1. Getting started

How to use this manual

This manual gives step-by-step instructions for safe and correct assembly of the kit and fitting and connecting of the ready-built module, and operation. Before you start, we advise you to read the whole manual, particularly the chapter on safety instructions and the FAQ chapter. 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 kit or the ready-built module on to another person, please pass on the manual with it.

Intended use

The Booster-Link is designed to be operated according to the instructions in this manual with a digital model railway controlled by an mfx® central unit. Any other use is inappropriate and invalidates any guarantees.

The kit and the module should not be assembled or fitted by children under the age of 14.

Reading, understanding and following the instructions in this manual are mandatory for the user.

Caution:

The circuit contains integrated circuits. These are very sensitive to static electricity. Do not touch components without first discharging yourself. Touching a radiator or other grounded metal part will discharge you.

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.

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,

Page 19

English Booster-Link

§ 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.

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.

Booster-Link English

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.

Page 21

English Booster-Link

§ 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.

§ 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

Standard boosters used in digital model railway layouts controlled by mfx®-central units (e.g. mobile station or central station of Maerklin**), do not allow the transfer of the mfx®-feed back data across the isolation between the booster sections. For that reason vehicles that are in booster sections supplied by standard boosters cannot log in at the central unit.

The Booster-Link is used in combination with commercial standard boosters and transfers the mfx®-feed back data across the isolation between the booster sections. In layouts supplied by several boosters, you need one Booster-Link for each booster.

As usual in 3-rail systems the centre conductor has to be isolated between the booster sections when installing the Booster-Link. The outer conductors must not be isolated.

5. Technical specifications

6. Assembling the Booster-Link

You can skip this part if you have purchased a ready-built module or device.

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.

Value Colour rings 120 Ω brown - red - brown (gold) 470 Ω yellow - violet - brown (gold) 2,7 kΩ red – violet – red (gold) 3,3 kΩ orange - orange - red (gold) 47 kΩ yellow - violet - orange (gold) 330 kΩ orange - orange - yellow (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.

Page 24

Booster-Link English

Zener diodes

Zener diodes are used for limiting voltages. In contrast to "normal" diodes they are not destroyed when the limit voltage is exceeded.

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 1 nF 102 100 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.

Transistors

Transistors are current amplifiers which convert low signals into stronger ones. They have three contacts. As they are polarized, they have to be mounted in a certain direction.

The BD types have a flat housing (TO-housing) with the type designation printed on the front side. The metallic rear is unlabelled, on the PCB layout the rear is marked by a thick line.

Page 25

English Booster-Link

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. 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-controllers are ICs, which are individually programmed for the particular application. When leaving the manufacturer, their memories are empty. The programed controllers are normally only available from the circuit manufacturer.

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 resistors and the diodes. 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 IC-socket. It has to be mounted according to the marking on the PCB.

Continue the assembly with the capacitors, the electrolytic capacitors and the transistor.

Page 26

Booster-Link English

Caution:

Diodes, ICs, electrolytic capacitors and transistors 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 supply. In the worst case the whole circuit can be damaged. In any case, a wrongly connected part will not function.

Finally, solder in the terminal strip and insert the ICs into the soldered IC-socket.

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. Connecting the Booster-Link

Required number of Booster-Links

For each external booster supplying the mfx® layout you need one Booster-Link. In case one external booster supplies several booster sections one Booster-Link is sufficient.

Performing the booster sectionings

Isolate the centre conductor at the sectioning between the booster sections (if not already done). Please note: The outer conductors must not be isolated.

Connections

Make the connections according to the connections diagram (fig. 3) and the pin connections.

Booster-Link

Pin connections:

1 Centre conductor in the booster section supplied by the external standard

booster. In case one external booster supplies several booster sections it is sufficient to connect the Booster-Link to the centre conductor in one of the sections.

2 Outer conductor used for the connection of all boosters supplying the

layout.

3 Centre conductor in the booster section supplied by the booster integrated into

the central unit. Please note: Do not connect this connection to the centre conductor in a booster section supplied by another external booster. A safe data transfer cannot be guaranteed in this case. In case the booster integrated into the central unit is not in use to supply the layout, connect the connection directly to the booster output of the central unit (centre conductor).

Connexions:

1 Conducteur central du canton électrique alimenté par l’ampli standard externe. Si

un ampli alimente plusieurs cantons, il suffit de connecter le Booster-Link au

conducteur central de l’un des cantons. 2 Conducteur extérieur auquel sont connectés tous les amplis du réseau. 3 Conducteur central du canton électrique alimenté par l’ampli intégré de la

centrale. Attention : ne reliez pas cette borne au conducteur central d’un

canton alimenté par un autre ampli externe, la transmission des données en

serait affectée.

Si l’ampli de la centrale n’est pas utilisé pour alimenter la voie, reliez cette

borne directement à la sortie (conducteur centrale) de l’ampli de la centrale.

Aansluitingen:

1 Middengeleider in boosterdeel van de externe standaard booster. Versterkt de

booster meerdere delen, dan is het voldoende wanneer de booster link wordt

verbonden met de middengeleider van één van de delen. 2 Buitenste geleiders, waaraan ook de boosters voor de verzsterking van de

modelspoorweg zijn aangesloten. 3 Middengeleider in het boosterdeel, dat via de in de centrale geïntegreerde

booster wordt versterkt. Let op: verbind deze aansluiting niet met de

middengeleider van een boosterdeel, dat door andere boosters wordt versterkt.

Een goede dataoverdracht is in dit geval niet gegarandeerd.

Wanneer de booster, die in de centrale is geïntegreerd, niet voor de

versterking van de modelspoorweg wordt gebruikt, verbindt u de aansluitingen

direct met de boosteruitgang van de centrale (middengeleider).
