Sonar 3D-15 FAQ

Below are some frequently asked questions about the Sonar 3D-15. Click on a question in the table of content to the right or simply scroll down to read the FAQ's.

1. What is the maximum depth rating of the Sonar 3D-15?

The Sonar 3D-15 is rated for depths up to 300 m, ensuring reliable performance in a wide range of underwater environments.

We recommend using a power supply capable of delivering 60 W peak (surge) at 10–30 V. For optimal performance, a 20 V or higher supply is preferred.

3. Does the Sonar 3D-15 have a thermal shutdown mechanism?

Yes. The Sonar 3D-15 includes an internal thermal shutdown to prevent damage to its electronics. You will receive a warning in both the GUI and the API if the internal temperature reaches 55 °C, indicating that the unit will shut down the acoustic at 60 °C if it continues to heat up. This will cause you to loose the sonar image.

Recommended action:
- Once you see the overheat warning (55 °C), check that the Sonar is in water or cooled in any other way.
- If the temperature reaches 70 °C, the Sonar 3D-15 will shut down to prevent permanent damage and not restart before it reaches 65 °C again, and it must reach 55 °C before you will get the sonar image back.

4. What are the default network settings of the Sonar 3D-15?

By default, the Sonar 3D-15 uses DHCP (Dynamic Host Configuration Protocol). This means it attempts to get an IP address automatically from a DHCP server on your network.

However, the Sonar 3D-15 is always accessible via its fallback IP 192.168.194.96, even if no DHCP server is present. To use the fallback IP, configure your computer's network interface to an IP address in the 192.168.194.x range (e.g., 192.168.194.90) with a netmask of 255.255.255.0.

Can I disable DHCP and set a static IP?

Yes, you can disable DHCP in the config settings in the GUI and specify a custom static IP address. This is helpful if you need a fixed IP in your networking environment.

5. Is any software installation required to operate the Sonar 3D-15?

No, there is no software installation needed. Once connected and powered on, you can access the Sonar 3D-15’s built-in GUI through a standard web browser. This allows you to operate and configure the sonar without installing any additional software.

What if I need custom integration?

For advanced integrations, you can use the Sonar 3D-15’s API to develop custom solutions. This requires some programming knowledge but enables control and automation of the Sonar 3D-15’s functionality from your custom system.

6. The performance is not as expected?

If the performance is not as expected and you can not find a solution in this documentation, please crete a diagnostic log with you Sonar 3D-15 and submit a support ticket with the Sonar 3D diagnostic log file attached.
