Step 3: Connect the Keyboard and Power Supply

Connect the OSD keyboard cable to the designated header on the controller board.
Connect a 12Vdc, 2A or greater power adapter to the DC input jack on the board.

Caution: The controller board must be insulated. Do not place it directly on metal surfaces or conductors to prevent short circuits and potential damage.

Step 4: Connect Video and Audio Inputs

Connect your video source (e.g., computer, Raspberry Pi) to either the DVI or VGA input port on the controller board.
If audio output is desired, connect speakers to the audio output connector.

Step 5: Power On

Once all connections are secure, plug in the power adapter to an electrical outlet. The LCD panel should power on and display the input signal.

Maintenance

To ensure the longevity and proper functioning of your controller board, observe the following maintenance guidelines:

Keep the board in a clean, dry environment, free from dust and moisture.
Avoid exposing the board to extreme temperatures or direct sunlight.
Ensure proper ventilation around the board during operation.
Do not attempt to modify the board or its components, as this may void any potential warranty and cause damage.
Always disconnect power before making or changing any connections.

Troubleshooting

If you encounter issues with your VSDISPLAY controller board, refer to the following common troubleshooting steps:

No Signal Displayed:
- Verify that the LVDS cable is securely connected to both the controller board and the LCD panel.
- Ensure the power adapter is correctly connected and providing 12Vdc, 2A or more.
- Check that your video source is active and properly connected to either the DVI or VGA input.
- Use the OSD menu to manually select the correct input source (DVI or VGA).
- Confirm your LCD panel is listed as compatible with this board.
OSD Menu Navigation Issues:
- If button labels on the keypad do not seem to match their function, experiment with the buttons to understand their actual behavior (e.g., 'Menu' might select, 'Auto' might exit, 'Left' might move down, 'Right' might move up).
Screen Flickering or Incorrect Colors:
- Ensure the LVDS cable is fully seated and not damaged.
- Check the power supply for stability; an insufficient power supply can cause display issues.
- Adjust OSD settings like contrast and brightness.
Board Not Powering On:
- Confirm the power adapter is functional and meets the 12Vdc, 2A+ requirement.
- Ensure the board is not short-circuited by being placed on a conductive surface.
