Operation menu

The Operation menu allows you to control the operating mode, the recording functionality, and how the MF90 system transmits audio pulses ("ping") into the water.

Select the Operation icon.

The icon is located under the Main menu. Select the icon one more time to close the menu.

Note:

Immediately after you have turned on the MF90 system, the Operation icon is flashing. The icon is flashing to indicate that even if the MF90 system is turned on, "pinging" is disabled. When the MF90 system is turned on, Tx Power is by default set to Off. This is a safety precaution to prevent inadvertent transmissions when the vessel is in dry dock.

Only brief descriptions are provided.

For detailed information about each function, page or dialog box, refer to the Functions and dialog boxes chapter in this publication.

Tip:

If you do not need to use the menu system, you can hide it. This allows more space for the echo presentation.

Use the Menu on the top bar to hide or show the menu. When the menu system is hidden, it appears temporarily on the left or right-hand side of the screen if you move the cursor to that position.

Functions and dialog boxes

Operation

The Operation function controls the operating mode of the MF90 system. You can set it to Normal, Replay or Inactive.

Transmission Mode

Transmission Mode lets you to control how often the MF90 system shall transmit acoustic energy (ping) into the water.

Tx Power

Use Tx Power to increase or decrease the output power. The output power is selected from predefined steps.

Record RAW

Record RAW allows you to record the unprocessed echo data received by the transducer. You can save the data to the hard disk, or onto an external storage device. The data files can be played back on the MF90 system. You can keep the recorded files for future reference, training purposes and calibration.

Record Processed

The Record Processed function allows you to record the processed echo data received by the transducer. Which processing to apply is controlled by the settings on the Processed Data to File page. Processed Data to File is located in the Output dialog box.

Output

The purpose of the Output dialog box is to collect all functionality related to data output in one easily accessible location. The dialog box is organised in pages grouping parameters for different parts of the application.

The following pages are provided:

File Setup: A useful function of the MF90 system is it ability to record echo data. To retrieve the data files you need to know where they are, and which file names that have been used. The purpose of File Setup is to define the file and folder properties for the data files that you are recording. You can select the disk and folder for the files, the maximum file size, and a prefix for the file names.
I/O Setup: To communicate with peripheral devices the Processor Unit offers several serial and/or Ethernet (LAN) ports. The number of communication ports depends on how your Processor Unit is set up and configured. For each port, you can set up the communication parameters, and monitor the data flow.
Processed Data to File: The MF90 system can export several types of processed data file formats. Use Processed Data to File to define which processed data formats to save, and where to place the files. This page is located in the Output dialog box.
Marker output: Use the Output Marker page to export target markers to a communication port.
Relay Output: The MF90 system allows you to export the same sensor data that was originally imported. This functionality permits you to reuse the sensor data on other systems. Use the Relay Output functionality to set up and control the sensor data export.
Screen Recording: The Screen Recording function allows you to record and save the echo presentation as a video file. Each screen recording you make is saved in .mp4 format on the Processor Unit hard disk. Use the Screen Recording page to define where the video files are saved.
Screen Captures File Location: While using the MF90 system you may wish to make a screen capture to save an instantaneous copy of the current presentation. Use Screen Capture File Location to define where to save your screen captures.
