[CA] [CA11] Water Temperature Conflict

[Chuck - Raymarine - Moderator]

Welcome to the the Raymarine Forum trush640,

With regard to MFDs, Data Mastership only applies to MFDs which have been interfaced to one another via Ethernet communications. Please note that MFDs running LightHouse II software (e127) and those running the LightHouse 3 operating system (Axiom) cannot be simultaneously interfaced/operated within the same Ethernet network. However, MFDs running LightHouse II software and those running the LightHouse 3 software may simultaneously be interfaced as spurs to the system's powered and properly terminated SeaTalkng / NMEA 2000 backbone.

Based upon the information provided, it appears that the thermistor of the Airmar transducer is failing. Within Raymarine systems, instrument sources of water temperature (such as that from the Airmar transducer which has been interfaced to your Vessel View system) are prioritized higher than fishfinder sources of water temperature within LightHouse II and LightHouse 3 software. As the Data Sources feature of LightHouse II and LightHouse 3 software does not support source selection for water temperature, the system will continue to use the water temperature data from the Vessel View system as long as it is present. Accordingly, the only way to cause the system to display water temperature from the RV-212 transducer would be to disconnect the faulty transducer from the Vessel View system.
