5.2. Initial Network Configuration

Upon first power-up, the device typically boots in Access Point (AP) mode, allowing direct connection for initial configuration.

1. Connect to AP: On your computer or mobile device, search for available WiFi networks. The device will broadcast an SSID (e.g., "waveshare_XXXX"). Connect to this network.
2. Приступ Web Интерфејс: Отвори а web browser and navigate to the default IP address (refer to the product documentation or quick start guide for the specific IP, commonly 192.168.1.1).
3. Пријава: Enter the default username and password (usually "admin" for both, or as specified in documentation).
4. Конфигуришите подешавања мреже: У оквиру web interface, configure the desired operating mode (STA, AP+STA, etc.), WiFi credentials (SSID, password for STA mode), and Ethernet settings if applicable.
5. Сачувај и поново покрени: Save your settings and reboot the device for changes to take effect.

6. Радни режими

The converter supports various operating modes to suit different application requirements:

6.1. Wireless Networking Modes

• Режим приступне тачке (AP): The device acts as a WiFi hotspot, allowing other WiFi-enabled devices to connect to it directly. This is often the default mode for initial setup.
• STA Mode (Station): The device connects to an existing WiFi network (e.g., your home or industrial WiFi router) as a client.
• AP+STA Mode: The device functions as both an Access Point and a Station simultaneously, allowing local devices to connect to it while it also connects to an external WiFi network.
