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
(for example: depth, apparent wind angle and speed, time).
Note: The Fishfinder uses its own depth data, rather than any other depth data
on SeaTalk. If there is no other depth data on SeaTalk, Fishfinder depth is
transmitted. If speed and temperature data are available on SeaTalk the Fish-
finder uses this data; if this data is not on SeaTalk from other instruments, it is
transmitted by the Fishfinder.
For details of received data refer to the table in Appendix D: SeaTalk and
NMEA Data . Examples of SeaTalk and NMEA systems are shown in
Figure 2-16 and Figure 2-17 .
