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 motor brushes or ancillary outputs
to pickup shoes, frame, or wheels may destroy the device!
Installation of the loco-decoder 75 400
Motor connections
Remove the old reverser and unsolder
all wire connections. Solder the brown
lead to the frame, the red one to the
pickup shoe, and the blue and green
ones to the brush connections of the
motor.
Important: RFI suppressors and
capacitors should be retained.
Installation of an extra function
Connect the gray and yellow leads to
the front and rear lamps. Their ground-
connection must be kept. Should the directional lighting come on wrong, change the green and
blue leads on the motor. Connect both outputs with each other if you wish them to work direction-
independently.
There are other devices possible that can be controlled by the ancillary outputs, e. g. a smoke
generator.
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.
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.
Safety first
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.
