[CA] [CA11] Upgrade options

[serenisea]

Hi,

Our used Seawind 1160 catamaran was well equipped with Raymarine systems when it was new. The components include the E120 Classic MFD, analog Raydome, ST60 Tridata, ST60 Wind, Autopilot 6002, 300 DSM box, Seatalk HS Network box, Smart Pilot Control Box, and SR 100 Sirius Weather box. I also installed a Standard Horizon AIS enabled VHF to it via the NMEA 0183 system and all worked well.

The backlights went out in the E120 classic, so due to its age, I purchased a new Es78 Hybrid Touch MFD to replace it. I know the analog Radome will not sync with it, but not sure about which way to upgrade using the existing systems. I upgraded a previous boat with ST50 instruments using the Seatalk to Seatalk NG converter to a new E7 Hybrid Touch, and ran the Standard Horizon AIS to interface with it as well.

Given that the new boat has the 300 DSM and Seatalk HS network boxes (the Sirius Weather is not activated), can those networks be used, or should I just do it via the Seatalk to Seatalk NG converter? Enclosed is a rough diagram.

Thanks.
