3        Each Parameter Identifier (PID) has an identifier that is one or two bytes in length. The identifier is hexadecimal. The PID is followed by one or more data bytes. For example, the Relay Control PID is $F4 $4C. This PID is followed by two bytes of data (aa) that contain the status of the Generator Set Status Control relays. Data bits are given as binary digits unless the number is preceded by $. All data is sent with the most significant byte first.The following chart is a quick reference list of the Parameter Identifiers (PID).
