MacENC is very flexible in interfacing to NMEA data sources. Typically when using a Multiplexer you select the port of the Multiplexer in the GPS panel Settings drawer, you then select "Use GPS Port" in the Instruments panel Settings drawer and if you have an AIS or RADAR interfaced to the Multiplexer you do the same in the AIS/RADAR panel Settings drawer.

One can quickly see what NMEA data sentences are coming into MacENC simply by opening the GPS, Instruments or AIS/RADAR panel Monitor drawer and press "Start". NMEA data sentences in green are those processed by the respective panel. Yellow indicates ignored by the respective panel.

A summary of the NMEA sentences that MacENC supports is here..
