NovaStar MRV412-S Receiving Card Overview
The NovaStar MRV412-S is an LED receiving card with 12 standard HUB75E connectors and up to 24 groups of parallel RGB data. It connects to LED modules within the display cabinet and receives data from a sending card through Gigabit Ethernet.
With an 8-bit video source at 60 Hz, the maximum resolution per card is 512 × 512 pixels with a PWM driver IC, or 512 × 384 pixels with a common driver IC. Check the module driver IC and cabinet configuration when selecting the card.

Display Adjustment and Calibration
- Color management supports Rec.709, DCI-P3, Rec.2020 and custom color gamuts.
- 18bit+ improves grayscale performance at low brightness. Pixel-level brightness and chroma calibration works with NovaStar’s calibration system.
- Quick adjustment of dark or bright lines corrects visible seams; multi-batch adjustment helps match cabinets or modules from different production batches.
- Individual RGB gamma adjustment requires NovaLCT and a controller that supports the function.
- Low latency is enabled by default. One-frame latency at the receiving-card end requires module driver ICs with built-in RAM.
- 3D output requires a controller with 3D support. Rotation in 90° increments is supported; free-angle rotation requires the MCTRL R5 controller and SmartLCT.
- Calibration coefficients can be uploaded, read back, saved to hardware and erased, with accelerated uploading supported when needed.
Setup, Monitoring and Backup
Data group mapping and Mapping 2.0 help identify cabinet wiring and receiving-card locations. The card supports stored images for startup or signal loss, temperature and voltage monitoring, and a cabinet LCD connection. Bit-error detection and Ethernet disconnection detection assist with communication troubleshooting.
Firmware and configuration parameters can be read back to a computer. Reliability functions include loop backup, dual backup of configuration parameters and dual program backup. Loop backup requires primary and backup line connections between the controller and receiving cards.

Frequently Asked Questions
How many HUB75E connectors does the MRV412-S have?
It has 12 standard HUB75E connectors and supports up to 24 groups of parallel RGB data.
What resolution can one MRV412-S receiving card load?
At 60 Hz with an 8-bit video source, the limit is 512 × 512 pixels with a PWM driver IC or 512 × 384 pixels with a common driver IC. The driver IC type is part of the specification, so the two limits are not interchangeable.
What power supply voltage does the MRV412-S require?
The specified input range is DC 3.8 V to 5.5 V. Rated current is 0.4 A at 4.2 V, and rated power consumption is 1.68 W.
Does the MRV412-S support low latency and 3D?
Yes. One-frame latency at the receiving-card end requires driver ICs with built-in RAM. For 3D output, the controller must also support 3D.
Can the MRV412-S rotate an LED display image?
It supports rotation by 0°, 90°, 180° and 270°. Rotation at other angles requires the dedicated MCTRL R5 controller and SmartLCT software.
