Configuring Sensor Settings

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 as those entered in Mosa2 in Clump and Starboard Boat Code/Channel Codes.
5	For each option, enter the same frequencies as those entered in Mosa2 in Boat Code/Channel Codes.
6	For each option, enter the same telegrams as those entered in Mosa2.
7	Click Configure to change filters applied on incoming data.

Marport PI compatible Spread Sensors

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.

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 frequency as the one entered in Mosa2 in PI Starboard Channel or PI Clump Channel, if applicable (exact frequency is visible from the Information page).
5	Enter the interval at which signals are sent. They must be the same as in Mosa2.
6	Click Configure to change filters applied on incoming data.

Door Sounder Sensor

Door Sounder with target strength calibration

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	Range of the down sounding. Select and complete Double Down if using Down 1 + Down 2 sounding mode.
6	Click Configure to change filters applied on incoming data. Tip: Please refer to Scala2 user guide for more information about the filters.
7	Do not change this setting.
8	Do not change this setting.

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.
