Watch youtube video by "Modeltrainfun" He's good at it. That's how I did my #76496 signal with my CS3. He also shows how to with an MS2.

Hi Paul
Here is the user's manual for the Märklin signals of the 763XX series
https://static.maerklin....dcd4e838a31434542179.pdf

As explained in the manual
- choose an address
- select a duration of 1000 S
- connect the signal to the digital equipment (CS2, CS3, MS1, MS2) while the signal is still in its box (Programming jumper plugged-in)
- power on (no other data traffic, only the digital equipmt and the signal)
- WITHIN 30 seconds carry-on with explanation on page 7 and 8 of the above manual
- on the CS3 you may have to open the page to edit articles and then select the tab luminous signals or wing signals - whatever is the case)

Usually this is about programming the first digital address into your signal (hence the programming jumper) and then, depending on the signal type, to:
- reserve following addresses as needed
- make a good graphic representation of your signal and its various positions

I hope this helps

Cheers

Jean

I purchased only one signal of this type 76394.
I programmed it a few times no problem on a CS1 or CS2 (I don't remember) but then it soon gave-up (some diodes wouldn't light up), so it remained like this unused, waste of money.
So on your CS3 you must pick a signal of the same type (3 addresses in my case and probably yours)
On the CS3 you must pick a signal with 3 addresses (6 positions).
You must finish the programming before the 30 second deadline. Past this time, the signal goes into demo mode.
Cheers

Thanks again Jean,

Still no luck. I can see no reason why it does not advance beyond the first step. Programming appears normal - it offers me the first aspect, I select it, and then nothing. It then times out to demonstration mode. There's something very strange going on, perhaps related to CS3's latest software. I think I'll be returning these two signals if I have no joy this weekend. I've run out of ideas.

Paul

PS - I notice from your image above that my available choices are slightly different. The 76394 signal choice is the "scale" version only in my CS3.

Awesome advice, thank you so much Peter - that did the trick. Both signals now working perfectly having accepted programming with mFX and DCC and auto-start locomotives temporarily disabled on the CS3 (although programming was a little hit and miss until I converted the signals to the "scale" versions in the signal selector).

The boxes have the "v2" mark on them, and I'm hoping they work from here on in.

What a nightmare. Glad it's sorted thanks to your excellent advice.

Paul

Help. I am missing something. I can seemingly program the 2 functions with two key presses (4 functions total) of the 76394 V2, but they don't stay in memory of the signal. I read about a programming jumper in Jean's reply, but not sure what that is or what it looks like.
I tried with CS3 and with a older MM controller (Intellibox), which shows 2-light cycle and response that it is accepted (all leds on), then second cycle and all led response after 2nd key press (2 addresses). When I turn the unit back on, it returns to programming mode, so nothing is stored. After while it returns to showing all 4 settings in sequence (demo mode)
Suggestions?

Follow up: found answer on Dutch 3 rail forum. The decoder carton has wire that sets programming mode. Once programmed, remove carton+wire and voila. That was easy (if you know it).

I am unaware that Marklin have offered a fix since the last time you raised the issue
https://www.marklin-user...-upon-install#post638916

Here's what I learned.
The 763xx signals use 2 adresses for 4 light combinations. CS3 has that specific signal option already, so easy.
Rocrail does not have such a 4 setting signal option. You can select a regular 2 setting main signal, using two preferred light combinations (like double red for stop and green+white for go slow) by selecting their digital addresses (1 red and 2 green in my setup case).
Better yet, but more involved, is adding a theme (svg) to Rocrail that allows 4 light combinations for a signal. I got the relevant file from Hermann on the Rocrail support forum, so look there: https://forum.rocrail.ne...90&p=303926#p303926. Works great.
I have installed the nice signal on my M layout, though its small LEDs are less visible than the venerable 7188 bulbs it replaces (I switched because 7188 is underpowered by k83 decoder).
