- | ===== 4. Color Control GX & NMEA 2000 ===== | + | NMEA 2000 defines three different instances: |
- | * The VE.Can port on the CCGX only reads information from the N2K network. It does not (yet!) send any data out on the N2K network. | + | * Data instances |
+ | * Device instance | ||
+ | * System instance | ||
+ | === When is manual configuration of instances needed? === | ||
- | ===== 5. FAQ ===== | + | * 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. |

- | === Q2: Can MPPT Solar Chargers with a VE.Direct port also be connected? === | + | A NMEA 2000 CAN-bus network needs to be laid out as in a backbone configuration, |
- | No, they cannot be connected. Even though the [[https:// | + | * Use the NMEA 2000 cable as the backbone. |

- | === Q3: What about terminators and network | + | * Have the NMEA 2000 network |
- | A N2K canbus network needs to be laid out as in backbone configuration, using drop cables | + | The first option is more aligned with the official NMEA 2000 method. But, in case of multiple Victron products that need to be connected to the NMEA 2000 network, will require more wire runs and definitively more NMEA 2000 to VE.Can conversion cables. |

- | === Q4: What PGNs does the Color Control GX transmit on N2K? === | + | 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. |

+ | ==== 3.5 Galvanic isolation ==== | ||
+ | |||
+ | When connecting a GX to an NMEA 2000 network, it is recommend to do so using a galvanically isolated CAN-Bus port. | ||
+ | |||
+ | This is especially the case when your NMEA backbone and GX are powered from separate power sources or do not share a common ground. These are the two most popular models that feature such galvanically isolated port: | ||
+ | |||
+ | * Cerbo GX MK2 (launched in 2024 as a successor to the Cerbo GX which did not feature an isolated port) | ||
+ | * Ekrano GX | ||
+ | |||
+ | On both above products, VE.Can port 1 has galvanic isolation. VE.Can port 2 does not. | ||
+ | |||
