NovaStar MRV328 - 256 x 256 Pixel Resolution Receiving Card

The MRV328 is a general receiving card that supports up to 1/32 scan. For PWM driver ICs, a single MRV328 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 MRV328 can significantly improve the display effect and user experience.

The MRV328 uses 8 standard HUB75E connectors for communication, resulting in high stability. It supports up to 16 groups of parallel RGB data. Thanks to its EMC compliant hardware design, the MRV328 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.
• Quick adjustment of dark or bright lines
  • The dark or bright lines caused by splicing of modules or cabinets can be adjusted to improve the visual experience. The adjustment is easy and takes effect immediately..
• 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.
• 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.
• Firmware program readback
  • The receiving card firmware program can be read back and saved to the local computer.
  • NovaLCT V5.2.0 or later is required.
• 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 program backup
  • Two copies of firmware program are stored in the application area of the receiving card at the factory to avoid the problem that the receiving card may get stuck abnormally during program update.
