8、nsulating gloves. Do not place the product in an area having frequent or strong shake. Perform dust removing regularly. Contact NovaStar for maintenance at any time, rather than have the product disassembled and maintained by non-professionals without authorization. Replace faulty parts only with th

9、e spare parts supplied by NovaStar. 2 Overview2 Overview A7 is a high-end receiving card developed by NovaStar, featuring small size and large loading capacity with a single card loading up to 512 x 256(PWM IC) pixels. A7 supports pixel level brightness and chroma calibration by working with NovaLCT

10、 and NovaCLB to realize calibration on each pixel. It can effectively remove color difference and greatly improve LED display image consistency, presenting smoother images to users. In addition, it also supports image rotation in 90 increments, creating richer images and improving visual experiences

11、. Software and hardware designs of the A7 concern the user deployment as well as operating and maintenance scenarios, enabling easier deployment, more stable operating and more efficient maintenance. Advanced hardware design: The small-size hardware design is applicable to scenarios of small cabinet

12、 space and small pixel pitch. The used DDR3 connectors have stable contact performance and good compatibility. Useful software design: Support for LVDS transmission (Supported by dedicated firmware program). Support for smart module (Supported by dedicated firmware program). Support for quick seam c

13、orrection. Support for 3D function. Support for auto module calibration. Support for Mapping function. Support for pre-stored image setting of the receiving card. Support for module Flash management. Supports monitoring voltage and temperature of itself without using other peripherals. Support for m

14、onitoring of Ethernet cable communication status (Supported by dedicated firmware program). Support for 5-pin LCD module. Support for image rotation in 90 increments. Features Description Supporting pixel level brightness and chroma calibration Working with NovaLCT and NovaCLB, A7 supports brightnes

15、s and chroma calibration on each pixel. Supporting image rotation in 90 increments (Calibration not supported after rotation) On NovaLCT, the image on the screen can be set to rotate in the multiples of 90 (90, 180, 270 and 360). Working with NovaLCT, A7 supports quick adjustment of bright and dark

16、lines, which can remove the seams between modules and between cabinets. Supporting 3D function On NovaLCT or operation panel of controllers which support 3D function, you can enable 3D function and set the 3D parameters to make the LED screen display 3D effects. Features Description Supporting the s

17、mart module (Supported by dedicated firmware program) 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 for th

18、e module. Working with the driver chip, A7 supports open circuit detection on LED. The smart module could make monitoring unit smaller, requiring no independent monitoring card 3.2 Improvement in Maintainability Features Description and saving cabinet space. Supporting LVDS transmission (Supported b

19、y dedicated firmware program) 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 module, increases the transmission distance, improves the signal transmission quality, and better stabil

20、izes the image output. Supporting auto module calibration After the module has been replaced, the receiving card can automatically read the new module ID and calibration coefficient which could be saved to calibration system files. Supporting Mapping function Enable the Mapping function on NovaLCT,

21、then the target cabinet will display the cabinet number and Ethernet port information, and the user could get the receiving cards location and wiring route. Supporting setting of images pre-stored of the receiving card On NovaLCT, the specified images could be set as the screen startup image and ima

22、ges used when the Ethernet cable is disconnected or no video source signal is available. Supporting module Flash management On NovaLCT, lamp panel Flash could be managed. The voltage and temperature of the receiving card itself can be monitored without using other peripherals. The monitoring data ca

23、n be checked on NovaLCT. Supporting LCD module Supports NovaStars general 5-pin LCD module. The LCD module is connected to the HUB board to display temperature, voltage, single operating time and total operating time of the receiving card. Support one-click application of calibration coefficient in module Flash In the event of network outage, hold down the selftest button to read the calibration coefficient in module Flash back to the receiving card. Features Description Supporting dual-card backup In the high
