 === Raymarine only: data instances need to made unique ===
-If there are more than 1 (for example) SmartShunts in the NMEA2000 network, or a Solar Charger and a SmartShunt, then the Data instances of the Victron PGNs related to DC power need to changed to make each data instance unique.
+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]].
 **Note**: this requirement of data instances being globally unique for a PGN is specific to Raymarine. Other brands do not require this. And, although perhaps besides the point, also the NMEA2000 standard does not require it. More specifically, it says: "Data instances shall be unique in the same PGNs transmitted by a device. Data instances shall not be globally unique on the network.".
