Hi Stuart,
Sorry - missed the second screen shot and I see you have also tried NMEA. There are three crucial settings for this:
- The protocol (which probably should be TCP)
- The Host - this is the IP address of the Emtrak
- The port - this needs to match that used by the Emtrak
The values you need will be found either in the Emtrak manual, or in the settings for Navionics (since this is working they must be correct there), or on the internet.
I am not sure exactly what model you have, but I found this article which suggests the following:
Protocol: TCP
IP address: 192.168.2.1
IP port: 5000
Try putting these into Settings, the slide the Connected button to on. If it's working you will see the GPS and AIS activity lights flashing.
Best wishes,
Bill
