System Configuration and Display
Learn how to configure the receiver to be able to receive and display door sensor data.
Adding Sensors to the Receiver
You need to add the sensors to the receiver in order to display their data on Scala2.
Adding the Sensor Manually
You can add the sensor to the receiver from Scala2, by entering the same settings as the ones in Mosa2.
Configuring Sensor Settings

System Configuration and Display
Learn how to configure the receiver to be able to receive and display door sensor data.
- Configuring the Hydrophones
  You need to configure the hydrophones to correctly receive signals from the sensors.
- Adding Sensors to the Receiver
  You need to add the sensors to the receiver in order to display their data on Scala2.
  - Adding the Sensor with a Configuration File
    You can add the sensor to the receiver with a configuration file that contains the sensor settings you configured on Mosa2.
  - Adding the Sensor Manually
    You can add the sensor to the receiver from Scala2, by entering the same settings as the ones in Mosa2.
    - Adding Sensors to the Receiver
    - Configuring Sensor Settings
  - Configuring the Positioning Settings
    You need to configure the positioning settings on the system web page (receiver page on Scala2.
  - Calculations for 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 angles with the following calculations.
- Adding Data from External Devices
  You need to add to Scala2: warp lengths (Spread sensors only), GPS coordinates and heading data received from devices such as winch control systems or GPS compass.
- Configuring Trawl Settings
  You need to configure trawl settings to display the trawl on the chart and vessel 3D overview.
- 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.
- Displaying Trawl Positioning from Scala2 on Olex
  You can export trawl positioning data coming from Scala2 to Olex software.
- Displaying Trawl Positioning from Scala2 on MaxSea Version 12
  You can export trawl positioning data coming from Scala2 to MaxSea v12 application.
- Displaying Trawl Positioning from Scala2 on MaxSea TimeZero
  You can export trawl positioning data coming from Scala2 to MaxSea TimeZero application.
- Displaying Trawl Positioning from Scala2 on SeapiX
  You can export trawl positioning data coming from Scala2 to SeapiX application.
- Displaying Bathymetric Data from GEBCO Database
  You can display bathymetric data coming from GEBCO database on the 3D overview of the vessel.
- Receiving Warp Lengths from Scantrol
  You can output warp length data from Scantrol iSYM Trawl Control application to Scala2 software.

Configuring Sensor Settings

Important: Make sure the settings you enter here are the same as in Mosa2.

Spread Sensors


1	Sensor name displayed in Scala2 and its features.
2	This setting helps detecting the signal of the sensor among other sensor or echosounder signals. Change only if you have issues receiving data. Detection and 2D: default value. This setting helps distinguishing the sensor signals when there are a lot of interferences (e.g. echosounders). It selects the correct signals according to very selective criteria. Detection: If you do not receive data, it may be because the Detection and 2D setting is too selective with the signal. Detection is less selective and allows more signals to be received. Detection for Seiner: no need for this sensor
3	Low: if the signal of the sensor is high = the trawl is close to the vessel (SNR min. 18 dB). Medium: Default setting. Compromise between the two other settings (SNR min. 12 dB). High: if the signal of the sensor is low = the trawl is far from the vessel (SNR min. 6 dB).
4	Master and clump sensors only: enter the same frequencies and telegrams as those entered in Mosa2.
5	Enter the same frequencies as those entered in Mosa2 for each option.
6	Enter the same telegrams as those entered in Mosa2 for each option.
7	Click Configure to change filters applied on incoming data.
8	Enter the positioning parameters you entered in Mosa for Chirp.
9	Click Configure to change filters applied on positioning data.

Click Apply when you have finished.

Slant Range Sensors


1	Sensor name displayed in Scala2 and its features.
2	This setting helps detecting the signal of the sensor among other sensor or echosounder signals. Change default setting only if you have issues receiving data. Choose between 0-2 only if no interferences on the vessel (not recommended). 3 is default setting. Choose between 4-6 if you have issues receiving data. It allows you to receive more data, but be aware they might be wrong data.
3	This setting also helps detecting the sensor signal. Leave default setting at Synchro 1.
4	Enter the frequency you entered in Mosa2 in Pinger Boat Code/Channel Code.
5	Enter the frequency you entered in Mosa2 in Ping Down Frequency.
6	Enter the pinger delay you entered in Mosa2 in Pinger Delay for Response.
7	Click Configure to change filters applied on incoming data.
8	Enter the positioning parameters you entered in Mosa for Chirp.
