Be complied with the whole description. 1.1 Storage and Transport Safety Pay attention to dust and water prevention. Avoid long-term direct sunlight. Do not place th

5、e products at the position near fire and heat. Do not place the products in an area containing explosive materials. Do not place the products in strong electromagnetic environment. Place the products at a stable position to prevent damage or personal injury caused by dropping. Save the packing box a

6、nd materials which will come in handy if you ever have to ship your products. For maximum protection, repack your product as it was originally packed at the factory. 1.2 Installation and Use Safety Only trained professionals may install the products. Do not insert and unplug （power cord plug） when t

7、he power is on. Ensure the safe grounding of the device. Always wear an anti-static wrist band and insulating gloves. Do not place the products in an area having more or strong shake. Perform dust removing regularly. Do not maintain the products without authorization but contact NovaStar as soon as

8、possible. Replace spare parts only with the same parts supplied by NovaStar. 2 Overview2 Overview A4s is a high-end receiving card developed by NovaStar, featuring small size and full functions with a single card loading capacity up to 256256 （PWM IC） pixels. A4s supports pixel level brightness and

9、chroma calibration, which removes color difference effectively and improves display consistency of LED images. In addition, it also supports image rotation in 90 increments, creating richer images and improving visual experiences. Software and hardware designs of the A4s concern the user deployment

10、as well as operating and maintenance scenarios, enabling easier deployment, more stable operating and more efficient maintenance. Advanced hardware design:Small size and thinner thickness save space for increasingly narrower cabinet space and smaller spacing between lamps. Use high-density connector

11、 which is resistant to dust and vibration and features high stability and high reliability. Assembly network transformer features simple design and improved magnetic compatibility, helping users products to successfully pass the EMC authentication. Useful software design:Support for LVDS transmissio

13、function） Support for 5-pin LCD module Support for image rotation in 90 increments 3 Characteristics Characteristics Description Supporting pixel level brightness and chroma calibration Pixel level brightness and chroma calibration on NovaLCT could remove color difference effectively, make the brigh

14、tness and chroma of the whole screen highly consistent, and improve display effect. Supporting image rotation in 90（Calibration of the rotated image not supported） On NovaLCT, the image on the screen can be set to rotate in the multiples of 90 （90, 180, 270 and Supporting the smart module （Customize

15、d function） The smart module is composed of Flash and MCU. Flash could store calibration coefficients and module information. MCU could communicate with the receiving card to realize monitoring over temperature, voltage and wiring communication status, as well as LED error detection. The smart modul

16、e could make monitoring unit smaller, requiring no independent monitoring card and saving cabinet space. Supporting LVDS transmission The transmission mode of low-voltage differential signaling （LVDS） is used, which reduces the number of data cables that connect the receiving cards HUB board to the

17、module, increases the transmission distance, improves the signal transmission quality, enhances the EMC effect, and better stabilizes the image output. 3.1 Improvement in Display Effect Supporting stored image setting of the receiving card On NovaLCT, the specified images could be set as the startup

18、 image and images used when there is no network or video source. Supporting module Flash management On NovaLCT, the module Flash could be enabled. Supporting monitoring over temperature, voltage and wiring status On NovaLCT, temperature, voltage and wiring status of the receiving card could be check

Supporting LCD module Support one-click module Flash calibration coefficient In the event of network outage, hold down the self-test button to read the module Flash calibration coefficient back to the receiving card. 3.3 Improvement in Hardware Reliability Supporting dual-card backup In the high

20、-reliability environment, single HUB board could be populated with two A4s receiving cards. In case that the main receiving card fails, the standby one will serve in a timely manner to ensure normal operation of the display. Supporting dual-power backup & detection Two power supplies could be simult

21、aneously connected, and operating status of the power supplies could be detected. Supporting hot backup Hot backup is used to improve business and connection reliability:Device redundant backup: The device connected to the receiving card improves business reliability through main and standby redundant mechanism. Only the main device is running at a certain time. The standby device begi
