HD-T902x2 eight-port synchronous LED sending box
The Huidu HD-T902x2 sends live DVI video to an LED screen through eight Gigabit Ethernet outputs. The V1.0 specification describes it as equivalent to four T901 sending cards and identifies Huidu R-series receiving cards for the receiving side.
Two DVI inputs, two USB-B configuration connections and two stereo inputs support system integration. The document lists up to 5.2 million pixels when the sending box is connected to a video processor, and supports multiple units for spliced displays.
Configuration, audio and power
Use HDSet to configure the screen and receiving-card parameters. Audio is routed through the network connection to a compatible multifunction card for output. The unit takes 110–220 V AC and includes an AC-to-5 V DC transformer; the internal DC figures in the document should not be confused with the mains input.

Values follow the linked HD-T902x2 V1.0 specification. The source differs in its internal DC minimum, playback-software names and audio row labels. These details require confirmation for the actual installation; the documented eight-output hardware configuration is consistent across its main sections.

Frequently asked questions
Does the HD-T902x2 have four or eight LED outputs?
The linked V1.0 specification identifies eight Gigabit Ethernet outputs in its overview, feature list, interface table and appearance description. This page follows that eight-output specification.
Does it need a video processor to reach the stated loading capacity?
The system table states a maximum of 5.2 million pixels when connected to a video processor and lists 2560 × 2048 at 60 Hz. Confirm the source timing, processor setup and receiving-card mapping for the intended screen.
Which software and receiving cards are used?
The specification identifies HDSet for configuration and Huidu R-series receiving cards. It mentions HDPlayer in the overview but HD Show in the playback-software table, so confirm the appropriate playback software for the installed system.
How does audio reach the speakers?
The feature list specifies two stereo inputs. The document explains that audio is sent through the network connection and needs a multifunction card for output. Its audio row labels are inconsistent, so confirm the required multifunction card and amplifier connections for the installation.
Can several T902x2 boxes be used together?
Yes. The specification supports multiple units for spliced displays and unified control. Plan each unit’s source feed, screen area and receiving-card connections together; the per-unit loading limits still apply.
