Instruments
The Instruments view displays the data (See Datum table below) from either
the Location Services (i.e. GPS, WiFi, cell tower) OR NMEA data coming
from a TCP/IP NMEA Client connection. Selecting any row in the Instruments view
will display the selected data by itself in a large font or in some cases an analog graphic. "Units"
determine the format of the data. Select "Setup"
to filter what data is displayed. When "True Bearings"
are disabled in "Setup", magnetic bearings will be
computed based on the position.
The Compass banner, "HDG:", position icon orientation and course up chart will use the device compass if available AND "HDG:" is "On" in the "Setup" AND Location Services are being used, otherwise COG will be used. Note: The compass measures heading relative to the top of the device. The compass banner will have a yellow background if error is greater than 30 degrees.
To use Location Services, from the home page, select "Settings", "General", "Location Services". Note: COG and SOG computation accuracy are dependent on HPE or in other words a high HPE will result in less accurate COG and SOG computation. Note: "Airplane Mode" does disable the GPS receiver and WiFi reception.
To set up "TCP/IP NMEA Client" enter the host IP address (i.e. 10.0.1.2 or somehost.com) and the host port (i.e. 2114) of the NMEA data server (i.e. MacENC or Coastal Explorer or GPSGate). Enable "Link" to make the connection to the NMEA data server. Select the "Save" button to exit. Position, Speed and Course can come from either NMEA GPS or AIS transponder. In the event the TCP/IP connection is lost, Locations Services will be reverted to. The "Bookmarks" button can be used to recall previous hosts and ports used.
| TCP/IP NMEA Client Setting | When Enabled |
| Disconnect Alarm | Offers an audio and visual alert if the connection is lost. |
| Enable Waypoints | Import and and navigate to active waypoint or route of the NMEA data server. |
| AIS Targets Only | Limit NMEA data to AIS Receiver (i.e. !AIVDM) and Location Services will be used for position, course and speed. |
