Introduction The 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 significantly 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 for various on-site setups. Features Improvements to Display Effect Pixel level brightness and chroma calibration Working with NovaLCT and calibration platform (CalCube MiniLED V1.1.0 or later recommended), the receiving card supports brightness and chroma calibration on each LED, which can effectively remove brightness differences and chroma differences and greatly improve display brightness consistency and chroma consistency, allowing for better image quality. Quick adjustment of dark or bright lines The dark or bright lines caused by splicing of cabinets or modules can be adjusted to improve the visual experience. This function is easy to use and the adjustment takes effect immediately. 3D function Working with the sending card that supports 3D function, the receiving card supports 3D image output. Individual gamma adjustment for RGB Working with NovaLCT (V5.2.0 or later) and the sending card that supports this function, the receiving card supports individual adjustment of red gamma, green gamma and blue gamma, which can effectively control image nonuniformity at low grayscale conditions and white balance offset, allowing for a more realistic image. Image rotation in 90° increments The display image can be set to rotate in multiples of 90° (0°/ 90°/180°/270°). Improvements to Maintainability Smart module (dedicated firmware required) Working with the smart module, the receiving card supports module ID management, storage of calibration coefficients and module parameters, monitoring of module temperature, voltage and flat cable communication status, LED error detection, and recording of the module run time. Quick uploading of calibration coefficients www.novastar.tech 1 A4s Receiving Card Specifications The calibration coefficients can be quickly uploaded to the receiving card, improving efficiency greatly. Module Flash management For modules with flash memory, the information stored in the memory can be managed. The calibration coefficients and module ID can be stored and read back. One click to apply calibration coefficients in module Flash For modules with flash memory, when the Ethernet cable is disconnected, users can hold down the self-test button on the cabinet to upload the calibration coefficients in the flash memory of the module to the receiving card. Mapping function The cabinets display the receiving card number and Ethernet port information, allowing users to easily obtain the locations and connection topology of receiving cards. Setting of a pre-stored image in receiving card The image displayed during startup, or displayed when the Ethernet cable is disconnected or there is no video signal can be customized. Temperature and voltage monitoring The temperature and voltage of the receiving card can be monitored without using peripherals. Cabinet LCD The LCD module connected to the cabinet can display the temperature, voltage, single run time and total run time of the receiving card. Bit error detection The Ethernet port communication quality of the receiving card can be monitored and the number of erroneous packets can be recorded to help troubleshoot network communication problems. NovaLCT V5.2.0 or later is required. Status detection of dual power supplies When two power supplies are used, their working status can be detected by the receiving card. Firmware program readback The firmware program of the receiving card can be read back and saved to the local computer. NovaLCT V5.2.0 or later is required. Configuration parameter readback The configuration parameters of the receiving card can be read back and saved to the local computer. LVDS transmission (dedicated firmware required) Low-voltage differential signaling (LVDS) transmission is used to reduce the number of data cables from the hub board to module, increase the transmission distance, and improve the signal transmission quality and electromagnetic compatibility (EMC). Improvements to Reliability Loop backup The receiving cards and the sending card form a loop via the primary and backup line connections. When 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 program backup Two copies of firmware 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. www.novastar.tech 2 Appearance A4s Receiving Card Specifications All product pictures shown in this document are for illustration purpose only. Actual product may vary. Indicators Indicator Color Running Green indicator Power Red indicator Status Description Flashing once every 1s The receiving card is functioning normally. Ethernet cable connection is normal, and video source input is available. Flashing once every 3s Ethernet cable connection is abnormal. Flashing 3 times every 0.5s Ethernet cable connection is normal, but no video source input is available. Flashing once every 0.2s The receiving card failed to load the program in the application area and is now using the backup program. Flashing 8 times every 0.5s A redundancy switchover occurred on the Ethernet port and the loop backup has taken effect. Always on The power input is normal. Dimensions The board thickness is not greater than 2.0 mm, and the total thickness (board thickness + thickness of components on the top and bottom sides) is not greater than 8.5 mm. Ground connection (GND) is enabled for mounting holes. www.novastar.tech 3 A4s Receiving Card Specifications Tolerance: ±0.3 Unit: mm Note The distance between outer surfaces of the A4s and hub boards after their high-density connectors fit together is 5.0 mm. A 5-mm copper pillar is recommended. www.novastar.tech 4 Pins 24 Groups of Parallel RGB Data A4s Receiving Card Specifications LCD CS signal LCD RS signal LCD clock signal LCD data signal LCD
