The Vesper specs are very clear about it's ability to output, via NMEA0183, NMEA2000, WiFi
, and USB, GPS position data. As I am allergic to NMEA0183, it will be my ability to figure out the proper connections that will be the weak link.
I would normally have the Vesper Vision on all of the time and it has it's own dedicated Vesper external antenna
, so I wouldn't rely on the other GPS receivers
on my NMEA 2000
network for position data. The Vision always displays position data, regardless of the mode it's in.
Also, I might include the ICOM
into the Vision's NMEA0183 GPS connection. This would negate the need for powering up the NMEA2000 network to provide the VHF
with position data.
If this doesn't work ( though I don't see how it couldn't ), I'll buy another Garmin
Your proposed solution will work. I do the same for the reasons you cite, only tapping my Vesper Watchmate 850 [the model prior to the Vision...]
We also have 3 other compatible sources of NMEA 0183
GPS data which I can manually rewire to if the Vesper ever failed, but unless I install failover switches, this would not be viable in an emergency
In case you don't already have the separate DSC
[looks like a VHF masthead antenna but tuned to the DSC
Rx freqs] required for emergency
DSC comms with your 802M, Dockside also sells that in a kit for about the same cost as what I could put together myself... [I have no affiliation nor incentive for recommending Doskside other than being a satisfied customer. There are likely other sources as well...]
Best wishes completing your project
