My system is a NCE cab system, using a AIU and Accessory Decoder CDU Solenoid Drive SX 8-Way to control turnouts and control panel. A USB interface for computer connection and BD20’s were installed as current sensors to be used for train detection. I am very happy with the NCE system and found it generally plug and play once the correct address was used, especially for the AIU (cab address 4 needed to be used). Train Controller was very easy to set up all aspects of the NCE system but needed the different cab address to get the AIU to connect.
