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 t e 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:
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 22-
pole 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 MTC interfaces
Standard NEM 58 / RCN-122 NEM 0 / RCN-121
Number of pins 12, 1 or 22 22
Plug connector on the decoder in the vehicle
Socket in the vehicle on the decoder
PluX interfaces for different gauges
PluX-interfaces have 12, 1 or 22 connector pins and that way are suitable to be mounted in
vehicles of different gauges (or with varying space requirements). The assignment of the
different versions allows to insert a plug connector with 12 or 1 connector pins into a socket
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
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
removed.
2.2. Mounting versions
The (PluX- or MTC-) vehicle decoder can be inserted as well from the top as from the bottom
into the adapter PCB. The assignment of the PCB´s contacts depends on the direction of
inserting the decoder.

3. Assembling the kit
3.1. Safety instructions
Mec anical azards
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.
T ermal 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.
Ot er 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 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
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.

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 58 or NEM 0 in
order to avoid mistakes when connecting the adapter PCB.
Perform a visual c eck!
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.
