[CA] [CA11] Integrating VHF and AIS to Classic E MFDs

[folkmeister]

We have E120 at the helm and E80 down below, connected via Ethernet hs. We recently installed an AIS, which is integrated via NMEA 0183 to the E80. This required us to disconnect the VHF radio NMEA connection to the E80, as the E80 has only one NMEA port and it had to be changed from 4800 to 38400 baud.

What is the best way for us to re-establish 4800 baud NMEA connectivity (multiplexer to some other method) from our network to the VHF?

1) can the nmea baud rates be different on each of the plotters, in a data master / slave configuration?

2) Is the NMEA port active on the “slave” MFD?

3) Is the Seatalk1 port active on the “slave” MFD? I believe the answer to this is no...
