Sensor Configuration
Learn how to configure the sensor settings.
- Connecting the Sensor to Mosa2
  To configure the sensor, you need to connect it to Mosa2 using a wireless communication or using the Configuration Cable.
- Spread Sensor Specific Settings
  You need to set these settings for Spread sensors.
  - Defining the Trawl Geometry
    You need to define for the Master Spread Sensor the type of trawl that you are using.
  - Defining the Starboard and Clump Sensor Type
    You need to define the type of Starboard and Clump (if applicable) sensors that are installed.
  - Configuring Spread Sensor Telegrams
    You need to configure telegrams sent by the Master, Starboard and Clump (if applicable) sensors.
  - Configuring Spread Sensor Positioning Settings
    You need to configure the settings of the signal sending positioning data.
  - Configuring the Spread Sounding Channel
    For XL bottles produced before S/N 3636606 (see sticker on the end cap), you need to configure correctly the up and down channels.
  - Calibrating the Pitch and Roll
    You need to calibrate the pitch and roll of the sensors when they are placed in the sensor pockets.
- Slant Range Specific Settings
  You need to set these settings for Slant Range sensors.
- Configuring the Uplink Power
  You can increase the uplink power of the sensor to increase the power of the signal transmitted. It is useful if you have interferences or if the sensor is far from the vessel.
- Testing Measures
  You can test the measures taken by the sensor (e.g. battery level, temperature, depth) to check that there are no faults.
- Exporting Sensor Configuration Settings for Record Keeping
  You can export in a *.txt file all the settings configured for the sensor (such as ping length, frequency, range, TVG...).
- Exporting Sensor Configuration Settings for the Receiver
  You can export on an XML file the sensor settings that you configured on Mosa2. You can afterward use this file when adding the sensor to a receiver.

Configuring Spread Sensor Positioning Settings

You need to configure the settings of the signal sending positioning data.

About this task

The signal sending positioning data is called a chirp signal. It allows to calculate the bearing to the trawl.

Default chirp settings are already set, change them only if necessary.

Note: Only Master and Starboard sensors can send positioning data.

Important: Master and Starboard Spread sensors must have the same chirp settings.

Important: If you have other NBTE sensors (Trawl Explorer, Catch Explorer, Bottom Explorer…) we recommend to allow enough distance (min. 200 Hz) between their frequencies and the chirp bandwidth.

Procedure

Click the tab Chirp.
If you use a Clump sensor with FIRM173, you need to deactivate the chirp signal from this sensor: from Activate Chirp Mode, select No.
For Master and Starboard sensors, from Chirp Frequency, enter the center frequency of the signal sent by the sensor.
From Chirp Length, enter the length (milliseconds) of the signal sent by the sensor.
From Chirp Bandwidth, enter a frequency bandwidth of the signal sent by the sensor. We do not recommend to enter a frequency bandwidth lower than 10 kHz.
For example, if the center frequency is 50 kHz and the bandwidth is 10 kHz, the signal will cover the frequency 45 kHz to 55 kHz.
Click Apply and make sure there is a green check mark .
