The

series display can receive a comprehensive range of data. The
primary data is described below:
*Accurate heading data is required for MARPA and radar/chart overlay, and it
must be provided on NMEA. We recommend the Raymarine Rate Gyro
Compass or a Raymarine autopilot system incorporating a 150G or 400G
Course Computer with internal rate gyro.

Compass or a Raymarine autopilot system incorporating a 150G or 400G
Course Computer with internal rate gyro.
Heading data should ideally contain both magnetic and true heading. If only
one is available then variation needs to be provided either manually or
automatically - see Variation Source on page 7-8.

automatically - see Variation Source on page 7-8.
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.
data boxes, e.g. 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.
