NovaStar MRV408-S: 8-HUB75E LED Receiving Card
The NovaStar MRV408-S connects LED modules to the display control system through 8 standard HUB75E connectors. It supports up to 16 parallel RGB data groups and provides calibration, cabinet mapping and communication diagnostics for LED display setup and maintenance.
Its loading limit depends on the module driver IC. For an 8-bit video source at 60 Hz, one card supports 512 × 512 pixels with a PWM driver IC or 512 × 384 pixels with a common driver IC.

Image Processing and System Requirements
- Color management supports Rec.709, DCI-P3, Rec.2020 and custom gamuts. 18bit+ improves low-brightness grayscale performance.
- Pixel-level brightness and chroma calibration works with NovaStar’s calibration system. Quick seam adjustment and multi-batch adjustment help reduce differences between modules or cabinets.
- Individual RGB gamma adjustment works with NovaLCT and a supporting controller.
- Low latency is enabled by default. Reducing receiving-card latency to one frame requires driver ICs with built-in RAM.
- 3D requires a controller with 3D support. Image rotation in 90° increments is supported; free-angle rotation requires MCTRL R5 and SmartLCT.
- Calibration coefficient management includes upload, readback, saving to hardware and erasure. Uploading can use accelerated transfer where needed.
Cabinet Setup and Fault Diagnosis
Data group mapping shows the position of each group in a cabinet. Mapping 2.0 identifies controllers, Ethernet ports and receiving cards; cabinet resolution mapping supports a minimum of 36 × 20 pixels. Stored-image settings determine what appears at startup or when the input signal or Ethernet connection is lost.
Temperature and voltage monitoring, cabinet LCD support, bit-error detection and Ethernet disconnection detection help with maintenance. Firmware and configuration parameters can be read back to a local computer. Loop backup uses primary and backup line connections, while dual configuration backup and dual program backup provide recovery options.

Frequently Asked Questions
How many LED module connectors are on the MRV408-S?
The card has 8 standard HUB75E connectors and supports up to 16 groups of parallel RGB data. Check your module pinout and cabinet wiring against the specification before installation.
Does every MRV408-S setup support 512 × 512 pixels?
No. That maximum applies to a PWM driver IC with an 8-bit video source at 60 Hz. With a common driver IC under the same source conditions, the limit is 512 × 384 pixels.
What are the MRV408-S dimensions and input voltage?
The card measures 91.6 × 107.5 × 19.3 mm and accepts DC 3.8 V to 5.5 V. Its net weight is 73.7 g.
Can the MRV408-S help locate Ethernet communication faults?
Yes. It supports bit-error detection, Ethernet cable disconnection detection and Mapping 2.0 to help identify receiving-card locations and wiring. Temperature and voltage can also be monitored.
How do I display a test pattern on the MRV408-S?
According to the specification, disconnect the Ethernet cable and press the self-test button twice to display the test pattern. Press the button again to switch patterns.
