Checking the package contents

Please make sure that your package contains:
one or five function decoders, depending on the version with or
without soldered connecting wires.

For mounting and connecting the decoder you need:

 a soldering iron with temperature control and a thin tip and a deposit

stand or a controlled soldering station

 a scraper, rag or sponge
 a heat-resistant pad
 a small pair of side cutters and wire strippers
 tweezers and flat-nose pliers if necessary
 electronic solder (preferably 0.5 to 0.8 mm diameter)

In order to connect a decoder without soldered connecting wires you
will also need wire. Recommended cross sections:

 > 0,04 mm² for the connections to the function outputs,
 > 0,05 mm² for the connections to the current collectors or slider

To bridge short current interruptions you need:

 an electrolytic capacitor with a capacity of 100 to 470 µF and a proof

voltage of minimum 25 V or

 a buffer circuit, e.g.

USV-mini 0.47 (capacity 0.47 F, item no. 70-02215 or 70-02216)
USV mini 1.0 (capacity 1.0 F, item no. 70-02225 or 70-02226)
USV mini 1.5 (capacity 1.5 F, item no 70-02235 or 70-02236).

To trigger switching operations automatically, you need:

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

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

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 dispersion.

Page 6

tams elektronik

FD-R Basic.3 English

 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 mount vehicle decoders.

Caution:

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

In schools, training facilities, hobby and self-help workshops, the
assembly, installation and operation of electronic modules must be
supervised by trained personnel.

In commercial facilities, the relevant accident prevention regulations
must be observed.

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 soldering iron with temperature control, which you set to

approx. 300 °C.

 Only use electronic solder with a flux.
 Never use soldering fluid or soldering grease when soldering

electronic circuits. These contain an acid that destroys components
and conductor paths.

 Solder quickly: Soldering for too long can detach solder pads or

tracks or even destroy components.

 Hold the soldering tip on the soldering point so that it touches the

wire and the pad at the same time. Add (not too much) solder
simultaneously. As soon as the solder begins to flow, remove it from
the soldering point. Then wait a moment for the solder to flow well
before removing the soldering iron from the soldering joint.

 Do not move the created solder joint for about 5 seconds.
 A clean, non-oxidized soldering tip is essential for a perfect soldering

joint and good soldering. Therefore, before each soldering, wipe off
excess solder and dirt with a damp sponge, a thick damp cloth or a
silicone wiper.

 After soldering, check (preferably with a magnifying glass) whether

connections or tracks have been bridged with solder by mistake. This
can lead to malfunction or destruction of components or, in the
worst case, the complete circuit. You can re-liquefy excess solder
with the clean hot soldering tip. The solder then flows from the
board onto the soldering tip.

4. Operation overview

4.1. Digital operation

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

4.2. Analogue mode

The function decoder can also be used in analogue model railway
layouts run with an D.C. speed control, but not with an A.C. speed
control.

Automatic analogue recognition

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 analogue recognition can
be switched off, e.g.

Page 10

tams elektronik

FD-R Basic.3 English

 if the decoder suddenly switches to analogue mode in digital

operation (e.g. as a result of interference voltages whose cause is
difficult to localise);

 if a value for the Packet Time Out is programmed to perform a

forced stop in case of track voltage failure or shutdown.

Switching the function outputs

Switching the function outputs on or off is not possible in analogue
mode. The outputs can be programmed with the digital central unit 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 that are switched depending on the direction are switched on
or off in analogue mode according to the direction of travel. When
operated in analogue d.c. layouts this applies only to lamps or accessories
where the return conductor is connected to the decoder´s common return
conductor for all function outputs.

4.3. Function outputs

The decoder has four function outputs with a maximum current of 300
mA each (F0f, F0r) or 100 mA each (AUX1, AUX2) for the connection of
additional accessories (e.g. lighting, smoke generator, electrical
coupling). Note: The maximum total current of the decoder is 700 mA.

Function mapping according to RCN-227

Assigning the functions to the outputs follows RailCommunity standard
RCN-227. It is possible to assign one or several outputs to each
function (F0 to F28, seperately for forward and backward motion for
each function). In addition, it is possible to assign another function as
an "OFF"-switch to the functions.

Page 11

tams elektronik

English FD-R Basic.3

This mode of function mapping allows to implement special features, e.g.:

 Switching on and off depending on the direction of travel.
 Shunting light: When switching to shunting mode the signals for

shunting locomotive are switched on and those for standard
operation switched off.

 Switching off the locomotive´s taillights when connecting wagons.

FD-R Basic.3 English

Programming the effects

Flashing
By assigning the flashing function to 2 outputs

and the "inverted switching" function to one of
the two outputs, an alternating flashing is
generated.

The flashing frequency is set separately for each
output.

CV programming

(CV 58-60, CV 101-104)

Kick function
The outputs first receive full voltage for a

maximum of approx. 25.5 seconds and are then
switched off. The kick time is set separately for all
outputs.

Example of use: Some types of electrical couplings
require full voltage to decouple. However, the
voltage should be switched off after uncoupling in
order to protect the couplings.

CV programming

(CV 58-60, CV 99)

Dimming
To reduce the voltage at the output.

Example of use: The lights of older vehicles
intended for analogue operation can be dimmed
and then do not need to be replaced after the
decoder has been installed.

4.4. Triggering the actions

The function outputs are switched on and off and the shunting mode is
(de)activated:

 through the assigned function(s) and / or
 automatically via the switching input. The switching input is triggered

via external contacts, e.g. via reed contact or Hall sensors in
combination with permanent magnets in the track.

Assignment of the actions to the functions (Function Mapping)

The assignment of the actions controlled by the decoder to the
functions is freely selectable, each separately for forward and reverse
travel.

4.5. Feedback with RailCom

®

The function decoder FD-R Basic.3 is a RailCom transmitter and meets
the requirements of the RailCommunity standard RCN-217 "RailCom
DCC feedback protocol" (status 01.12.2019) for mobile decoders
(vehicle decoders). RCN-217 has been published on:
www.railcommunity.org

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

Background information: RailCom-messages of vehicle decoders

In channel 1, the vehicle decoders transmit their DCC address after

Page 14

tams elektronik

FD-R Basic.3 English

each DCC command directed to any vehicle decoder. Channel 1 can be
set "dynamically", i.e. the decoder will only transmit its address in
channel 1 until a DCC command is directed to it. This frees the
channel for the messages of other decoders to which no command has
yet been sent or which are not yet known to the system.

In channel 2, vehicle decoders send their feedback as soon as a DCC
command is sent to their address.

Background information: Dynamic RailCom information

"Dynamic information" mean contents of CVs (RailComCVs 64-127)
which change during operation (e.g. real speed, reception statistics,
tank content). If needed, they are sent by the decoder spontaneously.

The reception statistics are kept by the vehicle decoder, and reported
as number of faulty data packages in relation to the total number of
data packages. These statistics allow conclusions on the transmission
quality between vehicle and rails.

The function decoder FD-R Basic.3 can send the following dynamic
RailCom information:

 reception statistics

6. Connections

Avoid irreparable damage!

Observe the following instructions to avoid damage to the decoder:

1. No conductive connections to metal parts or rails!

Avoid all conductive connections between the decoder or consumers
connected to the return conductor for all functions on the one hand,
and metal parts of the vehicle or the rails on the other hand.
Connections are caused e.g. by insufficiently insulated connecting
cables (even at the stripped ends of unused connecting cables!) or
insufficient fastening and insulation of the decoder or consumers.
Danger of short circuit!

2. Do not connect the return conductor to vehicle ground!

You should under no circumstances connect the decoder´s common
return conductor for all function outputs to vehicle ground. Risk of
short circuit!

3. Exclude overload!

Before connecting lights and additional accessories, check that the
current is below the maximum permissible values and that the total
current is not exceeded. If the permissible current is exceeded, the
decoder may be damaged during commissioning.

4. Not for use in analogue AC systems!

The FD-R Basic.3 is only approved for analogue operation with DC
driving transformers. If it is used in analogue AC systems, irreparable
damage to the components of the decoder may occur.
