-There are two ways to connect a GX Device to a MFD:+The GX devices offer both above introduced integration optionsNMEA2000 as well as the Victron HTML5 App.
  
-- the (simpler) plug and play like method uses an Ethernet connection, which enables the MFD HTML5 App. 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]], as well as the [[https://www.victronenergy.com/panel-systems-remote-monitoring/marine%20mfd%20gx%20integration|Navico brands B&G, Lowrance and Simrad]].

-Both connections can be made and used at the same timeand each has its advantages and disadvantages:+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-outmore 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 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.+Both the NMEA2000 and HTML5 App/Ethernet connections can be made and used at the same time.

-Since the Victron VE.Can communication protocol is based on N2K, the following products can all be connected directly to a N2K networkThe only thing necessary is a plug converter: the [[https://www.victronenergy.com/cables/ve-can-to-nmea2000-cable|VE.Can to NMEA 2000 cable]].+N2K CAN-bus network needs to be laid out as in a backbone configurationusing drop cables to connect to each deviceAlso, there should be only two terminators in the network. Therefore:
  
-  * Skylla-i 24V Battery Chargers +  * Use the NMEA 2000 cable as the backbone. 
-  * Skylla IP44 Battery Chargers +  * Run a separate drop cable separately to each Victron device [[https://nocache.victronenergy.com/accessories/ve-can-to-nmea2000-micro-c-male|VE.Can to NMEA 2000 cable]] 
-  * Lynx Shunt Battery Monitors +  * Only terminate the NMEA 2000 backbone, do not terminate on the VE.Can side.
-  * Lynx Ion + Shunt all models +
-  * SmartSolar MPPT Solar Chargers with VE.Can communications port +

 +Or:
  
 +  * 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.
  
-==== 3.Raymarine & EmpirBus ====+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.

- +
-See [[ve.can:changing_nmea2000_instances|]] for details on that. +
- +
-==== Q2: What about 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. +
-  * Run a separate drop cable separately to each Victron device. The drop cable will be one of these three products: +

-    * [[https://nocache.victronenergy.com/accessories/ve-can-to-nmea2000-micro-c-male|VE.Can to NMEA 2000 cable]] +
-  * Only terminate the NMEA 2000 backbone, do not terminate on the VE.Can side.+
  
-==== 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]].
