ABSTRACT:
A model train command protocol using front and back error bytes is disclosed. The front error byte is used to encode the data so that it is securely transmitted. The back error byte checks for proper transmission of the data itself. The entire encoded data sequence is known as a signature. The signature is sent by a user via a remote base through a communication link in a model train system. A receiver located within the model train system decodes the signature and executes the command.
