Help programming an LGB sound module

Hello all,

I have an old LGB sound module, purchased around 14 years ago. The manual only contemplates programming using an LGB specific interface. Can anyone suggest how I program this using a Massoth Dimax 800z?

Many thanks in advance.
 
Hey Greg, Yes I have the manual and the CVs. I cant seem to access the programming capability. I have hooked it up to the track and tried POM and also to the programming track but no luck. Only input seem to be the track power inputs? Does it need to be unlocked?
 
It might be because it is installed in a loco with its own motor decoder on the same address, so there is CV conflict. If it is an LGB loco you could try turning the 3 or 4 position switch, usually in the cab, to 0 to turn off power to the motor decoder, then trying reading and writing the CVs to the 65000 module.
 
Seam to remember when we were putting LGB Sound Modules into Loccomotives that they were programmed separately before installation. Not done one for a long time now preferring Massoth Sound Decoders.
 
I bought this when they first came out, bit of a novelty at the time. I programmed it to run with my Spreewald and mounted it in a carriage that I hook into the multi-purpose socket on the back of that loco when I want to run it. It is programmed to that loco ID so it works with that loco. I programmed it with the old LGB universal DCC remote I used to have.

I have tried to program it by connecting directly to the main line (without the Spreewald on the track) and connected directly to the programming rails. I can't get a response out of it, read or write.

Given the time again I would get a Massoth sound decoder also.
 
You will only be able to change a limited amount of options on this. - But I guess you know that??

You should be able to read CV's on your programming track, you may able to right CV's, but get an error on the Navigator, as there will be no motor to give a 'kick' of feedback to tell the CS it has done it.

If there is an onboard motor decoder, or a power buffer, then these will both confuse the issue.
 
That's a point Phil, thank you. I have a buffer for the standing sounds, Ill try with that disconnected in the morning. There's no motor decoder, just the sound module in isolation I am working on. To this point I have been unable to read or (presumably) write. Presumably as I cannot read and there is no impact of my programming. I am trying to slow the chuff down to match the speed of the loco.
 
If you are working on the sound module in isolation then you may need some "load" to get the command station to recognise something is there. For example when you are programming a Massoth 8FL function decoder you need to connect a resistor to get feedback. If removing the power buffer has not effect you could try to install the sound module in a loco but turn power off to the motor decoder (switch position 0 as mentioned earlier) or install it in an analog loco.

Seam to remember that the unit gave a click as updates were being accepted?
 
Many thanks for your feedback Gents, I am sorry to inform you that I believe I have fried the output amp on the board..>:)

I went to lift the volume (for the first time in 14 years) and a brief stutter and smell of burning electronics later the thing went quiet. I I have lost a few db worth of hearing since the original setup and it wasn't loud enough. Subsequently remembered I put a 3 watt speaker in to replace the original 2w to get a fuller sound and left the volume low so as not to overdrive the amp (note to self; labeling helps).

Worth repairing? Probably not worth sending back to Germany (from Oz).

Looks like the Massoth XLS Spreewald sound module is my next upgrade.....
 
so, was it making sound up until then?

I've seen the part number, but never looked at a picture, is this what it looks like?

2w or 3w is just capacity, did you check the original speaker impedance before replacing? Sometimes they use funny impedances, I remember either ESU or Massoth used 100 ohm speakers at one point.

Give or take a blanking plug, that is the unit.. Massoth / LGB tend to use 8 ohm speakers..
 
Yes, that is the unit. Working fine until I fried it. It originally held an 8 ohm, 2 watt speaker. What I suspect has happened is that the 3 watt speaker has overloaded the internal amp when I raised the volume and fried something. It worked fine for many years on low volume (with the 3 watt speaker). It could really be anything given that it is now 14 years old however the coincidence of my volume activity is pretty compelling.
