming specific parameters of the decoder outputs the
SwitchPilot has to be programed on the programming track. This
is most practical prior to installation on the layout.

17
7.2.2.1. Connecting to the programming track
SwitchPilot
For programming please connect the SwitchPilot as shown in
figure 10 to your digital system. In this instance the power must
be supplied from the command station.
The SwitchPilot “understands” all relevant DCC programming
modes. It is best to program it in DCC Direct Mode.
In order to be able to read out any data you must connect a load
to output 1 Out A that draws more than 60 mA, for instance a
light bulb or a 180 Ohm / 1 Watt resistor.
SwitchPilot Servo
For programming please connect the SwitchPilot as shown in
figure 11 to your digital system. In this instance the power must
be supplied from the command station.
The SwitchPilot Servo “understands” all relevant DCC
programming modes. It is best to program it in DCC Direct Mode.
A load resistance with 180 ohm is already built in.
The reading of CVs should function with all DCC conformal
central units and was tested with ESU ECoS, Bachmann® Dyna-
mis ProBox®, Uhlenbrock® Intellibox® and Lenz® Digital Plus
V3®. Unfortunately, Digitrax® units do not supply enough current
on the programming output, ZIMO® units sometimes report an
over current. Therefore, use the main track programming 7.2.1.
7.3. Programming with Märklin® central stations
A direct programming possibility with a Marklin central unit (e.g
6021, Mobile Station®, Central Station®) is not possible due to
the missing DCC format. However, the most important properties
can still be changed.
SwitchPilot
The desired turnout numbers can be set directly with buttons.
Chapter 8.4 has more information. By means of the operating
mode switch you can chose between k83 or k84 mode (find
more 5.2.1).
SwitchPilot Servo
The desired turnout numbers can be set directly with buttons.
Chapter 8.4 has more information. The end positions and speeds
of all servos can be changed with the help of the input unit. See
Chapter 10.4.
For all options we recommend the use of the ESU Lokprogramer.

7.4. Programming with the ESU LokProgramer
Owners of the ESU LokProgramer device are able to set up the
SwitchPilot decoders very comfortably. Please always use the latest
computer software. It can be downloaded from our website
without any charge.
8. Address settings
The numbers of the outputs of the SwitchPilot can be assigned
freely – within limits. Unfortunately, the DCC norm is not
comprehendible that easily so therefore we would like to explain
it here in detail and also have you very thoroughly work through
Chapter 8 in case you are not yet familiar with it.
8.1. Turnout numbers
The outputs of the SwitchPilot are numbered:
The SwitchPilot offers a total of 6 outputs:
Outputs 1 through 4 are double transistor outputs, outputs 5
through 6 are servo outputs.
All available turnouts are numbered in all DCC or Märklin® digi-
tal systems. The number of available turnout numbers is limited:
Motorola®: Turnout numbers 1 – 256
DCC: Turnout numbers 1 – 2040 Servo outputs:
In DCC or Märklin® Digital systems the available turnouts are
numbered. The number of available choices are limited numbers:
Motorola®: Turnout numbers 1 - 256
DCC: Turnout numbers 1 - 2040
All turnout numbers are summarized by addresses. Turnouts 1 –
4 form the first address, turnouts 5 – 8 the second one, etc.
In order to function properly each SwitchPilot must know the
address that is assigned to it.
Programming
SwitchPilot
Since the SwitchPilot has a total of six outputs two addresses
can be assigned to it: address 1 is responsible for the transistor
outputs 1 – 4, address 2 is for the servo outputs 5 – 6.
This logic means that the outputs (and therefore the turnout
numbers) of the SwitchPilot always start at the beginning of an
address on one hand, and that all outputs stay together in one
block on the other hand.
8.2. Decoder address
The desired address is divided internally and put into CV 1 and
CV 9. Please never mix up decoder address and the turnout
number resulting from it. Most digital systems (incl. the ECoS)
show the turnout numbers instead of the decoder addresses on
the control panels.
SwitchPilot
The second turnout address for the servo outputs 5 - 6 of the
SwitchPilot is stored in CV 35 and CV 36.
8.2.1. Schedule of turnout numbers and addresses
The relation between turnout numbers and turnout addresses is
explained in Figure 12 on page 19: The desired turnout numbers
are derived from the chosen turnout address. Only the first 256
turnouts are accessible when using Motorola® central units.
It is not possible to assign turnout numbers above the limit of 4
to a SwitchPilot. For example, it would not be possible to assign
turnout numbers 4, 5, 6, or 7 to a SwitchPilot servo since those
are above the address limit. Please keep this in mind when
numbering your turnouts.
The table only shows the first 552 turnout numbers. 2040 turnouts
are possible in DCC operation. A complete table can be found
on our web site.

8.3. Factory settings
SwitchPilot
The four transistor outputs 1 to 4 react ex works to the turnout
numbers 1 to 4 with all outputs set to single pulse mode with
520 msec pulse duration. Address „1“ belonges to the
SwitchPilot.
The servo outputs 5 – 6 are deactivated ex works. There is no
second address to be allocated.
SwitchPilot Servo
The four servo outputs 1 to 4 react ex works to the turnout
numbers 1 to 4 and require 3.75 sec for a full movement with
both end positions being about 50% of the possible distance of
the starting point. Address „1“ belonges to the SwitchPilot
Servo.
8.4. Programming addresses with the programming button
You may program the addresses with the help of the programming
button without any complicated procedure on the programming
track. We recommend to proceed as follows:
You must use this method if you work with a Märklin® Motorola®
central unit (6021, Central Station®) or if you want to change
the addresses of the turnouts after installation of the decoder on
your layout.
8.4.1. First address for outputs 1 – 4
SwitchPilot SwitchPilot Servo
1. Select the turnout number on your digital system that you
want to assign to the first output of your SwitchPilot. Proceed
as per the instructions of your handheld throttle or your
command station as if you wanted to switch the respective
turnout (for ECoS users: refer to chapter 13 in the ECoS manual).
2. Turn on the power supply of your layout.
3. Press the programming button and hold it long enough until
(after about two seconds) the LED blinks as follows: short,
pause, short, pause, and so on.
4. You may now release the button, the decoder is in learning
mode.
5. Now switch the turnout you have selected in step 1 on your
handheld controller or your command station. It is immaterial
whether you switch from “straight” to “diverging route” or
vice versa.
6. Once the decoder has “understood” the address it will confirm
this by lighting up the LED for one second.
7. Then the SwitchPilot goes back to the normal operating mode
and the LED extinguishes.
Should you have programed another turnout instead of the first
one of the group of four the correct group will be automatically
detected and programed.
8.4.2. Second address for outputs 5 - 6
SwitchPilot
The second address is used for the (servo) outputs 5 and 6. Always
select turnout numbers at the beginning of a group of four, e.g.:
1 and 2, 5 and 6, 9 and 10, 13 and 14, etc.
1. Select the turnout number with your digital system that you would
like to assign to output 5 (first servo) of the SwitchPilot. Proceed
as per the instructions of your handheld controller or your
command station as if you wanted to switch this particular turn-
out (ECoS users please also refer to chapter 13 in the manual).
2. Turn on the power for your layout.
3. Press the programming button and hold it down until (after about
four seconds) the LED blinks as follows: short, short, pause, short,
short, pause, and so on.
4. Then you may release the button; the decoder is now in learning mode.
5. Switch the turnout you have selected in step 1 with your hand
held or the command station. It is immaterial if you switch from
“straight” to “diverging route” or vice versa.
6. If the decoder has “understood” the address it confirms this by
the LED lighting up for about one second.
7. The SwitchPilot then goes back to the normal operating mode
and the LED extinguishes.
