Use this option to select the source of the heading data. If using
a sonar which contains an internal heading and compass device
or if the compass is connected to the Aux port of the sonar
select Internal/Aux Compass. If the compass device has been
connected through a COM port on the SCU or PC, or if a USBL
system is in use then select Ship/USBL Compass. If the sonar
is mounted to an ROV and both the ROV and support vessel
have a compass it is possible to switch to the ROV compass by
selecting Sub/ROV Compass.
Note
There must be active sonar data, as well as position and heading data, for the
position co-ordinates to be reported.
Note
The compass and pitch/roll display are never displayed side-by-side as shown
here, their position is at the top/bottom right of the screen by default but can be
changed using the Compass Settings dialog.
