-====== NMEA 2000 & MFD integration guide ======
+====== Marine Integration Guide ======
 ===== 1. Introduction =====
 ==== 1.1 Summary ====
-This document explains how to integrate a Victron system onto a marine MFD also known as a chart plotter. Compatible brands include Garmin, Raymarine, the Navico brands B&G, Simrad and Lowrance as well as Furuno.
-There are multiple options, and how to best integrate depends on the customer requirements, preferred MFD brand and model as well as used Victron components.
+This guide provides an overview of integrating Victron systems with marine networks. These features include:
-Make sure to closely read this full document to find the best method for your type of system.
+  * **MFD (Chart Plotter) Monitoring**: Compatible with Garmin, Raymarine, Furuno, and the Navico brands B&G, Simrad, and Lowrance.
+  * **Tank Level Monitoring**: Seamlessly integrate tank level data between the NMEA 2000 network, Victron GX devices and the VRM Portal.
+  * **NMEA2000-out feature**: Share tank data, as well as other data such as Battery, DC & AC system data from GX devices to the NMEA 2000 network.
+  * **GPS Integration**: GX devices can read GPS data (e.g., location, speed) from NMEA 2000 but do not output GPS data to the network.
+  * **Advanced features powered by Signal K**: Includes wireless AIS, anchor alarms, and automatic trip logging.

+This document serves as a high-level overview with links to relevant manuals for detailed setup instructions.
-==== 1.2 What is NMEA 2000? ====
-NMEA 2000 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.
+==== 1.2 MFD Integration ====
-NMEA 2000 is sometimes also refered to as N2K, for brevitiy.
+Integration with MFDs depends on customer requirements and equipment used. A GX device (e.g., Cerbo GX or Ekrano GX) is typically involved, with two main options:
-==== 1.3 What is the MFD HTML5 App? ====
+  - **NMEA 2000 Integration**: Connect the GX device directly to the NMEA 2000 network.
-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.
+  - **HTML5 App Integration**: Connect the GX device and MFD via Ethernet to enable Garmin OneHelm or Raymarine LightHouse Apps.
-==== 1.4 Other integration options ====
+**Comparison of Options:**
-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 [[ccgx:modbustcp_faq|]].
+  - **NMEA 2000**: Offers customizable data pages on the MFD but requires more configuration.
+  - **HTML5 App**: Plug-and-play with an auto-configured system overview but less customizable.
-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.

Click those links to go straight to all information, videos and manuals.
+==== 1.3 Tank monitoring ====
-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 [[https://www.victronenergy.com/media/pg/Cerbo_GX/en/marine-mfd-integration-by-nmea2000.html|NMEA 2000-out chapter in the Cerbo GX manual]].
+The Victron GX devices offer a user-friendly **Tank Level Page** to centralize and visualize data, as well as integration with MFDs and the NMEA 2000 network.
-Both the NMEA2000 and HTML5 App/Ethernet connections can be made and used at the same time.
+**Key Features:**
+  * Monitor tank levels on the GX device and VRM Portal.
+  * Access NMEA 2000 tank data or share GX tank data with NMEA 2000.
+  * Customize tank naming, shapes, and damping for accurate readings.
+  * Expand capabilities with the [[https://www.victronenergy.com/accessories/gx-tank-140|GX Tank 140]] module for voltage (0-10V) or current (4-20mA) inputs.
-Each has its advantages and disadvantages, and together they complement each other:
+**Visual Examples:**
-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.
+{{ :ve.can:nmea-2000:brief_page_tanks.png?direct |}}
-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.
+{{ :ve.can:nmea-2000:tank_grouping.png?direct |}}
-As mentioned above, a GX Device can also read tank level data from NMEA 2000. More information in the [[https://www.victronenergy.com/media/pg/Cerbo_GX/en/installation.html#UUID-9813aef4-8178-293b-12ef-0048b064271f|the Installation chapter of the GX manual]].

+  * **Reading data from NMEA 2000 Tank senders into the GX Device and VRM Portal:** The GX device can read tank level data from compatible sensors on the NMEA 2000 network. This information is then displayed on the GX interface, including the dedicated tank level page, and synced with the VRM Portal. For compatibility details, see [[https://www.victronenergy.com/media/pg/Cerbo_GX/en/connecting-supported-non-victron-products.html#UUID-9f759229-3e91-5a02-891c-2206c9625753|the 3rd party NMEA 2000 tank sender section in a GX manual]].
+  * **Transmitting GX tank levels to the NMEA 2000 network:** For vessels with advanced monitoring setups, the GX device can also send tank data back to the NMEA 2000 network, enabling MFDs and other connected devices to access and display the information. For further information, see the [[https://www.victronenergy.com/media/pg/Cerbo_GX/en/marine-mfd-integration-by-nmea-2000.html|MFD integration by NMEA 2000 chapter in the GX manual]]. Note that the manual includes specifics steps for Garmin, Raymarine, Furuno and Navico systems.
-==== 2.3 Tank monitoring integration ====
+==== 1.4 NMEA2000-out feature ====
-The GX devices can measure tank levels, and make the resulting data available on the NMEA2000 network. Also, they can read tank level data from the N2K network.
+Victron Energy GX devices feature an NMEA 2000-out function: when enabled, the GX device acts as a bridge: it makes the data of all connected Battery monitors, Inverter/chargers, as well as other products connected to the GX device, available on the NMEA 2000 network.
-Below sections explain the details of each integration type.
+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.
-=== Integration A) GX Device to MFD and NMEA2000 ===
-Some of Victron GX monitoring products feature built-in tank level inputs. For example the [[https://www.victronenergy.com/panel-systems-remote-monitoring/cerbo-gx|Cerbo GX]], which is the most common GX device, has four inputs that can take a resistive tank level sender.
+==== 1.5 Advanced features powered by Signal K ====
-Also, all GX devices can also have their number and types of tank level inputs expanded by adding one or multiple [[https://www.victronenergy.com/accessories/gx-tank-140|GX Tank 140]] modules. It has four inputs, of which each can be configured to measure either voltage (0-10V) or current (4-20mA).
+Signal K unlocks powerful features:
+  * **Wireless AIS & Navigation Data**: Share NMEA 2000 data via WiFi for apps like Navionics.
+  * **Anchor Alarm**: Reliable and easy-to-use alarm.
+  * **Automatic Logbook**: Track journeys effortlessly.
-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.

+  - [[https://svrenaissance.com/victron-cerbo-gx-on-steroids/|Victron Cerbo GX on steroids blog post]].
-The GX Device can transmit the resulting tank levels to the NMEA2000 network. See the [[https://www.victronenergy.com/media/pg/Cerbo_GX/en/marine-mfd-integration-by-nmea2000.html|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.
+==== 1.5 Modbus-TCP, mostly for SCADA systems ====
-=== Integration B) NMEA2000 to GX Device and VRM Portal ===
+Ideal for larger vessels, the GX built-in Modbus-TCP server enables SCADA system integration. For more details, see the [[https://www.victronenergy.com/live/ccgx:modbustcp_faq|Modbus-TCP FAQ]].
-The other way around is possible as well: the Victron system reading tank level data from NMEA2000.

-==== 3.2 NMEA 2000 instancing ====
+==== 3.2 NMEA 2000 instances ====
-NMEA 2000 Instances are used to identify multiple similar products connected on the same network.
+Instances are used in an NMEA 2000 network to identify multiple similar products connected to the same network.
-There are several types of instances, the most important ones being the **Device instance** as well as the **Data instances**.
+As an example, take a system with two battery monitors (one for the main battery bank, and another for the hydraulic-thruster bank) and also a Quattro inverter/charger. All three of those devices will send their battery voltage measurements out on the NMEA 2000 network. For the displays to show these values at the right place, they need to know which voltage belongs to what battery. That is what instances are for.
-More information about instances is in [[https://www.victronenergy.com/media/pg/Cerbo_GX/en/marine-mfd-integration-by-nmea2000.html#UUID-97031b2e-6b21-dd88-56ee-31c0aaca9183|the NMEA2000 chapter in the GX manual]].
+There are various types of instances, and for marine systems are two that matter: the Device instance and the Data instance. The Data instance goes by various different names, like Fluid instance, Battery instance and DC instance.
-=== What settings need to be made? For example instances? ===
+NMEA 2000 defines three different instances:
-That is a commonly asked question. The answer depends on the used brand of MFD:
+  * Data instances (Battery instance, Fluid instance, and similar)
+  * Device instance
+  * System instance
-For **Garmin, Furuno, Maretron and Navico (B&G, Lowrance, Simrad) systems**: none. No instances, also not data instances such as the DC Detailed instance, need to be changed. It all works out of the box, other than configuring what field to show where on the MFD.
+=== When is manual configuration of instances needed? ===
-For **Raymarine**, you might need to do some configuration: for systems with a SmartShunt and a SolarCharger, or multiple SmartShunts, or a Lynx Smart BMS, the data instances need to be configured to be unique. More information about that in the [[https://www.victronenergy.com/live/venus-os:mfd-raymarine|Victron & Raymarine document]], in the last chapter.
+  * For **Garmin, Furuno, Maretron and Navico (B&G, Lowrance, Simrad) systems**: no configuration needed. Required fields can be configured and selected on the MFD, usually by pressing and holding on a data field in the data bar until the selection pane comes up.
+  * For **Raymarine**, before selecting the data on the MFD, the Battery and DC Detailed instance typically needs to be set up to be unique. For details, see the [[https://www.victronenergy.com/media/pg/Cerbo_GX/en/marine-mfd-integration-by-app.html#UUID-906e773b-f29c-2b77-56a8-d9ade87cc418|GX manual, Raymarine section]].

+==== 3.5 Galvanic isolation ====
-==== 4.1 Raymarine & EmpirBus ====
+When connecting a GX to an NMEA 2000 network, it is recommend to do so using a galvanically isolated CAN-Bus port.
-Besides using NMEA 2000 and/or the Lighthouse App, integration onto Raymarine MFDs can also be done with an [[https://www.empirbus.com/#nxt-mcu|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.
+This is especially the case when your NMEA backbone and GX are powered from separate power sources or do not share a common ground. These are the two most popular models that feature such galvanically isolated port:
-In the [[https://www.empirbus.com/#empirbus-studio|EmpirBus Studio software]] you will find dedicated Victron building blocks than can be drawn onto the diagram.
