Sensor Source for the System

Normally the sensor source of a system is a single workstation to which all the sensors are connected. All
workstations share the navigation sensors. The workstation selected as a sensor source is connected to all sensors.
The workstations that can be used as sensor source are shown in the Sensor source list box in the Sensors dialog
box.
Typically, the following kinds of installations for connecting sensors to the system are used:
•
One workstation to which all the sensors are connected and the others have only one DGPS connected
(minimum system configuration that fulfil IMO back-up arrangement for the ECDIS).
•
Multiple workstations to which all the sensors are connected (fully redundant workstations)
Consult with the installer to know the installation method.
Note: If you have a fully redundant system where all the sensors are connected to all workstations, it is possible to
have the same information available no matter which workstation is selected as the sensor source. If there is any
difference in installation parameters due to different combination of sensors connected, the information available
may vary when changing the sensor source. It is highly recommended that you change sensor source only when it is
required (for example when you have some failure in communications, when hardware fails, etc.) and also to change
the sensor source only when it is safe for navigation to do so. (Change of sensor source will take some time during
which the system is not fully operational.)
To change sensor source, do the following:
1. On the workstation for which you want to set sensor
source, put the cursor below the Lost TGT alarm
indication, confirm that Initial Settings is shown in
the mouse functions area then push the right mouse
button.
2. Check Sensor source then select sensor source from
the list box.
Communication program is started at the workstation
specified as the sensor source responsible for receiving
and transmitting data from/to sensors. The workstation
selected as sensor source is also indicated at the top of
the Sensors dialog box.
