System Configuration and Display
Learn how to configure the receiver to be able to receive and display Door Explorer data.
- Adding the Sensor to the Receiver
  You need to add the sensors to the receiver in order to display their data on Scala2.
- Configuring the System with the Positioning Option
  If the sensors have the positioning option, you need to configure the system in order to receive the trawl position and display it in Scala2.
- Configuring Data Display on Scala2
  - Displaying Trawl Door 3D View
    You can display a 3D view of the trawl doors and clump(s). This way, you can see the movements of the doors and clump.
  - Displaying Door Explorer Echograms
  - Using the MultiDepth View on Scala2
    You can display a 3D view showing the trawl gear and the echogram images received from the Door Explorer sensors.
    - Displaying the MultiDepth View
    - Display Options
      You can change the display of the MultiDepth view using a setting panel. Click the arrow on the right side of the view to show the display options.
  - Using the MultiTrawl View on Scala2
    You can display a global 3D view of the trawl gear.
  - Displaying Door Positioning Data
    If the door sensors have the positioning option, you can display views showing the trawl position.
- Changing the Number of Trawls
  You need to remove specific clumps when reducing the number of trawls in water.
- Replaying Data Recorded on a Memory Card
  In Scala2, you can replay data that has been recorded in high definition on the sensor memory card.

Displaying the MultiDepth View

Before you begin

Go to Menu

> Settings > Trawl, then 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.

Procedure

Click Menu > Customize and enter the password eureka.
Open the Customize panel on the left side of the screen, then drag MultiDepth to a page.

Results

The view is displayed. You can see the depth (distance from the sensor to the sea surface) and height (distance from the sensor to the seabed) of the sensors above the 3D view. Click the arrow on the right side of the view to show the display options.

To zoom on a specific area of the echogram, deactivate the Customize mode, then right-click the echogram and move the mouse while you hold down the right button.
