Expedition data over Wifi to n2K (Garmin GNX 120)

I have a setup with a B&G H5000 processor connected via ethernet to a wifi router. Expedition is connected to the wifi router and H5000 via websocket.

I'm thinking about adding Garmin GNX 120 displays, what are my options to display Expedition custom data on the GNX displays without having a physical PC connection? My PC is a rugged laptop.

You would need a second connection. If you have a fixed connection, this is as simple as adding an Actisense NGT-1 USB. I personally think this is a good idea anyway for GPS and AIS data.

For WiFi, the Actisense W2K-1 is essentially receive only at this point, but I believe the Yacht Devices Wifi gateway would do it. I would have to confirm that with testing unless someone else can confirm it.

Thanks - what do you think about plugging an Actisense NGT-1 USB into a wifi router USB port or plugging a USB Hub like https://www.deltaco.se/produkter/signalhantering/usb/hubbar/3-portar/USB-H3 into the ethernet port of the wifi router - and connect the NGT-1 to the USB hub - would I be able to access it from the same wifi?

It may, but I haven't tried anything like that.

Another option is the -ISO version of the NGT-1. Then you can connect it to a serial to Wifi adaptor such as a Moxa. The Yacht Devices solution may be simpler and cheaper though as it is just one device.

Update. Have had confirmation from 33-South in Sydney who do a lot of this.

Both Yacht Devices and the NGT-1-ISO & Moxa combination work well in this scenario. The YD may be better suited for smaller boats.

They also confirmed my instinct to avoid USB for this scenario.

Thank you so much for digging! I've used a Yacht devices wi-fi gateway for years as a one-way data source ... I see now I can set it bi-directional - if it works it will be a perfect solution =)

There are a couple of comments on YD in the Expedition help.
