Configuring the Sensor Settings

Seine Explorer

Important: Make sure the settings you enter here are the same as in Mosa2.
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 same frequency as the one entered for the uplink frequency in Mosa2.
5

Select the range of Down sounding from the drop-down menu.

Select Up-Sounding if the sounding mode of the sensor is Down 1 + Up. Then, select the range of Up (side-looking) sounding.

Select Double Down if the sounding mode is Down 1 + Down 2. Then, select the range of Down 2 sounding.
6 Click Configure to change filters applied on incoming data. Filters are particularly useful to reduce interferences on the echogram data.
Tip: Please refer to Scala2 user guide for more information about the filters.
7 Helps you detecting targets on the echogram. Corresponds to Channel minimum TS in Mosa2.
8 Do not change this setting.
Click Apply when you have finished.

Seine sensors with depth and other options

Note: The picture below shows a Seine sensor with height, depth and temperature options.
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: Use if you do not receive data or data is wrong with two above settings and if depth is less than 100 m.
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 Enter the same frequencies as those entered in Mosa2 for each option in Boat Code/Channel Codes.
5 Enter the same telegrams as those entered in Mosa2 for each option.

Results

The sensor is added to the system. You should see incoming data from the control panels, in Sensors Data. You can now configure the display of incoming data in Scala2.
