HEADING SOURCE SELECTION
The H3000 System can accept heading data from a variety of different
sources. These different sources are known as Nodes and allow the system
to identify which heading devices are connected to the system.

DAMPING
Another important facility that you need to be constantly aware of is the
damping available on certain functions. This allows you to filter signal
noise on the function when in unstable or rough conditions.
The damping works by applying a filter over a time period; the more you
increase this time period, the smoother the data readings will be, but the
longer it will take to see the effect of any change. Similarly the lower the
time period the greater the jumps you will see in the numbers, but the
response to any change will be faster. It is recommended to use the
smallest value which still gives stable data.
DYNAMIC DAMPING
Dynamic Damping adjusts your system to deliver the most accurate and
real-time information, i.e. when on a beat, it is essential that the wind
angle information is accurate but steady with most ‘noise filtered out,
however, when tacking, data needs to be more real-time. With Dynamic
Damping, the damping value applied will reduce to almost zero during
conditions when the data is changing rapidly and then settles again after
the tack.
The Damping value is set (in seconds) to a steady state value, the
Dynamic Damping is set to a value between 0 (off) and 10 (maximum),
the higher the value, the more sensitive the function is to rates of change,
and the faster the damping value is lowered.
This allows the effects of the change to be more readily seen on the
instruments. As the rate of change of the function reduces, so the damping
