This is an old revision of the document!
The NMEA 2000 protocol is a plug-and-play communications standard used for connecting marine sensors and display units within ships and boats.
Many Victron Energy products can be integrated into an NMEA 2000 network. On this page, you will find an overview, as well as links to all the detailed information.
Victron Energy is a member of the NMEA 2000 organisation, and we have several of our products certified by NMEA 2000.
For brevity, this document will refer to NMEA 2000 as N2K.
Use the VE.Bus to NMEA 2000 interface to connect these devices to an N2K network.
Monitoring and controlling these products from both to a N2K network and a Color Control GX is possible. In that case, do not connect the Color Control GX to the VE.Bus network. Instead, connect it also to the N2K network. Use our VE.Can to NMEA2000 cable for that. The CCGX will read the MultiPlus or Quattro information from the via the N2K network.
Schematic diagram of combining a CCGX with NMEA 2000:
In above example, there needs to be a fuse in the VE.Can to NMEA2000 cable. Without it, the VE.Can port in the CCGX will be left without power and therefore does not work.
When the Multis/Quattros are connected to the CCGX via a VE.Bus to NMEA 2000 interface, there are some limitations compared to the normal direct connection. These limitations are:
Setting On/Off/Charger-only and a current limit from the CCGX does work. As does Remote VEConfigure.
Combining this with a CCGX on the same network is possible. Connect the CCGX to the N2K network as well, use our VE.Can to NMEA2000 cable for that. The CCGX will then read the BMV information via the N2K network.
Since the Victron VE.Can communication protocol is based on N2K, the following products can all be connected directly to a N2K network. The only thing necessary is a plug converter: the VE.Can to NMEA 2000 cable.
Using the NMEA 2000 protocol, Victron equipment can be integrated in many multi function displays. Such as the ones from Maretron, Raymarine, Garmin and many other brands
Note: working on a very large yacht featuring custom Scada and PLC networks? Consider integrating the Victron system with ModbusTCP instead of NMEA 2000.
Integration onto Raymarine MFDs is always done with an Empirbus NXT MCU . Though both connected to the same N2K network, the NXT MCU translates the N2K PGNs originating from the Victron equipment into Raymarine proprietary messages.
In the EmpirBus Studio software you will find dedicated Victron building blocks than can be drawn onto the diagram.
Next, use the EmpirBus Graphical tool to design the pages for on the Raymarine MFDs.
The EmpirBus system requires the data instance of battery status and dc detailed status to be unique when using multiple sources. (how to change data instances)
All data sent out by Victron devices can be picked up by the Maretron MFDs & software. See the Maretron N2KView® vessel monitoring and control software.
Refer to our Datacommunication whitepaper, page 8 and beyond, for a list of Victron products and their supported PGNs.
See Changing NMEA2000 instances for details on that.
No, they cannot be connected. Even though the VE.Direct to NMEA 2000 interface can be physically connected to these solar chargers, it will not work. Use our Solar Chargers with a VE.Can port instead.
Note that there are many more generic frequently asked questions answered in the Data communication white paper.
A N2K CAN bus network needs to be laid out as in backbone configuration, using drop cables to connect to each device. Also, there should be only two terminators in the network. Therefore:
Nothing. At the moment the CCGX only reads data from the NMEA 2000 network. The data it can read is:
See chapter 1.4.7 in the ccgx.
