Click View Data to verify that your computer is receiving AIS data (you must be
in a location where AIS data is available). All NMEA data currently being received
by the computer will display in this window, including GPS and any other NMEA
data output devices connected to your computer. AIS data is in the form of an
AIVDM and AIVDO NMEA sentences (Figure 2.27).

Port Priorities
Port Priorities are used to resolve conflicts occurring when two or more devices
send the same information. For example, different position devices (GPS, AIS, etc.)
may send conflicting Lat/Lon values. Unless you prioritize these inputs, the boat
icon could change position on the chart with each position sentence received.
Data from the highest-prioritized device is used first. If the primary device stops
sending position information (for a user-specified period of time), the software
automatically switches to the next prioritized device. If no valid position is received, you
can manually enable Dead Reckoning mode (see the Jeppesen Workboat Navigator
User’s Guide).
