HD-T901 synchronous LED sending card
The Huidu HD-T901 takes a live DVI video signal and sends display data to compatible Huidu receiving cards through two Gigabit Ethernet ports. It is intended for computer-controlled LED screens and supports cascaded sending cards for larger configurations.
Choose a supported resolution mode
The specification gives a general loading figure of 1.3 million pixels and lists mode-specific combinations. Examples include 1280 × 1024 at 60 Hz, 1920 × 640 at 60 Hz and 2048 × 1024 at 30 Hz. The available load therefore depends on the selected resolution and refresh rate. Widths over 1,920 pixels require a video processor according to the PDF.
Use HDSet for screen configuration through USB. The document names both HDPlayer and HD Show in its playback-software descriptions, so confirm the supported playback software version for the intended setup.

Frequently asked questions
Does the T901 store and play content offline?
The T901 is a synchronous sending card. Its listed program-display method is DVI synchronous input; it is not described as a standalone stored-program player.
Which receiving cards does it work with?
The specification identifies Huidu R50X/R-series receiving cards. Confirm the exact receiving-card model, firmware and module settings for your screen.
Can I drive a screen wider than 1,920 pixels?
The PDF states that widths above 1,920 pixels require a video processor. It lists different resolution modes at 60 Hz and 30 Hz; check the specific mode rather than combining maximum width and height.
What is the USB port used for?
USB is the configuration interface. HDSet is identified for screen debugging and parameter setup; the live video signal enters through DVI.
What operating-temperature range should I use for selection?
The source PDF is inconsistent: the function table gives −20°C to +80°C, while the basic-parameters table gives −40°C to +80°C. Confirm the applicable rating for the supplied hardware before selecting it for low-temperature service.
