Configuration, Monitoring and Display Adjustment
- Read back configuration files: retrieve the receiving card configuration when maintaining a compatible display system.
- Copy programs: use the supported program copy function when configuring receiving cards.
- Check operating conditions: monitor temperature, supply voltage and Ethernet communication status during troubleshooting.
- Adjust image uniformity: apply per-pixel brightness and chromaticity calibration as part of display setup.
- Set a pre-stored picture: configure the supported stored-image function for your installation.
Check Compatibility Before Ordering
Support for MRV320 functions does not by itself establish a drop-in replacement for every cabinet. Compare the existing card label, board connectors, HUB board, module scan configuration, power requirements, firmware and receiving-card configuration file.
For a replacement check, provide a clear photo of the existing card and its connectors, the LED module specifications, cabinet pixel dimensions and sending controller model. Back up the working display configuration before replacing hardware.
