This display shows the locked heading and the boat heading, in
degrees Magnetic or degrees True, depending on the choice made in
the Setup pages (see Chapter 4). It also shows a steering bargraph,
which provides a graphical indication of the difference between the two
headings.
If the RayData is being used as part of a larger system, with an autopilot
connected to the SeaTalk bus, and the autopilot is in lock mode, then the
display will show PILOT HEADING instead of LOCKED HEADING, and
the locked heading value received from the Autopilot is displayed. Note
that the RayData locked heading does not have any effect on the
autopilot.
