I've been asked a couple of times for a geek tour of the boat. All I can say is be careful what you ask for.... Let me know if this is what you like so I can do more, do less, do something different, or not quit my day job....

Great tour. Overall a great blog. Very interesting to see also all the problems one might encounter.ReplyDelete
For me it was quite surprising how low the quality of some of this essential equipment is, specially when it comes
to interconnecting different devices.
Really appreciate the level of detail you have put into this video. Such a wounderfull job you have done with this system. I understand the frustration you can have getting multiple manufacturers and some times the same to play nice in the sandbox. Thank you again for the videos and I look forward to more in the future.ReplyDelete
Thank you very much for the walk through and the commentary. Great also to see the whole package (I may have occasionally forgotten this stuff is meant to pilot a boat :)) in her element.
A previous post indicated there were still some gremlins on the N2K bus with regard to instancing, leading to the autopilot not getting a 10 Hz heading. Any improvement since then?
Finally, do you have some sort of concentrator for your video streams to interface them to the computer?
Glad you (and others) enjoyed the walk through.
I am still having some issues with N2K, but I don't recall any that interfere with getting 10hz heading to the pilot. But I'm probably just not remembering. The issue I'm working now is some interaction between Rose Point's N2K adapter and Furuno's NavPilot. The NavPilot is doing some things that make no sense and are disruptive on the bus, and perhaps even include a malformed PGN. Then, in the presence of the NavPilot misbehavior, the Rose Point adapter appears to misbehave as well. We will get it sorted out in time. Rose Point is all over it, as it typical of their attentiveness. Furuno is a litle harder to rally, but as of today I have a new trace that pretty clearly shows the issues.
You mentioned the problem here:
Something about a bus storm every 10 seconds which occasionally prevented the heading information to propagate often enough?
This is a good discussion, so I've moved it to a post of it's own over here http://www.mvtanglewood.com/2015/06/nmea-2000-weirdness-continues.html.
As for the video concentrator that you asked about earlier, there is none. The Cameras are all IP network cameras so just have 1Gb Ethernet running back to a Cisco Gb Ethernet switch for the boat's network. Power is delivered over the ethernet cables, so very convenient. I went with Gigibit to ensure there are no network bottlenecks, and so far it has worked well. The Mac also connects to the same network and the app that I'm using decodes and displays the video streams. Everything on the network that is part of the boat is hard wired with fixed IP address. Wifi works well most of the time, but not always, and I want always. The only things that use wifi are our personal laptops, ipads, and phones.
These videos are great. I love going through the technical aspects of these boats, the more the better!ReplyDelete
Excellent tour. Thank you. I am going to have to read some of your earlier blog posts to understand some of the"why"ReplyDelete
