Verifying the communication with speed log
In order to operate correctly, the SC90 requires input from a speed log. The current speed
is shown in the
Status
parameter dialog box. The communication with the sensor is tested.
Prerequisites
This procedure assumes that:
• The sensor is connected to the SC90. 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 SC90 is turned on, and it is working normally.
Neither tools nor instruments are required.
Context
In order to operate correctly, the SC90 requires input from a speed log. Without the
input from a speed log, the SC90 will neither be able to present correct navigational
information, nor compensate for vessel movements. This lack of compensation will
prevent the SC90 from providing correct echo information. In most cases a suitable
sensor is already installed on the vessel. A global positioning system (GPS) with a fitting
output format can also be used.
The communication parameters defined for
