Huidu A5 Controller Box – Anleitung zur Synchronisierungsfunktion

The Huidu A5 is a dual mode: synchronous and asynchronous player box, synchronous operation covers two types of scenarios:

（1）HDMI External Video Synchronization Real time synchronization of  PC or set top box display on a single unit.

（2）Synchronization of A5 units over a LAN multi screen synchronized display or playback.

一. Real time HDMI video synchronization synchronizing an external video source on a single unit:

（1）Hardware Wiring:

①Computer or Player  or Set top Box HDMI Output to Huidu A5 HDMI IN.

②A5 Ethernet port connects to R712 receiving card to drive the LED screen.

③For audio synchronization synchronize via the HDMI audio source, or output audio to speakers using the A5 of 3.5mm audio port.

（2）HDSet Software Setup Steps：

①Connect the A5 via Ethernet or Wi-Fi use HDSet to search for and select the device.

②Top menu Settings to Playback Mode.

③Playback mode selection Synchronous First, Prioritizes the live HDMI input, automatically switches to offline content if the HDMI connection is lost.

④Resolution Matching align the HDMI input resolution as closely as possible with the screen’s resolution width and height, and enable image scaling.

⑤Click OK to send the parameters, the screen will synchronize in real time with the HDMI video source image.

 

二. LAN-based program synchronization for multiple HD A5 units multiple screens playing the same program in sync:

For applications such as light pole displays, chain store advertising screens, and multi screen synchronized playback, each A5 unit independently drives a single screen, ensuring perfect visual synchronization.

①All A5 models are standardized as HD A5 and share the same firmware version.

②All LED screen specifications including resolution, refresh rate, and module parameters are identical.

③All devices play the exact same playlist, program duration, and special effects.

④All connections should be made to the same LAN switch direct cable connection, cross routing is prohibited.

（1）Hardware Networking：

①Connect the Ethernet port of each A5 unit to a Gigabit switch, they are on the same LAN.

②No manual IP configuration required, the A5 automatically identifies device IDs on the LAN.

（1）HDSet Synchronization Parameter Configuration：

①Select all A5 devices to Settings to Time Settings.

②Time correction selection Synchronize the computer synchronize computer time.

③Upon issuance, the system time of all devices is synchronized at the millisecond level.

（2）Enable multi machine synchronization group：

①Menu Settings to  Sync settings.

②The software automatically scans the local area network for all online A5 devices.

③Select all devices requiring synchronization and set the Sync Mode to NTP Network Synchronization for all of them.

④Click Sync Time to synchronize the clocks, then click Set to save the synchronization group.

三. HDMI Cascading Video Wall Synchronization Not supported by A5, explanation of alternative solutions:

The HD A5 lacks an HDMI output port for cascading, so it cannot be used to daisy chain HDMI connections to form a large, unified screen like the A6L, 
multi screen splicing can only be achieved by..

①Video processor distributing HDMI signals to multiple A5 units external source synchronization.

②Multi A5 LAN synchronization, with each screen displaying a specific section of the image.

四. Troubleshooting Common Synchronization Issues:

（1）Image desynchronization and misalignment:

①Verify that all screen resolutions and refresh rate settings are identical.

②Resynchronize the computer time and issue synchronization group parameters.

Replace Gigabit Ethernet cables and switches, and avoid using wireless WiFi for synchronized networking.

（2）HDMI Syncs but No Image：

①Switch the playback mode to Synchronous First.

②Confirm that the HDMI signal source output is functioning correctly and that the cable meets the HDMI 2.0 standard or higher.

（3）Playback speeds vary across multiple devices：

①Upgrade the firmware of all devices to the same version.

②Do not add variable dynamic special effects to the program, standardize the video frame rate to 25, 30, or 60 fps.
