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 Options
You can change the display of the MultiTrawl using customization panels. Right-click the view to open them.

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.

Display Options

You can change the display of the MultiTrawl using customization panels. Right-click the view to open them.

Controls


	Trawl Setup: select Auto to automatically detect the number of trawls or select manually the type of trawl gear in use. If you change the trawl gear, change this setting accordingly. Door Spread: Current value: current total spread distance. Nominal value: total spread distance you want to have. If the value of the current distance becomes larger or smaller than the nominal value, the alignment axis appears in red. Tolerance: tolerance threshold between the current and nominal values. Reset nominal: if the current spread distance is correct, click to make this distance the nominal value. Track History: zoom in and out of the time scale of the trawl tracks.

Important: To have correct door spread values displayed on Scala2, you need to be careful when you reduce the number of trawls.See Changing the Number of Trawls.

Settings

Camera: change the viewing angle of the 3D view.

Clump Spreads:


Show distances: real values of spread between two door sensors.
Show projections: calculated values of linear spread between door sensors. These values have a yellow dot instead of a green dot.

Note: Spread distances and projection distances should be the same. If not, it means the doors or clumps are not aligned.

Time Ticks: select Show dates to show the current time on the timescale or Show delays to show the time that has elapsed since the trawl was put in water.

Warp Labels: display the warp lengths received from a winch control system or the slant distance received from a Duplex sensor.
Door Gauges and Clump Gauges:
- Show roll gauges and Show pitch gauges: displays angular gauges to help with door pitch and roll monitoring.

Models


	You can change the model of trawl doors or clumps. Click the arrows to select the model. The 3D view will change accordingly.
