Huidu HD-C16C asynchronous LED controller
The Huidu HD-C16C combines stored multimedia playback, sending and receiving functions for an LED display. Its 10 onboard HUB75E interfaces connect to modules, while the Gigabit output supports a compatible HD-R receiving-card arrangement. Wi-Fi and LedArt provide mobile program management; Ethernet and USB offer additional update methods.

Choosing and setting up a C16C
Check module driver IC, scan mode, screen width and height, and the direct or receiving-card wiring plan. Video decoding resolution is separate from LED output loading. Use the PC input port for configuration or router access and the Gigabit output for receiving cards; match the cable connections to the interface diagram.
For remote installations, specify whether Wi-Fi/Ethernet access is available or an optional 4G module is required. Sensor and GPS connectors require compatible external devices. Confirm the relay wiring and load requirements before integrating power control.

Frequently asked questions
What software is used with the HD-C16C?
HDPlayer sets screen parameters and edits and sends programs on a PC. LedArt supports mobile control; the documented cloud platform supports Internet management.
Does the HD-C16C need a computer connected during playback?
It is an asynchronous controller with onboard storage. Publish programs through Ethernet, Wi-Fi or USB for stored playback; confirm the required content and screen configuration during setup.
How many HUB75E ports does the C16C have?
The C16C specification lists 10 onboard HUB75E ports. The two 50-pin HUB connections described for C16 should not be used as the C16C wiring reference.
Is 4G included as standard?
No. The 4G networking module is an optional configuration. Wi-Fi, Ethernet and USB are documented communication methods.
What is the maximum pixel load?
The V0.1 document contains conflicting capacity figures: 524,288 in the overview and 120,000 (384 × 320) in the features. Provide the exact screen dimensions and board revision for confirmation; the listed maximum width and height cannot be multiplied to claim a larger capacity.
