Customer question: What is the safe process for configuring a used receiving card?
English explanation
Begin by identifying the exact receiving-card model, hardware revision, module structure, driver IC, scan mode, cabinet resolution and project zone. Save the current configuration before editing. If the display is still working, preserve that working state and export the configuration with a clear project and date name. Use the project-specific RCFGX or equivalent file only after confirming that it matches the physical module and receiver. Do not use a file from another screen because the pitch or cabinet size looks similar. In NovaLCT, confirm the correct screen object, receiver selection, data group, mapping, brightness and refresh-related settings. Send the change to one known-good receiver or cabinet first, then test. Save to hardware only after the result is confirmed. Use grid, arrows, black, white, RGB, grayscale and text patterns after sending. If the image is distorted, mirrored, partially missing or colour-shifted, stop and restore the backup instead of making several changes together. Software version and controller/receiver firmware are separate; do not downgrade a working firmware package as a trial. Keep the original file, test file, final file, screenshots and result in the service record.
Service boundary
Configuration and firmware are model-specific. Factory confirmation is required when hardware revision or compatibility is uncertain. —
