1. Getting started

How to use this manual

This manual gives step-by-step instructions for safe and correct fitting and
connecting of the decoder, and operation. Before you start, we advise you
to read the whole manual, particularly the chapter on safety instructions
and the checklist for trouble shooting. You will then know where to take
care and how to prevent mistakes which take a lot of effort to correct.

Keep this manual safely so that you can solve problems in the future. If
you pass the decoder on to another person, please pass on the manual
with it.

Intended use

The function decoder FD-R Extended is designed to be operated
according to the instructions in this manual in model building, especially
in digital model railroad layouts. Any other use is inappropriate and
invalidates any guarantees.

The function decoder FD-R Extended should not be mounted by
children under the age of 14. Reading, understanding and following the
instructions in this manual are mandatory for the user.

Required materials

For mounting and connecting the decoder you need:

 an electronic soldering iron (max. 30 Watt) or a regulated soldering

iron with a fine tip and a soldering iron stand,

 a tip-cleaning sponge,
 a heat-resistant mat,
 a small side cutter, a wire stripper and a pair of tweezers,
 electronic tin solder (0.5 mm diameter).

In order to connect decoders without soldered connecting wires you will
need wire. Recommended cross sections > 0.04 mm² for all
connections.

If you have a decoder without a soldered SUSI interface connector, you
might need a SUSI plug connector (e.g. item no. 70-01100).

For playing back the sounds you need:

 a loudspeaker with an impedance of min. 4 Ohm and a rated load-

carrying capacity of min. 0,1 Watt.

If you want to release switching operations automatically, e.g.:

 reed contacts 1 x closing contact (e.g. item-no. 84-53110)
 and / or Hall-sensors (e.g. item-no. 84-53210) and
 permanent magnets (e.g. neodymium magnets Ø 3mm, thickness

= 2mm, item-no. 84-53990).

If you want to use the output for the servo:

 one servo,
 a voltage supply for the servo (e.g. servo PCB item-no. 70-05900).

2. Safety instructions

Caution:

Integrated circuits (ICs) are inserted on the decoder. They are
sensitive to static electricity. Do not touch components without first
discharging yourself. Touching a radiator or other grounded metal part
will discharge you.

Mechanical hazards

Cut wires can have sharp ends and can cause serious injuries. Watch
out for sharp edges when you pick up the PCB.

Visibly damaged parts can cause unpredictable danger. Do not use
damaged parts: recycle and replace them with new ones.

Electrical hazards

 Touching powered, live components,
 touching conducting components which are live due to malfunction,
 short circuits and connecting the circuit to another voltage than

specified,

 impermissibly high humidity and condensation build up

can cause serious injury due to electrical shock. Take the following
precautions to prevent this danger:

 Never perform wiring on a powered module.
 Assembling and mounting the kit should only be done in closed,

clean, dry rooms. Beware of humidity.

 Only use low power for this module as described in this manual and

only use certified transformers.

 Connect transformers and soldering irons only in approved mains

sockets installed by an authorised electrician.

 Observe cable diameter requirements.
 After condensation build up, allow a minimum of 2 hours for

Page 6

tams elektronik

FD-R Extended English

dispersion.

 Use only original spare parts if you have to repair the kit or the

ready-built module.

Fire risk

Touching flammable material with a hot soldering iron can cause fire,
which can result in injury or death through burns or suffocation.
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 with this kit or the ready-built
module.

Caution:

Little children can swallow small components with sharp edges, with
fatal results! Do not allow components to reach small children.

In schools, training centres, clubs and workshops, assembly must be
supervised by qualified personnel.

In industrial institutions, health and safety regulations applying to
electronic work must be adhered to.

3. 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.

 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 electronic 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 quickly: holding the iron on the joints longer than necessary 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 solder flows into the joint, then remove the
soldering iron.

 The joint should be held still for about 5 seconds after soldering.
 To make a good soldering joint you should 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.

4. Operation overview

4.1. Modes of operation

Digital operation

The function decoder FD-R Extended is a multiple protocol decoder,
that can operate with and automatically recognise both DCC or
Motorola formats.

The number of addresses is dependant on the format being used:

 Motorola-Format: 255 addresses,
 DCC-Format: 127 Basis-addresses or 10.239 extended addresses.

In the DCC format the decoder can be driven in all speed levels (14, 28
or 128). In the Motorola format the decoder can be driven in 14 or 27
speed levels. Driving all 27 speed levels can be done only with central
units which support this mode (e.g. MasterControl). With central units
which allow 14 speed levels only, it is only possible to select every
second speed level.

Programming the decoders is done:

 in Motorola format by setting the registers,
 in DCC format by setting the configuration variables (direct

programming, DCC conform) or by POM (programming on main = main
track programming). Note: The configuration variables reserved for the
SUSI interface ## 897 – 1024 cannot be programmed by POM.

Analogue mode

The decoder can also be used in analogue model railway layouts run
with a D.C. speed control, and with restrictions with an A.C. speed
control. When putting the vehicle on the rails the decoder recognizes
automatically if it is run in analogue or digital mode and sets the
corresponding operation mode. The automatic recognition of the
analogue mode can be switched off.

Page 10

FD-R Extended English

Caution:

Old analogue driving transformers (e.g. models in a blue housing
from Maerklin**) are not suitable for use with digital decoders in analogue
operation! These transformers have been designed for the older supply
voltage of 220 V and, due to construction, generate very high excess
voltage impulses when changing the driving direction. When using them
with the modern supply voltage of 230 V too high excess voltage impulses
can occur, damaging electronic parts on the decoder. For that reason only
use driving transformers designed for a net voltage of 230 V.

Switching the function outputs on or off is not possible in analogue
mode. They can be programmed so that they are either switched on or
off in analogue mode. The effects set for the outputs are active in
analogue mode as well.

Outputs to be switched with F0 are switched on or off in analogue
mode according to the direction of travel with layouts run with a D.C.
speed control (not with an A.C. speed control), provided the return
conductor of the lamps or accessories is connected to the decoder´s return
conductor for all functions.

4.2. Function outputs

The decoder has six function outputs with a maximum current of
500 mA each, which are available to connect optional accessories (e.g.
lighting, smoke generator, electric coupling). The decoder´s maximum
total current is 1.500 mA.

Effects of all function outputs (AUX1 to AUX6)

 Switching on and off depending on the direction of travel.
 Flashing and double flashing. Both the frequency and the keying

ratio can be set. E.g. single and double flash lights or strobe lights.

 Kick function: It is possible to set the amplified function outputs so

that they get the full voltage first for up to 12,5 seconds and then

Page 11

tams elektronik

English FD-R Extended

are switched off. Example of use: For some types of electric couplings
you need the full voltage for decoupling and the voltage then siwtched off
to protect the couplings.

 Shunting light: You can program the outputs so that they are

switched on generally during shunting operation (to be switched with
F3 or F4). The dependence on the direction of travel will be nullified
for these outputs during shunting operation.

 Special function for speed level 0: It is possible to program one

function to switch off other functions or switch on special function
outputs at speed level 0. Example of use: In some locomotive sheds
it is customary that the tail lamps of parked locomotives have to be
temporally set at the front and the back.

Effects of the function outputs AUX1 to AUX4

 Dimming: 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.

 Dimming depending on the speed level: The voltage will be dimmed

depending on the speed level. This enables weak smoke generation during
halts or a switched off or dimmed cab lighting while the train is moving.

 MARslight (= light intensity going up and down): Example of use:

american locomotives with this type of lighting.

Servo output

The decoder has a connection to be used as a (third) switching input or
as an output to control a servo optionally. The voltage supply for the
servo cannot be provided by the decoder. For that reason an external
voltage supply (e.g. servo PCB item-no. 70-05900) is required.

The servo is controlled by:

 setting the end positions via CVs and controlling by pushing the

function keys ("on" = end position 1 , "off" = end position 2) or

 input of a value for the folding square by POM, which allows to

approach to any folding square.

4.3. Sound functions

SUSI interface

A SUSI module can be connected to the FD-R Extended and read out,
programmed and controlled via the decoder.

The function decoder transmits the function status and the speed level
set at the central unit, to the SUSI module. This affects the SUSI
module´s outputs depending on the speed level (e.g. motor sound).
The FD-R Extended allows the setting of the acceleration and braking
delay so that the functions depending on the speed level correspond to
the driving characteristics during accelerating and braking.

Integrated sounds

Four integrated sounds are available:

 train conductor´s whistle,
 door´s bleeping when closing,
 bell,
 signal horn.

4.4. Releasing the functions

The function outputs, the servo output and the integrated sounds can
be released by:

 pushing the function keys and / or
 automatically via the switching inputs (except SUSI module). The

switching inputs are released via external contacts, e.g. via reed
contacts or Hall sensors in combination with permanent magnets in
the rails.

The sounds of a connected SUSI module can be triggered by the
function keys as well as by the switching inputs that are assigned to
these function keys.

Page 13

tams elektronik

English FD-R Extended

Mapping of the outputs to the function keys

The mapping of the outputs to the function keys and the switching
inputs is arbritary. It is possible to assign several function keys and
switching inputs to one output.

Output DCC format MM format
AUX1 to AUX6 F0 to F28 F0 to F4 or

F5 to F9
(= F0 to F4 of a

2nd decoder address)

All function outputs can be switched inverted, i.e. when set to position
"on" the assigned function output will be switched off, when set to
position "off" switched on.

4.5. Automated processes

The control software in the function decoder allows you to automate
procedures and to reduce complex processes to one keystroke.

Dimming depending on the velocity

You can automatically switch functions depending on the velocity when
reaching a speed level defined in a CV. You assign an individual voltage
to the function outputs for the ranges of speed levels underneath and
above the defined speed level. This allows for example to switch on and
off the high beam light, to control the cab light or to influence the
intensity of the steam output.

Special function for speed level 0

By programming the special function for speed level 0 you can switch
on or off several function outputs and functions at the same time, you
otherwise had to switch singularly. This allows e.g. to switch off several
lights at once when parking a locomotive in the depot (e.g. front and
back lights, cab light and undercarriage light).

4.6. Feedback with RailCom**

RailCom is a log for bi-directional communication in digital model
railway layouts controlled in DCC-format. It allows e.g. the feedback of
the address and the CV values from the decoder to the digital central
unit or to special receivers (so-called detectors). The decoders must be
designed to send the RailCom messages.

When so programmed, the FD-R Extended sends

 on channel 1: continuously its (basic, extended or consist) address

(so-called RailCom broadcast datagramm) and

 on channel 2: a CV message after a DCC CV read-out command.

Sending RailCom messages is only possible in layouts with a DCC signal
on the rails. It is not possible to use the RailCom-function in a pure
Motorola environment.

4.7. Overload Protection

As soon as the maximum total current of the decoder is exceeded, the
decoder automatically temporally switches off, in order to protect itself
from overheating. This operation will be repeated until the overload has
been eliminated.

When the maximum current at one output is exceeded, but not the
maximum total current of the decoder, the overload protection of the
decoder is without effect, the output will be damaged.

Attention:

When a short circuit occurs that bypasses components on the decoder
either to each other or to track voltage, the overload protection is not
effective. Examples:

 contact between the decoder and the rails or metal parts of the

vehicle;

 contact between not-isolated decoder connecting wires and the rails

or metal parts of the vehicle;

 contact between accessories connected to the common return

conductor of the decoder and the rails or metal parts of the vehicle.

4.8. POM-update

POM-update is a procedure allowing to update the decoder´s firmware
(= specific decoder software) without dismounting the decoder or using
a specific device. POM-update is based upon programming on main
(POM) for the DCC format.

Preconditions for using the procedure are:

 Function decoder FD-R Extended from version 2.0.
 Digital central unit with PC interface providing the DCC format and

POM. Hint: As nearly every manufacturer of central units uses his
own procedure for programming on main, the POM-update can be
performed with the following central units only (status 01/2015):

MasterControl (Tams Elektronik)
Intellibox 1 (Uhlenbrock**)
CS2 (Maerklin**)

The current list of central units allowing to perform the POM-update
is available on our homepage.

 PC. The system software must support Java.
 Software "POM-Updater.exe": You will find it on the CD included in

delivery. It is also available on our homepage for free download.

You can download the current firmware version of the decoder free of
charge from our homepage. If you want to get information on new
firmware versions please subsribe to our newsletter on our hompage.
