Orlando -
I'm a bit confused on how the MBB300C communicates with the Garmin MFD's. Is it via NMEA2000 or the Garmin network (ethernet)?
The Panbo article seems to allude that the device connects to the Garmin equipment via a POE blocker and then to the Garmin network however the Maretron documentation makes no mention connecting in this fashion but rather the ethernet port on the MBB300C is connected to the boat's local area network router.
My boat has a stand-alone local area network with wireless router, Uniquity Bullet long range WAN integrator, and Lorex IP camera system with the Lorex Network Video Recorder. The Garmin system also has an extensive network for much of the Garmin equipment. The two shall never meet.... I have had multiple IP experts on the boat to integrate the Lorex cameras with the Garmin MFD's with negative results.
Then along comes this MBB300C that appears to, somewhat, integrate a commercial LAN with the Garmin equipment however with a single ethernet port it must connect to the boat's LAN and not the Garmin network.
Is, in fact, the Garmin MFD's getting the MBB300C data via NMEA2000? Or is there another way to connect to the Garmin network?
Thanks
Tom

Tom, In short it uses both. It uses HTML5 to display the supported aspects of N2KView in Garmin OneHelm. That part is connected via an ethernet cable with POE power blocker (POE injector) to the Garmin Marine Network (GMN). That is to display the interface only, no control data. The actual control data, PGN 127501 (status) and PGN 127502 (switch control), is done via N2K. To complicate things even more Maretron uses proprietary PGN's as well because thats how they started off, and those above mentioned PGN's have been deprecated to an extent and why they implemented it the way they did. If you have N2KView running on another PC other then the MBB300C it won't work, or so I am told. It is almost cost prohibitive to implement this by aftermarket users or doesn't make any sense to.

For digital switching Garmin has built in support outside of OneHelm that started with the 7600 series. Great Panbo article on this. This version of digital switching can be done for a few hundred not thousand as mentioned in that article.

With regard to your Lorex configuration, if you use one side of a POE injector to block the power, you should be able to connect any GMN cable to the boats wired network. That doesn't mean that the communication will work correctly, Garmin has it's own proprietary protocol it implements. So that mean's the Lorex DVR would not be seen by any of the Garmin equipment. Garmin and Raymarine need Axis equipment. If you have the right Video Encoder by Axis you should be able to use the video output of DVR to an Axis video encoder connected to the GMN and you should be able to view your DVR, but you would need to control the DVR by it's remote only.

Looks like Iris (https://www.boat-cameras.com/product/cmac-camera-alarm-management-system/) has joined the OneHelm bandwagon with analog and IP camera support via integration of its "IrisControl" HTML5 app. I scanned the site and the documentation seems to be scant but it looks like it might be able to serve as a bridge between any type of camera to Garmin. This stuff appears to be quite new; I couldn't find where to actually price or buy any of the gear.

It's my sense that OneHelm is a work in progress with the promise for lots more integration/interface coming.

Al - Thats really cool, very nice full featured system it looks like.

Yeah OneHelm is definitely a work in progress based on most of whit it will support is still being developed itself. At the end of the day it's pretty cool what it will do and does support. But then the question comes up of how much do you want to do exclusively at your helm. I guess like anything else it has it's place.

EDIT: panbo link for the Iris Control system

@ttmott - here is the pinout of the Garmin Marine Network cable. It's basically an ethernet crossover cable with POE support.

As an Edit - we should probably take this discussion to another thread as what @Wishfull Thinkin II was simply asking is lost..... But to close -
Thanks I think I understand all of what you and Al are telling me. Essentially my boat has two IP based networks; the Garmin (managed by OneHelm) and a standard LAN with router, Lorex IP camera system with NVR, and long range WAN to LAN (Ubiquity). What we have found out is the two shall never meet through ethernet connection; the html5 and Garmin security prevents the two from being interconnected. We manipulated the IP addresses of the boat's LAN to the Garmin series and it crashed/locked up the Garmin system. I had the IT "experts" on the boat for several days to work through it but no joy. The first picture is where I tried to interconnect the two systems (Red line) and the Second picture is how it is today (Red lines) so the Fusion graphics and camera and info gets integrated into the Garmin MFD's.
