 To connect the [[https://www.victronenergy.com/live/venus-os:start|GX device]] to the internet as well, use Wi-Fi. If the Axiom MFD is connected to internet (using Wi-Fi), it will automatically share its connection with the GX device over ethernet.

 ===== 4. Configuration =====
 On the Victron GX Device, go to //Settings → Services//, and there enable both //MQTT on LAN (SSL)// and //MQTT on LAN (Plaintext)//.

+After connecting the Ethernet cable the GX device receives an IP number from the Axiom DHCP.
+If you start the Victron App on the Axiom and it shows "hardware devices not found", just restart the Axiom and see... it works!
 ===== 7. NMEA 2000 =====
-The MFD can also be connected to the Victron system using NMEA 2000, see the [[ve.can:nmea-2000:start|]].
+Besides connecting over ethernet, a Raymarine MFD can also be connected to the Victron system using NMEA 2000. If you’re new to NMEA2000 & Victron, start with reading the [[ve.can:nmea-2000:start|]].
-In order to properly display the NMEA 2000 data from Victron equipment, you need to change the data instances of the PGNs that are sent out. See here for how to do that: [[https://www.victronenergy.com/live/ve.can:changing_nmea2000_instances|Changing NMEA2000 Instances]], section Data instances.
+This chapter explains the specifics of NMEA2000 when connecting Victron to a Raymarine MFD.
+=== 7.1. Generic and supported PGNs ===
 To setup the data sources on the Raymarine, go to //Settings > Network > Sources > Advanced...//
-The following Victron related PGNs are supported:
+If you have more than 1 battery be sure to adjust the settings of the Axiom to the correct amount of battery(banks).
+The following Victron related PGNs are supported by Raymarine:
   * 127505 - Fluid level (tank levels)
   * 127506 - DC Detailed Status (State-of-charge, Time-to-go)
+  * 127507 - Charger status
   * 127508 - Battery Status (Battery Voltage, Battery Current)
+  * 127509 - Inverter status
-Below list of Victron related PGNs are not supported by the Raymarine, ie. in our tests we could not get such data to show on the MFD using NMEA2000 (use the Marine MFD App instead to see the same data!):
+This PGN is not supported by Raymarine:
   * J1939 - AC data
+When the NMEA2000/STNG network has GPS data, the GX device sees this as a GPS source and is able to use the GPS position in VRM.
+=== 7.2. Instancing requirements when using Raymarine ===
+Fluid instancing details:
+    * Raymarine i70: max number of tank levels is 5; fluid instance 0-4 and type must be fuel.
+    * Raymarine i70s: max number of tank levels is 5; fluid instance 0-4 and type must be fuel.
+    * Axiom MFDs: per Lighthouse version 4.1.75, a maximum of 16 tanks can be connected; fluid instance 0-15.
+==== LightHouse 4.1.75 and newer versions ====
+As of LightHouse version 4.1.75, the battery instances no longer need to be unique. This means that you can leave the battery instance to its default value, which is typically set to 0. The batteries are automatically detected by the Axiom display.
+==== LightHouse 4.1.74 and prior versions ====
+If there are more than 1 (for example) SmartShunts in the NMEA2000 network, or a Solar Charger and a SmartShunt, or any other device that transmits the same type of PGNs, then the Data instances of those PGNs need to changed to make each data instance unique.
+Typically this concerns the Battery instance, used in the Battery Status and DC Detailed PGNs.
+See here for how to do that: [[https://www.victronenergy.com/live/ve.can:changing_nmea2000_instances|Changing NMEA2000 Instances]], section Data instances. This requires an [[https://actisense.com/products/ngt-1-nmea-2000-to-pc-interface/|Actisense NGT-1 NMEA to USB interface]].
