Out of stock
The NovaStar MRV500-1 is an EMC LED receiving card for legacy LED display systems. NovaStar describes it as the EMC version of the MRV300. It uses two 50-pin output interfaces and supports separate RGBR, RGB and serial-data modes, with configuration readback, monitoring and pixel calibration functions.
Availability: EagerLED’s existing listing states that this model is out of production and no longer available. Use the information below to identify installed hardware and plan a replacement; a matching connector alone does not establish compatibility.
MRV500-1 specifications and interface modes
These values refer to the linked NovaStar specification Rev1.1.1, NS110100113. Its feature list states 256 × 226 pixels. That unusual value is retained as documented; the document does not attach a refresh-rate condition to that line.
| Item | Documented specification |
|---|---|
| Single-card resolution | 256 × 226 pixels in the Rev1.1.1 feature list; confirm the configuration required by the existing screen. |
| Output interfaces | Two 50-pin interfaces, JH1 and JH2; pin definitions depend on the selected data mode. |
| Parallel data modes | 16 groups of RGBR data or 20 groups of RGB data. |
| Serial data mode | 64 groups of serial data; the specification describes each data cable driving an LED bar independently. |
| Rated voltage | 3.3 V minimum, 5.0 V typical, 5.5 V maximum. |
| Rated current | 0.33 A minimum, 0.50 A typical, 0.55 A maximum. |
| Operating environment | −20°C to +70°C; 10%–90% humidity in the specification. |
| Thickness | Board approximately 1.6 mm; overall thickness including front/rear components approximately 18.5 mm. |
Match the HUB board and connector orientation
The three output modes are alternative configurations, not group counts to add together. Compare the JH1/JH2 pin tables with the installed HUB board, module wiring and scan arrangement. In 16-group mode, the document notes that the last group’s virtual R signal on each 50-pin HUB becomes decoding signal E for 1/32 scan.
The model suffix also matters. Rev1.1.1 lists MRV500-1 with male connectors on top, MRV500-2 with male connectors underneath, MRV500-3 with female connectors on top and MRV500-4 with female connectors underneath. These entries identify physical variants; they do not establish current stock or a suitable substitute for this discontinued listing.
Monitoring, calibration and EMC reference
Documented functions include configuration-file readback, temperature monitoring, Ethernet cable communication-status detection and power-supply voltage detection. Pixel-by-pixel brightness and chromaticity calibration stores coefficients for individual LEDs. A pre-stored picture can also be configured.
The specification lists EU CE-EMC Class B and RoHS compliance. These are the card’s documented references; they do not certify every completed LED display. Check the complete system’s cabling, cabinet design and applicable compliance documentation separately.

MRV500-1 FAQ
Does the MRV500-1 use standard HUB75E sockets?
The linked document defines two 50-pin interfaces, not direct HUB75E sockets. Check the matching HUB adapter and the selected data-mode pinout before choosing replacement hardware.
Can an MRV300 or another receiving card replace it directly?
The EMC relationship to MRV300 does not by itself confirm a direct replacement. Compare the driver IC, scan method, output data mode, pinout, power, mounting and saved configuration with the proposed card.
What should I provide for a replacement inquiry?
Send clear front/rear card photos, the HUB-board model, module pixel dimensions, cabinet layout, driver IC and scan details. Include the existing configuration file where available so the receiving-card choice can be checked against the actual display.
