Modifications of the 66032

The 66032 DELTA decoder has been offered by Märklin since 2002. This decoder can be modified to make the lights remotely controllable (default: permanently on) via the "function" button, and to make the output for telex or other purposes remotely controllable (default: via direction reversals) via the "f1" button. The lights function modification has first been published by Jürgen Schad, the f1 function modification has first been publically mentioned by Lutz Hemmerich to the MBG discussion group. Here is a collection of their findings. Pictures are courtesy of Lutz Hemmerich.

lights via "function"

To make the headlights controllable via the "function" button of a control unit, you need to close the solder bridges on the back (unpopulated) side of the decoder. The picture shows the decoder in its original (unmodified) state. The solder bridges to be closed are marked with "Brücke schliessen".

output via "f1"

To make the telex output (white cable) controllable via the "f1" button of a control unit, you need to close one and open the other of the two solder bridges at the edge near the middle "AS3" transistor on the top (populated) side of the decoder. The picture shows the decoder in its original (unmodified) state. The solder bridge to be closed is marked with "Brücke schliessen". The solder bridge to be opened is marked with "Brücke öffnen".

Further comments

• The negative pole of the internally rectified DC voltage (typically with a violet cable) is available from the solder pad between the blue cable pad and the component marked "10 6V". Now a sound module can be connected to the orange and violet cables, and a sound effect be triggered by the f1 function output.
