I can't seem to get it to work even in the example code.

Can anyone varify for me that it dose work, and if possible show me a picture of a working circuit? Sorry, I just don't understand how it's supposed to work,

Were you able to figure out how it works?

No, sorry, I was not yet able to figure it out. I will try again.

Here is an example of a simple option:
There are 2 devices, each with one combinator, the first is a simple comparison one, the second is an arithmetic one.
Each installed column can set an input or output for the combinator (configured in the column itself).
You can enter the device by clicking in its middle.
Well, then you can collect any amount of anything inside the room and set your logic for it.

That is, the device allows you to create an isolated environment (room), in which you can make a very large logical chain of different combinators (and not only), and at the output get a compact "combinator", instead of building up part of your base. That is, in essence, you can combine several combinators in this one device, as if it were one combinator with all the functions of all combinators.
