Nova Star LED Receiving Card A4s LED Display Receiver

A4s is a general small receiving card developed by NovaStar. A single A4s loads up to 256×256 pixels. Supporting the pixel level brightness and chroma calibration, individual Gamma adjustment for RGB, and 3D functions, the A4s can greatly improve the display effect and user experience.

The A4s uses high-density connectors for communication to limit the effects of dust and vibration, resulting in high stability. It supports up to 24 groups of parallel RGB data or 64 groups of serial data (expandable to 128 groups of serial data). Its reserved pins allow for custom functions of users. Thanks to its EMC Class B compliant hardware design, the A4s has improved electromagnetic compatibility and is suitable to various on-site setups.

Features

Improvements to Reliability

Status detection of dual power supplies

When two power supplies are connected, their working status can be detected by the receiving card.

Loop backup

The receiving cards and the sending card form a loop via the main and backup line connections. If a fault occurs at a location of the lines, the screen can still display the image normally.

Dual backup of configuration parameters

The receiving card configuration parameters are stored in the application area and factory area of the receiving card at the same time. Users usually use the configuration parameters in the application area. If necessary, users can restore the configuration parameters in the factory area to the application area.

Dual backup of the application program

Two copies of the application program are stored in the receiving card at the factory to avoid the problem that the receiving card may get stuck due to program update exception.
