SeaTalk and NMEA In
The HSB Series display can receive a comprehensive range of data. The
primary data is described below:
Data
Heading
Position
Speed
Waypoint
Heading data should ideally contain both magnetic and true heading. If only one
is available then a source of magnetic variation should be connected.
Some other radars and chartplotters can exchange their cursors via SeaTalk.
Locked heading should be used for Course Up if available via SeaTalk.
Other data connected via a SeaTalk bus or via NMEA is generally displayed in
data boxes, e.g. depth, apparent wind angle and speed, time.
