Programming of Uhlenbrock Decoders by Intellibox
The most comfortable way to program a decoder is offerd by the Intellibox. A menu-driven
programming mode in plain english is provided. Programming is carried out by selecting the menu
for non-compensated decoders (750/770, 75100 or 754xx).
You find exact instructions in the Intellibox handbook.
Programming of Uhenbrock Decoders by LOKTOOL
This computer routine is used to program Uhlenbrock decoders by applying a Märklin central unit
in connection with a Märklin interface. See reverse for a brief description..
A short circuit from decoder parts to input or chassis
or at the motor/lamp outputs may destroy the device!
Fitting the loco-decoder 75 420
Connection of the unit
Remove the shorting plug or the old reverser of
the loco and insert the interface plug into the
socket.
Should the headlights be lit in the wrong direction,
the plug must be turned by 180°.
Caution
Most of the models suitable for ac-operation
are already equipped with 19V-lamps that are
also compatible with digital operation.
Should you find lamps for a lower voltage, replace them before changing over to digital
operation.
Installation of an extra function
There are other devices possible that can be controlled by the ancillary outputs, e. g. a smoke
generator.
Connect both outputs with each other if you wish them to work direction-independently.
Fixing the unit in the model
Use the supplied adhesive pad for fixing where there is room for the decoder. The pad keeps
the unit insulated and fixed in its position.
In case the loco has a high current consumption, we recommend to fasten it directly to a metal
chassis frame with hot glue. All common brands are suitable for this.
Check for proper wiring after installation with a wiring checker or an ohmmmeter. Make sure that
the shell will not touch the unit and that no wires can be caught when shell is installed.
