e7D can only see one Fresh Water Tank

[[email protected]]

How many Instances of Fresh Water Tanks can the e7D recognize under the N2K Fluid Level PGN?

My e7D apparently is only able to see one and I have two Fresh Water tanks to monitor on the N2K/STng network. My N2K network analyzer can easily see both tanks properly configured as Fluid Level/Fresh Water/Instance 0 and Instance 1.

If the e7D design fails to support the N2K Standard and can only recognize one, could I configure the second as a Gray Water tank and fool the e7D into recognizing it that way?


Thanks, Lawrence

Welcome to the Raymarine Forum Lawrence,

Please click here to view a thread in which I had previously addressed this subject. While the NMEA 2000 Standard provides guidelines for assigning instance numbers, it does not specify the number of instances which a product must support. Unfortunately as of LightHouse II v19.03, only one tank each for fresh water, grey water, black water, and live well is supported.
