Synchronous, Asynchronous and Spliced Displays
Asynchronous mode uses the internal media source. Synchronous mode uses HDMI input. For synchronous full-screen scaling, the specification requires a video-source width from 64 to 2048 pixels and supports downscaling only, not upscaling. HDMI input/output cascading supports multi-screen splicing.
Video decoding capacity is separate from the 1.3-million-pixel LED load. The feature summary refers to H.264/H.265 4K at 60 Hz, while the detailed decoding table lists H.264 at 30 fps and H.265/HEVC at 60 fps. Use the format-specific table when preparing media; confirm any H.264 60 fps requirement before deployment.
Publishing, Wi-Fi and Optional Modules
USB Type A supports program playback and firmware upgrades. Supported USB drives use FAT32 or NTFS, range from 2 GB to 128 GB, and require individual files larger than 0 KB and smaller than 4 GB.
Wi-Fi AP and Sta are switchable modes. In AP mode, connect the user device to the AD20 hotspot. In Sta mode, connect the user device and AD20 to the same router. When several network methods are available, priority is wired Ethernet, Wi-Fi, then 4G.
The 4G module is not included by default. Multi-screen synchronized playback supports NTP, GPS with the specified 4G module, or RF with the specified RF module. Third-party Android application installation is not supported.
Audio Connection Note
Internal audio uses 48 kHz; external audio supports 32, 44.1 and 48 kHz. Audio through a multifunction card must use 48 kHz. The PDF feature list describes one stereo output, while its connector table labels two AUDIO OUT connectors; confirm the supplied board’s audio layout if this is important to your installation.

Frequently Asked Questions
What is the difference between AD20 synchronous and asynchronous modes?
Synchronous mode displays the HDMI input source. Asynchronous mode plays the internal media source. The AD20 provides a dedicated mode-switch key.
How should I connect to AD20 over Wi-Fi?
In AP mode, connect your device to the AD20 hotspot using the details on its label. In Sta mode, the AD20 and your device should connect to the same router. The specification describes switching between these modes.
Can AD20 drive a 4096 × 4096 LED display?
No. Maximum width and height are each 4096 pixels, but total LED load is limited to 1.3 million pixels. Both dimension limits cannot be combined into a 4096 × 4096 load.
Can AD20 splice several displays through HDMI?
Yes. HDMI input and output cascading supports multi-screen splicing. HDMI output is specified up to 1080p at 60 Hz; synchronous full-screen scaling supports downscaling only for source widths from 64 to 2048 pixels.
Does AD20 include 4G connectivity as standard?
The card supports a 4G module, but the module is not included by default. GPS timing requires the specified 4G module; RF timing requires the specified RF module.
