HD-C16L
Fully verified
Manufacturer class: LED display asynchronous control system
LED multimedia playback card that integrates a sending card, a receiving card and a playback terminal, so no computer is needed as the playback terminal. Its onboard receiver with 12 HUB75E interfaces connects directly to the screen, and a Gigabit output network port can cascade HD-R series receiving cards for a maximum control range of 650,000 pixels.

Source note
Compiled from the official English specification "LED display asynchronous control system HD-C16L" V2.0 (Dec. 12th, 2024). The document states two capacities: 650,000 pixels as the maximum control range (reached with cascaded receiving cards on the Gigabit output port; maximum width 8192, maximum height 1920 pixels) and 200,000 pixels, maximum width 2048 pixels, for the C16L alone on its 12 onboard HUB75E interfaces. The catalog capacity fields hold the 650,000-pixel maximum control range; the onboard figure is a specification row. A second RJ45 Gigabit output port (copy display) is optional and is not counted. The document lists video container formats, not codecs, and does not mention any video input. 4G, GPS, RS232/RS485, sensors and voice broadcasting are options. The document does not name a product series and gives no height for the board.
