+ | NMEA 2000 is a communications standard used for connecting marine sensors and display units within ships and boats. | ||
- | A GX Device can be connected to a Marine MFD in two ways: the simple plug and play like method uses an Ethernet connection, which enables the MFD App. Available for [[https:// | + | Victron Energy is a member of the NMEA 2000 organisation, and we have several of our products certified by NMEA 2000. |

+ | This document only covers integration via NMEA2000 as well as the MFD HTML5 App. There are two other alternatives, | ||
- | === Direct connection | + | First of all Modbus-TCP. Typically used on larger vessels, Modbus-TCP is a protocol commonly used for (custom) designed SCADA systems. The Victron GX devices all support the Modbus-TCP protocol. More information in the [[ccgx: |
- | Some of our products feature a VE.Can port; and can thus be directly connected to the NMEA 2000 network. No electronic converter necessary; only a plug conversion cable, | + | The other alternative is SignalK. More information about that in the [[venus-os:large|Venus OS Large manual]]. Do take note of the contents of the Support chapter. |

- | Victron Energy is a member of the NMEA 2000 organisation, and we have several of our products certified | + | When connected to the onboard NMEA2000 network, the GX Device can read data from the network (tank level and GPS information). Also it can make data from Victron devices connected to the GX Device available on the NMEA2000 network. That latter feature is called NMEA2000-out, |

- | === Modbus-TCP Integration === | + | Each has its advantages and disadvantages, |

It presents an easy to use system overview without requiring any configuration. The system overview shown will automatically adapt to the type of Victron system installed. The (only) available configuration is defining the batteries as well as giving them names. |
- | ===== 2. Varia ===== | + | The NMEA 2000 integration is more complex, and allows more customisation on the MFD: the data will show up in the data-tree of the MFD, and most MFDs then allow the user to configure various pages and combinations of information. |
+ | As mentioned above, a GX Device can also read tank level data from NMEA 2000. More information in the [[https:// | ||

- | A N2K CAN bus network needs to be laid out as in a backbone configuration, | + | Note the other way around does not work. A GX Device which has a USB GPS installed does not emit GPS data out onto the NMEA2000 network as part of the NMEA2000-out function. |

- | ==== Q4: What PGNs does a GX Device transmit | + | Or: |
+ | |||
+ | * Have the N2K network on one side, with one terminator. On the other end, change to the Victron network, with also one (Victron) terminator at the end. | ||
+ | |||
+ | The first option is more aligned with the official N2K method. But, in case of multiple Victron products that need to be connected to the N2K network, will require more wire runs and definitively more NMEA2000 to VE.Can conversion cables. | ||
