MRV308

Receiving Card

VMRV308QL is a powerful new receiving card, with a single card carrying 256×256 pixels.

VMRV308QL supports point-by-point brightness and chromaticity correction, effectively eliminating chromatic aberration, significantly improving the consistency of LED screen display, and bringing users a more delicate screen.

The hardware design and software design of VMRV308QL fully consider user deployment, system operation and maintenance scenarios, making deployment easier, running more stable, and maintaining more efficient.

Hardware design:

Integrate 8 standard HUB75 interfaces, free of connection to HUB board.
Using a gigabit network port, which can be connected to the PC side.

Software design:

Support point-by-point brightness and chromaticity correction.
Support receiving card pre-stored picture settings.
Support temperature, voltage, network cable communication and video

source signal state detection.

Support 5Pin LCD module.

Features

Support point-by-point brightness and chromaticity correction In the powerful LED studio, the brightness and chromaticity of each light spot are corrected to effectively eliminate chromatic aberration, so that the brightness and chromaticity of the display screen are highly consistent, and the picture quality of the display screen is improved.

Support receiving card pre-stored picture settings On the Powerful LED Studio, you can set the specified picture as the startup picture of the display, the picture when the network cable is disconnected and there is no video source signal.

Support temperature, voltage, network cable communication and video source signal state detection The temperature, voltage, network cable communication and video source signal status detection of the receiving card itself can be viewed on the powerful LED studio.

Support LCD module Support the universal 5pin LCD module of Qiangli. The LCD module is connected to the HUB board to display the temperature, voltage, single running time and total running time of the receiving card.

Support configuration file readback The configuration information stored in the receiving card can be read back on the powerful LED studio.

Support firmware version readback The firmware version of the receiving card can be read back on the Powerful LED Studio.
