Replaces DN163A2 Decoder. This new decoder has been designed for a better fit in current production Atlas models.
The following picture shows the location of all extra function pads on the DN163A0, DN163A1, DN163A3 and DN163A4. These decoders all share the same board layout. The length is different to fit the various models. Note: There is not a current production DN163A2. This decoder was retired after the manufacturer made changes to the chassis and the decoder no longer fit properly.
