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.
- Seine Explorer Specific Settings
  You need to set these settings for a Seine Explorer sensor.
  - Sounding Modes
    The sensor can send pings according to three different sounding modes.
  - Configuring the Uplink, Up (Side) and Down Settings
    You can configure different settings for uplink, down and up (side) soundings.
  - About Time Variable Gain
    TVG (Time Variable Gain) is a method that compensate signal loss in the water. Basically, the aim is to have targets or sea bottom displayed in the same color on the echogram, whatever the distance from the sensor.
- Configuring Seine Sensor Telegrams
  If you have a Seine sensor with depth and other options, you need to configure the telegrams it transmits. This does not apply to Seine Explorer.
- 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.

Sounding Modes

The sensor can send pings according to three different sounding modes.

Down 1


	Sensor sends pings towards down direction (1) only. You can control the distance with the seabed. Pings are sent quicker than with the other modes, so more data is received, which enables a better horizontal resolution. This mode is recommended for better quality echogram images.

Down 1 + Up


	Sensor sends pings towards down (1) and side (2) directions. With the down sounding, you can control the distance with the seabed. If applicable, with the side-looking (2) sounding (called up sounding in Mosa2), you can see schools of fish inside the net when the purse seine is deployed and going down. Fewer pings are sent because they are distributed between the 2 directions. As a result, data arrives slower to the receiver and echograms are of lesser quality.

Down 1 + Down 2


	Sensor sends 2 consecutive pings towards down direction (1 and 2). This mode is useful if you need to send two different pings towards the down direction. For example, sending one short and one long ping, or sending one low frequency and one higher frequency ping. Like down + up mode, fewer pings are sent because they are distributed between the two different down soundings. As a result, data arrives slower to the receiver and echograms are of lesser quality.
