MRV328 LED Receiving Card - Novastar

Brand: Novastar

Model: MRV328

Type: reception signal card

Description: MRV328 is a new receiver card developed by Novastar, which supports up to 1/32 scanning of the number of pixels. One MRV328 loads up to 256 × 256 pixels. Supporting various features such as pixel level brightness and color calibration, fast 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 communication connectors, resulting in high stability. Supports up to 16 sets of parallel RGB data. Thanks to its EMC-compatible hardware design, the MRV328 has improved electromagnetic compatibility and is suitable for a variety of on-site settings.

Distinctive features for display effect enhancements:

• Pixel level brightness and chroma calibration. Working with NovaLCT and calibration platform (CalCube MiniLED V1.1.0 or later recommended), the receiving card supports brightness and chroma calibration on each LED, which can effectively remove color differences and chroma differences and greatly improve display brightness consistency 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 output
• Quick uploading of calibration coefficients. Upload the calibration coefficients quickly to the receiving cards to improve efficiency. The receiving card configuration parameters can be read back and saved to the local computer 
• Loop backup. The receiving card and sending card form a loop via the primary and backup line connections
• Setting of a pre-stored image in receiving card. The image displayed 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 connected to 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.
