NovaStar MRV560-1 EMC LED receiving card
NovaStar describes the MRV560 series as the EMC version of MRV360, designed to reduce system electromagnetic radiation. The MRV560-1 is the standard variant with male connectors on the top side. Check this suffix when replacing a card, because other MRV560 variants use different connector positions or genders.
Output modes and monitoring
Two 50-pin hub interfaces support three data modes: 16 groups of RGBR′ parallel data, 20 groups of RGB parallel data, or 64 groups of serial data. The specification provides a different output pin table for each mode. In serial mode, each data cable can drive one LED bar independently.
MOM stores calibration coefficients and LED module information. The card supports configuration readback, a pre-stored image, pixel-level brightness and chromaticity calibration, and monitoring of temperature, Ethernet cable communication and supply voltage. A monitoring card can be connected for additional monitoring.

These entries identify connector arrangements in the specification. They do not establish current stock availability for each variant.
Frequently Asked Questions
What is the difference between MRV560-1 and other MRV560 variants?
MRV560-1 has top-side male connectors. MRV560-2 uses bottom-side male connectors, MRV560-3 top-side female connectors and MRV560-4 bottom-side female connectors.
Which data output modes does MRV560 support?
The series supports 16 groups of RGBR′ parallel data, 20 groups of RGB parallel data, or 64 groups of serial data through two 50-pin interfaces. Use the correct pin table for the selected mode.
What resolution is listed for MRV560-1?
The linked MRV560 Rev1.1.2 specification states 256 × 226. No refresh rate is given with that feature entry; confirm the required cabinet configuration for the supplied card.
What is the MOM interface used for?
MOM stores calibration coefficients and LED module information. The J4 pin definition is retained below and in the downloadable specification.
What can the MRV560-1 monitor?
The documented monitoring functions cover temperature, Ethernet cable communication status and power-supply voltage. A monitoring card can also be connected.
