The Deling bus-based decoder converts different communication protocols between devices such as elevator cabins, control rooms, and management centers, enabling them to communicate over a unified bus system. For example, it converts the intercom equipment signal protocol inside the cabin into a protocol suitable for four-core bus transmission, ensuring accurate signal transmission on the bus. The NKT12(1-1)C is used for main units with up to 49 floors, while the NKT12(1-1)D is used for elevators with more than 49 floors.
