This NMEA2000 drop cable connects a VE.Bus product, such as a Multi or Quattro, to an NMEA2000 network. It transmits monitored data, such as AC voltage and current values, DC voltage and current values, as well as status information. Other NMEA2000 devices can also send commands to the VE.Bus product to turn it on or off or to adjust the input current limit. This interface cable is outdated. Instead, use a GX device, as it offers more and better functionality.
