HD-RB6 frequently asked questions
What is the maximum HD-RB6 loading capacity?
The specification lists 131,072 pixels (256 × 512) as the maximum and recommends 98,304 pixels (256 × 384). Use the recommended value when planning, then verify the module configuration and required display performance.
Can RB6 work in synchronous and asynchronous systems?
Yes. The document lists dual-mode sending boxes, asynchronous sending cards, synchronous sending cards and VP-series video processors. Check the exact sending device and system configuration before installation.
Is RB6 suitable for transparent or film LED screens?
The card is intended for applications including transparent, light-bar and film screens. It supports up to 32 RGB parallel groups, 64 serial groups for transparent screens with expansion to 128, and 96 groups for light-strip film screens. The expansion arrangement must match the adapter board and pinout.
Does the RB6 have HUB75 connectors?
The specification identifies two 84-pin high-density connectors, JH1 and JH2, for a display adapter board or unit board. Select the adapter using the PDF pin definitions rather than assuming a direct HUB75 connection.
What power supply does the HD-RB6 require?
Use a DC supply within 3.8–5.5 V; the listed card power is 2.5 W. Disconnect power before wiring or changing connections.
