[CA11] es78 Lighthouse II settings - Temperature Off-Set, Heading & Heading Line

[Chuck - Raymarine - Moderator]

JeepSWAG,

Of the equipment which you have listed, none are capable of sensing heading. Accordingly, instead of enabling the Heading Vector, you should have enabled the COG Vector. I would also recommend that the Vectors Length setting initially be configured to Infinite. Finally, the system will have no valid COG until underway and making way at a speed of at least 2kts. Accordingly, under conditions when the vessel's position will be rendered as a black dot rather than a vessel icon, it should not be expected that a COG vector will be displayed.

If connected to a NMEA 2000 backbone, it is quite possible that the system features another temperature sensing device. This may be verified by switching the equipment OFF, disconnecting the fishfinder transducer, switching the equipment ON again, and then determining whether water temperature is still reported or is dashed. Water temperature data from a NMEA 2000 source will be prioritized over that from the fishfinder and cannot be offset by the MFD. Any such corrections would need to occur directly to the NMEA 2000 source.

Regarding the temperature issue, ensure that the data item's label is "Water". If not, then the incorrect data item has been selected to be displayed. If so, then what numerical value is being displayed?
