Fire risk
Touching flammable material with a hot soldering iron can cause life-
threatening fire, burns and toxic smoke. Connect your soldering iron or
soldering station only when actually needed. Always keep the soldering
iron away from inflammable materials. Use a suitable soldering iron
stand. Never leave a hot soldering iron or station unattended.
Thermal danger
A hot soldering iron or liquid solder accidentally touching your skin can
cause skin burns. As a precaution:
§use a heat-resistant mat during soldering,
§always put the hot soldering iron in the soldering iron stand,
§point the soldering iron tip carefully when soldering, and
§remove liquid solder with a thick wet rag or wet sponge from the
soldering tip.
Dangerous environments
A working area that is too small or cramped is unsuitable and can cause
accidents, fires and injury. Prevent this by working in a clean, dry room
with enough freedom of movement.
Other dangers
Children can cause any of the accidents mentioned above because they
are inattentive and not responsible enough. Children under the age of
14 should not be allowed to work the module.
Little children can swallow small components with sharp edges. Life
threatening! Do not allow components to reach small children.

EMC declaration
This product is developed in accordance with the European standards
EN 55014 and EN 50082-1, tested corresponding to the EC - directive
89/336/EWG (EMVG of 09/11/1992, electromagnetic tolerance) and
meets legal requirements.
To guarantee the electromagnetic tolerance you must take the
following precautions:
§Connect the transformer only to an approved mains socket installed
by an authorised electrician.
§Make no changes to the original parts and accurately follow the
instructions, circuit diagram and PCB layout included with this
manual.
§Use only original spare parts if you have to repair the module.
Operation overview
The decoder is designed for operation in Motorola II format and can be
adjusted to one of 255 addresses. It evaluates the digital data sent by
the central unit to its address and transmits it to the connected loads.
In Motorola I format the programming of the parameters and the
controlling of the functions is reduced.
Function outputs
The decoder has seven function outputs which can be switched on and
off via the function key „function“ and / or the auxiliary function keys
F1 to F4. They are available to connect optional accessories (e.g.
lighting, smoke generator, sound module, electric coupling). The
function outputs X4 and X5 as well as X7 and X8 are switched together.
The set states of the function outputs are saved. Even if the decoder is
without current for a longer time, the states are set when the decoder
is switched on again.

English FD-4
Page 28
Assignment: You can assign the function keys to the function outputs
X6, X9 and X10 freely. It is possible to assign several function keys to
one function output. Function outputs that are assigned to the function
key „function“ can be switched according to the direction of travel.
Example of use: The lighting of a shunting locomotive is assigned both
to the function key „function“ as to the function key F1. In shunting
operation you switch the lighting via F1 and in standard operation
according to the direction of travel via „function“.
The function outputs X4 and X5 are assigned firmly to the function F2,
the outputs X7 and X8 to the function F1.
Dimming: The function outputs X6, X9 and X10 can be dimmed
individually.
Example of use: The electric bulbs of older vehicles made for analogue
operation can be dimmed and thus must not be exchanged after the
mounting of the decoder.
Example of use: The front lighting is assigned to two different function
outputs. Via one function key you can switch the standard lighting, via
another the long distance lighting.
Check back of the address
In the programming mode you can query the address. The address is
transmitted coded by the flashing of the lighting of the vehicle.
Online-programming
The address and all functions can be programmed online. This means:
§In order to start the programming mode and to set the desired
(new) address, it is not necessary to enter the present address.
§In the programming mode the function to be set is active. This
makes it easier to assign the outputs to the function keys. The
dimming can be altered via the speed knob. As soon as it is set as
desired, they can be saved directly (online).

FD-4 English
Page 29
Restrictions in Motorola I format
In Motorola I format it is possible to set the address and to assign the
function outputs to the function key „function“. It is not possible to
perform a reset and to query the address. The functions F1 to F4
cannot be switched.

Required tools and consumables
Make sure you have the following tools, equipment and materials ready
for use:
§an electronic soldering iron (max. 30 Watt) with a fine tip,
§a soldering iron stand,
§a tip-cleaning sponge,
§a heat-resistant mat,
§a small side cutter, wire stripper and a pair of tweezers,
§tin solder (0,5 mm. diameter),
§wire (diameter: >0,1 mm²).
Safe and correct soldering
Caution:
Incorrect soldering can cause dangers through fires and heat. Avoid
these dangers by reading and following the directions given in the
chapter Safety instructions. If you have had training in soldering you
can skip this chapter.
§Use a small soldering iron with max. 30 Watt. Keep the soldering tip clean
so the heat of the soldering iron is applied to the solder point effectively.
§Only use tin solder with flux.
§When soldering electronic circuits never use soldering-water or
soldering grease. They contain acids that can corrode components
and copper tracks.
§Solder fast: long soldering can destroy components and can
damage copper tracks or soldering eyes.
§Apply the soldering tip to the soldering spot in such a way that the wire
and the soldering eye are heated at the same time. Simultaneously add
solder (not too much). As soon as the solder becomes liquid take it
away. Hold the soldering tip at the spot for a few seconds so that the
tin solder finds its way, then remove the soldering iron.

FD-4 English
Page 31
§The joint should be held still for about 5 seconds after soldering.
§To make a good soldering joint you must use a clean and
unoxidised soldering tip. Clean the soldering tip with a damp piece
of cloth, a damp sponge or a piece of silicon cloth.
§After soldering check (preferably with a magnifying glass) tracks for
accidental solder bridges and short circuits. This would cause faulty
operation or, in the worst case, permanent damage. You can
remove excess solder by putting a clean soldering tip on the spot.
The solder will become liquid again and flow from the soldering
spot to the soldering tip.
Mounting the function decoder
Open the vehicle housing. Locate the position for the decoder.
Solder the connections from the rail current collectors at the points X2
and X3. The assignment of the connecting wires is not important.
Connecting the lighting and other accessories
Follow the connection diagram fig. 1.
Disconnect any existing diodes in the leads to the lamps.
Connect the lamps and other accessories to the function outputs of the
decoder. You can assign the function outputs X6,X9 and X10 to the
function keys freely while programming the decoder. The function
outputs X4 and X5 are always switched together via the function key
F2, the outputs X7 and X8 together via the function key F1.
If you want to use the decoder factory settings, you have to connect
the lighting and the accessories as follows:
Front lighting: X9
Back lighting: X6
Accessory (-ies) to be switched via F1: X7 and X8
Accessory (-ies) to be switched via F2: X4 and X5
Lighting independent of direction of motion: X10

!
If you want to connect an accessoriy with a current consumption of
more than 500 mA you must connect the two outputs in parallel (fig. 1a
and 1b, connection to X4 and X5).
Caution:
The current consumption of all connected accessories may not exceed
1.500 mA!
You can connect the second side of the accessories either to the return
conductor for all functions (point X1) or to vehicle ground. If connecting
the accessory to vehicle ground you must solder in a diode.
Caution:
The return conductor for all functions (point X1) must under no
circumstances be connected to vehicle ground. Possible short circuit!
The decoder will be damaged in operation.
Tip: If the second side of the lamps is connected to vehicle ground the
lamps often flicker in operation. You can avoid the flickering of the
lamps if you connect the second side to the return conductor for all
functions (point X1) instead of vehicle ground.
Caution:
If you connect the loads to the return conductor for all functions (point
X1), the load must be insulated. The loads must not make contact with
metal parts of the locomotive or the carriage. Possible short circuit! The
decoder will be damaged in operation.
Advice: Some accessories can not be checked for operation by
switching on and off in short invervals (e.g. smoke generators). If you
have connected accessories like these to the function outputs of the
decoder it is recommended to connect a lamp in parallel to the
accessory during the programming of the decoder.

Connecting the LEDs
The function outputs of the function decoder switch against decoder
ground. For that reason you must connect the cathode (-) of the LED to
the output of the relevant function.
Caution:
If you use light-emitting diodes (LEDs) you must always operate them
via a series resistor.
LEDs are available in many different models. There are LEDs with 2-5
mA, but also LEDs with 15-30 mA power consumption. The series
resistor limits the current flow of the LED and will need to be calculated
for each model. Ask for the max current rating when buying your LEDs.
You can connect several LEDs in parallel to each output. In this case every
LED must have a series resistor of its own. If you connect several LEDs to
one output in series, only one series resistor is needed. The number of
LEDs connected in series to one output depends on the digital voltage.
You can determine the number of the LEDs that can be connected in
series to one output from the following formula:
(number of LEDs + 2) x 1,5 < digital voltage
Fixing the function decoder
After completing all connections fix the function decoder with double-
sided adhesive tape, for example.

Programming the function decoder
You can make the following adjustments from the central unit without
intervention at the vehicle:
1. Decoder address
2. Assignment of the function outputs to the function keys
3. Dimming the function outputs
Accessing the programming mode
Put the vehicle on the layout and reset the central unit (by
simultaneously pushing the buttons "stop" and "go" for some time). Set
the function key "function" of the central unit to "off". Enter the address
"78" at the central unit.
Attention:
It does not matter if you have already saved another address. You
always have to enter the address "78" to access the programming mode.
If you put the vehicle for programming on the layout take off all other
vehicles with deocders with online-programming. If not you programm
these vehicles as well.
Push the "stop" button at the central unit. Next, operate the direction
switch and hold it in that position while briefly pushing the "go" button.
As soon as the lamps of the vehicle flash (after approx. 2 seconds) the
decoder is in the programming mode and you can release the direction
switch.
Notice: Some types of central units do not allow you to access to the
programming mode when the Motorola II format is set (e.g.
Intellibox** from Uhlenbrock). In order to start the programming
mode these central units must be set to Motorola I format for the
address “78”. As soon as the decoder is in the programming mode, the
central unit must be set back to Motorola II format.

FD-4 English

Starting from this menu level you can:
Without any further inputs: Set the address and the functions.
After pushing the function key F1: Query the address.
After pushing the function key F2: Perform a decoder reset.
You can finish the programming mode at any time by disconnecting the
vehicle (pushing the button „stop“ or taking the vehicle from the track).
Setting the decoder address
You are in the menu point „Setting the decoder address“ when all
lighting connected to the function outputs flash regularly. Enter the
desired address. You do not need to enter the old address. Confirm
your setting by switching the function key „function” on and off once.
After the taking-over of the decoder address the regular flashing of the
connected lighting stops and the decoder proceeds immediately to the
programming of the first function output.
Setting the function outputs
Now the function outputs X9, X6 and X10 are programmed one after
the other. The function keys are assigned in succession, and the
dimming function is set for each output.
Assigning the function keys: While the programm continuously
switches the ouput to be programmed on and off (and the lighting
connected to the output flashes) switch on the functions key(s) F1 to
F4 on your central unit with which you want to switch on the output in
later operation. You can assign several function keys to one output of
the decoder.
If you want to switch the function output in operation via „function“ you
have to make the following settings:
Speed level 1 : Output will be switched on during backwards motion.
Speed level 2 : Output will be switched on during forward motion.
Speed level 3 : Output will be switched on independent of the direction
of motion.

English FD-4
Page 36
Advice: On the Märklin* Central Unit 6021 the speed levels 1,2 and 3
correspond to the settings 20, 40 and 60.
Confirm your settings by switching the function key „function“ on and
off once.
Setting the dimming function: The dimming function is set via the
speed knob. If lamps are connected speed level 0 stands for minimal
voltage at the output to be set and speed level 14 (250 on Märklin*
Control Unit 6021) maximal voltage. Confirm your setting by switching
the function key „function“ on and off once.
Repeat the assignment of the function keys and the setting of the
dimming function for the other function outputs. You can skip the
programming of an output that is not occuppied by switching on and off
the function key „function“ two times.
As soon as all functions are set, the programming is closed and you
have to disconnect the vehicle.
Querying the decoder address
You get to this programming step only by operating the function key F1
on the top menu level after having started the programming mode. The
lighting of the vehicle now starts to flash. Two flashing signals
interrupted by a short stop transmit the coded address. After a longer
pause the two flashing signals are repeated. You’ll find the meaning of
the flashing signals in the appendiix. You get back to the standard
operation by disconnecting the decoder.
Performing a decoder reset
You get to this programming step only by operating the function key F2
on the top menu level after having started the programming mode. By
operating the function key F2 you restore the factory settings (and all
other settings are deleted). Then the decoder continues automatically
in standard operation.
