Printing the manual
The formatting is optimised for double-sided printing. The standard page size is DIN A5. If you prefer a larger display, printing on DIN A4 is recommended.

1. Getting started

This manual gives step-by-step instructions for safe and correct assembly of the kit and fitting and connecting of the adapter, 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 kit or the ready-built adapter on to another person, please pass on the manual with it.

1.1. Contents of the package

one adapter PCB
one 22-pole plug connector for use as MTC-interface

1.2. Accessories

To assemble the kit you will 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)

Connection cables
The use of stranded wire is recommended for making the connections. Stranded wires consist of several thin individual wires and are therefore more flexible than rigid wires with the same copper cross-section. Recommended cross- sections:
m 0.04 to 0.10 mm² (depending on the load)

1.3. Intended use

The adapter is intended for use in model construction, especially in model railway layouts, according to the specifications in the manual. Any other use is not in accordance with the intended use and will result in the loss of the warranty claim. Intended use also includes reading, understanding and following all parts of the instructions. The adapter is not intended to be used by children under the age of 14.

2. Operation overview

The adapter is used to upgrade vehicles with a PluX or MTC interface interface. There is a 22pole socket soldered on to the adapter PCB which is used to insert the plug connector of the decoder-sided PluX interface. In order to connect the adapter to the the decoder-sided MTC interface, the extra 22-pole plug connector has to be inserted into the adapter PCB.

2.1. Background information

PluX interfaces for different gauges
PluX-interfaces have 12, 16 or 22 connector pins and that way are suitable to be mounted in t vehicles of different gauges (or with varying space requirements). The assignment of the different versions allows to insert a plug connector with 12 or 16 connector pins into a socket k with a larger number of connections.
Index-pin
For both types of interfaces the position of an index-pin which should not be used has been e defined. By means of the index-pin you can distinguish the direction for inserting the plug connector into the socket. At the position of the plug connector in question the pin should be s removed.

2.2. Mounting versions

The (PluX- or MTC-) vehicle decoder can be inserted as well from the top as from the bottom a into the adapter PCB. The assignment of the PCB´s contacts depends on the direction of t inserting the decoder.

2.3. Mounting versions for PluX decoders

2.4. Mounting versions for MTC decoders

3. Assembling the kit

3.1. 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.

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 o precaution: r use a heat-resistant mat during soldering, t always put the hot soldering iron in the soldering iron stand, k point the soldering iron tip carefully when soldering, and le 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 s 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
m not responsible enough. Children under the age of 14 should not be allowed to work with this
kit or the ready-built device.

⚠ 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.

3.2. 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 ik 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 r soldering. Therefore, before each soldering, wipe off excess solder and dirt with a damp t 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 le 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 s e tip. tam

3.3. Soldering on the cables

Solder the connecting cables on the top side of the adapter PCB. Observe the different assignments for PluX and MTC interfaces and the different mounting versions.
It is recommended to use cables of different colours according to NEM 658 or NEM 660 in order to avoid mistakes when connecting the adapter PCB.

Perform a visual check!

After having soldered the cables you should perform a visual check and remedy defects.

Check if soldering joints closely adjoining are connected to each other by accident. Risk of short circuit!
Check if you have assigned the connecting cables on the adapter PCB properly to the connections of the decoder.

⚠ Caution:
Confusing the connections can cause damages at the deocder and/or at the vehicle. For that reason you should be very attentive when assigning the connections.

3.4. Assignment for PluX adapters (NEM 658/RCN-122)

3.5. Assignment for 21MTC adapters (NEM 660/RCN-121)

In order to avoid damage due to a connection of the decoder with reversed polarity, you sould remove the index pin (pin 11) at the 22-pole plug connector. You can withdraw the pin with small pliers.

4. Checklist for troubleshooting and error correction

⚠ Warning: If you notice a strong heat development, immediately disconnect the connection to the supply voltage. Fire hazard!

Possible causes:

The connecting cables on the PCB are badly assigned to the connections of the decoder or the vehicle. à Perform a visual check and remedy defects. Damage on the decoder or the vehicle cannot be excluded.
The plug connector or the socket have been inserted the wrong way. à Check the connections and remove the index pin to avoid mistakes like these.

You cannot switch function outputs of the decoder.
Possible causes: n The connecting cables have not been soldered properly. à Check the soldering joints.
The cables on the PCB have not been assigned properly to the decoder / the connections in
o the vehicle. à Check the connections. r The plug connector or the socket have been inserted the wrong way. à Check the t connections and remove the index pin to avoid mistakes like these. k
