Multiple data sources (MDS)
The Micro-Talk gateway is MDS compliant. If a data type is available on the Micronet network then
the gateway will be selectable as a data source, for that data type, from SeaTalkng ® displays.
In installations where multiple sources of the same data type exist on the Micronet network, the
data source that is used by the gateway and transmitted on to SeaTalkng ® will be the same data
source that is displayed on Micronet displays.
In installations where the same data types exist on both networks then the MDS selected data source
will be shown on displays on both networks.
If MDS is set to
Auto
then the gateway will be the preferred data source.
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.
Micronet
Micronet is a proprietary wireless Radio Frequency (RF) network protocol compatible with
Raymarine’s wireless range of instrument displays and transducers.
Micronet can be used to connect up to 32 compatible devices together to create a wireless marine
electronics network. Micronet products can operate on 1 of 2 frequencies depending on geographic
location:
• 869.8 MHz for products operating in the UK, Europe or Africa
• 915.9 MHz for products operating in the USA, Canada, South America and Australia
Micronet products comply with the relevant ISM regulations and are exempt from licensing in each of
these territories.
