[TG] Axiom 12 not receiving chart & other data from eS75 MFD as master

Axiom 12 not receiving chart & other data from eS75 MFD as master
Hello Chuck and all:
We have an issue with our Axiom 12/Lighthouse 3 MFD (model #E70368/serial #0670403). Just prior to the Annapolis commissioning our new boat in November 2017, the Axiom 12 was purchased and professionally installed at the aft end of the cockpit table – and, through a HS5 Seatalk Network Switch, iTC-5 converter and AIS 100 Splitter, linked into the existing/original system of an eS75 7” MFD; a P-70 Control Head; two i70 instruments and AIS 650. The eS75 MFD served as Data Master using Navionics cards, sharing chart info with the Axiom 12.
Everyone got along fine for six months, with the Axiom 12 replicating chart details from the eS75. But this month the Axiom 12 seems to have rebelled. Now it displays only rough shapes of islands and other geographic features and shows no depth, contours, bearings, or other navigation visuals (see attachments). Also, after nearly every power-down, we must manually enter the on-board Raymarine data sources for the Axiom to show the basics of current depth, wind speed and direction, etc. in a data-only display. That would seem to indicate that the Seatalk network and connections are working to at least some extent. However it seems that the Axiom needs to be “told” to accept information from the eS75 as Data Master as before, but I have not discovered how to do so through component manuals, research online, and reading forum entries to date.
With the Axiom 12’s larger size and central position between helm stations (AND having paid a considerable sum for it), we want to restore its full chart features. Our sailboat now is based in the Caribbean (Grenada), where technical electronics expertise is hard to find and schedule. So we hope to receive guidance through this forum that will help.

What version of software are you running in your system? We know that there were problems with LH3 intermittently failing to read Navionics chart data but they should have been resolved in latest LH v3.5.40 software, released last month.

You can see your current software version and check for an update online (through marina wifi or a portable hotspot) through Home > Settings. If it is already 3.5, please let us know, but as it is, I think updating to 3.5 will probably solve the problem.
