Click Menu > Eject Config Plug or Connect Config Plug. If ejected, the cable stays disconnected until you virtually connect to it or manually disconnect then connect it.

  • Page 19: Sounding Modes

    Trawl Explorer | V7 | Sensor Configuration 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 see fish going into the trawl. Pings are sent quicker than with the other modes, so more data is received, which enables a better horizontal resolution.

  • Page 20: Configuring The Uplink, Up And Down Settings

    Trawl Explorer | V7 | Sensor Configuration Configuring the Uplink, Up and Down Settings You can configure different settings for uplink, down and up soundings. Before you begin The sensor is connected to Mosa2. About this task Remember: Always click Apply after you change a setting and make sure there is a green check mark Procedure Click the tab Trawl Explorer.
  • Page 21 Trawl Explorer | V7 | Sensor Configuration Important: Down 1 + Down 2 sounding mode: configure Down 1 sounding in Down settings and Down 2 sounding in Up settings (Up Sounding Range, Ping Up Length, Ping Up Frequency, Up channel minimum TS, Up TVG Mode, TVG Up). 2.

  • Page 22: Target Strength

    Important: Frequency needs to be between 120-210 kHz. Important: Do not change ping frequency on a V3 sensor or it will have to be returned to a Marport sales' office for target strength calibration. Target Strength Procedure For V3 version of sensors, Down channel minimum TS and Up channel minimum TS helps you detecting targets on the echogram.
