[CA] [CA11] A57D external alarm capability

[bucky]

revised proposed network to produce external audible shallow water alarm:


p79 transducer provides depth info to A57d mfd

mfd shares depth info to stng network backbone [Raymarine Seatalk1 To Sea Talk-Ng Converter E22158]

depth data from backbone is shared to st50 depth instrument

st50 instrument processes data and produces shallow water alarm

alarm info returns to stng backbone and is then sent to A80614 Seatalkng Auxiliary Alarm Buzzer


is this viable?
this may seem convoluted but i own most of the equipment and would like to avoid buying more expensive parts

thank you bucky
