Message

public class GridConnectMessage
extends AbstractMRMessage

Class for GridConnect messages for a CAN hardware adapter.

The GridConnect protocol encodes messages as an ASCII string of up to 24 characters of the form: :ShhhhNd0d1d2d3d4d5d6d7; The S indicates a standard CAN frame hhhh is the two byte header N or R indicates a normal or remote frame d0 - d7 are the (up to) 8 data bytes
