Joined: 02/04/2013(UTC) Posts: 682		The Märklin Einheitsmesswagen 49960 is equipped with a MM1 decoder. My Märklin Mobile Station 2 can't send MM1 signals. Therefore, the Messwagen isn't full useable and I was thinking about possibilities to replace the decoder: Realization The MM1 decoder chip is placed on the mainboard of the Messwagen. Furthermore, it is not possible to replace the decoder chip with another version. But I found a very good description here: http://donaupeter.de/moba/Messwagen/messwagen.htm After I obtained this specific adapter board, I started to remove the unused parts, which is not so easy. Here, You see in the upper window this adaptor board on the mainboard and on the second picture the decoder behind the mainboard: Red-White headlights The fiber optics leed to all three haedlights and are powered by one bulb: To add red light to the lower headlights, only, I glued small red SMD-LEDs on the fiber optics edges: The bulb was replaced by a single warm-white SMD-LED, placed on the same place like the bulb. And this is how it looks now: Die Funktionen: Geschwindigkeitsmessung F1 = OFF F2 = OFF F3 = OFF F4 = OFF Messung in km/h (Vorbild) F1 = OFF F2 = OFF F3 = ON F4 = OFF Messung in m/s (Modell) Streckenmessung F1 = ON F2 = OFF F3 = OFF F4 = OFF Maßeinheit km (Vorbild) F1 = ON F2 = OFF F3 = ON F4 = OFF Maßeinheit m (Modell) Zeit-Messung F1 = OFF F2 = ON F3 = OFF F4 = OFF Maßeinheit Minuten (lang) F1 = OFF F2 = ON F3 = OFF F4 = OFF Maßeinheit Sekunden (kurz) Fahrzeit-Messung F1 = ON F2 = ON F3 = OFF F4 = OFF Maßeinheit Stunden (Betriebsdauer) F1 = ON F2 = ON F3 = ON F4 = OFF Maßeinheit Minuten (Fahrt) And here without the case but in english: Speed measure F1 = OFF F2 = OFF F3 = OFF F4 = OFF Measure in km/h (Vorbild) F1 = OFF F2 = OFF F3 = ON F4 = OFF Measure in m/s (Modell) Distance Measure F1 = ON F2 = OFF F3 = OFF F4 = OFF Measure in km (Vorbild) F1 = ON F2 = OFF F3 = ON F4 = OFF Measure in m (Modell) Time Measure F1 = OFF F2 = ON F3 = OFF F4 = OFF Measure in Minutes (long) F1 = OFF F2 = ON F3 = OFF F4 = OFF Measure in seconds (short) Driving time measure F1 = ON F2 = ON F3 = OFF F4 = OFF Measure in hours (total running time) F1 = ON F2 = ON F3 = ON F4 = OFF Measure in minutes (single run) F4 is to reset the measure values except the total running time.
