Configuring Data Display on Scala2

You can display on pages in Scala2 measurements taken by the sensors, such as the spread distance or the pitch and roll of the doors. You can also use the chart or 3D view to display the position of the trawl.

About this task

Sensor measurements are displayed in the control panels, under Mx. Data title should be:
  • Spread Master / Spread Slave / Spread Clump for Spread sensors.
  • Slant Range for Slant Range sensors.

The title is followed by the node where the sensor was placed when added to the system.

  4. To change the door or clump model:
    1. From the top left corner, click Menu > Settings.
    2. Click the Trawl tab and select the models of doors and clump from the lists, using left and right arrows.
  5. You can also change the viewing angle: looking from the trawl toward the vessel (front), or from the vessel toward the trawl (back).
  6. To change the view angle of the door, right-click the 3D view and choose:
    • Horizontal Camera to see the doors from the front: Or back:
    • Vertical Camera to see the doors from above.
    • Free Camera to adjust the viewing angle yourself, by clicking and dragging the 3D doors.
  7. To display or hide the ground, right-click the 3D view and select or not Display Ground. You should leave the ground displayed, in order to see if the doors are touching it.
  8. To save the changes you made:
    1. To rename the page, right-click the name of the page and click Rename.
    2. To save the page, right-click the name of the page and click Save Changes.
  9. Deactivate the Customize mode when you have finished customizing pages: click Menu > Customize again.

Spread Sensor: Displaying Single Trawl Spread

Procedure

  1. From the top left corner of the screen, click Menu > Customize and enter the password eureka.
  2. Open the control panels and from the Mx tab, click + hold distance data from spread sensors such as Distance to Stbd from a Spread Master and drag it to the page display.
  3. In Choose new Gauge Type, select History Plot.
  4. Right-click the history plot and select Vertical.
    The history plot becomes vertical. You can see the distance between the port and starboard door.
  5. If you have a firmware version 08.03 and above, you can display the battery level on the plot. Right-click the title of the plot and click Battery Indicator.

What to do next

Deactivate the Customize mode when you have finished customizing pages: click Menu > Customize again.

Spread Sensor: Displaying Twin Trawl Spread

Before you begin

You need to have twin trawls and Spread sensors with dual or triple distance option.

Procedure

  1. From the top left corner of the screen, click Menu > Customize and enter the password eureka.
  2. If you have twin trawls with 2 measured distances, drag to the page the Spread Master Distance to Stbd, then drag Distance to Clump above the plot of the distance to starboard. Right-click the plot and click Vertical.
    Distances between the port door and starboard door and between the port door and clump are displayed.
  3. If you have twin trawls with 3 measured distances, open the Customize panel and go to the Mx tab.
    • Click + drag a Twin Trawl Spread Plot to the page. You can know if the clump is centered when the yellow dashed line is above the red and green lines.
    • Or click + drag a Twin trawl Spread Diagram to only display the diagram.
    Now you can see the distances between:
    • port door and starboard door,
    • port door and clump,
    • clump and starboard door.
    Note: Right-click the plot and click Single Trawl Spread Plot if you need to switch to single trawl.

What to do next

Deactivate the Customize mode when you have finished customizing pages: click Menu > Customize again.

Displaying the Chart View

Before you begin

  • You must be in Customize mode to do this task.

You must have:

  • Incoming GPS data and heading data.
  • Spread or Slant Range sensors with bearing measurement
  • Warp lengths or Slant Range sensors giving distance to vessel

Procedure

  1. Open the customization panel, then go to Geographic.
  2. Click + drag Chart to the page.
  3. Drop it in a yellow area.
    The chart view is displayed. The heading of the vessel, the port (red) and starboard (green) door paths appear by default.
  4. Click the arrow on the right side of the view to show the display options.
    Trouble: If the view looks empty it might be because the view is not centered on the vessel. Open the setting menu and click View > Center on Ownship or Center on Ownship and Trawl.

Displaying the Vessel 3D Overview

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.

Before you begin

You must be in Customize mode to do this task.

You need to have incoming data from:
  • GPS (position, heading)
  • Sensors with positioning
  • Warp lengths or Slant Range sensors giving distance to vessel

Procedure

  1. Open the customization panel, then go to Geographic.
  2. Click + drag the 3D Overview to the page.
    A 3D view of the vessel and trawl is displayed.If you have twin trawls, you can see it on the 3D view as well. Make sure you have configured twin trawls in the receiver settings.
  3. To change the vessel 3D model, from the upper left corner of the screen click Menu > Settings and click the Ownship tab.
  4. To change the view, you can use the numeric keypad: press the keys 0 to 9 to change the viewing angle.
  5. Right-click the 3D view and click Center on Ownship to focus on the vessel or Center on Trawl to focus on the trawl.

What to do next

Deactivate the Customize mode when you have finished customizing pages: click Menu > Customize again.

Doors Positioning Data

You can display data related to the position of the doors.

Before you begin

Note: Minimum data required to display Doors Positioning are GPS positioning, depth, door spread distance, port and starboard door bearings. However, we strongly recommend to receive warp lengths from a winch control system. Without it, the accuracy of the positioning will be reduced.

Procedure

In the control panels, go to the trawl data. In Scala2, the name of the panel depends on the trawl gear setup. The panel can display Single Trawl, Twin Trawl, Triple Trawl or Quad Trawl.
Tip: This panel displays the door horizontal distance (1) and slant distance (2) to the boat:

Bearing Angles

Procedure

You can see the relative (R) bearing angles of the doors. Angles are relative to the stern, unlike Scala version 01.06.34 and below, where angles were relative to the heading of the vessel. Angles toward port side are negative and angles toward starboard side are positive. See About Trawl Positioning for drawings.
