K6400 dude

Good morning,
I do not understand how to determine the code k6400 kit.
Could give me an example of mounting plate jumpers on the P6400S to a key a key 1, 2, 3, 4?
Thank you very much.

Good evening,

look in the manual. The key combination 1,2,3,4 is on a picture in this manual.
The unused keys should be connected to ā€˜Nā€™.
