  • Page 22: About The Virtual Water-Switch Option

    Note: When you change settings such as the uplink power or sounding range, it affects the battery consumption and remaining lifetime. The battery information will update after the sensor has been switched on and operating for 10 minutes. About the Virtual Water-Switch Option Mosa2 has a virtual water-switch option that changes the conditions under which the sensor is running.

  • Page 23: Diagnostic Information

    • When the virtual water-switch is activated: the sensor runs when the depth is more than 2 meters and the water-switch is in contact with water. We recommend to activate it to prevent the sensor from running outside water. For example, if the sensor is hauled on deck and stays inside the net, the water- switch remains wet and keeps emitting.

  • Page 24: Configuring The Trawl Node

    • The charger plug displays a warning icon: When the alarm appears, take the sensor out of water immediately and contact Marport support. Warning: In case of water ingress in the product, do not charge it: battery may vent or rupture, causing product or physical damage.

    You can create a table with a list of frequencies and complete it when you add sensors. Frequencies and intervals The diagrams below show the bandwidth of the different types of Marport sensors and intervals you must respect when adding other sensors. Figure 1. PRP sensors (e.g. Catch sensor, Trawl Speed, Spread sensor...) Example: If the frequency of the sensor is 40kHz, there should be no sensors between 39.9 and 40.1kHz.
  • Page 74 Figure 3. NBTE sensors (e.g. Speed Explorer, Trawl Explorer, Catch Explorer, Catch Navigator, Door Sounder) Example: If the frequency of the sensor is 40kHz, there should be no sensors between 39.8kHz and 40.6kHz. Figure 4. HDTE narrow band mode Example: If the frequency of the sensor is 40kHz, there should be no sensors between 39.8kHz and 41kHz.
  • Page 75 Examples of frequency allocations • We recommend to allocate frequencies between 34 and 56 kHz for wideband hydrophones and between 41 kHz and 44 kHz for narrowband hydrophones. • Echosounders are usually placed around 38 kHz, make sure to allow enough distance with them.
