Huidu HD-R708 LEDディスプレイ受信カード
The HD-R708 receives display data through Gigabit Ethernet and connects LED modules through 8 integrated HUB75E interfaces. It supports conventional driver chips and mainstream PWM chips, with different recommended loading ranges for the two chip types.
Module Configuration and Multi-card Setup
The card supports static modules and scan modes up to 1/128, data-group exchange and offset settings. Multiple receiving cards can be cascaded and arranged in the required order. Intelligent settings, screen-routing configuration and an integrated screen test function help with setup and display checks.
