NMEA0183 to SeaTalk1 conversion

Hi,

I am trying to link a Garmin GPS 128, Clipper Depth, and Clipper Log to a SeaTalk1 bus. Is the Raymarine E85001 the right device to transfer one-way data from NMEA 0183 to SeaTalk1?
 
I just bought a boat with some outdated devices, which I am trying to upgrade in terms of functionality.
I have an ST1000+ on board, and I would like to be able to control it remotely via the Navionics app. I came across the Nauti-Control ST WiFi wireless unit with remote—that should be OK in terms of app control, I think.
Now I am trying to get data such as depth, GPS, and SOG into the Navionics app from other devices that use NMEA 0183. My understanding is that if I can find a device that converts this information from NMEA 0183 to SeaTalk1, I could then connect that bus to the Nauti-Control unit, which would transfer the data over WiFi to the Navionics app.
Is this possible to achieve?

Not familiar with the Nauti-Control. The Yacht Devices multiplexor should put everything on the Seatalk bus though.

Unless I am wrong I don't believe you can control any autopilot (regardless of age or network interface) from the Garmin Boating (aka "Navionics") app if that is what you were hoping to do? It can received data from your boat via WiFi but not send data back to the network.

Yes the developer sometimes appears here. It it designed to allow a mobile phone/tablet (or watch) to communicate (using their app) with your SeaTalk1 or ST-NG network.

Navionics can take SOME forms of external data over Wifi for use in the app. I'm not sure what advantage feeding GPS and SOG has over using the in built GPS in your mobile device/tablet. I'm not sure if they can receive and display depth, but it certainly won't use the depth in any useful way so I am not sure there's a compelling reason to do so.

Yes.
to the Navionics app.
You need to check it can actually do anything useful with that data. The only obvious data worth feeding in to Navionics this way is AIS (unless your tablet doesn't have GPS in which case the cheapest solution is probably an upgrade).

There are other apps that can display the data for you.
 
Possibly the Vela-Navega NMEA3WiFI ? It provides two NMEA0183 inputs and a ST1 Bidirectional port. It also provides a WiFi output which would interface to a Navionics tablet say. Your original list was three NMEA0183 devices? - so you may need a multiplexer for two inputs. The other Vela-Navega devices seem to be ST1 input only. Cost is Euro 64-80.

Nmea3Wifi


Edit - it also has a USB inport/output which might work for the Garmin 128 using a serial to USB converter cable.
