Thanks for these great comments. Responding to a few of the comments and questions.
Plugging the VHF
into the backbone: my vhf is an ICOM
506 which is a DSC
with AIS receiver, it has it’s own GPS antenna
. I prefer to leave this as a stand-alone and as a backup GPS
and AIS. I don’t believe it adds anything by plugging it in to the backbone. Maybe I am missing something.
Power feed to SeaTalk NG network: in my diagram this comes from the ACU 400. This example is shown in the documentation
for the ACU units. Others may wish to add their comments
SeaTalk NG to NMEA
200: yes, as has been pointed out the correct adapter will be need to attach the VESPER AIS.
Backbone terminators: yes these will be needed namely the blue caps ( was tricky to draw on the diagram)
Position of the power unit ( presumably “Frankly” is referring to the ACU 400): I think positioning is a bit of a trade
off. This needs to protected from the elements and be accessible to view. I’ll rethink positioning, although it may be easier to have significantly larger cable to overcome any voltage drop. Other thoughts?
Finally I would love to know if an i70s plugged in to the backbone will work. Anyone?
Hope this thread helps others.
