Trawl page
When you use a trawl, the EK80 can draw the upper and lower trawl lines in the echogram. In order to this, the EK80 needs to know the relevant trawl parameters. If your trawl system is connected to the EK80, these parameters are automatically available. If the trawl system is not connected, the Trawl options allow you to define the parameters manually.
Prerequisites
Several of the pages in the Installation dialog box are not available when your EK80 system is set to Replay mode.
How to open
This page is located in the Installation dialog box. To open, select it on the Setup menu.
Description
A Simrad ITI (Integrated Trawl Instrumentation) system can be connected to the EK80 system. Communication with the ITI system is based on both NMEA and proprietary telegrams, and all necessary parameters are automatically
defined. The information can be used to draw the upper and/or lower trawl lines in the echogram.
If another trawl or catch monitoring system is used, and this system does not provide the trawl opening and/or trawl distance
automatically, the values must be entered manually.
When you record raw data, all the data received from the trawl system are saved to the file.
Tip
To connect and set up the actual interface, use the Sensor Installation page. The Sensor Installation page is located in the Installation dialog box.
To set up the communication parameters between the trawl or catch monitoring system and the EK80 system, use the I/O Setup page. The I/O Setup page is located in the Installation and Output dialog boxes.
When you work in the Installation dialog box, you must always select Apply to save the changes made on a page. You must do this before you continue working on a different page.
