Data Displayed
The RayData can display the following additional items of data, if the
appropriate information is available over a SeaTalk or NMEA interface:
• Heading
• Locked heading
• Position, as Lat/Long or TD
• Speed over ground (SOG)
• Course over ground (COG)
• Waypoint number
• Bearing to waypoint (BTW) and distance to waypoint (DTW)
• Time and date
• Cross track error (XTE) distance
• Time to go (TTG), estimated time of arrival (ETA) and velocity made
good (VMG) to the next waypoint
• Boat heading and rudder angle
Facilities
If the primary position data is lost, the RayData performs dead
reckoning calculations from the speed and heading data (if available),
and provides a DR position.
When heading information is available, the heading can be locked with a
simple keypress. The Locked Heading display then shows the locked
heading (Course to Steer) and the actual heading, plus a graphic off-
course indication.
