3. Telîmatên Operating

3.1 Modên Lîstinê

The FJD-8200HD7 supports various playback modes:

• Lîstina Otomatîk: Configurable to start playing automatically upon power-on.
• Memory Playback: Resumes playback from where it left off.
• Sequential Playback: Dileyze files in numerical order.
• Loop Playback: Continuously repeats the playlist.
• Single Playback: Plays a single file. In this mode, after playback, the board enters a black screen standby and outputs a busy state signal.
• Lîstina Rasthatî: Dileyze files bi rêzek random.
• Single Loop Playback: Continuously repeats a single file.

Files in the playlist are arranged in numerical order, allowing for flexible updates without disrupting the sequence.

3.2 Rêbazên Kontrolê

The board can be controlled using four primary methods:

• Bişkok: Physical buttons connected to the board can trigger specific functions, including point-to-point playback of up to 10 specified video segments.
• Kontrola dûr: Use a compatible infrared remote control (not included, typically) to navigate and control playback.
• Microcontroller IO: Utilize the matrix mode of four IO ports on a microcontroller to achieve point-to-point specified playback of 10 video segments.
• Ragihandina Serîalî: Control the board via serial communication using the protocol: 8 data bits, 1 stop bit, no checksum, and a baud rate of 9600bps.

3.3 Taybetmendiyên pêşkeftî

• Seamless Playback: Supports smooth transitions between media files.
• Zivirandina ekranê: Allows for 360° rotation of the display for both horizontal and vertical screen orientations.
• File Şîfrekirin: Supports encrypted file playback to protect media content from unauthorized copying.

4. Maintenance

To ensure the longevity and optimal performance of your FJD-8200HD7 video playback board, follow these general maintenance guidelines:

• Paqij bimînin: Regularly clean the board with a soft, dry cloth to remove dust and debris. Avoid using liquids or harsh chemicals.
• Ventilasyona rast: Ensure the board is operated in a well-ventilated area to prevent overheating.
• Bi lênêrînê re mijûl bibin: Electronic components are sensitive. Avoid dropping the board or subjecting it to physical shock.
• Power Off Before Disconnecting: Always power off the device before connecting or disconnecting any cables or storage media to prevent damage.
• Embarkirinî: When not in use for extended periods, store the board in a dry, cool environment, away from direct sunlight and extreme temperatures.

5. Destpêkirin

If you encounter issues with your FJD-8200HD7 board, consider the following troubleshooting steps:

5.1 No Power/No Display

• Têkiliya Hêzê kontrol bikin: Ensure the 12V/24V power supply is correctly connected and providing adequate current (at least 1A, 2.5A for HDD).
• Kabloyan piştrast bikin: Confirm that HDMI or AV cables are securely connected to both the board and the display device.
• Display Input: Make sure your display is set to the correct input source (HDMI, AV, etc.).

5.2 Playback Issues

• Forma medyayê: Vîdyoya xwe piştrast bikin files are in a supported format (e.g., H.264 encoding) and resolution (up to 1920x1080@30fps).
• Medya hilanînê: Check if the TF card, USB drive, or portable hard drive is properly inserted/connected and formatted correctly. Try a different storage device if possible.
• File Linavketinî: Verify that the media files ne xerabûyî ne.
• Power for HDD: If using a portable hard drive, confirm your power supply provides at least 2.5A.

5.3 Control Issues

• Kontrola dûr: Check remote control batteries and ensure a clear line of sight to the infrared receiver.
• Ragihandina Serîalî: Double-check the serial communication settings (baud rate 9600bps, 8 data bits, 1 stop bit, no checksum).
