Context
NoteThe input from a speed log is essential for CS90 operation. Without the input from a speed log, the CS90 will neither be able to present correct navigational information, nor compensate for vessel movements. This lack of compensation will prevent the CS90 from providing correct echo information.
In most cases a suitable sensor 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:
