+==== 3.2 NMEA 2000 instances ====
+Instances are used in an NMEA 2000 network to identify multiple similar products connected to the same network.
-NMEA 2000 Instances are used to identify multiple similar products connected on the same network.
+As an example, take a system with two battery monitors (one for the main battery bank, and another for the hydraulic-thruster bank) and also a Quattro inverter/charger. All three of those devices will send their battery voltage measurements out on the NMEA 2000 network. For the displays to show these values at the right place, they need to know which voltage belongs to what battery. That is what instances are for.
-There are several types of instances, the most important ones being the **Device instance** as well as the **Data instances**.
+There are various types of instances, and for marine systems are two that matter: the Device instance and the Data instance. The Data instance goes by various different names, like Fluid instance, Battery instance and DC instance.
-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]].
+NMEA 2000 defines three different instances:
-=== What settings need to be made? For example instances? ===
+  * Data instances (Battery instance, Fluid instance, and similar)
+  * Device instance
+  * System instance
-That is a commonly asked question. The answer depends on the used brand of MFD:
+=== When is manual configuration of instances needed? ===
-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 **Garmin, Furuno, Maretron and Navico (B&G, Lowrance, Simrad) systems**: no configuration needed. Required fields can be configured and selected on the MFD, usually by pressing and holding on a data field in the data bar until the selection pane comes up.
+  * For **Raymarine**, before selecting the data on the MFD, the Battery and DC Detailed instance typically needs to be set up to be unique. For details, see the [[https://www.victronenergy.com/media/pg/Cerbo_GX/en/marine-mfd-integration-by-app.html#UUID-906e773b-f29c-2b77-56a8-d9ade87cc418|GX manual, Raymarine section]].
-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.
