1. Getting started
How to use this manual
This manual gives step-by-step instructions for safe and correct
connecting and operation of the decoder. 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 decoder on to another person, please pass on the manual
with it.
Intended use
The Multi-Decoder MD-2 is designed to be operated according to the
instructions in this manual in digital model railway layouts. Any other
use is inappropriate and invalidates any guarantees.
The Multi-Decoder MD-2 should not be mounted by children under the
age of 14.
Reading, understanding and following the instructions in this manual
are mandatory for the user.
Checking the package contents
Please make sure that your package contains:
one Multi-Decoder MD-2 (ready-built module) or
one Multi-Decoder MD-2 in a housing (complete unit)
a D (containing the manual and further information)

Required materials
In order to connect the decoder, you need wire. Recommended
diameters:
> 0,05 mm² for the connections to LEDs, push buttons and
switches;
> 0,25 mm² for all other connections.
When using motor-run turnouts, you need an additional adapter AMW-2
for each turnout (item-no. 72-00086).
2. Safety instructions
Caution:
The decoder 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.
Mechanical hazards
ut wires can have sharp ends and can cause serious injuries. Watch
out for sharp edges when you pick up the P B.
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
Page 5
tams elektronik
English Multi-Decoder MD-2
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.
onnect 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.
Other dangers
hildren can cause any of the accidents mentioned above because they
are inattentive and not responsible enough. hildren under the age of
14 should not be allowed to mount this module.
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. Operation overview
The MD-2.BiDiB is a stationary decoder used to control a maximum of 8
servos. In addition, coil driven turnouts or semaphore signals,
decouplers or other accessories or push-buttons for manual activation
of the servos can be connected.
Operating mode 1:
8-fold servo decoder
+ turnout- and/or
switching decoder
onnecting area 1
("pin headers")
8 servos*1
(8-fold servo decoder)
onnecting area 2
("terminal strips")
4 solenoid accessories*2
(4-fold turnout decoder)
or 8 other accessories*3
(8-fold switching decoder)
or combination of turnouts and other
accessories
* see page 8

Operating mode :
8-fold servo decoder
with push-buttons
for manual activation
onnecting area 1
("pin headers")
8 servos*1
(8-fold servo decoder)
onnecting area 2
("terminal strips")
8 push-buttons for toggling between the
servos´ two end positions (as well
suitable for purely analogue operation)
*1 Servos: to control for example turnouts, semaphore signals or
(railroad crossing) gates.
*2 Solenoid accessories: accessories switched by short switching
impulses, for example coil driven turnouts (with or without limit stop),
coil driven semaphore signals, decouplers. Hint: In order to control
motor-run turnouts, you need an additional adapter AMW-2.
*3 Other accessories: for example light signals (to switch over between
the signals) or other lights (to switch them on and off).
The voltage supply for the connected accessories is provided by the
Multi-Decoder MD-2.

Motion sequences
You can set separately for each of the 8 servos:
Starting and end position
Rotational speed
Simple linear motion curve or linear motion curve with teetering
when reaching the end position (to be adjusted separately for the
two directions of motion)
Simple linear motion curve with constant
velocity.
It is not possible to break the motion sequence
before the end position has been reached.
When reaching an end position the motion
sequence is stopped automatically.
Linear motion with teetering at the end
positions (typical motion sequence of
semaphore signals and railroad crossing gates).
The teetering motion has to be set separately
for each direction of motion.
Driving the decoder via accessory decoder commands
Turnouts, servos or other accessories are operated via accessory
decoder commands in D or Motorola format, sent from the controla
unit to the accessory decoder´s addresses:
operating mode 1: 12 addresses
operating mode 2: 8 addresses
The decoder automatically recognizes the commands´data format. It is
possible to switch the outputs via mixed D and Motorola commands
as well as to operate one output alternately in D and Motorola
format.

English Multi-Decoder MD-2
Use in analogue mode
When operating mode 2 is set (for connection of buttons in connection
area 2) the servos can be controlled either by turnout commands or by
the connected buttons. This means that the MD-2 can also be used in
pure analogue operation.
Programming
Using a D central unit, the decoder address and the decoder´s
features can be defined by programming the configuration variables
( V). It is also possible to set the address by using a push-button
switch.
When using a Motorola central unit the (accessory) decoder address
has to be set with a push-button switch. hanging the other decoder´s
features is not possible in layouts run in Motorola format only.
Feedback via RailCom (according to R N-217)
The Multi-Decoder MD-2 is Rail om compatible, i.e. the decoder is able
to pass the Rail om messages via the rails to special Rail om detectors.
After a switching or setting command to its address the decoder sends:
status message, e.g. "turnout is set right", "turnout has been
switched" or "turnout still has to be switched" and / or
time message, e.g. "another 2 seconds are required to carry out the
switching or setting command" and/or
error message, e.g. "turnout cannot be switched"
and, by this, confirms the recepton of the command.
