Welcome to the Panbo Marine Technology Forums.
I've got an existing SeaTalk NG network on my boat (Tartan 3800) and have installed a Vesper Cortex AIS/VHF and a Fusion Marine MS-RA70NSX. Both have NMEA 2000 ports and I'd like to connect them to my RayMarine network. I see that RayMarine has an adapter for connecting SeaTalk NG devices to a NMEA 2000 network and an adapter for connecting a SeaTalk NG backbone to a NMEA 2000 backbone, but I can't figure out how to do what I want to do. I'd hate to replace the existing network, and because of the way it's been designed/installed, it would be difficult to extend it with additional NMEA 2000 backbone. Thoughts?
Hi Bill, Raymarine also makes adapters to go from a standard N2K device, or cable, to a SeaTalk NG white spur connector. At one end is a male DeviceNet plug and at the other is a white female STng plug. I can't find them on Raymarine's website, but here are some examples:

You may need to add STng backbone cable sections and tee connectors, but you can definitely keep your existing network and add your new N2K devices.

Thank you! I found the connectors. Raymarine doesn't make it easy!
The other option is to take an StNG spur cable, chop off one end and install your own NMEA2K connector. I did that to connect both an Icom M506 and an AirMar UST800 to my StNG network.
