Communication Interface CI – NMEA 2000®

Introduction to the topic

The »Communication Interface CI – NMEA 2000®« is a gateway for integrating fpCAN-equipped Fischer Panda generators with an NMEA 2000® network. The »Communication Interface CI – NMEA 2000®« converts fpCAN messages to NMEA 2000® messages so you can monitor your Fischer Panda Generator with NMEA 2000® displays. The »Communication Interface CI – NMEA 2000®« is certified by NMEA 2000® (https://www.nmea.org).

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.
