Ockam Hardware
Since
the system
outputs depend on what sensors are attached, the available interfaces
are described in the next few pages.
True Wind
The
most important function of an integrated system is true wind which
requires apparent wind, boatspeed and heading. On the Ockam system,
these sensors are handled by the T2 interface.
If all
systems need these inputs, why not put them into the processor
directly? One reason is that boatspeed and wind are forward, and
placing an interface there makes more sense, and saves considerable weight in cable runs.
Another reason is that
a separate interface uncouples sensor requirements from the
processor design. The classic analog masthead sensor
is giving way to
the sonic sensor. If your system was centralized,
this would require an upgrade or replacement of the processor.
Because the Ockam system is modular, the upgrade might only require a
software change or at most an interface swap-out.

The
T2 can take the compass input, or it can be attached to the T1
processor or an 032 heading interface. |
