Features
MRV220 is the receiving card of Nova with 28-group data mode. It has the following features:
1) Single card outputs 24-group of RGB data; 2) Single card outputs 28-group of RGB data; 3) Single card outputs64-group of serial data; 4) Single card support resolution 256x226; 5) Configuration fileread back; 6) Temperature monitoring;
7) Ethernet cable communication status detection;
8) Power supply voltage detection;
9) Pixel-by-pixel brightness and chromaticity calibration, Brightness and chromaticity calibration coefficients for each LED; 10) Supports dual power backup function: It supports two-way power detection and screen brightness will be adjusted automatically when
power failure occurs in any way of the power. NOTE: PWR1_S and WR2_S default to normal. Power shall be guaranteed to be pulled down to GND after power failure occurs; 11) Comply with RoHS standard;
12) Comply with EU CE-EMC Class A standard.
