Customizing the Display of Data
Echograms
Echograms are a representation of what is detected by the sensors with the acoustic signals.
Adding a Range Marker
You can set a range marker at a given depth, for example if you need to ensure that your trawl net stays at this depth. It is called a Variable Range Marker (VRM).

Display Configuration

- 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.

- Managing Windows

  - Echograms
    Echograms are a representation of what is detected by the sensors with the acoustic signals.
    - Displaying an Echogram
      You can display an echogram view on a page.
    - Echogram Display Settings
      You can apply different display settings to the echogram.
    - About the Echogram Display
    - Changing the Echogram Colors
      You can change the default colors of the echogram. The ability to configure the color palettes is interesting to highlight specific things, for example to clearly distinguish the sea bottom from fish targets.
    - Displaying the View from Surface to Seabed
      You can choose to display the echogram beginning from the water surface instead of the default view from the sensor position. Depending on the type of fishery, this is useful to see the trawl descent from the sea surface to the seabed.
    - Displaying Echograms of Seine Sensors
      You can display an echogram image of the contents of a seine purse when using a Seine sensor with side-looking option.
    - Displaying the Bottom Line
      You can display lines on an echogram to mark the bottom of the trawl and the beginning of the seabed.
    - Changing the Distance from the Door Sounder to the Bottom
      You can change the distance at which the Door Sounder echogram begins.
    - Adding a Range Marker
      You can set a range marker at a given depth, for example if you need to ensure that your trawl net stays at this depth. It is called a Variable Range Marker (VRM).
  - 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.
  - 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.

Adding a Range Marker

You can set a range marker at a given depth, for example if you need to ensure that your trawl net stays at this depth. It is called a Variable Range Marker (VRM).

Procedure

On the echogram, click , then select Set VRM.
Use the arrows above and below the numbers to set a value.
Click OK.
The range marker is displayed on the echogram.
To remove the range marker:
1. On the echogram, click > Set VRM.
2. From the dialog box that appears, select Remove Marker.
