Signal wave form of Compass transducer see § 9 Wind Transducer
The signal wave form of the compass transducer is similar to that of the Wind
transducer.
The two outputs are of the type open collector, i.e. there is a demand of a pull-up
resistor to get out an output signal.
Recommended value: 5 - 10 kΩ
NEXUS Network
Compass Transducer connect to the NX2 Server or NX2 Compass Data
instrument will give output of 5 deviated compass headings per second on the
NEXUS Network.
The NX2 Server will output NMEA 0183 compass data from 1 to max. 4 times per
second (selectable).
The Server is operated by use of the NX2 Multi Control, Multi Center or NX2
Remote Control instrument and will perform an Automatic deviation and an
Automatic check. Adjustment of the A-fault and local magnetic variation can also
be done. The values are stored in 10 year minimum EEprom memory without any
need of battery backup.
