Best suited for

  • Driving a cabinet or module group of up to 128 × 1,024 pixels with a single card.
  • Permanent installations that need temperature / voltage monitoring.

Key features (manufacturer)

  • Single card loads up to 192×1024 pixels (PWM chips); 128×1024 with normal chips, 162×1024 with Shixin chips
  • 16 groups of parallel RGB data or 32 groups of serial RGB data, expandable to 128 serial groups
  • 8 integrated HUB75 interfaces (J1~J8)
  • Supports up to 1/128 scan
  • 8bit video source input, 240Hz frame rate
  • Pixel-to-pixel calibration in brightness and chromaticity (8bit)
  • Loop redundancy and firmware program redundancy with readback
  • Dual RJ45 Gigabit network ports, input/output auto-identified

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 196,608 px for modules with PWM driver chips.
