14. Marine MFD integration by NMEA 2000

14.1. NMEA 2000 Introduction

Victron Energy GX devices feature an NMEA 2000-out function: when enabled, the GX device acts as a bridge: it makes all
Battery monitors, Inverter/chargers and other products connected to the GX device available on the NMEA 2000 network.
Using that feature, and having the GX device connected a NMEA 2000 network, Marine MFDs can read this data and visualise it
to the user. Often in a highly configurable manner.

Comparison to the App integration
Compared to MFD integration using the App, as explained in the previous chapter, integration via N2K offers a more customisable
configuration. The downside of integration via N2K is that there is more work in making such configuration, as well as making
sure all PGNs and fields therein are supported and compatible between the Victron system and the MFD.

Yes, that is a lot of reading, but that is basically inherent to NMEA 2000: for example, some of those MFDs support displaying AC
data received over the NMEA 2000 wiring, others do not. Some require changing Data instances, others do not, and so forth.
14.2. Supported Devices / PGNs
NMEA 2000 defines several messages.
• Messages are identified by their parameter group number (PGN).
• A textual description of the message is publicly available on the NMEA 2000 website (http://www.nmea.org/).
• Detailed specification of the protocol and message definition or part thereof can be ordered online on the NMEA 2000 website.
• NMEA 2000 is based on and compatible with SAE J1939. All AC information messages are in the AC status message format
as defined in J1939-75. The specification of these messages can be bought on the SAE website (http://www.sae.org/).
• For a detailed list of PGNs, please refer to our
Inverter/chargers
• All inverter/chargers that connect using a VE.Bus port are supported. This includes Multis, Quattros, MultiPlus-IIs, and other
(similar) Victron inverter/chargers.
• Data is transmitted out; and its possible to set shore current as well as switch the inverter/charger on and off as well as activate
the Inverter only and Charger only modes.
The interface has two functions:
