Huidu HD‑R712 LED Receiving Card 12×HUB75E Dual‑Mode Controller

Huidu HD‑R712. It is a professional dual‑mode LED display receiving card designed for both synchronous and asynchronous control systems, eliminating the need for an adapter board. Equipped with 12×standard HUB75E interfaces onboard, supporting 24 groups of RGB parallel data for strong stability and large loading capacity. Max control range reaches 262,144 pixels (512×512); recommended loading is 128×1024 pixels for conventional IC modules and 256×1024 pixels for PWM IC modules. It features 2×Gigabit Ethernet ports for fast data transmission with a communication distance up to 80 meters via Cat5e/Cat6 cables. Supports scan modes from static to 1/128 scan, compatible with all common IC and most PWM IC modules. It works with dual‑mode players, asynchronous/synchronous sending cards, and VP series video processors. Functions include multi‑card cascade with arbitrary sequencing, 256–65536 grayscale levels, smart setup, and integrated screen testing. Widely used in indoor/outdoor commercial advertising, retail LED screens, stadiums, transportation hubs, and public information displays.
