Novastar MRV432 LED Receiving Card

Novastar MRV432 LED Receiving Card Description

The Novastar MRV432 LED Receiving Card is a high-performance solution designed for professional LED display systems. With a maximum loading capacity of 512×512 pixels per card, it provides pixel-level image optimization and powerful reliability features for consistent display performance across applications.

Certifications:
RoHS, EMC Class A

Product Features:
● Display Quality Enhancements
– Pixel-Level Calibration: Supports brightness and chroma calibration for each LED pixel, ensuring uniformity and high color fidelity.
– Dark/Bright Line Adjustment: Instantly adjusts splicing line artifacts between modules or cabinets for improved visual continuity.
– 3D Compatibility: Supports 3D output when paired with compatible sending cards.
– RGB Gamma Control: Enables individual Gamma adjustment for red, green, and blue channels via NovaLCT V5.2.0+, allowing finer grayscale management and improved white balance.
– Image Rotation: Supports image rotation at 0°, 90°, 180°, and 270°.
● Maintainability & Diagnostics
– Mapping Function: Displays receiving card ID and port info for easier layout identification and troubleshooting.
– Custom Startup Image: Supports pre-stored images to display during system boot or signal loss.
– Onboard Monitoring: Real-time voltage and temperature monitoring without external sensors.
– Cabinet LCD Interface: Displays critical stats such as temperature, voltage, uptime, and total runtime.
– Bite Error Detection: Monitors Ethernet port quality and error packets for network health diagnostics.
– Firmware and Configuration Backup: Allows readback and backup of firmware and configuration files using NovaLCT V5.2.0 or later.
● Reliability & Redundancy
– Loop Backup Support: Ensures uninterrupted display even if one Ethernet path fails.
– Dual Config Backup: Stores configuration parameters in both application and factory zones for restoration flexibility.
– Dual Firmware Backup: Prevents update-related failures by maintaining two firmware copies in the card.

Appearance
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 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 application area of the receiving card at the factory to avoid the problem that the receiving card may get stuck abnormally during program update.

Indicators

Indicator	Color	Status	Description
Running indicator	Green	Flashing once every 1s	The receiving card is functioning normally. Ethernet cable connection is normal, and video source input is available.
		Flashing once every 3s	Ethernet cable connection is abnormal.
		Flashing 3 times every 0.5s	Ethernet cable connection is normal, but no video source input is available.
		Flashing once every 0.2s	The receiving card failed to load the program in the application area and is now using the backup program.
		Flashing 8 times every 0.5s	A redundancy switchover occurred on the Ethernet port and the loop backup has taken effect.
Power indicator	Red	Always on	The power input is normal.
