10.4 Course gyro
Introduction
The heading can come from two different sensor types. Tick off for
the type which will be connected.
• Course gyro
• (D)GPS
Note that the heading information from a GPS is generally too
inconsistent to provide a stable sonar presentation.
Refer to the selected heading source in the following text.
Course gyro
The Processor Unit can read the heading information from a
RS-232 serial line. If only a 3-phase synchro or stepper signal is
available, an optional gyro interface unit must be used for
converting these signals to RS-232 serial line format.
Observe t he following procedure to test the course gyro input:
1 Access the I/O Setup menu.
2 Select Sensors in the I/O Setup menu, then Heading and
finally Gyro.
3 Observe the Sensor Config submenu appears at the bottom
of the menu field.
4 Change the settings in the Sensor Config submenu to suit
your requirements for the serial line.
5 Press Close to exit the Sensor Config menu.
6 Check that the heading readout in the Status menu
corresponds to the vessel’s course gyro.
