The Cap'n, our nav software, connects to COM3 (the VSP fake serial port) and doesn't know the difference. I can connect up to 255 computers to the Webfoot's IP and have had 4 connected simultaneously it feeds data to.

Larry you are one funny guy.
Dont get me wrong, I love ethernet on the boat, and would like MORE things to be ethernet. I get the weather/radar/chart on the chart-plotter, like you said, why not make it available as a stream for my slate? But nmea isnt for moving large UI stuff, streaming video, etc, its for sharing data. So I am cool with having a small CAN bus for heading, temp, wind, dsc, blah blah blah. But I would prefer ethernet for things like radar images. Hows that Noland unit working out? The USB unit looks nice, I am in the market for such a device, but would prefer one with NMEA filtering. Does the Noland filter? It doesnt look like it from the web page.For readers other than Larry: http://www.nolandengineering.com/nm42u.php |

Without getting to the extreme "cyber-space-boat" do you know of a cheap
device/gateway that in some way make the CAN-net interface on my Gramin 292 usefull for communicating either with the brookhouse nmea hub, seatalk or my PC ?? Do anyone know if the Garm292 can communicate on the nmea/garmin port and the CAN-net at the same time. Don't seem to find much CAN information in the manual .... Bjarke "Larry" wrote in message ...

Bjarke, whats the actual problem that you are trying to solve? Cant you just use the nmea output and fan it out? As I recall an nmea output port can handle four devices, If you already have four listeners, you can use something like the device that larry uses ( http://www.nolandengineering.com/nm42u.php ) is there something that the can port supports that the older style nmea doesnt?

Well basicly that the 292 (opposite the old 182) only have one NMEA/Garmin
port, which require one constantly to switch between NMEA mode (for normal operation) and Garmin mode for up and downloading of routers/waypoints and tracks to mapsource or whatever application your are using for that. I'm in the process of evaluating to use a brookhouse nmea hub to connect my Garm292, pc, seatalk (wind, speed, depth), vhf and a new AIS blackbox, I'd like to get AIS information on the Garm292 apart from ofcause to be able to control the Gram292 from the PC for up/downloading. Could be nice if I could keep the NMEA port on NMEA and do the Garmin stuff to the PC via the CANnet interface ... But the other way around might do as well ??

It doesnt look like it from the web page.For readers other than Larry: I'm dragging my feet installing the USB Noland Geoffrey bought. It's a logistics problem on Lionheart. There's a wireway overhead the passageway from the helm station inside the cabinet over the galley to the nav station on the starboard hull that's just STUFFED with all this stuff. Designing with NMEA 0183 in mind, I installed a 25 pair cable (also because I got it free on a 500' spool..(c The RS-232C connected Noland is wired into this station-to-station cable and serves us well. USB is another matter being much faster. I can't get away with this cable on USB, so would have to completely rewire the network through the 25 pair cable and put the new Noland at the nav station, instead of where it is, now. I'd also have to buy an adapter from its USB to RS-232C to connect it to the wifi Webfoot Ethernet adapter or lose wifi all together. We gain nothing with the new Noland. I may use it to increase the input by daisy chaining it onto one of the old Noland ports. My captain bought it because the guy who sold him a new AIS receiver said he needed it to connect AIS to the system at 38,800 baud. Of course, it doesn't INPUT 38,800 baud...only outputs 38,800...rendering it useless for that. The USB adapter will have to be between the AIS receiver and a USB port on the helm station computer, I think, so AIS will input to The Cap'n nav software. We're still discussing its installation. He doesn't like the self-contained AIS he bought, first, because you can't really see where the targets are on its tiny LCD screen as there's no chart, of course. There's also no output data from it to connect to the NMEA network. The new receiver doesn't output NMEA AIS data, either...just 38,800 baud RS- 232C which I THINK, but don't yet know for sure, if The Cap'n can read. It says it can, but it said other things it can't either. Noone asked me about buying it. It just appears with, "Can you make this work?"....(c; He loves his toys...We're gonna need bigger batteries... (c; |

Of COURSE not! All this NMEA 2000 is REALLY a plan to SELL MORE BOXES! All old boxes are all, now, obsolete and will have to be replaced at great expense on all boats with rich owners. Nothing will interface with CANbus you have now and everthing will be done to keep it that way so you can trudge off to Waste Marine for more Waste. NOTHING is gonna be "cheap"! What we need is about 8 more proprietary Raymarine H6, Seatalk, Seatalk 2, GarminTalk, NMEA, CANbus, B&G h2000, B&G h3000, B&G Network, Furuno Navnet vx1, Furuno Navnet vx2, etc., data interface systems that can only talk to each other if we buy a $150 "box" which PARTIALLY converts SOME of the data between them you don't need. One of the reasons computer manufacturers get so rich is they have enough SENSE to make SURE their box will plug into anyone else's box with full functionality....except Apple, of course. One of these days, affluent boaters are gonna wise up..... |
