 ===== 1. Introduction ===== ===== 1. Introduction =====
  
-This technical document explains how to integrate a Victron system onto a Marine MFD, such as those from Garmin, Raymarine Navico and other brands.+==== 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 ways to integrate, so make sure to closely read the complete introductory chapter to find the best method for your type of system.+There are multiple options, and how to best integrate depends on the customer requirementspreferred MFD brand and model as well as used Victron components.
  
-=== Systems with a GX Device ===+Make sure to closely read this full document to find the best method for your type of system.
  
-For most installations and integrations, it will be best to use one of our [[venus-os:start|GX Products]]It acts as a hub, collecting information from connected equipment, such as InvertersBattery Monitors and Chargers; and then making them available to the MFD. There are two ways to connect GX Device to an MFD:+{{:ve.can:nmea-2000:image_hml5_nmea2k_arrows.png?direct&500 |}}//Picture showing the two integration optionsNMEA2000 and HTML5 App. Click to see full size and see the difference between the two.// 
 +==== 1.2 What is NMEA 2000? ==== 
 +NMEA 2000 is communications standard used for connecting marine sensors and display units within ships and boats.
  
-the (simpler) plug and play like method uses an Ethernet connectionwhich enables the MFD App. Available for [[https://www.victronenergy.nl/panel-systems-remote-monitoring/marine%20mfd%20gx%20integration%20-%20raymarine|Raymarine]], [[https://www.victronenergy.nl/panel-systems-remote-monitoring/marine%20mfd%20gx%20integration%20-%20garmin|Garmin]], as well as the [[https://www.victronenergy.nl/panel-systems-remote-monitoring/marine%20mfd%20gx%20integration|Navico brands B&G, Lowrance and Simrad]]. Click those links to go straight to all information, videos and manuals. +Victron Energy is a member of the NMEA 2000 organisation, and we have several of our products certified by NMEA 2000.
-- in an the NMEA2000 network. See the [[https://www.victronenergy.com/live/ccgx:start#marine_mfd_integration_by_nmea_2000|NMEA 2000 chapter in the CCGX manual]] for details.+
  
-Both connections can be made and used at the same time, and each has its advantages and disadvantages. The MFD App is by far the simplest and plug and play-like method. It presents an easy to use system overview without requiring any configuration. The NMEA 2000 integration on the other hand, whilst being more complex, 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. This is not so with the MFD App, as the only available settings are to show or hide battery parameters (VoltageSOC, Current) as well as naming the batteries.+NMEA 2000 is sometimes also refered to as N2Kfor brevitiy.
  
-Note thatbesides making information available on NMEA 2000GX Device can also read tank level data from NMEA 2000. More information in [[https://www.victronenergy.com/live/ccgx:start#connecting_nmea-2000_tank_senders|the NMEA 2000 tank sender section in the CCGX Manual]].+==== 1.3 What is the MFD HTML5 App? ==== 
 +The MFD HTML5 App is a simple to install and setup integration into all main marine MFD brandsincluding RaymarineGarmin, 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 MFDBehind 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.
  
-=== Direct connection - products with a VE.Can port only ===+==== 1.4 Other integration 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.
  
-Some of our products feature VE.Can port; and can thus be directly connected to the NMEA 2000 networkNo electronic converter necessary; only a plug conversion cable, the [[https://nocache.victronenergy.com/accessories/ve-can-to-nmea2000-micro-c-male|VE.Can to NMEA2000 cable]].+First of all Modbus-TCP. Typically used on larger vessels, Modbus-TCP is protocol commonly used for (custom) designed SCADA systemsThe Victron GX devices all support the Modbus-TCP protocolMore information in the [[ccgx:modbustcp_faq|]].
  
-=== Using our converter interfaces (DEPRECATED!) ===+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.

-Note that the use of both those interfaces is deprecatedUse a GX Device instead.+==== 2.1 Systems with a GX Device ====
  
-=== What is NMEA 2000? ===+For most installations and integrations, it will be best to use one of our [[venus-os:start|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.
  
-NMEA 2000 is is a plug-and-play communications standard used for connecting marine sensors and display units within ships and boats.+The GX devices offer both above introduced integration options: NMEA2000 as well as the Victron HTML5 App.
  
-Victron Energy is a member of the NMEA 2000 organisation, and we have several of our products certified by NMEA 2000.+The HTML5 integration is available for  [[https://www.victronenergy.com/panel-systems-remote-monitoring/marine%20mfd%20gx%20integration%20-%20raymarine|Raymarine]][[https://www.victronenergy.com/panel-systems-remote-monitoring/marine%20mfd%20gx%20integration%20-%20garmin|Garmin]], [[https://www.victronenergy.com/panel-systems-remote-monitoring/furuno |Furuno]] and Navico brands: [[https://www.victronenergy.com/panel-systems-remote-monitoring/marine%20mfd%20gx%20integration|B&G, Lowrance and Simrad]]. Click those links to go straight to all information, videos and manuals.
  
-For brevitythis document will refer to NMEA 2000 as N2K.+When connected to the onboard NMEA2000 networkthe 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]].
  
-=== Modbus-TCP Integration ===+Both the NMEA2000 and HTML5 App/Ethernet connections can be made and used at the same time.
  
-For larger vesselsusing custom designed SCADA systems, the recommended protocol to use is ModbusTCP. See our [[ccgx:modbustcp_faq|]].+Each has its advantages and disadvantagesand together they complement each other:
  
-===== 2Varia =====+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.
  
-==== 2.1 VE.Can products (Skylla-i, Skylla-IP44, Lynx Shunt, Lynx Ion+Shunt and more) ====+As mentioned above, a GX Device can also read tank level data from NMEA 2000More 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]].
  
-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 [[https://www.victronenergy.com/cables/ve-can-to-nmea2000-cable|VE.Can to NMEA 2000 cable]].+==== 2.2 Products with a VE.Can port ====

 +==== 2.3 Tank monitoring integration ====
  
-==== 2.1 Raymarine & EmpirBus ====+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.
  
-Besides using NMEA 2000 and/or the Lighthouse App, integration onto Raymarine MFDs can also be done with an [[http://www.trigentic.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.+Below sections explain the details of each integration type.
  
-In the [[http://www.empirbus.com/clickOnce/EmpirBusStudio-Demo/|EmpirBus Studio software]] you will find dedicated Victron building blocks than can be drawn onto the diagram.+=== Integration A) GX Device to MFD and NMEA2000 ===
  
-Next, use the [[http://www.trigentic.com/#empirbus-graphic|EmpirBus Graphical tool]] to design the pages for on the Raymarine MFDs+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.
  
-The EmpirBus system requires the data instance of battery status and dc detailed status to be unique when using multiple sources. ([[ve.can:changing_nmea2000_instances#changing_a_data_instance|how to change data instances]])+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 (0-10Vor 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. 
  
-==== 2.2 Maretron ====+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.
  
-All data sent out by Victron devices can be picked up by the Maretron MFDs & software. See the [[http://www.maretron.com/products/N2KView.php|Maretron N2KView® vessel monitoring and control software]].+=== Integration B) NMEA2000 to GX Device and VRM Portal ===
  
-===== 3. PGN overview =====+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 [[https://www.victronenergy.com/media/pg/Cerbo_GX/en/installation.html#UUID-9813aef4-8178-293b-12ef-0048b064271f|GX manual, installation chapter]].

 +Our GX devices can read location, altitude, speed and course from the NMEA2000 network. For details, see the GX manual. 
 + 
 +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.

-===== 4FAQ =====+==== 3.2 NMEA 2000 instancing ====
  
-Note that there are many more generic frequently asked questions answered in the [[https://www.victronenergy.com/upload/documents/Whitepaper-Data-communication-with-Victron-Energy-products_EN.pdf|Data communication white paper]].+NMEA 2000 Instances are used to identify multiple similar products connected on the same network.
  
-==== Q1: What about instancesDevice instances, data instances? ====+There are several types of instances, the most important ones being the **Device instance** as well as the **Data instances**.
  
-See [[ve.can:changing_nmea2000_instances|]] for details on that.+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]].
  
-==== Q2: Can MPPT Solar Chargers with a VE.Direct port also be connected====+=== What settings need to be made? For example instances? ===
  
-No, they cannot be connectedEven though the [[https://www.victronenergy.com/accessories/ve-direct-to-nmea2000-interface|VE.Direct to NMEA 2000 interface]] can be physically connected to these solar chargers, it will not work. Use our [[https://www.victronenergy.com/solar-charge-controllers/smartsolar%20mppt%20ve.can|Solar Chargers with a VE.Can port]] instead.+That is a commonly asked questionThe answer depends on the used brand of MFD
  
-Similarlyalso a GX Device does not (yettransmit data from connected Solar Chargers on its NMEA2000-out port.+For **GarminFuruno, Maretron and Navico (B&G, Lowrance, Simradsystems**: 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.
  
-==== Q3What about terminators and network layout? ====+For **Raymarine**, you might need to do some configurationfor 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.
  
-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:+==== 3.3 Terminators and network layout ==== 
 + 
 +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.   * 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: +  * Run a separate drop cable separately to each Victron device [[https://www.victronenergy.com/accessories/ve-can-to-nmea2000-micro-c-male|VE.Can to NMEA 2000 cable]] 
-    * [[https://www.victronenergy.com/accessories/ve-bus-to-nmea2000-interface|VE.Bus to NMEA 2000 interface]] +  Only terminate the NMEA 2000 backbone. Do not install a terminator in any of the VE.Can ports on the Victron products. 
-    * [[https://www.victronenergy.com/accessories/ve-direct-to-nmea2000-interface|VE.Direct to NMEA 2000 interface]] + 
-    * [[https://nocache.victronenergy.com/accessories/ve-can-to-nmea2000-micro-c-male|VE.Can to NMEA 2000 cable]] +Or: 
-  * Only terminate the NMEA 2000 backbonedo not terminate on the VE.Can side.+ 
 +  * 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. 
 +==== 3.4 DC Voltage compatibility ==== 
 + 
 +The Victron VE.Can network accepts 9 to 70VDC. 
 + 
 +The NMEA-2000 network used to be 9 to 16VDC, which is, or will be, expanded to also include 24V. Which means that some NMEA-2000 devices are 9 to 16VDC, some are 9 to 30VDC, and some allow higher voltages. 
 + 
 +Also, the Victron VE.Can network will (in most cases) be powered with battery voltage. So for a 48V system, the voltage on the VE.Can network **exceeds** the NMEA-2000 accepted voltage levels. 
 + 
 +Therefore, it is important to **not** connect those power cables. 
 + 
 +The Victron cable used to connect both networks together, the [[https://www.victronenergy.com/accessories/ve-can-to-nmea2000-micro-c-male|VE.Can to NMEA 2000 cable]], has a removable fuse which is to be removed in case separation is necessary. A printed warning label is attached to the cable to warn about this.
