The original text and table disagree on RGB group count and maximum pixel loading. Both values are retained with their source identified; neither is presented as a resolved maximum for every M-RA30 revision.
Configuration and maintenance
The listing describes support for PWM, conventional and point-detection driver ICs, stored startup pictures, parameter monitoring and recovery functions. Match these functions to the actual driver and system configuration before use.
Frequently Asked Questions
How many RGB data groups does the M-RA30 have?
The original feature list states 20 RGB groups, while its parameter table states 24. The listing also names 12 HUB75 interfaces. Confirm the hardware revision and pinout before deciding which data arrangement applies.
Is the maximum load 64K or 96K pixels?
Both appear in the source page: 64K in the feature text and 96K in the table. The typical table entry is 128 × 128. Obtain the specification for the exact board before designing for a maximum load.
What supply voltage and current are listed?
The listed input range is 3.5–6 V. The original table gives 0.6 A typical working current and 1.0 A maximum, with a separate 3.0 A protection-current entry.
Does the M-RA30 support cable backup and calibration?
The listing describes network-cable backup and point-by-point brightness and color correction. Confirm the module, driver and configuration requirements; backup functions do not guarantee that a display can never go black.
Does the stated fiber distance mean the card has a fiber port?
No direct fiber interface is established by the available information. The original table lists 500 m multimode and 10 km single-mode transmission figures, but does not identify the required optical equipment. Verify the full transmission system before applying those figures.
