Novastar (Class A) LED Receiving Card MRV532 LED Display Controller

The MRV532 is a receiving card designed for PWM driver ICs by NovaStar. For 8bit video sources, a single card supports resolutions up to 512×512@60Hz. For 10bit or 12bit video sources, a single card supports resolutions up to 512×384@60Hz. The MRV532 also supports various functions such as Seam Correction, Pixel Level Brightness and Chroma Calibration, Quick Adjustment of Dark or Bright Lines, Low Latency, 3D, and 90° Image Rotation. As a result, it can significantly improve the display effect and user experience.
The MRV532 uses 10 standard HUB320F connectors to ensure highly stable communication,
supporting up to 40 groups of RGB real pixel data, 40 groups of 3-color sub-pixel data, or 30 groups of 4-color sub-pixel data.

Improvements to Display Effect

Pixel Level Brightness and Chroma Calibration
Work with NovaStar's high-precision calibration system to calibrate the brightness and
chroma of each pixel, effectively eliminating differences and enabling high consistency for both brightness and chroma.

Seam Correction with Mobile App
Use the mobile app to automatically or manually correct the different brightness of seams caused by splicing of modules or cabinets to improve the visual experience. (Work with the TU series)

Quick Adjustment of Dark or Bright Lines
The different brightness of seams caused by splicing of modules or cabinets can be
corrected to improve the visual experience. The correction is easy and takes effect
immediately.

Low Latency
The latency of video source on the receiving card end can be reduced to 1 frame (only whenusing modules with driver IC with built-in RAM).

3D
Work with the controller that supports 3D function to enable 3D output.

90° Image Rotation
The display image can be rotated in multiples of 90° (0°/90°/180°/270°).

Improvements to Maintainability

Automatic Module Calibration
After a new module with flash memory is installed to replace the old one, the calibration coefficients stored in the flash memory can be automatically uploaded to the receiving card when it is powered on, which ensures unchanged uniform display brightness and chroma.

Module Auto Light-up (dedicated firmware required)
After a new module with flash memory is installed to replace the old one, the configuration file stored in the memory can be automatically uploaded to the receiving card when it is powered on. The ensures the module can be lighted up without issue.

Module Flash Management
For modules with flash memory, the information stored in the memory can be managed. The
calibration coefficients and module ID can be stored and read back.

One-click to Apply Calibration Coefficients in Module Flash
For modules with flash memory, when 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.

Mapping 1.1
The cabinets can display the controller number, receiving card number, and Ethernet port information, allowing users to easily obtain the locations and connection topology of
receiving cards.

Settings of a Stored Image in the 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
Real-time monitoring of the temperature and voltage of the receiving card, without the
need for other external devices.

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.

Firmware Program Readback
The receiving card firmware program can be read back and saved to the local computer.

Configuration Parameter Readback
The receiving card configuration parameters can be read back and saved to the local
computer.

Improvements to Reliability

Dual NCP Backup
The NCP file is stored in the application area and factory area of the receiving card at the same time. Users typically use the NCP file in the application area. However, users can retrieve the NCP file from the factory area when performing a factory reset.

Loop Backup
The receiving card and controller form a loop via the primary and backup line connections.
When a fault occurs at a location of the lines, the screen can still display the image normally.

Dual Backup of Configuration Parameters
The receiving card configuration parameters are stored in the application area and factory area of the receiving card at the same time. Users usually use the configuration parameters in the application area. If necessary, users can restore the configuration parameters in the factory area to the application area.

Dual Program Backup
Two copies of firmware program are stored in the receiving card at the factory to avoid the problem that the receiving card may get stuck abnormally during program update.
