Calibration and Maintenance Functions
Brightness and chromaticity calibration uses coefficients for individual LEDs to adjust differences across the display. Temperature, supply-voltage and Ethernet communication status monitoring provide information for troubleshooting. The card also supports connection to a monitoring card.
Configuration-file readback allows existing settings to be retrieved, and program copying is supported. Pre-stored picture settings are available. The listing describes high grayscale and high refresh operation without specifying numerical limits, so no refresh-rate or grayscale number is assigned here.
Replacement and Installation Checks
When selecting a replacement, match the MRV350-1 model, board connections, module data arrangement and existing configuration. The listed RGBR, RGB and serial group counts describe supported data arrangements, rather than a combined group total. Confirm the relay’s electrical rating and the board’s power requirements before wiring; those values are not supplied in the existing product information.

Frequently Asked Questions
What distinguishes MRV350-1 from the MRV320 described in this listing?
The product information states that MRV350-1 supports MRV320 functions and adds a relay module with one relay control function. Physical replacement compatibility still requires matching the board and module connections.
What resolution is listed for one MRV350-1?
The listed single-card resolution is 256 × 226 pixels. Confirm the existing display configuration and module requirements when using it as a replacement.
Which data outputs are supported?
The listing specifies 16 groups of RGBR data, 20 groups of RGB data and 64 groups of serial data. These are separate data arrangements, not an additive total.
Does MRV350-1 support pixel calibration?
Yes. Pixel-by-pixel brightness and chromaticity calibration is listed, with calibration coefficients for individual LEDs.
What maintenance information can the card provide?
The card supports temperature and supply-voltage monitoring, Ethernet communication status detection, configuration-file readback and program copying. Monitor card connection is also listed.
