Viessmann Signals with Gantry, Multiplex 52292 - Z21 Connection Help
I purchased for train station Viessmann Signal gantry and two multiplex signals. Now I want to connect that to Z21. I managed to get the power set up and pressed the red address button which rotated the lights through a process. Now the red light is on, but I don’t know what address the 52292 assigned to the signals. The Viessmann instruction booklet naturally only tells one how to connect to the Viessmannn digital commander system. I found one discussion on the website, but that person got farther than I have.

Here are photos of gantry and 52292
Update to my earlier comment and photos. I managed to get the signals programmed, but they only recognize all green or red. The distant signal is either green or off, never yellow/orange. I tried changing the switches for the two settings, but only one of the settings governs. The other doesn’t. I can try to reset, but thought I would ask for advice.
Hello Chip
Looking at your connection box, I am a bit puzzled that I see only 4 wires for each of your signals. I use Viessman N-scale 4412 Entry and 4413 Departure signals. The Entry signal has 1 each of red, green and yellow lights and with the power connection (diode) 4 connections in total. The Departure signal (without Distant signal) has 2 red, 1 green, 1 yellow and two white lights. The red lights can be addressed separately, the white lights are connected in pairs. There are a total of 6 connections including power.
I don't know whether your Distant signal is paralleled with the Main signal, but each colour needs a separate connection. Since you have 4 colours, there would have to be at least 5 connections if all same-colour lights always light up together. Perhaps your power connection is made by the red and white heavy wires. I am not familiar with the Viessman Multiplexer as I made my own controller.
My signals came with series resistors for each light as LEDs must have a current limiting resistor in series wit the LED. I cannot see any in your picture, but they may be located elsewhere, or the Multiplexer has them internally. To find out whether the problem is with your Multiplexer or the signals would be to disconnect the signals and check each signal light separately. But you would have to make sure that each LED light has a series resistor of typically 1200 Ohms in series when powered with 12VDC. Polarity matters as well.
I don't know whether this is of any help to you, but it might lead you to the cause of your problem.
Good luck!

Hello again Chip
I was interested in how your multiplexer works and found that you are not alone with problems. There is an article describing your problem at this website: https://www.modelrailforum.com/threads/viessmann-52292-multiplexer-and-z21-app.55473/
Cheers,
Uli
Uli —- Thanks for your comments - I am looking at this now. I am not yet retired and so end up with gaps in my ability to work on the model railroad and for following these posts. I should have done so much earlier. I do thank you for your time and attention. I am posting separately that in another location that I successfully set up a genuine 2 steam engine Consist. Every once in a while I can figure things out for myself. I am turning now to your two comments. The Viessmann comes with very few instructions and the wiring from the Viessmann box to the signals is a closed set — the connector is built in so I cannot add or subtract wires.
Update later July 7 — Thinking about Uli’s first comment above, I tried connecting the fixed power also to the top section of the multiplexer, but that made no change. I note that the Z21 for multiaspect signal set me as having two devices — in the case of the second signal devices 93 and 94. #93 seems to work just fine if 1 rather than zero is selected the main signal is red. If zero is selected the item is all green- both distant and forward signal. No matter what selections I make for #94, there is no impact on the signal. So somehow that is not getting a function signal.
Chip, I think you’re giving me too much credit for solving other Forum members' problems in your other post about successfully hitching two gorgeous steam locomotives in tandem.
I see that your Gantry Signals are still causing you frustration. As I am not using the Z21 Multiplexer and therefore don’t know how it works, the only thing I could suggest, but am sure that you have tried, is to switch the signals to see whether you get the same result. That would at least tell you that there is no defect with one of the signals.
From the two pictures you have posted (in your 2 separate posts) I surmise that you have quite a large setup. Perhaps you could post some overview pictures for us sometime. You are one of the very few contributors to the Forum nowadays. It has gone pretty dead after the recent long shutdown due to database migration. I am beginning to feel a bit self-conscious seeing my name in the comments so often. Although retired unlike you, progress on my small N layout is glacial, mainly due to other hobbies and projects and I haven’t made any recent progress worthy of posting. Guilty as charged, I suppose.
I hope that someone else with multiplexer experience can help you sort out the gantry signal problem.
Uli
Uli — thanks I did switch the set-up to see if I get a different result with no luck.
And I will post some photos soon - maybe later today of the layout to date. I need a lot of time to do much more on it and am constantly waiting new shipments from Europe especially for the Catenary which is super difficult. I need to take a high end soldering class.
