Learn how to configure the receiver and display the sensor data in Scala2 application.
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 the Positioning Settings
Configure the positioning settings on the system web page to correctly receive the positioning data from the sensors.

System Configuration and Display
Learn how to configure the receiver and display the sensor data in Scala2 application.
- 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 the Positioning Settings
    Configure the positioning settings on the system web page to correctly receive the positioning data from the sensors.
  - Calculations for the Positioning System
    When configuring the positioning system on the system web page (Scala2 receiver page), you must consider the position of the hydrophones. When they are misaligned, you can calculate their misalignment angle with the following calculations.
  - Configuring Trawl Settings
    You need to configure trawl settings to display the trawl on the chart and vessel 3D overview.
  - Adding Data from External Devices
    You need to add to Scala2: warp lengths, GPS coordinates and heading data received from devices such as winch control systems or GPS compass.
  - Receiving Warp Lengths from Scantrol
    You can output warp length data from Scantrol iSYM Trawl Control application to Scala2 software.
- Configuring Data Display on Scala2
- Changing the Number of Trawls
  You need to remove specific clumps when reducing the number of trawls in water.
- Replaying Data Recorded on a SD Card
  You can replay in Scala2 data that have been recorded in high definition on the SD card .

Configuring the Positioning Settings

Configure the positioning settings on the system web page to correctly receive the positioning data from the sensors.

Before you begin

You have added the sensors to the receiver.

Tip: A spreadsheet is available on the Useful Resources page of Marport support website to help you complete this page.

Procedure

From the left side of the screen where the system is displayed, click Positioning.

The positioning configuration page appears.
In Baseline, enter the baseline distance and the misalignment angle.

Note: The baseline is very important to have accurate positions of the doors.

Important: If the starboard hydrophone is placed further aft, add a negative (-) sign before the angle.
In Inputs, enter the port and starboard hydrophones, according to the hydrophone configuration.

Note: On M4 and M6 systems, the receiving hydrophones must be both connected to a hydrophone input between H1, H2 and H3 or both between H4, H5 and H6.
Click Apply.
