The PGN fields transmit all data available for the generator. So with some generators not all fields (SPNs) contain valid data, for example, for the oil pressure. |
Different multifunction displays show different subsets of the transmitted data. The »Communication Interface CI – NMEA 2000®« reports itself as an ac generator. Check your multifunction display concerning its supported PGNs. |
