2. Safety instructions
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.
Page 25
English RCD-1
Electrical hazards
§ Touching powered, live components,
§ touching conducting components which are live due to malfunction,
§ short circuits,
§ connecting the circuit to another voltage than specified,
§ impermissibly high humidity,
§ 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.
§ 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.
Page 26
RCD-1 English
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.
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.
§ Observe correct polarity orientation of semi-conductors, LEDs
electrolytic capacitors and integrated circuits before soldering and
ensure that the solder time does not exceed 5 seconds, otherwise
components can be damaged.
§ Apply the soldering tip to the soldering spot in such a way that the part
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.
§ Do not move the component 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.
§ Cut the wires after soldering directly above the PCB solder side with
a side cutter.
Page 28
RCD-1 English
§ After placing the parts, please double check for correct polarity.
Check the PCB tracks for solder bridges and short circuits created
by accident. This would cause faulty operation or, in the worst
case, 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
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 RailCom decoders to the digital
control unit or to special receivers (so-called detectors). To transfer the
RailCom messages special RailCom boosters supplying the so-called
RailCom cutout have to be used.
Mode of operation
The RailCom detector RCD-1 is connected to a seperated rail section
and receives the RailCom messages applicated to the respective rail
section. These are possibly:
§ Addresses of the vehicle decoders in the rail section. The decoder´s
address is sent permanently.
§ CV-values of the vehicle decoders in the rail section. The CV-values
are sent only after a read out command (i.e. sent by the control
unit).
The RCD-1 verifies the signals it receives and sends the "clean" signals
via a special databus to special accessory devices (i.e. RailCom display
devices, units passing on data to a PC or to the digital control unit.)
Page 29
English RCD-1
Passing on and displaying data
There is no display integrated in the RCD-1. In order to display the
received data special RailCom display devices have to be connected
(e.g. single display device RCA-1 or 24-fold display device RCA-24).
These display devices can be mounted in those places of the railway
layout where needed. Instead of display devices, units passing on data
to a PC or to the digital control unit can be connected.
Detector and display device are connected via a special databus line. It
is possible to connect several detectors and several display devices to
one common databus line. To assign the detectors and the display
devices they get addresses from 1 to 24.
Example 1: To each of the six detectors RCD-1 is assigned both a single display
device RCA-1 and the 24-fold display device RCA-24. Changing the assignment is
done by just changing the devices´addresses (see example 2).
Example 2: Four single display devices are assigned to the detector RCD-1 #1 and
two to the detector RCD-1 #2. The detectors RCD-1 #1 to 6 are assigned to the
24-fold display device RCD-24.

6. Assembling the kit
You can skip this part if you have purchased a ready-built module.
Preparation
Put the sorted components in front of you on your workbench. The
separate electronic components have the following special features you
should take into account to prevent mistakes in assembling:
Resistors
Resistors reduce current. Their mounting orientation is of no
importance. The value of resistors for smaller power ratings
(under 5 W) is indicated through colour rings. Every colour
stands for another figure. The colour ring in brackets indicates
the tolerance of the resistor which here is of no importance.
Page 31
English RCD-1
Value Colour rings
1,5 Ω brown - green – black - silver (brown)
220 Ω red - red - brown (gold)
820 Ω grey - red - brown (gold)
1 kΩ brown - black - red (gold)
10 kΩ brown - black - orange (gold)
33 kΩ orange - orange - orange (gold)
47 kΩ yellow - violet - orange (gold)
270 kΩ red - violet - gelb (gold)
Diodes
Diodes allow the current to pass through in one direction only
(forward direction), simultaneously the voltage is reduced by
0,3 to 0,8 V. Exceeding of the limit voltage always will destroy
the diode, and allow current to flow in the reverse direction.
The diode type is printed on the body.
Diodes must be mounted in a given direction. The negative
end is marked with a ring. This is shown in the PCB layout.
Light emitting diodes (LEDs)
When operated in the forward direction the LEDs light. They
are available in several different versions (differing in colour,
size, form, luminosity, maximum current, voltage limits). The
longer lead of wired LEDs is always the anode (positive pole).
Light emitting diodes should always be connected via a series
resistor which limits the current and prevents failure.
Page 32
RCD-1 English
Capacitors
Among other things capacitors are used for filtering
interference voltages or as frequency determining parts.
Ceramic capacitors are not polarized, for that reason their
mounting orientation is of no importance. Normally they are
marked with a three-digit number which indicates the value
coded.
Value Number
100 nF 104
Electrolytic capacitors
Electrolytic capacitors are often used to store energy. In
contrast to ceramic capacitors they are polarized. One of the
two leads is marked with a minus sign which indicates the
mounting orientation. The value is given on the casing.
Electrolytic capacitors are available with different voltage
sustaining capabilities. Using an electrolytic capacitor with a
voltage sustaining capability higher than required is always
possible.
Integrated circuits (ICs)
Depending on the type, ICs fulfil various tasks. They are
polarized and therefore have to be mounted in a certain
direction. The most common housing form is the so-called
"DIL"-housing, from which 4, 6, 8, 14, 16, 18 or more "legs"
(pins) are arranged along the long sides. The mounting
orientation is shown by a semicircular or circular marking at
the end of the housing, which is also shown on the PCB
layout.
ICs are sensitive to damage during soldering (heat,
electrostatic charging). For that reason in the place of the ICs
IC sockets are soldered in, in which the ICs are inserted later.
Page 33
English RCD-1
The mounting orientation of the sockets is preset as well. The
markings on the PCB, the socket and the IC must lie on top of
each other after mounting.
Micro-Controler
Micro-controller are ICs, which are individually programmed
for the particular application. When leaving the
manufacturer´s works their memory is empty. The
programmed controller normally are only available from the
manufacturer of the circuit belonging to it.
Voltage regulators
Voltage regulators are ICs, which convert a variable, non
regulated input voltage in a constant output voltage. They are
produced in transistor housings with three connecting pins for
input, output and earth.
With voltage regulators in a SOT-housing (in form of a half
cylinder) the mounting orientation is given by the layout of
the connecting pins.
Terminal strips
Terminal strips are solder-in screw-type terminals. They provide a
solder-free and safe connection of the cables to the circuit, which can
still be seperated any time. When several terminal strips have to be
mounted side by side, they have to be put together before mounting.
Assembling the kit
Start the assembly with the lateral resistors and diodes and continue
with the vertical resistors and diodes R2, D4 and D5. First solder the
components on the solder side of the PCB and then cut the excess
wires with the side cutter, as short as possible.
Next solder in the capacitors, the electrolytic capacitors, the voltage
regulator and the IC-sockets. They have to be mounted according to
the marking on the PCB.
Page 34
RCD-1 English
!
!
Caution:
Diodes, electrolytic capacitors, voltage regulators and ICs must be
placed in the right direction! If you solder them the wrong way the
affected parts can be damaged when you connect the power. In the
worst case the whole circuit can be damaged. In any case, a wrongly
connected part will not function.
Next solder in the solder pins, the LED and the terminal strips. Put
together the terminal strips before mounting them.
Finally, insert the ICs into the soldered IC-sockets.
Caution:
Do not touch the ICs without first discharging yourself by touching a
radiator or other grounded metal parts. Do not bend the "legs" of the
ICs when inserting them into the sockets. Check that the markings on
the PCB, the socket and the IC show to the same direction.
Performing a visual check
Perform a visual check after the assembly of the module and remove
faults if necessary:
§ Remove all loose parts, wire ends or drops of solder from the PCB.
Remove all sharp wire ends.
§ Check that solder contacts which are close to each other are not
unintentionally connected to each other. Risk of short circuit!
§ Check that all components are polarised correctly.
When you have remedied all faults, go on to the next part.

7. Mounting the RCD-1
Separating the controlled rail sections
The rail section to be controlled by the RCD-1 has to be separated from
the remaining rails. It is sufficient to cut one rail, or with 3-rail systems
the middle conductor, at both ends of the section.
Connecting the RCD-1
Mount the RCD-1 into the lead-in wire from the booster to the rails. Be
sure to connect the two rail connections at the booster and the detector
in accordance when making the RCD-1´s connections to X1 and X2.
Connect a display device (e.g. RCA-1 or RCA-24) or a unit passing on
data to a PC or to the digital control unit to X3. Be sure to connect both
the connections A and A and the connections B and B of the RCD-1 and
the accessory device to each other.

control unit you have to drive at least one decoder on the
layout in DCC format.
flashes DCC-signal received, but no RailCom-Cutout detected.
The RailCom-Cutout is supplied by the booster and is
indispensible for feeding back data with RailCom. That is
the reason why the booster supplying the respective rail
section has to be RailCom-compatable.
Page 37
English RCD-1
8. Programming the RCD-1
By giving an identical address between 1 and 24 to the detector and
the accessory display device (or devices) you assign the devices to each
other. This enables the connection of several detectors and display
devices to one common databus line (and to minimize the cabling) and
the changing of the assignments any time.
The desired detector´s address has to be input at the accessory display
device. In order to assign the address properly make sure that during
the programming process only the detector to be programmed and the
accessory display device are connected by the lines A-A and B-B. You
achieve this by:
§ disconnecting the detector from the databus line (in connection
with other detectors) during the programming process and making
a temporary connection directly from the detector to the accessory
display device or
§ disconnecting all other detectors from the power supply during the
programming process.
To programm the RCD-1´s address follow these steps:
§ Disconnect the RCD-1 to be programmed from the power supply. In
case there are other detectors connected to the same databus line
you have to disconnect these from the power supply as well.
§ Program the address of the accessory display device as described in
the display device´s manual.
§ Bridge the two pins of the RCD-1´s programming connector JP1,
e.g. by putting on the jumper included in the package. Restore the
connection from the detector to the power supply. The LED on the
RCD-1 flashes. Be sure that the other detectors connected to the
same databus line are not connected to the power supply yet.
§ Program the RCD-1´s address at the accessory display device as
described in the display device´s manual. The RCD-1 indicates
receiving the address by quickly flashing the LED.
Page 38
RCD-1 English
§ After the LED goes out, disconnect the RCD-1 from the power
supply and take away the bridge on the two pins of the RCD-1´s
programming connector JP1.
§ If necessary disconnect the temporary connection between the
RCD-1 to be programmed and the accessory display device.
Restore the connection from the RCD-1 (and, if necessary, other
detectors connected to the same databus line) to the power supply.

9. Check list for troubleshooting
§ Parts are getting too hot and/or start to smoke.
Switch off the digital system immediately !
Possible cause: one or more components are soldered incorrectly.
à Perform a visual check.
§ The accessory display device does not show data.
Possible cause: The RCD-1 and the display device have not been
programmed to the same address. à Program the adresses of the
two devices anew. Be sure that only the RCD-1 to be programmed
and the accessory display device are connected to each other
during the programming process.
Possible cause: The connection A of the RCD-1 is connected to the
connection B of the display device (or the other way round).
à Exchange the connections A and B at one of the devices.
Possible cause: The booster connected to the controlled rail section
is switched off or does not supply the RailCom cutout. à Check
the booster.
§ When passing the sectioning point between two booster sections a
short circuit occurs.
Possible cause: The rail connections 1 and 2 (right and left / inside
and outside) at the booster or at the rails have been mixed
up. à Check and alter the connections.
