Configuring the Sensor Settings

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

Catch Sensor

Note: The options (depth, temperature, etc.) vary according to the firmware installed.
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 Enter the same frequencies as those entered in Mosa2 in Boat Code/Channel Codes.
5 Enter the same telegrams as those entered in Mosa2 for each option.
6
Click Configure to change filters applied on incoming data. Filters are particularly useful to reduce interferences on the echogram data.
Tip: Catch telegram has a specific filter called Debounced: you can choose to display status as full when receiver has received 2, 3 or 4 "full" signals from the sensor.
Click Apply when you have finished.

PI Catch Sensor

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 for Seiner: no need for this sensor

  • 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 frequency as the one entered for the uplink frequency in Mosa2.
5

Enter the interval at which signals are sent. They must be the same as in Mosa2. The update of data is quicker when Fast is set, but this reduces the battery life.

  • Fast: full every 5 sec. / Empty every 5.5 sec.
  • Normal: full every 32 sec. / Empty every 3 sec.
  • Slow: full every 123 sec. / Empty every 126 sec.

Click Configure to change filters applied on incoming data.

Catch Explorer

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.
  • 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 Range of the down sounding. Corresponds to Sounding Range in Mosa2.

Catch Explorer V2 only: select Double down if using Down 1 + Down 2 sounding mode.
6 Click Configure to change filters applied on incoming data. Filters are particularly useful to reduce interferences on the echogram data.
Tip: Catch telegram has a specific filter called Debounced: you can choose to display status as full when receiver has received 2, 3 or 4 "full" signals from the sensor.
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.

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.
