Configuration, calibration and monitoring
The card supports configuration-file readback, a pre-stored picture, and pixel-by-pixel brightness and chromaticity calibration. Monitoring functions include board temperature, supply voltage and Ethernet cable communication status.
The three output modes use a common program and software without a customized program. Their 50-pin assignments differ: match the selected data mode to the HUB board and module wiring before connecting an existing installation. The PDF below contains the complete JH1/JH2 assignments and serial decoding circuit.
Model identification
MRV500-1 is the top-mounted male-connector model. The same specification also lists MRV500-2 with male connectors underneath, MRV500-3 with female connectors on top, and MRV500-4 with female connectors underneath. Check the full suffix and physical connector position when identifying a board.

No. This listing identifies the MRV500-1 as discontinued and no longer available. Its specifications remain here for maintenance and identification of existing displays.
What resolution does the MRV500-1 support?

What is the difference between MRV500-1 and MRV300?
NovaStar describes the MRV500-1 as the EMC version of the MRV300, intended to reduce electromagnetic radiation from the overall system. This does not establish that every module and HUB board can be interchanged without checking wiring and configuration.
Which data output modes are available?
The card 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 pinout for the selected mode in the PDF.
How do I distinguish MRV500-1 from MRV500-2, MRV500-3 and MRV500-4?
MRV500-1 has male connectors on top. MRV500-2 has male connectors underneath; MRV500-3 has female connectors on top; MRV500-4 has female connectors underneath. Check the model label and connector arrangement together.
