If my memory serves me right when you turn one E-80 in a master and the
other a slave the Sea talk connections on the slave turn off. Hence
you have to run all your seatalk connections to the Master e-80. On my
Beneteau , the initial system had the GPS sea-talked to the charft
table E-80 and the wind/depth/spped instruments connected to the helm
E-80. I found I could have either GPS data or wind/depth/temp.

It could be thats your problem.

I have dual E-80's. One at the helm and the other at the nav station.
My Raymarine E-80 isn't receiving boat speed & wind information from my
other Raymarine instruments. Some of the E-80 functions are effected,
such as MARPA.

It's not practical to chase down wiring issues for a few weeks at
least.

1) Is there a quick fix to tell my E-80 to use SOG (from GPS) instead ?
2) Is there a way to get my E-80 to display traffic it see's on the bus
connected to my other instruments ?
