Best suited for

  • Driving a cabinet or module group of up to 128 × 1,024 pixels with a single card.

Key features (manufacturer)

  • 12 HUB75E interfaces on board, no HUB adapter board needed
  • Maximum loading capacity 262,144 pixels (512×512)
  • Recommended loading capacity: 128×1024 pixels with conventional chips, 256×1024 pixels with PWM chips
  • Any scanning method from static to 1/128 scan
  • Two interchangeable 1 Gbps Ethernet ports
  • Works with dual-mode sending boxes, asynchronous and synchronous sending cards and VP series video processors
  • Gray scale 256~65536
  • Rated voltage DC 4.0V-5.5V, power 5W

Capacity and loading area

The card receives data over the Ethernet chain and drives the module group inside this area. The cabinet/module load cannot exceed this area or the capacity of 131,072 px.This figure is for modules with conventional driver chips; the datasheet states 262,144 px for modules with PWM driver chips.

Source note

maxLoadingPixels = 128×1024 = 131,072, the recommended loading capacity printed for conventional chips. The document also prints "Maximum loading capacity: 262,144 pixels (512*512)" without naming a chip type; that total equals the recommended PWM-chip rectangle (256*1024). Both statements are kept in specs. The document does not state the number of RGB data groups, so dataGroups is null. Dimensions are read from the dimension drawing, which prints no unit. syncPlayback/asyncPlayback are left null because they describe player modes; the control-system compatibility the document states is kept as a specs row. Not stated in this specification and kept from the earlier excerpt of the official product page (not verified against a document): dataGroups.
