- | Both connections can be made and used at the same time, and each has its advantages and disadvantages. The MFD App is by far the simplest and plug and play-like method. It presents an easy to use system overview without requiring any configuration. The NMEA 2000 integration on the other hand, whilst being more complex, allows more customisation on the MFD: the data will show up in the data-tree of the MFD, and most MFDs then allow the user to configure various pages and combinations of information. This is not so with the MFD App, as the only available settings are to show or hide battery parameters (Voltage, SOC, Current) as well as naming the batteries. | + | NMEA 2000 is sometimes also refered |

- | ===== 2. Varia ===== | + | The MFD HTML5 App is the simpler one to setup as its plug and play. It presents an easy to use system overview without requiring any configuration. The system overview shown will automatically adapt to the type of Victron system installed. The (only) available configuration is defining the batteries as well as giving them names. |
+ | The NMEA 2000 integration is more complex, and allows more customisation on the MFD: the data will show up in the data-tree of the MFD, and most MFDs then allow the user to configure various pages and combinations of information. | ||

- | ==== 2.1 Raymarine & EmpirBus ==== | + | The GX devices can measure tank levels, and make the resulting data available on the NMEA2000 network. Also, they can read tank level data from the N2K network. |
- | Besides using NMEA 2000 and/ | + | Below sections explain |

+ | All tank level inputs feature customisable naming, setting a type (fresh water, fuel, black water and more), configurable filtering and damping settings as well as setting up a custom tank shape for non-square tanks. | ||
- | ==== 2.2 Maretron ==== | + | The GX Device can transmit the resulting tank levels to the NMEA2000 network. See the [[https:// |
- | All data sent out by Victron devices can be picked up by the Maretron MFDs & software. See the [[http:// | + | === Integration B) NMEA2000 to GX Device |

+ | |||
+ | Our GX devices can read location, altitude, speed and course from the NMEA2000 network. For details, see the GX manual. | ||
+ | |||
+ | Note the other way around does not work. A GX Device which has a USB GPS installed does not emit GPS data out onto the NMEA2000 network as part of the NMEA2000-out function. | ||

- | Note that there are many more generic frequently asked questions answered in the [[https:// | + | NMEA 2000 Instances |
- | ==== Q1: What about instances? Device instances, data instances? ==== | + | There are several types of instances, the most important ones being the **Device |

- | ==== Q2: Can MPPT Solar Chargers with a VE.Direct port also be connected? ==== | + | === What settings need to be made? For example instances? === |
- | No, they cannot be connected. Even though | + | That is a commonly asked question. The answer depends on the used brand of MFD: |

+ | |||
+ | A N2K CAN-bus network needs to be laid out as in a backbone configuration, | ||
* Use the NMEA 2000 cable as the backbone. | * Use the NMEA 2000 cable as the backbone. | ||
- | * Run a separate drop cable separately to each Victron device. The drop cable will be one of these three products: | + | * Run a separate drop cable separately to each Victron device [[https:// |
- | * [[https:// | + | * Only terminate the NMEA 2000 backbone. Do not install a terminator in any of the VE.Can ports on the Victron products. |
- | * [[https:// | + | |
- | * [[https://nocache.victronenergy.com/ | + | Or: |
- | * Only terminate the NMEA 2000 backbone, do not terminate | + | |
+ | * 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. | ||
+ | |||
+ | 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 ==== | ||
+ | |||
+ | The Victron VE.Can network accepts 9 to 70VDC. | ||
+ | |||
+ | 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. | ||
+ | |||
+ | 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. | ||
+ | |||
+ | Therefore, it is important to **not** connect those power cables. | ||
