I agree with Steve. I am using similar setup with Shipmodul coverting
SeaTalk to
NMEA.
NMEA to
SeaTalk is not possible. If you want routedata on your
Raymarine repeater you should check if you have a Raymarine
autopilot with NMEA port, like ST260. Connect a output from your Shipmodul to this port and everything will be working.
Due to MacENC shortcoming you need a Shipmodul with USB for this. MacENC is only repeating routdata through USB. For the
WiFi setup you will use a Shipmodul with ethernet and set your gps in MacENC to 'ip only'. Repeating routedata is then no longer possible. May be 2 Shipmodul? Anyone has a better solution?
