I have multiple tank level sensors connected to a maretron fpm100,measuring 2 fuel tanks and a water tank. The tank level display on the CCGX flashes between a fuel tank level and the fresh water level. In the settings on the ccgx for that sensor the instance number is 30, which is the device instance level set in the maretron N2k analyser, the tank instance numbers are 10 and 11. how to get the ccgx to separate the two tanks into separate displays? There is also a Maretron TLM reading the black water tank and its display is discrete from the fresh and fuel. No problem with that one.
