[CA] Issues with Networked Axion 9 Units

[Chuck - Raymarine - Moderator]

Wstandis,

The Axiom MFDs are designed to share cartography, radar, fishfinder, thermal camera, satellite weather, and IP camera resources when interfaced to one another via an Ethernet network. The same cannot be accomplished via by simply interfacing the MFDs to one another via a powered and properly terminated SeaTalkng / NMEA 2000 backbone. When so interfaced via an Ethernet network, the MFDs will also share pages. Accordingly, should the operator configure the full page Fishfinder application displayed by the pre-configured Home screen's Fishfinder application page icon, then any changes made to the sonar channel selected will also effect the Fishfinder application of another one of the system's MFDs displayed by selecting the same Fishfinder application page icon on the Home screen. Should one desire to display DownVision sonar on one of the MFDs and high CHIRP sonar on the other MFD, then it would be recommended that the page icons of Home screen be modified to include two full screen Fishfinder application page icons ... one will be titled DownVision FF and the other will be titled CHIRP FF ( or FF Page 1 and FF Page 2, etc.). After doing so, the operator will select the Home screen's DownVision FF page icon and then configure the displayed FF page to display the DownVision FF channel. After doing so, the operator will select the Home screen's CHIRP FF page icon and then configure the displayed FF page to display the high CHIRP Sonar channel.

Regarding the GPS performance issue reported, please indicate whether the MFDs have been installed in a location affording at least one of the MFDs a clear view of the skies overhead and that the MFD's Data Sources feature has been configured to specify that the MFD satisfying the installation location described above has been designated as the system's source for GPS data. If interfaced to an external GPS sensor (ex. Raystar 130, Raystar 150, etc., then the external GPS sensor should be specified as the system's GPS data source).

Regarding the Chart application defaulting to 2000 ft., should the system not have acquired a GPS position FIX, then this will be the default range when the Chart application is displayed. Should the MFD have acquired a GPS position FIX and should a Chart application page be closed, then the next time that the SAME Chart application page (see the response above concerning sharing of the Home screen's page icons) is opened, the Chart application should revert to the same range level as had been previously viewed.

Please additionally note that the LightHouse 3 v3.5.40 software update appears to have now corrected all Navionics chart sharing issues which we are presently aware of. Accordingly, should your MFDs be interfaced to one another as specified above and should the MFDs not presently have been updated with LightHouse 3 v3.5.40 software, then it would be recommended that this action be taken to address any cartography sharing issue(s).
