- Support for both 12V and 24V LED strips (input voltage must match LED strip voltage).
2. Setup Guide
2.1. Physical Installation
Ensure all power is disconnected before making any electrical connections. The controller requires a DC 7.5-24V power input and provides 5 output channels for RGB, Warm White, and Cool White LED strips.

Follow the wiring diagram below for correct connections. The controller uses a common anode connection mode.
- V+ (Input): Connect to the positive (+) terminal of your DC power supply (7.5-24V).
- V- (Input): Connect to the negative (-) terminal of your DC power supply.
- V+ (Output): Connect to the common positive (+) terminal of your LED strip.
- R (Output): Connect to the Red channel of your RGB LED strip.
- G (Output): Connect to the Green channel of your RGB LED strip.
- B (Output): Connect to the Blue channel of your RGB LED strip.
- WW (Output): Connect to the Warm White channel of your LED strip.
- CW (Output): Connect to the Cool White channel of your LED strip.

Important: The input voltage from your power supply must match the voltage requirements of your LED strip (e.g., 12V power supply for 12V LED strip).
2.2. App Installation
Download the free control application from your device's app store:
- For iOS devices (iPhone, iPad, iPod Touch): Search for the app on the Apple App Store.
- For Android devices: Search for the app on Google Play.
Once installed, launch the application.
2.3. Network Connection
The controller can be connected in two ways:
- Direct Connection: The controller creates its own Wi-Fi access point. Connect your smartphone directly to this network (SSID typically starts with "LEDnet" or similar, check the controller label if available). This method is suitable for controlling a single unit or when a local Wi-Fi network is not available.
- Local Wi-Fi Network Connection: For controlling multiple units or integrating into your home network, connect the controller to your existing Wi-Fi router.
- Open the app and navigate to the network settings.
- Select your local Wi-Fi network and enter the password.
- Once connected, your smartphone can control the controller via your home Wi-Fi network. This allows for simultaneous control of multiple LD686 controllers.

3. Operation
Once connected, the mobile application provides a comprehensive interface for controlling your LED strips.
3.1. Color and Brightness Control
The app features a color wheel for selecting any desired color for RGB LED strips. You can also adjust the brightness level from 0% to 100% for all channels (RGB, WW, CW).

3.2. Warm White (WW) and Cool White (CW) Control
For LED strips with dedicated Warm White and Cool White channels, the app allows independent control of their brightness and intensity.

3.3. Music Synchronization
The app includes a music activation feature. Play music on your mobile device, and the LED lights will change in rhythm with the music, creating dynamic lighting effects.
3.4. Custom Colors and Patterns
You can create and save custom color presets and lighting patterns directly within the application. This allows for personalized lighting scenes that can be recalled at any time.

4. Maintenance
The XCSOURCE LD686 WiFi Controller is designed for reliable operation with minimal maintenance. To ensure longevity and proper function:
- Cleaning: Gently wipe the controller's exterior with a dry, soft cloth. Avoid using harsh chemicals or abrasive cleaners.
- Environment: Keep the controller in a dry environment, away from direct sunlight, extreme temperatures, and high humidity.
- Connections: Periodically check all wiring connections to ensure they are secure and free from corrosion.
- Firmware: Check the app store periodically for updates to the control application, which may include performance improvements or new features.
5. Troubleshooting
If you encounter issues with your XCSOURCE LD686 WiFi Controller, refer to the following common problems and solutions:
- LED Strip Not Lighting Up:
- Verify that the power supply is correctly connected and providing the correct voltage (12V or 24V) matching your LED strip.
- Check all wiring connections between the power supply, controller, and LED strip for looseness or incorrect polarity.
- Ensure the LED strip itself is functional.
- Cannot Connect to Controller Wi-Fi:
- Ensure the controller is powered on.
- If connecting directly, check your phone's Wi-Fi settings for the controller's network (e.g., "LEDnet").
- If connecting via a local Wi-Fi network, ensure the controller is within range of your router and has been correctly configured with the network's SSID and password.
- Try restarting the controller by disconnecting and reconnecting its power.
- App Not Responding or Crashing:
- Close and restart the application.
- Ensure your smartphone's operating system is up to date.
- Check for updates to the control application in your device's app store.
- If the issue persists, try reinstalling the app.
- Incorrect Colors or Functions:
- Verify that the RGB, WW, and CW wires are connected to the correct terminals on the controller.
- Ensure the LED strip type selected in the app (if applicable) matches your physical LED strip.
If these steps do not resolve the issue, please contact XCSOURCE customer support for further assistance.
