Verifying the communication with the course gyro
In order to operate correctly, the CS90 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 CS90. 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 CS90 is turned on, and it is working normally.
Neither tools nor instruments are required.
Context
Note
The input from a course gyro is essential for CS90 operation. Without the input from a course gyro, the CS90 will not be able to present correct navigational information.This lack of compensation will prevent the CS90 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 CS90 to communicate with external sensors and systems. To make sure that the information from the "most reliable" sensors are used by the CS90, use the Sensor Configuration page to define a datagram priorities.
The communication parameters defined for NMEA 0183 are:
•  Baud Rate: 4800 b/s
•  Data Bits: 8
•  ParityNone
•  Stop Bits: 1
Procedure
1 Open the Setup menu.
2 On the Setup menu, select Installation.

Observe that the Installation dialog box opens. This dialog box contains a number of pages selected from the menu on the left side.
3 On the left side of the Installation dialog box, select Sensor Installation.
a Select the relevant sensor in the Installed Sensors list.
b Make sure that the correct installation parameters are used for the sensor.
4 On the left side of the Installation dialog box, select Sensor Configuration.
a Select the relevant sensor in the Sensor list.
b Make sure that the correct parameters are used for sensor configuration.
5 Close the Installation dialog box without making any changes.
6 Observe the top bar.
7 Make sure that the information from the sensor is displayed.
If necessary, enable the read-out in the Display Options dialog box.
8 If possible, use another instrument to verify that the information provided by the CS90 is correct.
9 Fill in the result tables.
