Required Additional Components; Seatalkng; Multiple Data Sources (Mds) Overview - Raymarine EVOLUTION EV-1 Installation Instructions Manual

Required additional components

To complete your autopilot system, you will need the
following components and data sources in addition
to the Evolution components.
Essential:
• Compatible autopilot controller (See:
Compatible autopilot
• Drive unit appropriate for your vessel and Evolution
EV and ACU units (See:
• ACU power cable (not supplied).
• SeaTalkng® backbone.
Recommended:
• Compatible speed data source. The autopilot uses
speed data when making calculations relating
to navigation. As a minimum, this information
must come from a GNSS receiver providing SOG
(Speed Over Ground) data, or ideally from a
dedicated speed sensor.
• Compatible wind data source (only required for
sailing vessels). The autopilot uses wind vane data
to steer relative to a specified wind angle. This
data must come from an analog wind transducer
connected to the SeaTalkng® backbone.
• Rudder angle sensor. To ensure optimum autopilot
performance, it is highly recommended that a
rudder reference unit is used.
Note: The system components listed above
are "recommended" because they help to
provide optimum performance for autopilot
systems when used in conjunction with the
"essential" components listed. However, these
"recommended" components are not included in
all autopilot products or system packs. Consult the
Raymarine website or your local dealer for a full
list of the components included with your autopilot
system.
Optional:
• Position data source – The autopilot uses position
data when following routes and calculating the
optimum course to steer. This data is usually
supplied by a GNSS receiver on the SeaTalkng®
backbone.
SeaTalkng®
SeaTalkng® (Next Generation) is an enhanced
protocol for connection of compatible marine
instruments and equipment. It replaces the older
SeaTalk and SeaTalk2 protocols.
SeaTalkng® utilizes a single backbone to which
compatible equipment connect using a spur. Data
and power are carried within the backbone. Devices
that have a low draw can be powered from the
network, although high current equipment will need
to have a separate power connection.
SeaTalkng® is a proprietary extension to NMEA 2000
and the proven CAN bus technology. Compatible
NMEA 2000 and SeaTalk and SeaTalk2 devices can
also be connected using the appropriate interfaces
or adaptor cables as required.

Multiple data sources (MDS) overview

When a system includes multiple instances of a
data source the preferred data source is selected
automatically. The systems preferred source may not
be your preferred source, or if you are experiencing a
data conflict you can manually select your preferred
data source.
MDS enables you to choose a preferred source for
the following data types:
• GNSS Position
• GNSS Datum
• Time & Date
• Heading
• Depth
• Speed
• Wind
This exercise would usually be completed as part
of the initial installation, or when new equipment is
added.
For MDS to be available all products in the system
that use the data sources listed above, must be
MDS-compliant. The system will report any products
that are NOT MDS-compliant. It may be possible
to upgrade the software for these products, to
make them compliant. Visit the Raymarine website
(www.raymarine.com) to obtain the latest software
for your products.
If MDS-compliant software is not available for the
product and you do NOT want to use the systems
preferred data source, you must remove any
non-compliant product from the system. You should
then be able to select your preferred data source.
Note: Once you have completed setting up your
preferred data sources, you may be able to add
the non-compliant products back into the system.
Multiple data source exceptions
With the Evolution system, there are a number of
important exceptions to the handling of multiple
sources of certain types of data.
Specifically:
• Heading data — If a non-Evolution source of
heading data is designated by the user, the
Evolution system components will combine this
heading data with its own gyro and accelerometer
data, and then use the improved heading data.
This combined heading data will also be available
to other equipment on the SeaTalkng® bus.
• Rudder angle data — Where there are multiple
sources of rudder reference information, the
Evolution system components will ignore rudder
angle inputs from any rudder reference units that
are NOT connected directly to the ACU.
