The other part of the electronics is a decoder (MM2) with a relay for current control in stop sections (rail and overhead wire) and a decoder output for the signal head. This version is the early release from 2003 till 2013. There are no CV programming but only a metal clip with the box for programming. So if I remember correctly (I had a failing signal of this type very long time ago (2003) so I opened it) there are SMC (Surface Mounted Circuits) mounted with tiny LEDs, resistors, an IC all in a few mm² (may be 10 x 3 mm). So if you are experienced with SMCs (Large illuminated magnifying glass, special soldering gear with hot air pump, special soldering paste and having SMC components - resistors) and willing to risk destroying your signal you may try changing SMC resistors for smaller values (higher current). Otherwise I recommend you don't. The signal head is assembled by high precision robots so it will be very tricky. Jean

In the new generation signal 76496 (MMS, DCC, MFX), there is one CV (40) to adjust the luminosity but factory setting are at maximum luminosity See here page 12 to see all CVs https://static.maerklin....46ee63ffbf1591098946.pdf Cheers Jean

I guess you need to program a 76xxx sign model? assuming this is the case, attempt to get an english form of the CS1 manuel, I think the programming system is something very similar (I figured out how to program a square sign, which turns out great). remember that you can possibly program a sign when it is as yet bundled (or if not, you need to utilize the little metallic jumper). how to order pcb online Edited by user 02 April 2021 00:14:27(UTC) \| Reason: Not specified

When still in their package, if you power up and send a command (like for a switch) then the signal will take note of the used address and as soon as you power off and extract the signal it is ready and programmed. The new generation of signals (not hobby, not start-up) are multi protocols (MM2, DCC, MFX). When you connect them to your CS1, they will register by themselves using MFX. Otherwise you may enter the address using the set of switches for DCC and MM2 Cheers Jean
