Verifying the communication with the course
gyro
In order to operate correctly, the SU90 requires input from a course gyro. The current
heading is shown on the top bar if you have enabled this in the
Display Options
dialog
box. The communication with the sensor is tested.
Prerequisites
This procedure assumes that:
• The sensor is connected to the SU90. It is switched on and in normal operation.
• The interface port is set up with the correct communication parameters.
• You are familiar with NMEA and other relevant datagram formats.
• You know how to set up the parameters for serial and local area network (LAN)
communication.
• The vessel is berthed or at sea.
• All relevant vessel drawings, installation reports and/or measurement results are
available.
• The SU90 system is turned on and operates normally.
Neither tools nor instruments are required.
Context
Note
The input from a course gyro is essential for SU90 operation. Without the input from a
course gyro, the SU90 will not be able to present correct navigational information.This
lack of compensation will prevent the SU90 from providing correct echo information.
In most cases a suitable course gyro is already installed on the vessel. A global
positioning system (GPS) with a compatible output format can also be used.
The properties of each of the available communication ports are defined on the
I/O Setup
page. The
Sensor Installation
page allows your SU90 to communicate with external
sensors and systems. To make sure that the information from the "most reliable" sensors
are used by the SU90, use the
Sensor Configuration
page to define a datagram priorities.
The communication parameters defined for
NMEA 0183
