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.
DCC Motorola (MM)
Number of addresses
127 basic addresses or
10.239 extended addresses
255
Speed level modes
14, 28 or 128 14
Programming configuration variables

or POM (programming on main = main track programming)
registers

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.

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.
CV programming
(CV 47-50)

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.
Actions

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:

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.

6.2. Connecting accessories to the outputs

Caution:
The maximum current of the accessory must not exceed the maximum current of the output to which you connect it. The output may otherwise be irreparably damaged!
Disconnect any existing diodes in the leads to the lamps, otherwise the lamps might not light. Connect the lamps and the accessories to the function outputs of the decoder. If the lamp or the accessory is already connected with one side to vehicle ground, the connection is complete. If not, connect the second side of the lamp or the accessory to the decoder´s common return conductor for all function outputs.
You find the factory (default) settings in the lists with the connector pin assignments (page 18). You can assign the outputs to the function keys voluntarily by setting the configuration variables.

6.3. Connecting LEDs to the function outputs

The decoder´s function outputs switch respective to the decoder ground. For that reason you must connect the cathodes (-) of the LEDs to the function outputs and the anodes (+) to the decoder´s common return conductor for all function outputs (RC).
Caution:
You must always operate LEDs via a series resistor! Otherwise LEDs will be destroyed when put into operation or have a significantly reduced duration of life. If you do without a series resistor, other components take over their function (e.g. rails, wheels, current collectors). This can lead to a change in the digital signal and thus to interference in digital operation.
Determine the required resistance value for the peak value of the working voltage available at the return conductor (RC).
Determining the peak value of the working voltage
with regulated boosters:
output (= track) voltage of the booster - 1 V*
with not regulated boosters or analogue driving transformers:
(1,4 x the nominal voltage specified on the transformer) - 1 V*
* 1 V gets "stuck" in the rectifier of the decoder.
Serial connection of LEDs
When you want to connect several LEDs to one output you can switch them in series via a common series resistor. The current consumption is max. 20 mA for all LEDs, depending on the series resistor´s value. The maximum number of LEDs to be connected in series results from
Peak value of the operating voltage
- sum of the forward voltages of all LEDs > 0
The advantage of this solution is the low current consumption.
Page 20
tams elektronik
FD-R Basic.3 English
In order to determine the necessary series resistor for a serial LED´s connection first add the forward voltages of all LEDs. The forward voltages depend on the lighting colour and should be given in the technical specifications. In case there is no manufacturer information available, you can take as a basis 4 V for white and blue LEDs and 2 V for yellow, orange, red and green LEDs.
The remaining voltage has to be "eliminated" by a resistor. The formula for the calculation of the resistor is:
required RV [Ohm] = ( UB [V] – ∑ UF [V] ) / (IF [mA] x 0.001)
UB = operating voltage (peak value) | ∑ UF = sum of the forward voltages of all LEDs IF = current with max. luminosity
Parallel connection of LEDs
Alternatively, you can connect several LEDs in parallel, each via a series resistor of its own. The current consumption is max. 20 mA for all LEDs, depending on the series resistor´s value. The maximum number of LEDs to be connected in parallel results from
maximum current at the output
- sum of the current consumption of all LEDs > 0
Advantageous with this solution is that the LEDs already lighten when their forward voltage has been reached (2 to 4 V, depending on the fluorescent colour), which makes this solution suitable for analogue mode. Disadvantageous is the high current consumption.
The formula for the calculation of the resistor is:
required RV [Ohm] = ( UB [V] – UF [V] ) / (IF [mA] x 0.001)
UB = operating voltage (peak value) | UF = forward voltage of the LED IF = current with max. luminosity
In order to save current, you can limit the LEDs´current consumption to 10 mA, which normally does not cause a visible loss of luminance.
Page 21

English FD-R Basic.3

6.4. Connecting inductive loads

When connecting inductive loads (e.g. TELEX couplings, relays or other accessories with coils), you should switch a free-wheeling diode (e.g. 1N400x) in parallel, in order to avoid damage at the output. Check to connect the anode of the diode to the function output.
Connecting accessories via a relay
When you want to switch an accessory / accessories via the decoder, which connection would lead to exceeding the maximum current at the output or of the decoder, you can switch the accessories via a relay (e.g. 1xUm 1A 12V, item-number84-61010) and connect them directly to the vehicle´s current collector.
The current consumed by the relay depends on its type. The relay named in the example needs approx. 100 mA.
As described in the section "Connecting inductive loads" you should switch a free-wheeling diode (e.g. 1N400x) in parallel to the relay.

FD-R Basic.3 English

6.5. Connecting the switching input

The switching input switches against decoder ground and can therefore be connected to all (external) circuits that can be used to establish a ground connection. It is possible, for example, to connect reed contacts or Hall sensors which establish the ground connection as soon as they enter the magnetic field of a permanent magnet.
Connection of a reed contact
You can use both normally open contacts and changeover switches (changeover contacts).
Note: The glass bulbs of reed contacts are sensitive to
mechanical damage!
Connect reed contacts to the switching input and the ground connection of the decoder (GND). Reed contacts are not polarized, so you can assign the two connections as you wish.

6.6. Connecting a buffer capacitor/buffer circuit

In sections with bad contact to the rails (e.g. when running over turnouts) or with a (e.g. construction-related) bad current consumption of the vehicle, the power supply of the decoder can be interrupted briefly. In analogue mode the effects are usually small, but in digital mode massive disturbances can be the result: e.g. flickering of the lights up to automatic switching to analogue mode. This can be remedied by connecting a backup capacitor or a special buffer circuit.
Connection of a backup capacitor
The capacitor must have a capacity of at least 100 µF and a maximum of 470 F and a proof voltage of at least 25 V. Pay attention to the correct polarity when connecting!
Fig. 5: Connection of a backup capacitor ("buffer electrolytic capacitor")
Connection of a buffer circuit
The capacity of buffer circuits is considerably larger than that of buffer capacitors (e.g. UPS-mini with 0.47 F, 1.0 F or 1.5 F). Use a buffer circuit according to RCN 530 that can be connected without a control line, e.g. UPS-mini, part no. 70-0221x, 70-0222x, 70-0223x.
When connecting, follow the instructions for the buffer circuit.

6.7. Fixing the decoder

After having finished all connections you should fix the decoder, to avoid short circuits by contact to metal parts of the vehicle, for example. You can use double sided adhesive tape for it or a decoder holder (item number70-01810 or 70-01820), for example.

7. Programming

Programming with DCC central units
You can program the configuration variables (CV) of the decoder from the digital central unit, you can use main track programming as well. See the chapter in the manual of your central unit where the byte wise programming of configuration variables (CVs) (Direct programming) and main track programming (POM) are explained.
Register programming is not supported by the decoder. With DCC central units that allow only register-programming it is not possible to program the FD-R Basic.3.
Programming with Motorola central units
In Motorola format the settings are saved in registers. The registers have the same numbers as the configuration variables (CVs) for the DCC format.
Please note: If you use a central unit for both DCC and Motorola format it is recommended to program the decoder in the DCC format. After having finished programming the decoder it is possible to control it in Motorola format as well.
Please note: You should connect a lamp or a LED to at least F0f or F0r before starting to program the decoder with a Motorola central unit, as the decoder shows the status of the programming by flashing the lighting connected to these outputs. The flashing frequency shows, which input the decoder expects:
Slow flashing Fast flashing
Number of the register to be programmed
Value of the register to be programmed
Page 27
tams elektronik
English FD-R Basic.3
Put the vehicle on a track oval or a track section connected to the central unit’s track output (not to the connection for the programming track). Make sure no other vehicle than the one you intend to program is set on the track as the decoder inside this vehicle might be programmed as well.
Starting

1. Enter the number of the
register as a Motorola-address.
If necessary: with a leading "0".
2. Operate the direction switch. Lighting flashes faster.
3. Enter the value you want to set into the register
(as Motorola-address).
4. Operate the direction switch. Lighting flashes more slowly.
If necessary: repeat steps 1 to 4
for all registers to be
programmed.
Push button "stop".

8. Configuration variables and registers

The following lists shows all configuration variables (for the DCC format) and registers (for the Motorola format), that can be set for the function decoder.
Registers and configuration variables (CVs) have identical numbers, they are shown in the tables in the column "No.". The defaults are those values set in the state of delivery and after a reset.
Please note: With variables destined to set several parameters, the input value has to be calculated by adding the numerical values assigned to the desired parameters.

For DCC format only:
Extended addresses 32
Tip: If the use of extended addresses is activated in CV 29, the decoder does not react to signals in Motorola format!
Example: CV 29 = 0 Direction = "Standard". 14 speed levels . Automatic analogue recognition = "off". RailCom ="off". Basic addresses.
Example: CV 29 = 46 Direction = "Standard". 28 or 128 speed levels in DCC mode. Automatische Analogerkennung = "on". RailCom = "on". Extended addresses.

8.2. Function mapping

The assignment of the actions controlled by the decoder
switching the function outputs on and off(de)activation of the special function "Shunting mode / Shunting
light" (SM)
to the functions is carried out according to RailCommunity standard RCN-227. Note: Function mapping is not possible with pure Motorola central units.
To get access to the corresponding memory area (the so-called "page"), the values for "Function mapping" must be set in CV 31 and 32 (= default values).

According to RCN-227, eight configuration variables (CVs) are assigned to each function (F0 to F28) (four each for forward ("f") and reverse ("r"). Six of them are used for the function decoder FD-R Basic.3 (3 for forward and 3 for reverse):
2 CVs for the outputs (F0f, F0r, AUX1 and AUX2): Here you set
which outputs are switched with the function.
1 CV for the special function "Shunting mode / Shunting light" (SM):
Here you set which function is used to activate the shunting mode.
Switch-off function: Here you can define a function with which you
can switch off the actions assigned to the function when switching on. The value "255" determines that the actions are switched off
with no function.

9. Check list for troubleshooting

Parts are getting very hot and/or start to smoke.
Disconnect the system from the mains immediately!
Possible cause: one or more connections are soldered incorrectly. Check the connections.
Possible cause: Short circuit between the decoder or accessories connected to the retrun conductor for all functions and metal parts of the locomotive or the rails. Check the connections. A short circuit can result in irreparable damage.
Problems with switching of the functions
An accessory / a light does not react to switching commands.
Possible cause: The accessory is defective or incorrectly connected. Check the accessory / the connections.
Possible cause: The output is defective (e.g. due to overload or short circuit). Send in the decoder for check / repair (with costs).
The lighting goes on and off when the speed levels are turned up or
the lighting cannot be switched on or off. Possible cause: The speed mode of the decoder and the digital control
unit do not correspond. Example: The central is set to the mode 28 speed levels, but the decoder to the mode 14 speed levels. Change the speed mode at the central and / or at the decoder.
Page 49
tams elektronik
English FD-R Basic.3
Problems with switching via the switching input
After passing a permanent magnet in the rails no action is activated.
Possible cause: The reed contact or the Hall sensor has been mounted incorrectly. Check the connections.
Possible cause: The distance to the magnet is too large or the magnet is too weak. Alter the position of the magnet (if possible) or use a stronger one.
Possible cause: The magnet has been mounted incorrectly polarized. Alter the mounting direction.
Possible cause: The assignment of the function to the switching input is wrong or the minimum switch-on time is too short. Check the inputs in CV 62 and 97.
Problems in analogue mode
The decoder does not react in analogue mode.
Possible cause: The analogue mode is switched off. Alter the value for CV 29.
The decoder does not switch to analogue mode (or switches over
although it is still digitally controlled). Possible cause: The value in CV 11 is set too high or too low. Alter
the value and check the settings in operation.
