Experience Smooth And High-Definition Display With Novastar DH7512-S LED Screen Receiving Card

⬤Pixel level brightness and chroma calibration Work with NovaStar’s high-precision calibration system to calibrate the brightness and chroma of each pixel, effectively removing brightness differences and chroma differences, and enabling high brightness consistency and chroma consistency. ⬤Quick adjustment of dark or bright lines The dark or bright lines caused by splicing of modules and cabinets can be adjusted to improve the visual experience. The adjustment can be easily made and 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 controller that supports this function, the receiving card supports individual adjustment of red gamma, green gamma and blue gamma, which can effectively control image non- uniformity 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°).

The DH7512-S is a general receiving card developed by Xi’an NovaStar Tech Co., Ltd. (hereinafter referred to as NovaStar). A single DH7512-S supports resolutions up to 512×384@60Hz (NovaLCT V5.3.1 or later required). Supporting various functions such as pixel level brightness and chroma calibration, quick adjustment of dark or bright lines, 3D, individual gamma adjustment for RGB, and image rotation in 90° increments, the DH7512-S can significantly improve the display effect and user experience. The DH7512-S uses 12 standard HUB75E connectors for communication and supports up to 24 groups of parallel RGB data. On-site setup, operation, and maintenance were all taken into account when designing the hardware and software of the DH7512-S, allowing for an easier setup, more stable operation, and more efficient maintenance.RoHS, EMC Class ATo make molds or trepan mounting holes, please contact NovaStar for a higher-precision structural drawing.

⬤Mapping function The cabinets can 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 on the screen during startup, or displayed when the Ethernet cable is disconnected or there is no video signal can be customized. ⬤Temperature and voltage monitoring The receiving card temperature and voltage can be monitored without using peripherals. ⬤Cabinet LCD The LCD module of 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. ⬤Firmware program readback The receiving card firmware program can be read back and saved to the local computer. NovaLCT V5.2.0 or later is required. ⬤Configuration parameter readback The receiving card configuration parameters can be read back and saved to the local computer. ⬤Loop backup The receiving card and sending card form a loop via the primary and backup line connections. If a fault occurs at a location of the lines, the screen can still display the image normally.⬤Dual program backup Two copies of firmware program are stored in the application area of the receiving card at the factory to avoid the problem that the receiving card may get stuck abnormally during program update.
