This document explains how to integrate a Victron system onto a Marine MFD, such as those from Garmin, Raymarine, the Navico brands B&G, Simrad and Lowrance as well as Furuno other brands.

There are multiple options, and how to best integrate depends on the customer requirements, MFD brand and model as well as used Victron components.

Make sure to closely read this full document to find the best method for your type of system.

NMEA2000 is a communications standard used for connecting marine sensors and display units within ships and boats.

Victron Energy is a member of the NMEA 2000 organisation, and we have several of our products certified by NMEA 2000.

NMEA 2000 is sometimes also refered to as N2K, for brevitiy.

The MFD HTML5 App is a simple to install and setup integration into all main marine MFD brands, including Raymarine, Garmin, Navico and Furuno. Truly plug-and-play: once the Victron GX Device and the MFD are connected via ethernet, a Victron logo will appear in the App menu of the MFD. Behind that button, there is a page to monitor and control the Victron Energy system. The information on screen automatically adapts to the installed Victron system.

This document only covers integration via NMEA2000 as well as the MFD HTML5 App. There are two other alternatives, commonly used to integrate Victron equipment in a Marine applications.

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 GX Modbus-TCP Manual.

The other alternative is SignalK. More information about that in the Venus OS Large manual. Do take note of the contents of the Support chapter.

For most installations and integrations, it will be best to use one of our GX Products. It acts as a hub, collecting information from connected equipment, such as Inverters, Battery Monitors and Chargers; and then making them available to the MFD.

The GX devices offer both above introduced integration options: NMEA2000 as well as the Victron HTML5 App.

The HTML5 integration is available for Raymarine, Garmin, Furuno and Navico brands: B&G, Lowrance and Simrad. Click those links to go straight to all information, videos and manuals.

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, more information in the NMEA 2000-out chapter in the Cerbo GX manual.

Both the NMEA2000 and HTML5 App/Ethernet connections can be made and used at the same time.

Each has its advantages and disadvantages, and together they complement each other:

The MFD HTML5 App is the simpler one to setup as its plug and play. 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.

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 the Installation chapter of the GX manual.

Some of our products feature a VE.Can port; which can be directly connected to the NMEA 2000 network. No electronic converter is necessary. The conversion cable required is the VE.Can to NMEA2000 cable.

These products include our Skylla-i battery chargers, Lynx Shunt VE.Can battery monitor as well as the Skylla IP65 battery charger series.

The GX devices can measure tank levels, and make the resulting data available on the NMEA2000 network.

Also, they can read tank leven data from the network, when there are other tank senders connected. It will be shows it on the Victron screens as well as transmitted to the VRM Portal for remote monitoring.

Below sections explain the details of each integration type.

Some of Victron GX monitoring products feature built-in tank level inputs. For example the Cerbo GX, which is the most common GX device, has four inputs that can take a resistive tank level sender.

Also, all GX devices can also have their number and types of tank level inputs expanded by adding one or multiple GX Tank 140 modules. It has four inputs, of which each can be configured to measure either voltage (0-10V) or current (4-20mA).

All tank level inputs feature customisable naming, setting a type (fresh water, fuel, black water and more), configurable filtering and damping settings as well as setting up a custom tank shape for non-square tanks.

The GX Device can transmit the resulting tank levels to the NMEA2000 network. See the NMEA2000-out chapter in the GX manual for information on how to set that up. Note that the MFD HTML5 App does not include showing tank levels.

The other way around is possible as well: the Victron system reading tank level data from NMEA2000.

The tank data will be shown in the GX device user interface as well as on the VRM Portal. Screenshots below.

Compatible tank senders are listed in the GX manual, installation chapter.

TODO ADD SCREENSHOTS

• VE.Bus to NMEA 2000 interface
• VE.Direct to NMEA 2000 interface, for BMV Battery Monitors (only).

Note that the use of both those interfaces is deprecated. Use a GX device instead.

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.

• Skylla-i 24V Battery Chargers
• Skylla IP44 Battery Chargers
• Lynx Shunt Battery Monitors
• Lynx Ion + Shunt all models
• SmartSolar MPPT Solar Chargers with VE.Can communications port

Besides using NMEA 2000 and/or the Lighthouse App, integration onto Raymarine MFDs can also be done with an Empirbus NXT MCU . Though both are 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.

Note that there are many more generic frequently asked questions answered in the Data communication white paper.

See Changing NMEA2000 instances for details on that.

A N2K CAN bus network needs to be laid out as in a backbone configuration, using drop cables to connect to each device. Also, there should be only two terminators in the network. Therefore:

• Use the NMEA 2000 cable as the backbone.
• Run a separate drop cable separately to each Victron device. The drop cable will be one of these three products:
  • VE.Bus to NMEA 2000 interface
  • VE.Direct to NMEA 2000 interface
  • VE.Can to NMEA 2000 cable
• Only terminate the NMEA 2000 backbone, do not terminate on the VE.Can side.

See the NMEA 2000 chapter in the CCGX manual for details.
