+The I/O Interface provides a simple means of connection to Water Linked products. It provides power and connection interfaces for Water Linked sensors during development. 
+
+It utilizes the Molex Micro-Fit 3.0 power connector (Part number: 436500228). Female connectors are listed under [Mates with Part(s)](https://www.molex.com/en-us/products/part-detail/436500228#mates-with-use-with).

 ## 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.
+By default, the Sonar 3D-15 uses **DHCP** to request an address. If no DHCP server answers, it is always accessible on the fallback IP `192.168.194.96`. For a step-by-step guide to using the fallback IP, mDNS, or setting a static IP in the GUI, see [Sonar 3D-15 Networking](sonar-3d-15-networking.md).

 ## 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?
