2.5 Multiple data sources (MDS) overview

Installations that include multiple instances of data sources can
cause data conflicts. An example is an installation featuring more
than one source of GPS data.
MDS enables you to manage conflicts involving the following types
of data:
• GPS Position.
• Heading.
• Depth.
• Speed.
• Wind.
Typically this exercise is completed as part of the initial installation,
or when new equipment is added.
If this exercise is NOT completed the system will automatically
attempt to resolve data conflicts. However, this may result in the
system choosing a source of data that you do not want to use.
If MDS is available the system can list the available data sources
and allow you to select your preferred data source. For MDS to be
available all products in the system that use the data sources listed
above must be MDS-compliant. The system can list any products
that are NOT compliant. It may be necessary to upgrade the
software for these non-compliant 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 and you do NOT want the system to automatically attempt
to resolve data conflicts, any non-compliant product(s) can be
removed or replaced to ensure the entire system is MDS-compliant.
