In order to use an AIS receiver with a Shipmodul Miniplex-41/42BT multiplexer, the AIS receiver must be connected to the RS-232 RX and COMM connectors. The rate in MacENC's GPS panel Settings drawer should be 38400. Use the Miniplex tool to set the mode to AIS. Set "Use GPS Port" in the AIS panel Settings drawer. AIS receivers only work at a rate of 38400. Keep in mind you will not see any AIS NMEA (!AIVDM messages) unless there is ship traffic to receive in your reception range.
