+Note that both with or without above modification, powering the monitoring equipment with the AC-out of an inverter/charger (ofcourse) has the disadvantage that all monitoring is shut down when there is a problem that causes the inverter/charger to shut down. Examples are Inverter overload, high temperature or low battery voltage. It is therefore recommended to power the GX device from the battery.

-=== 1.4.7 NMEA Tank senders from other manufacturers ===
-A tank sender must meet the following requirements to be visible on the CCGX:
-  * Transmit the NMEA2000 Fluid Level PGN, 127505
-  * The NMEA2000 device class needs to be 'General', 80
-  * The NMEA2000 function needs to be 'Transducer', 190
-Since v2.17 the following functions are accepted as well:
-  * The NMEA2000 device class 'General', 80 and function 'Sensor', 170
-  * The NMEA2000 device class 'Sensors', 75 and function 'Fluid Level', 150
-A single function reporting multiple Fluid Levels is currently not supported.
-For some tank senders it is also possible to configure the capacity and the fluid type from the CCGX - for example the Maretron TLA100. This facility may be available with other senders made by other manufacturers - it's well-worth trying.
-To connect an NMEA2000 network to the VE.Can port on the CCGX, use a [[https://www.victronenergy.com/cables/ve-can-to-nmea2000-cable|VE.Can to NMEA2000 cable]].
-Alternatively, instead of a VE.Can to NMEA200, you can use a 3802 cable from Oceanic Systems: https://osukl.com/ve-can-adaptor/. The difference is that it lends itself well to connecting a single NMEA-2000 device into a VE.Can network. It's also able to power a lower voltage NMEA-2000 network directly from a 48V Victron system.

+To connect an NMEA2000 network to the VE.Can port on the CCGX, which both have different type connectors, there are two solutions:
+  - The [[https://www.victronenergy.com/cables/ve-can-to-nmea2000-cable|VE.Can to NMEA2000 cable]]. Which by either inserting or leaving out  the fuse allows to either power the NMEA2000 network with Victron equipment, or not. Take note of below warning.

+**Warning and solution for 24V and 48V systems**
+Whilst all Victron components can work up to 70V input on their CAN-bus connections, Oceanic and Navico senders cannot. They require a 12V powered NMEA2000 connection, as that is what they use to power their sensor circuitry. See above 3802 VE.Can Adapter by OSUKL for a solution.

 Since both functions transmit the same PGNs, for example an AC Status PGN containing voltage, current and more information, NMEA 2000 data consumers like generic displays will need to be able to make a distinction
 based on the network address. Depending on the function belonging to that network address the need to interpret it as either Inverter Input or Inverter Output. Displays not being capable of doing so will regard the data as belonging to the mains (utility). The Inverter Output is then interpreted as utility #0 and Inverter Input as utility #1. These default instance numbers can be changed by a network configuration tool if necessary.
