NETWORK COMPA SS USER MANUAL

In this configuration the COMPASS unit is set to transducer mode and will send heading
data to the other instruments. The other Network units are also transmitting data that the
COMPASS may be able to use. For example, if the COMPASS is set to Head/Lift mode
the wind angle data will cause it to switch between port and starboard tacks
automatically.
INITIAL POWER-UP
When a COMPASS unit is powered up for the first time it will automatically adjust itself to
the phase characteristics of the fluxgate sensor, so if it is to be used with a fluxgate (that
is, in transducer mode) the fluxgate should be installed and connected before applying
power. Refer to the installation guidelines at the back of this manual for advice on
optimum siting of the fluxgate. During the phase adjustment the display will show PHS
and a pair of chevrons to indicate which of the phase settings is currently being tested.
When all the phase settings have been tested the optimum one is selected and stored for
future use. The complete phase adjustment procedure takes about 20 seconds.
The same phase adjustment is also carried out immediately before a calibration swing
(see CALIBRATING THE COMPASS, page 17).
