Please note that the correct address must be set on the signal decoder. This address consists of a particular group of settings for the decode switches on the k83 decoder and the use of a particular output on the k83 decoder.
There are accordingly 4 consecutive addresses that can always be accessed on a k83 decoder.
During the configuration process for the signal you can read the appropriate switch settings and the output to be used on the k83 decoder after you have selected the corresponding group of switches (8 switches for the k83 decoder) and then transfer the settings to the signal decoder.

If the signal setting does not correspond to the setting shown on the Central Station, then all you have to do is swap the two blue wires on the mechanism in question.
