Introduction
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.
Certifications
RoHS, EMC Class A
Improvements to Display Effect
l Pixel level brightness and chromacalibration
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.
l Quick adjustment of dark or brightlines
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 effectimmediately.
l 3Dfunction
Working with the sending card that supports 3D function, the receiving card supports 3D image output.
l Individual gamma adjustment forRGB
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.
l Image rotation in 90°increments
The display image can be set to rotate in multiples of 90° (0°/90°/180°/270°).
Improvements to Maintainability
l Mappingfunction
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.
l Setting of a pre-stored image in receivingcard
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.
l Temperature and voltage monitoring
The receiving card temperature and voltagecan be monitored without usingperipherals.
l CabinetLCD
The LCD module of the cabinet can display the temperature, voltage, single run time and total run time of the receiving card.
Improvements to Reliability
l Bit errordetection
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.
l Firmware programreadback
The receiving card firmware program can be read back and saved to the localcomputer.
NovaLCT V5.2.0 or later is required.
l Configuration parameterreadback
The receiving card configuration parameters can be read back and saved to the local computer.
l Loopbackup
The receiving card and sending card form aloop via the main and backup line connections. If a fault occurs at a location of the lines, the screen can still display the imagenormally.
Appearance
l Dual programbackup
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.
