Scala2 does not open due to error message saying Scala2 cannot be opened. Your Mac security preferences do not allow you to open applications not downloaded from the App Store.
  1. Click Apple menu > System Preferences > Security & Privacy
  2. From the lower-left corner of the Security & Privacy dialog box, click the lock icon and enter your password if you have one.
  3. In Allow apps downloaded from, select Anywhere.
  4. If you are under OS X Sierra and above, click Open Anyway
Under macOS Ventura, Scala2 takes time to open. This issue is due to the operating system of the computer, macOS Ventura. Wait for a few seconds for Scala2 to open. Do not force quit the application.
On Scala2 opening, a message appears saying that the license file is not found. The license file is not on the computer or not stored in the correct location. Scala2 needs a licence file to run correctly. It must be stored directly under Documents/Marport.
  1. Click OK to open the dialog box and select the file, if it is on the computer. The licence file will automatically be added to Documents/Marport.
  2. If you do not have a license file, contact your local Marport office to get a license file.
The license file does not correspond to the computer serial number.
  1. Go to Documents/Marport to check the *.keep file name.
  2. To know the serial number of your mac, click Apple menu > About This Mac.
  3. Compare the numbers: if the Mac serial number is 123ABC, the name of the license file will be MAC123ABC.keep.
  4. If the numbers do not correspond, contact your local Marport office to get the correct license file.
A message appears asking for access to your folders when opening Scala2. It also stops the automatic opening of the application. Under macOS Catalina, you need to give full disk access to Scala2. Go to the computer's System Preferences > Security & Privacy > Privacy > Full Disk Access, then add Scala2 and ScalaReplay2 to the list.
When starting the system, there is a black window saying failed and asking for a login. This window comes from a virtual machine software that analyzes sensors data. This program is necessary for the correct operation of the receiver.
Important: DO NOT CLOSE this window. Failed and login indications are normal and always appear. You do not need to enter anything.
  • On the top of the window, click minimize to hide it. Change the settings as explained in Automatically Opening Scala2 at Start Up to keep it hidden. This icon should always appear at the bottom of your desktop screen:

  • If you close the window, restart the computer.
  • Do not click inside the window or you will loose the mouse. If you lost the mouse, connect a keyboard and press ctrl + cmd (Apple) / ctrl + window key (Windows).
Sensor data is not displayed, LEDs are red or orange. You may have closed the virtual machine when you opened Scala2 or when you plugged in a device.
  1. Check if this icon is in the dock, at the bottom of your screen:

  2. If it is not present, restart the system.
    Important:

    A virtual machine starts automatically when starting your computer and is necessary for Scala2 functioning. The virtual machine window can appear when opening Scala2. Do not close it.

    A message is also displayed when plugging an USB device. For guidance, see: A VMware Fusion message appears when adding a new USB key.
Ethernet connection is down.
  1. Click Menu > Expert Mode and enter the password copernic.
  2. Open the control panels and go to the Mx panel. Click the menu icon next to the name of the receiver and click Configure Receiver.
  3. From the system setting page, check on the schema at the bottom is there are green checks.

  4. If there is a red cross, check that the power supply for PoE adapter is connected to the mains supply.
  5. From the system page, click Hydrophones from the panel on the left.
  6. Check the hydrophones current status. If there is no current:
    1. Check from the configuration page that the correct hydrophone type between passive and active is selected.
    2. Check that the wiring in the hydrophone junction box is correct.
A VMware Fusion message appears when adding a new USB key. This message is due to the virtual machine that is installed on your computer with Scala2. It appears when adding an external USB device.

  1. Select Remember my choice and do not ask again.
  2. Click Connect to Mac.
The size of Scala2 window is smaller than before. Scala2 window must have lost the full screen display. Double-click the top of the window to have a full screen window.
I cannot find a window I created. You may have closed the window. Click Menu > Open Window X.

The window opens.

Note: If you moved or deleted all the pages contained in a window, this window is permanently deleted.
I do not see pages I created on the top toolbar. You may have moved these pages to a new window.
  1. Check your other windows to see if your page appears in it. If you created a window and cannot find it, see the previous troubleshooting case.
  2. If you want to move your page to another window, connect in Customize mode. To move it to the window with the control panels, right-click the page name and click Move to Main Window. To move it to another window click Move to Window X.

You may have hidden this page (Customize mode only) See Hiding a Page.

  3. Drag on top of the list the network you use to have internet. It can be for example your phone WiFi, your WiFi router, a USB to Ethernet adapter...
The echogram display is interrupted, it shows black lines. There is a loss of communication between the sensor and the boat. If the acoustic signal from the sensor is not received, the last sonar data is repeated for a few seconds, then stopped. This will show black lines on the echogram.

Scantrol application do not receive speed measurements You have a system configured as a twin trawl and put only one trawl in water. Scantrol does not receive anymore speed measurements from the speed sensor.

Scala2 2.10.x and later: If the system is configured to operate on a twin trawl with one speed sensor on each trawl, but only one trawl is put in water: make sure that the speed sensor in water is the one from the first trawl, configured with a node between 10 and 13. If not, Scala2 will not send any speed measurements.
