Please note that the correct address must be set on the decoder for the uncoupler track. 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.
Four consecutive addresses can accordingly always be accessed on a k83 decoder.
During the configuration process for the uncoupler track 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 on the k83 decoder) and then transfer the settings to the decoder for the uncoupler track.
