NovaStar MRV220-1 - 256 x 256 Pixel Resolution Receiving Card

The MRV220 is a general receiving card developed by NovaStar. A single MRV220 supports resolutions up to 256x256@60Hz. Supporting various functions such as pixel level brightness and chroma calibration, quick adjustment of dark or bright lines, and 3D, the MRV220 can significantly improve the display effect and user experience.

The MRV220 uses 2 hub connectors for communication, resulting in high stability. It supports up to 28 groups of parallel RGB data or 64 groups of serial data. Thanks to its EMC Class B compliant hardware design, the MRV220 has improved electromagnetic compatibility and is suitable for various on-site setups.

Features

Improvements to Display Effect

• Pixel level brightness and chroma calibration
  • Working with NovaLCT and NovaCLB, the receiving card supports brightness and chroma calibration on each LED, which can effectively remove color discrepancies and greatly improve LED display brightness and chroma consistency, allowing for better image quality.
• Pixel level brightness and chroma calibration
  • Work with NovaStar's high-precision calibration system to calibrate the brightness and chroma of each pixel, effectively removing brightness differences and chroma differences, and enabling high brightness consistency and chroma consistency.
• 3D function
  • Working with the sending card that supports 3D function, the receiving card supports 3D image output.

Improvements to Maintainability

• Quick uploading of calibration coefficients
  • The calibration coefficients can be quickly uploaded to the receiving card, improving efficiency greatly.
• One click to apply calibration coefficients stored in module Flash
  • For modules with flash memory, if the Ethernet cable is disconnected, users can hold down the self-test button on the cabinet to upload the calibration coefficients in the memory of the module to the receiving card.
• Setting of a pre-stored image in receiving card
  • The image displayed on the screen during startup, or displayed when the Ethernet cable is disconnected or there is no video signal can be customized.
• Temperature and voltage monitoring
  • The receiving card temperature and voltage can be monitored without using peripherals.
• Cabinet LCD
  • The LCD module of the cabinet can display the temperature, voltage, single run time and total run time of the receiving card.
• Bit error detection
  • The Ethernet port communication quality of the receiving card can be monitored and the number of erroneous packets can be recorded to help troubleshoot network communication problems.
  • NovaLCT V5.2.0 or later is required.
• Status detection of dual power supplies
  • When two power supplies are connected, their working status can be detected by the receiving card.
• Configuration parameter readback
  • The receiving card configuration parameters can be read back and saved to the local computer.

Improvements to Reliability

• Loop backup
  • The receiving card and sending card form a loop via the main and backup line connections. If a fault occurs at a location of the lines, the screen can still display the image normally.
• Dual backup of the application program
  • Two copies of the application program are stored in the receiving card at the factory to avoid the problem that the receiving card may get stuck due to program update exception.
