J1939 (+), J1939 (-), and J1939 Shield are used as the J1939 communication link.
The message format uses the parameter group number as the label for a group of parameters.
Each of the parameters within the group can be expressed in ASCII, as scaled data, or as function
states consisting of one or more Bits. Alphanumeric data will be transmitted with the most
significant byte first. Other parameters consisting of two or more data bytes shall be transmitted
least significant byte first. The type of data is also identified for each parameter.
The following sections identify the parameters that are supported by DDEC.
