Cs3 Massoth switch decoders

Hi all. First post for me so be kind !! I have cs3 and am trying to use massoth switch decoders for my points. If I connect the first one all work ok via I pad (last years model ) and cs3. My problem is if I connect a second 4 switch decoder to the cs3 and then use my I pad numbers 1-4 work the points 5-8 and no control over 1-4. My layout consists of an internal garage with switches 1-4 and outside would be 5-16 all via 4 switch decoders. Am I missing something ?
 
Hi TTNUT TTNUT and welcome.
It sounds like you have not configured the DCC address of the second and subsequent Massoth accessory decoders. The default addresses of the 4 ports is 1-4. The manual tells you how to change the addresses. Rather than repeat those here have a go yourself and come back if you get stuck.
 
Welcome to the forum Nutty!

I concur with the Marvellous Idle Chap.

You will need to program the addresses 5-8, 9-12 & 13-16 for your other three decoders. I'm not familiar with the CS3, so it's either read the manual or wait for someone else here who can help.

Your other option is to ask your friendly g Scale Retailer to do the necessary for you....
 
I don't have a CS3 so I can't advise on how to change CVs (sometimes called "programming"). The accessory decoder needs to be attached to "programming track" outputs of your command station. The CVs you need to change are as follows, using the example of configuring the accessory decoder for addresses 5-8:
CV32 from 1 -> 5
CV34 from 2 -> 6
CV36 from 3 -> 7
CV38 from 4 -> 8
See pages 11-13 of the Massoth accessory decoder manual 8156101 Switch Decoder 4K II – Massoth Elektronik GmbH
You may wish to use the "programming lock" feature which is also described in this section of the manual, but personally I have never found this necessary.
Hope this helps.
 
I'm working on it! I've got a Massoth programmer I've used in the past to program my 4K II. I was just able to change the addresses on a new 4K II using my CS3. It took some trial and error! I'm going to try setting it up again methodically from scratch and keeping track of the steps. I'll pass it on once I'm satisfied it works OK.

OK this may not be the most elegant but it works!

1. I recommend you disconnect from your layout before proceeding.
2. You can do this on the CS3's screen but I highly recommend you use VNC on your desktop or laptop. The curser and data entry is MUCH easier to control with a mouse and keyboard! Go here if you don't know how to use VNC: CS3 on computer.
3. connect a turnout motor, preferably a LGB EPL model, to the 4K II SW1 output as per the Massoth manual. The CS3 will not be able to read/program the decoder without doing this.
4. connect the 4K II's DCC in to the CS3 programming track out.
5. Hit the (un)STOP button to power up the programming track.
6. Go to the upper EDIT menu and using Add Article add a turnout.

7. You'll see something similar to this:

8. Change the turnout name to something you like and select DCC under Protocol. Note that you can change the name again later if you want. Edit added: don't worry about the DCC address yet.

9. Now hit OK. You will not be able to change the 4K II settings unless you have the item actually added to your list which OK does.

10. Go back to the edit menu and select "Edit Article List".

11. The turnout you just added will probably be highlighted in blue. If not, click on it.
D.png

12. click on the more arrow in the lower right corner and this screen will appear:
E.png

13. Click on the "Configuration" menu bar. The CS3 will read these default CVs. You'll see the "OK" appear in the right column as the CVs are read.
F.png

14. Now we're going to modify CVs 32, 34, 36, and 38, the DCC address registers of the 4K II. In the following example I chose the addresses 45-48. Double click on the CV column of the first line.
G.png
Enter "32"

15. Double click on the "Actual/Target" column of the first line.

H.png
Enter your first address. 45 in example. As soon as you hit the check mark the CS3 will change the CV. The "OK" will disappear and reappear once the value is written.

16. At this point I recommend you go to the next few lines and repeat 14 and 15 for CV34, CV36 and CV38. You can use the first line again but you will not be able to see what you've done.

I.png

17. Click on "Close" then change the turnout address to the first address you entered. 45 in the example.
J.png

18. At this point you can click on the turnout and should be able to trigger the turnout motor to test its operation. Click "OK" and you are done with the first turnout on you new 4K II.

19. The next three only require you to add the article, set the protocol to DCC and set the appropriate address.

You will need to repeat the above for you next 4K II.

Hope this helps!

Hi many thanks for your input regarding my cs3/ massoth issue. I had got as far as the configuration screen but couldn’t get to the cv lines. I have VNC viewer so will use that. Thanks again best wishes Baz

Hi Phil, thanks again for your advice and detailed information on inputting info on the 4K 11 decoder. I have been at this for a few days and have managed to input switch addresses 1 to 12 successfully with the exception of address 7. I checked the protocol was at DCC and the address was correct but still no joy . I have tested the points motor and it definitely works. In your experience is it best to completely remove addreses 5-8 and re-input the decoder from scratch ? Also the remainder addresses 13 - 20 won't work even though the protocol and addresses are correct. Is this the only method or are you trying other ways ? It seems you are one of the few who has completed this mission ! Many thanks for your help, kind regards, Baz Yorkshire Dales G scale Club Treasurer.
 
As I mentioned in post #5 I've got a Massoth programming module that I used in past. I only tried using the CS3 to program the 4K II because of your question and I wanted to try it out! I'll probably use the CS3 to program these switch modules in the future too now that I know how to do it. Programming 4K II modules as simple DCC switch decoders is actually easier with the CS3 than setting up and using the Massoth programming module.

As to you current difficulties, something may have corrupted some other CVs in the module(s) you are having trouble with. My best suggestion is that you delete on the CS3 all the devices associated with a problem module except the one you used for programming. Then using the programming track (don't forget to connect a switch motor to SW1) do a complete CV reset of the decoder. I'd reset everything beginning with the programming lock by sequentially writing 11, 16, 22, and 33 into CV8. See the 4K II manual. Then reboot the CS3.

After the decoder is reset try programming it again. I recommend disconnecting the CS3 from the layout when doing the programming to avoid any possibility of inadvertently changing the settings on other working modules with POM.
