Thanks for all of your help!
Are you investigating the Vesper XB-8000 because you:
1. Need an AIS transponder
2. Need an AIS transponder and also need a NMEA 2000 gateway
or 3. Just need a NMEA 2000 gateway ?
I already own the XB-8000. I sailed with it from Fiji
to NZ in 2019, a wonderful piece of gear
it is. At the time, since we had just purchased the boat
, I used it for GPS
and AIS and broadcast that over Wifi and used OpenCPN on my Android Tablet. All worked really well. I was using the old non-networkable and original analog wind
But now the plan is to really set myself up tech-wise for 3 years of South Pacific
cruising. We will be expanding the NMEA 2000 backbone with a B&G wind
, water depth
and temp sensors and I will also connect a Vulcan 3 9" chatplotter for viewing in the cockpit
. I plan on feeding the XB-8000 GPS
and AIS into this NMEA 2000 backbone. So far this seems A-OK.
But I also want to create a super low power consumption
system for the chartplotter
inside. The "smart boat system" so to speak. I purchased a Raspberry Pi 4 for this and will connect it to a low power
portable 13" HD screen
which I will mount in place. A new digital B&G (or similar) radar
will feed both the raspberry pi/open cpn and the vulcan chartplotter
via ethernet and a network switch in between.
Everything left of the radios will be replaced by a small raspberry pi with a 13" HD portable monitor
which I will mount on a new teak
So both inside and outside systems will use the same data from the NMEA backbone but in a sense I will have redundancy of "computing" and, unlike the chartplotter which sucks a decent amount of power, I plan on leaving the Raspberry Pi ON all of the time as it will also monitor
barometric pressure and potentially freezer
, fridge and engine
room temp sensors. Based on my research
it also appears possible to connect my Victron BMV-702 battery
monitor to the Raspberry Pi via the VE Direct USB cable and I have found a few open source serializng code examples to dump the data in an InfluxDB.
I am using a lot of fancy terms to me, but really I am just getting started with this. But if you're anything like me, I love messing about and learning
new things so this is all good fun. :-)
The one thing I have not been able to find easily online, and the reason for this post, is whether or not I can simply connect the Vesper Marine XB-8000 to my Raspberry Pi via USB and be able to see my NMEA 2000 data (GPS, AIS, Wind Speed, Wind Direction, Water Depth
, Water Temp) or if I need any drivers or anything. I understand the data will flow via Signal K but do I need to do anything to "see" the data or will it all work as-is. Perhaps the reason I cannot find anything online is this is a non-issue.
From the answers on this thread, it seems I can plug
and play and Signal K will ensure the data is displayed to OpenCPN.
Thanks for all of your help, I think when I'm done with all of this I will create a big blog post summarizing my approach. If anyone is interested in one day following our voyages, our blog is alulasails.com We hope to fly back to NZ in the early fall (vaccination dependent I am guessing) and resuming our sailing adventure then. Cheers
