Read this section to know how data are displayed on Scala2 and how to change their display.
Customizing the Display of Data
3D Views
You can display 3D views of different elements from the system, for example the trawl doors or trawl speed sensors.
Using the MultiTrawl View
You can display data from A2S door spread sensors on a 3D view of the trawls and doors.

Display Configuration
Read this section to know how data are displayed on Scala2 and how to change their display.
- Control Panels
- Customization Panels
  The customization panels contain customization options for the data.
- Receiver Data
- Using the Virtual Charger Room
  You can display the fleet of sensors in Scala2 Virtual Charger Room, when sensors are connected to the Dock or trawling.
- Creating Data Pages
- Managing Windows
- Customizing the Display of Data
  - Echograms
    Echograms are a representation of what is detected by the sensors with the acoustic signals.
  - Zooming on Timestamp and Distance Scale
    In echograms and history plots, you can zoom in and out on the distance scale and timestamp and move them along.
  - Sensor Numerical Data
    Data such pitch and roll, temperature, depth can be displayed in dials, gauges, history plots or text format.
  - 3D Views
    You can display 3D views of different elements from the system, for example the trawl doors or trawl speed sensors.
    - Using the MultiTrawl View
      You can display data from A2S door spread sensors on a 3D view of the trawls and doors.
      - Displaying the MultiTrawl View
      - Display Options
        You can change the display of the MultiTrawl using customization panels. Right-click the view to open them.
      - Understanding the MultiTrawl View
    - Using the MultiDepth View
      You can display a 3D view showing the trawl gear and the echogram images received from a Door Sounder and Door Explorer.
    - Changing the Number of Trawls
      You need to remove specific clumps when reducing the number of trawls in water.
    - Displaying the Trident View
      Trident sensors have a dedicated 3D view, showing the echogram beams, the sounding range, the depth and roll values of the sensor.
    - Displaying Trawl Door 3D View
      You can display a 3D view of the trawl doors and clump. This way, you can see the movements of the doors and clump.
    - Displaying Trawl Speed 3D View
      You can display a 3D view of the trawl speed sensor to see the positioning of the trawl and the across and along water speeds. You can use this view instead of the dial display, as this is more intuitive.
    - Displaying Vessel System 3D View
      You can display a 3D overview of the vessel system if you have the Scala Full version. To know if you have the 3D enabled, check in Menu > About Scala.
  - Displaying the Chart View
    You can display the location and trajectory of the trawl behind the vessel if you receive GPS data and have door positioning sensors.
  - Displaying a Position Marker
    You can place a marker on plots and echograms to display the GPS position at a given time on the timestamp.
- Setting an Alarm on Incoming Data
  You can be alerted by an alarm when data received have a given value.
- Changing the Default Units
  You can change the default units of data displayed in Scala2.
- Recording and Replaying Data
  Data received by Scala2 can be replayed with ScalaReplay2 application.

Understanding the MultiTrawl View

Warp lengths, received from a winch control system using NMEA sentences.
Total spread distance.
Spread distances between doors and clumps (or between doors for a single trawl).
3D representation of the position of the doors and clump. Alignment is correct when the doors are inside their outline, clumps are framed in green and axis is green.
Track of the trawl doors and clumps. Timescale is on both sides of the trawls. Timescale can show the current time or the time that has elapsed since the trawl was put in water. In this example, the elapsed time is displayed.

Examples of data received


	When a door or clump is out of alignment, it is displayed in red. The distance from the alignment axis is displayed above.


	In this case, the current spread distance is inferior to the nominal spread distance that was set. Doors are shown out of their expected position and axis is in red.


	In this case, the current spread distance is superior to the nominal spread distance. One of the clump is out of alignment.


	In this case, both clumps are out of alignment.

Important: If you do not receive warp lengths, Scala2 is not able to show the correct position of the clumps. By default, Scala2 will display the clumps in a static position out of the alignment axis, closer to the vessel.
