The way the source selection is processed and presented varies
on the different SimNet Class 1 products.
The individual product manuals will explain this in detail.
A network containing at least one SimNet Class 1 product is
referred to as a SimNet Class 1 system.
SimNet class 2 products
These are SimNet products with limited or no display capability.
They will automatically select the first available data source on
the network, lock onto that source and store it for future use. In
larger systems where a Class 1 product is present, Class 2
products will default to and follow the automatic (or manual)
selections made for the Simrad group by the Class 1 product.
A network containing no SimNet Class 1 product will in the
following be referred to as a SimNet Class 2 system.
Simrad group or stand alone configuration
Simrad group objective:
− To ensure that all products within the group use the very
same data source for each DataType.
− To make it easy to change data source for the entire Simrad
group of products.
− Provide automatic or manual source selection when
appropriate.
Note ! When one or more SimNet Class 1 product(s) are connected to
the bus, the one that is activated for automatic source selection
will establish the Simrad group. All other Simrad products will
join the group as default and use and present the same data.
It is possible to stay outside the Simrad group, i.e. “Stand alone”
with a single DataType or all DataTypes. This feature is useful if
you want to monitor one particular data source, e.g. a gyro
compass using an IS12 MEGA instrument as display.
In such cases you “exclude” the display from the group by
selecting the IS12 MEGA as a “stand alone” in the IS12 setup
procedure.
