Twistedtree, I assume that N2KView will read all NMEA messages (0183 and 2000) that the Nemo gateway collects and puts on the NMEA2000 backbone, but that you will need the Maretron gateway USB100 to connect it to the PC?
I'm planning to install some Maretron and Actisense sensors on Monara (Monara - Introduction), want them to talk to my Nemo (still in the box), and understand from this thread that I will need 3 gateways... Nemo, USB100 and NGW-1...
I think that's mostly, if not completely correct. But let me re-state just to clarify.
N2KView can display most N2K messages (PGNs). But it does not process 0183 messages at all. Any 0183 data needs to have been converted to PGNs to be displayed.
The 0183 to PGN conversion can be done by a number of devices, including NEMO, Actisense devices, etc. Just check the documentation very carefully to be sure any particular device will translate the sentences you care about, at the required rate. I found a lot of challenges in this respect. See this article Adventures of Tanglewood: NMEA 2000 to NMEA 0183 converter challenges
Once some device converts 0183 data to PGNs and puts it on the N2K bus, then any connected device has access to it.
N2KView running on a Mac or PC can connect to an N2K bus in one of two ways. You can use the maretron USB100 for an N2K to USB connection. It's the least expensive route, but only supports a single connected device. The other way is with the IPG100. The IPG100 takes N2K data and puts it on ethernet, but in a format only accessible to Maretron. So it's like Nemo in this respect, except the data access over Ethernet is proprietary. The advantage of the IPG is that you can run N2K from any connected system (but only as many instances as you have licenses), and more importantly you can use N2KView Mobile, and that does not require an extra license. Plus you can run N2KAnalyze from any system, all at the same time. Personally I would only get an IPG100 because it is so much more flexible.
Hope that helps.
