[GPSNavX]

The only way you can get something to the output port on the Miniplex lite is to have GPSNavX or MacENC repeat to it. The Miniplex lite does not operate as a hub. It only operates as a server. This means your Mac must be sending NMEA data to it. MacENC and GPSNavX can do this via the repeat port.

So whatever comes into the GPS Panel port will be sent to the repeat port (assuming one is selected). If you check "autopilot only" then only those NMEA sentences for the activated (i.e. Goto button) will be sent the the repeat port.
