EX‑CommandStation to LGB 55025 switch decoder

[Railway42]

Hi, I am trying to configure my DCC EX‑CommandStation to work with the LGB 55025 switch decoder and wondered if anyone has attempted this as I am trying to understand where the following come from:

TURNOUT( id, addr, sub_addr [, "description"] )

Where do I find the ID, addr and sub_addr from?

I am not using the JMRI software that I have read other using elsewhere. I am using the Engine Driver and myAutomation.h to control my system.

Regards
Alan

Ok did one of these the other day. First on is number 1 so that points will be 1-4 as wired into the decoder. Next one is 5 and the points will be 5-8.

Then I get a little confused as the next one is 6 with points 9-11 then 7 continue with +1 for each decoder but plus the next 4 numbers for each point add infinitum (well there is a limit).

PLEASE CORRECT ME IF I AM WRONG ON THIS AND I WILL ALTER POST TO CORRECT INFORMATION

Basically Jon is correct.

These are 4 channel decoders so the first decoder will be switch numbers 1-4, then 5-8, then 9-12, 13-16, and so forth.

And you have to connect at least one channel to a load, such as a point motor to program.

I don't know the system you are using, but setting up with LGB protocol is quite simple....

Sorry gents, the question is not about how the LGB55025 works it is about how to connect it to the DCC-EX so that the command station recognises it. My question is has anybody carried this out and can give me any pointers please?
Thanks Alan

Not knowing DCC-EX, I can't give you specifics, and apologies if this is teaching you to 'suck eggs'. - I don't know your level of DCC knowledge.

There are 'motor decoders' and 'accessory decoders' and you address each slightly differently. - You could have a loco ans and a point /turnout with the same numerical address.

I would search through the DCC-EX instructions for 'point decoder' or 'accessory decoder' and see what you can find..

ID is a number that you give the point - what you would like to call it.

DCC++EX still uses the old style DCC accessory addressing, with a 'main' and 'sub' 'address. Basically, divide the DCC address of the point decoder by 4, the remainder is the sub address.
For example:
DCC 9 = 11/4 = 2.25, Addr 2 Sub 1.
DCC 11 = 11/4 = 2.75, Addr 2 Sub 3.
DCC 24 = 24/4 = 6 Add 6 Sub 0.


Very handy accessory address table:
