Setup Instructions

1. Power Connection

Connect a 12V/24V DC power supply to the designated power input port on the board. Ensure correct polarity to prevent damage to the device.

2. Storage Media

Insert a formatted USB drive or TF memory card containing your media files into the respective USB host port or TF card slot. The board supports up to 2000GB capacity.

3. Video Output

Connect an HDMI cable from the board's HDMI output port to your display device (e.g., monitor, TV, projector). Ensure the display is set to the correct HDMI input source.

4. Audio Output

For analog audio, connect appropriate cables to the AVout port. Digital audio is transmitted via the HDMI connection.

5. Control Interface

Depending on your application, connect the remote control receiver, integrate with a single-chip IO system using the provided pins, or establish serial communication via the TTL/RS485 ports.

Operating Instructions

1. Basic Playback

Once powered on, the board will either automatically begin playing media or enter a standby mode, depending on the configured settings. Ensure your media files are in supported formats (e.g., MP4, AVI, MP3, JPG).

2. Control Modes

Remote Control

Use the provided infrared remote control to navigate menus, select files, and manage playback functions such as play, pause, stop, next track, and previous track.

Serial Communication (TTL/RS485)

For advanced and automated control, send commands via the serial port. The protocol specifications are 8 data bits, 1 stop bit, no parity, and a baud rate of 9600bps. Refer to the detailed serial communication protocol documentation for a complete list of commands and their usage.

Single-Chip IO Control

The 4 IO ports can be utilized to trigger specific video segments. This allows for point-to-point designated playback of up to 10 distinct video segments, ideal for interactive installations.

3. Playback Modes

The FJD-8200HD7 board supports various playback modes to suit different applications:

• Auto Play: Media playback starts automatically upon device power-up.
• Memory Play: Resumes playback from the last stopped position after power cycling.
• Sequence Play: Plays media files in numerical order as they appear in the playlist.
• Loop Play: Continuously repeats the entire playlist of media files.
• Single Play: Plays a selected file once, then enters a black screen standby state.
• Random Play: Plays files in a non-sequential, random order.
• Single Loop: Continuously repeats a single selected media file.

Maintenance

To ensure optimal performance and longevity of your FJD-8200HD7 board, adhere to the following maintenance guidelines:

• Cleaning: Gently clean the board with a soft, dry, anti-static cloth. Avoid using liquids, solvents, or abrasive cleaners, which can damage components.
• Environmental Conditions: Operate and store the board in a dry, well-ventilated area. Protect it from extreme temperatures, high humidity, dust, and direct sunlight.
• Handling: Always handle the board by its edges to prevent touching sensitive electronic components. Avoid static discharge by grounding yourself before handling.
• Firmware Updates: Periodically check the manufacturer's official website for any available firmware updates. Updates can improve performance, add new features, or resolve known issues.

Troubleshooting

No Power

Symptom: The board does not power on, and no indicator lights are active.

Solution:

• Verify that the power supply is correctly connected and providing the specified 12V/24V DC.
• Check the power adapter and cable for any visible damage or loose connections.
• Ensure the power outlet is functional by testing it with another device.

No Video Output

Symptom: The connected display shows no signal, a black screen, or an error message.

Solution:
