Connections to the instrument
You can connect your instrument:
Directly to the compass transducer as a stand-alone master
instrument. When connected in this manner, the instrument must be
connected to a suitable power source using the 1 m (3 ft) power
cable provided.
As part of a SeaTalk system either as a repeater or, with a transducer
also connected as a system master. To connect to SeaTalk, you will
need an additional SeaTalk Interconnection Kit (Part No. E25028).
When connected in this manner, power can be provided from the
SeaTalk bus (e.g. from the autopilot).
Provided there is no other Fluxgate Compass already connected to
SeaTalk, you can connect the instrument to both the compass
transducer and SeaTalk. When thus connected, the instrument will be
the master compass instrument for the SeaTalk system.
If it is necessary to fit spade connectors to the transducer cable, do so as
shown in the following illustration. Prepare the cable, as at (a), and fit
the spade connectors as at (b). When fitting each spade connector,
ensure that wire strands do not extend beyond the rear of the spade
connector insulation.
