Speed Explorer Specific Settings
Speed Explorer sensor has specific settings that need to be configured.
Configuring Measurement Sending Sequence and True Mode
If you use the True Mode display for echograms in Scala2, you need to select a specific sequence of measurements (e.g. temperature, pitch, roll...) sent by the uplink to the receiver.

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.
- Speed Explorer Specific Settings
  Speed Explorer sensor has specific settings that need to be configured.
  - Sounding Modes
    The sensor can send pings according to three different sounding modes.
  - Configuring the Uplink, Up and Down Settings
    You can configure different settings for uplink, down and up 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 Measurement Sending Sequence and True Mode
    If you use the True Mode display for echograms in Scala2, you need to select a specific sequence of measurements (e.g. temperature, pitch, roll...) sent by the uplink to the receiver.
- Configuring Flow Sensor Telegrams
  You need to define channels and telegrams that the sensor uses to transmit data to the receiver. These settings are for Trawl Speed, Grid and Symmetry sensors.
- Checking Speed Measures with EM Log Tester
  You need to check the speed measures of all speed sensors with an EM Log tester.
- 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 Measurement Sending Sequence and True Mode

If you use the True Mode display for echograms in Scala2, you need to select a specific sequence of measurements (e.g. temperature, pitch, roll...) sent by the uplink to the receiver.

Before you begin

The sensor is connected to Mosa2.

Procedure

From Mosa2, click Menu > Expert and enter the password copernic.
Click the tab Trawl Explorer.
From Option True Mode, select a sequence from True Mode Option.
- Select Config1 (default): this is the more appropriate sequence for a Speed Explorer.
- Or select Config3 if you use the True Mode display on echograms in Scala2.
Click Apply.
Below is an example of echograms without True Mode (top) and with True Mode (bottom). When the option is activated, you see the area between the sea surface and the seabed. This way, you can see the trawl descent. See Scala2 user guide for more information.
