components (also when the locomotive is running!).
5 All of the remaining wires in the locomotive should
be positioned and mounted in an orderly manner.
6 Where appropriate mount the speaker in the loco-
motive and connect it to the decoder.
7 Plug the decoder into the circuit board.
8 Put the locomotive into operation for a test run. Note
the direction of travel. Correct recognized mistakes.
9 Program and adjust the decoder according to your
wishes.
10 Assemble the locomotive again.
When a decoder is installed in the locomotive, the
mode of operation switch no longer has a function.

Calibration Run
1 The motor type must be selected before doing the
calibration (see CV 52).
2 The automatic calibration of the locomotive must be
done on a suitable oval of track without obstacles
(signals, grades, etc.). The calibration run cannot
be done on a roller test stand. The locomotive is
accelerated during the procedure to the maximum
speed and it can thereby tip over from the track on
small radius curves.
3 For automatic calibration of the locomotive:
mfx – Go into the locomotive configuration on the
Central Station 2 or Central Station 3. Enter the value
77 at the first spot in the field „Firmware Version".
DCC/MM – Program the CV 7 to the value 77.
4 Start the calibration run by setting the speed control
knob to any speed. The locomotive will then start
slowly and accelerate to the highest speed and
it will then stop after a short while. After that, the
locomotive will attempt to start up. When the loco-
motive is finally standing at a stop, the calibration
is completed. You must not interfere at any point
during the entire procedure.
5 The calibration can be terminated with Stop, turning
the speed control knob (-> 0), or changing the direc-
tion of travel. The calibration run can be repeated
several times.
6 If the result is not satisfactory, the calibration can
be repeated with another motor type.
7 After the calibration run, the individual control para-
meters can be adjusted with the settings on the CVs.
Voltage Buffer
The decoder has a buffer that allows you to keep sound
operating in short areas of track without voltage.
The 55429 power storage device can be added to the
decoder in order to reach support functions that go
beyond the decoder. The 55029 decoder takes on the
control of this storage device.

Analog Operation
Locomotives with this decoder can be operated in
analog (AC / DC). The mode of operation is recognized
automatically. Those functions are active, which were
previously activate in digital operation for „Alternative
Track Formats" (see DCC, „Adjustable CVs").
Digital Operation
The digital protocol with the most possibilities is the
highest order digital protocol. The sequence of digital
protocols in descending order is:
Priority 1: mfx
Priority 2: DCC
Priority 3: MM
If two or more digital protocols are recognized in the
track, the decoder automatically takes on the highest
value digital protocol.For example, if mfx & MM are
recognized, the mfx digital protocol is taken on by the
decoder. Individual protocols can be deactivated with
Parameter CV 50.
Notes on digital operation
• The operating instructions for your central unit will
give you exact procedures for setting the different
parameters.
• The setting done at the factory does not permit
operation with opposite polarity DC power in the
braking block. If you want this characteristic, you
must do without conventional DC power operation
(CV 29/Bit 2 = 0).
• Address set at the facto:
DCC:
03
MM/fx 78

Control by UID, no adress
mfx-Protokoll
Addresses
• No address is required; each decoder is given a
onetime, unique identifier (UID).
• The decoder automatically registers itself on a
Central Station or a Mobile Station with its UID.
Programmierung
• The characteristics can be programmed using
the graphic screen on the Central Station or also
partially with the Mobile Station.
• All of the Configuration Variables (CV) can be read
and programmed repeatedly.
• The programming can be done either on the main
track or the programming track.
• The default settings (factory settings) can be produ-
ced repeatedly.
