+==== 3.2 NMEA 2000 instancing ====
-===== 3. Varia =====
+NMEA 2000 Instances are used to identify multiple similar products connected on the same network.
+More information as well as how to configure them is explained in [[ve.can:changing_nmea2000_instances|]].
-==== 3.1 VE.Can products (Skylla-i, Skylla-IP44, Lynx Shunt, Lynx Ion+Shunt and more) ====
+==== 3.3 Terminators and network layout ====
-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]].
+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:
-  * 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
-{{ :ve.can:nmea-2000:schema_nmea2000-vecan_mppt-skylla_nov_2016.png?nolink&700 |}}
+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.
-==== 3.2 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.

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.

 ===== 5. FAQ =====
-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]].
+=== Q1: Can/must both Ethernet and and N2K connection be made between Victron GX and MFD? ===
-==== Q1: What about instances? Device instances, data instances? ====
+Both can be made at the same time.
-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]].
