+NMEA 2000 Instances are used to identify multiple similar products connected on the same network.
-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]])
+There are several types of instances, the most important ones being the **Device instance** as well as the **Data instances**.
+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]].
-==== 3.3 Maretron ====
+=== What settings need to be made? For example instances? ===
-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]].
+That is a commonly asked question. The answer depends on the used brand of MFD:
-===== 4. NMEA2000 PGN overview =====
+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.
-===== 5. FAQ =====
+==== 3.3 Terminators and network layout ====
-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]].
+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:
-==== Q1: What about instances? Device instances, data instances? ====
+  * 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.
-See [[ve.can:changing_nmea2000_instances|]] for details on that.
+Or:
-==== Q2: What about terminators and network layout? ====
+  * 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.
-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:
+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 ====
-  * Use the NMEA 2000 cable as the backbone.
+The Victron VE.Can network accepts 9 to 70VDC.
-  * Run a separate drop cable separately to each Victron device. The drop cable will be one of these three products:
-    * [[https://www.victronenergy.com/accessories/ve-bus-to-nmea2000-interface|VE.Bus to NMEA 2000 interface]]
+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.
-    * [[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]]
+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.
-  * Only terminate the NMEA 2000 backbone, do not terminate on the VE.Can side.
+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.

+===== 5. FAQ =====
+=== Q1: Can/must both Ethernet and and N2K connection be made between Victron GX and MFD? ===
+Both can be made at the same time.
+Ethernet is needed to get the MFD App, as explained above.
+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, using both the HTML5 App integration as well as using NMEA 2000. For Raymarine specific details, see [[https://www.victronenergy.com/panel-systems-remote-monitoring/marine%20mfd%20gx%20integration%20-%20raymarine|the Raymarine integration page manual]].
