 +===== 3. NMEA2000 Details =====
  
 +==== 3.1 PGN Lists ====
  
 +Refer to our [[https://www.victronenergy.com/upload/documents/Whitepaper-Data-communication-with-Victron-Energy-products_EN.pdf|Datacommunication whitepaper]], page 8 and beyond, for a list of Victron products and their supported PGNs.
  
 +==== 3.2 NMEA 2000 instancing ====
  
-===== 3Varia =====+NMEA 2000 Instances are used to identify multiple similar products connected on the same network.
  
 +There are several types of instances, the most important ones being the **Device instance** as well as the **Data instances**.
  
-==== 3.1 VE.Can products (Skylla-i, Skylla-IP44, Lynx Shunt, Lynx Ion+Shunt and more) ====+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]].
  
-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]].+=== What settings need to be made? For example instances? ===
  
-  * Skylla-i 24V Battery Chargers +That is a commonly asked questionThe answer depends on the used brand of MFD
-  * Skylla IP44 Battery Chargers +
-  * Lynx Shunt Battery Monitors +
-  * Lynx Ion + Shunt all models +
-  * SmartSolar MPPT Solar Chargers with VE.Can communications port +
-{{ :ve.can:nmea-2000:schema_nmea2000-vecan_mppt-skylla_nov_2016.png?nolink&700 |}}+
  
 +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.
  
 +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.
  
-==== 3.2 Raymarine & EmpirBus ====+==== 3.3 Terminators and network layout ====
  
-Besides using NMEA 2000 and/or the Lighthouse Appintegration 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.+A N2K CAN-bus network needs to be laid out as in a backbone configuration, using drop cables to connect to each device. Alsothere should be only two terminators in the network. Therefore:
  
-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.+  * Use the NMEA 2000 cable as the backbone. 
 +  * 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]] 
 +  * Only terminate the NMEA 2000 backbone. Do not install a terminator in any of the VE.Can ports on the Victron products.
  
-Next, use the [[http://www.trigentic.com/#empirbus-graphic|EmpirBus Graphical tool]] to design the pages for on the Raymarine MFDs. +Or:
  
-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]])+  * Have the N2K network on one side, with one terminatorOn the other end, change to the Victron network, with also one (Victronterminator 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 ====
  
-==== 3.3 Maretron ====+The Victron VE.Can network accepts 9 to 70VDC.
  
-All data sent out by Victron devices can be picked up by the Maretron MFDs & softwareSee the [[http://www.maretron.com/products/N2KView.php|Maretron N2KView® vessel monitoring and control software]].+The NMEA-2000 network used to be 9 to 16VDC, which is, or will be, expanded to also include 24VWhich means that some NMEA-2000 devices are 9 to 16VDC, some are 9 to 30VDC, and some allow higher voltages.
  
-===== 4NMEA2000 PGN overview =====+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.
  
-Refer to our [[https://www.victronenergy.com/upload/documents/Whitepaper-Data-communication-with-Victron-Energy-products_EN.pdf|Datacommunication whitepaper]], page 8 and beyond, for a list of Victron products and their supported PGNs.+Therefore, it is important to **not** connect those power cables.
  
-===== 5FAQ =====+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.

-==== Q2: What about terminators and network layout? ====+==== 4.1 Raymarine & EmpirBus ====
  
-A N2K CAN bus network needs to be laid out as in a backbone configuration, using drop cables to connect to each device.

 +==== 4.2 Maretron ==== 
 + 
 +All data sent out by Victron devices on the N2K network 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]]. 
 + 
 +===== 5FAQ ===== 
 + 
 +=== Q1: Can/must both Ethernet and and N2K connection be made between Victron GX and MFD? === 
 + 
 +Both can be made at the same time.
  
-==== Q3: What PGNs does a GX Device transmit on N2K? ====+Ethernet is needed to get the MFD App, as explained above.
  
-See the [[https://www.victronenergy.com/live/ccgx:start#marine_mfd_integration_by_nmea2000|NMEA 2000 chapter in the CCGX manual]] for details.+And an N2K connection is needed to get data to show in other fields on the MFD.
  
-==== Q4: Can integration onto Raymarine displays also be done without Empirbus NXT? ====+See annotated screenshot above for which is what.
  
-Yes, see [[https://www.victronenergy.com/panel-systems-remote-monitoring/marine%20mfd%20gx%20integration%20-%20raymarine|the Raymarine integration page on our website]].
