Package Contents
- 1 x FJD-8200HD8 Playback Board
- 1 x Remote Control
Setup
Refer to the diagram below for port identification and connection points.

- Power Connection: Connect a DC 12V-25V power supply to the 'Power Input Socket' (DC-005 5.5*2.1mm). Ensure the power supply provides sufficient current (at least 2A, or >2.5A if using a mobile hard disk).
- Video Output: Connect an HDMI cable from the 'HDMI HD Output' port to your display device. For composite video and audio, use the 'Audio/Video Output Interface' (3.5mm jack).
- Storage: Insert a U disk into the 'U Disk Interface' or a TF memory card into the 'TF Memory Card' slot.
- Remote Control: Ensure the 'Infrared Remote Control Receiver' is unobstructed for proper remote operation.
- Advanced Control (Optional):
- Serial Communication: Connect your serial device to the 'RS485 Interface' or the 'Serial, Matrix, Button Trigger Interface' (TTL pins).
- Button Trigger: Connect external buttons to the 'Serial, Matrix, Button Trigger Interface' for point-to-point video playback. Refer to the pinout diagram on the back of the board for specific connections (PREV, NEXT, STOP, ENT, MUTE, etc.).

Operating Instructions
- Power On: Once power is connected, the board will initiate.
- Playback Modes: The board supports various playback modes, which can be configured as needed:
- Automatic Playback: Configured to automatically start playing media upon power-up.
- Memory Playback: Resumes playback from where it last stopped.
- Sequential Playback: Plays files in numerical order.
- Loop Playback: Continuously repeats the entire playlist.
- Single Playback: Plays a single file. In this mode, after playback, the screen enters a black standby state, awaiting new instructions. A busy state output is provided.
- Random Playback: Plays files in a shuffled order.
- Single Loop: Continuously repeats a single file.
- File Management: Organize your media files on the U disk, mobile hard disk, or memory card in numerical order for predictable sequential playback. The board supports arbitrary file updates without disrupting the order.
- Remote Control: Use the provided remote control to navigate menus, select files, control playback (play, pause, stop, next, previous), and adjust volume.
- Button Control: For specific applications, external buttons connected to the trigger interface can be used for point-to-point designated playback of up to 10 videos. After a designated video plays, the board can enter black screen standby or play a small video.
- Serial Communication Control: Utilize TTL/RS485 serial commands for advanced control and integration with other systems. The communication format is 8 data bits, 1 stop bit, no parity, and a baud rate of 9600bps.
Maintenance
- Cleaning: Gently wipe the board with a dry, soft cloth. Avoid using liquid cleaners or solvents.
- Storage: Store the board in a dry, dust-free environment when not in use.
- Handling: Handle the board by its edges to avoid touching components, especially when powered.
- Power: Always disconnect power before making any physical connections or disconnections.
Troubleshooting
- No Power:
- Ensure the power adapter is correctly connected to the DC-005 5.5*2.1mm socket.
- Verify the power supply voltage is within the 12V-25V range and provides sufficient current.
- No Video Output:
- Check the HDMI cable connection to both the board and the display.
- Ensure the display is set to the correct input source.
- If using CVBS, verify the connection and display input.
- Files Not Playing:
- Confirm that the U disk, mobile hard disk, or memory card is properly inserted.
- Check that the media files are in supported formats (e.g., H.264, H.265) and resolutions (up to 1920x1080@45fps).
- Ensure the storage device is not corrupted.
- Remote Control Not Responding:
- Check the batteries in the remote control.
- Ensure there are no obstructions between the remote control and the infrared receiver on the board.
- Button Control Issues:
- Verify the wiring of external buttons to the 'Serial, Matrix, Button Trigger Interface' according to the pinout.
- Ensure the button logic is correctly configured for point-to-point playback.
User Tips
- Power Supply: When using a mobile hard disk, it is crucial to use a power supply that can deliver at least 2.5A to ensure stable operation.
- File Naming: For predictable sequential playback, name your video files with a clear numerical order (e.g., 01.mp4, 02.mp4, etc.).
- Custom Applications: The serial communication and button trigger interfaces offer extensive customization possibilities for integration into complex systems like escape rooms or interactive displays.
