A7 Receiving Card

Product No : A7
Update Time : 22 April 2020
฿0.00

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 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.

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 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 correction.

 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 monitoring of Ethernet cable communication status (Supported by dedicated firmware program).

 Support for 5-pin LCD module.

 Support for image rotation in 90° increments.

Supporting pixel level brightness and chroma calibration : Working with NovaLCT and NovaCLB, A7 supports brightness 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°).

Supporting quick seam correction : Working with NovaLCT, A7 supports quick adjustment of bright and dark 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. 

ปรับปรุง การบำรุงรักษา

Supporting the smart 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 the 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 and saving cabinet space. 

Supporting LVDS transmission (Supported by 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 card's HUB board to the module, increases the transmission distance, improves the signal transmission quality, and better stabilizes 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, then the target cabinet will display the cabinet number and Ethernet port information, and the user could get the receiving card’s 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 images 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.

Supporting monitoring voltage and temperature of itself : The voltage and temperature of the receiving card itself can be monitored without using other peripherals. The monitoring data can be checked on NovaLCT.

Supporting LCD module : Supports NovaStar's 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.

การปรับปรุงของฮาร์ดแวร์

Supporting dual-card backup : In the high-reliability environment, single HUB board could be populated with two A7 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 Supporting loop backup  : Two power supplies could be simultaneously connected, and operating status of the power supplies could be detected. 

Supporting loop backup : HUB’s Ethernet port improves the reliability for the serial connection of the receiving card through main and standby redundant mechanism. Among the main and standby serial connection lines, if one fails, the other will begin to work to ensure the normal operation of the display.

การปรับปรุงซอฟต์แวร์

Supporting readback of firmware version : On NovaLCT, the firmware versions of the receiving card can be read back.

Supporting dual-backup and restoring of the calibration coefficient

Calibration coefficients could be saved to both the factory area and application area at the same time.

Calibration coefficients in the factory area is default as the delivery value, while the calibration coefficient in the application area could be modified or be restored to the factory reset by the user on NovaLCT.

Supporting readback of configuration file

 On NovaLCT, the receiving card configuration parameters can be backed up to the receiving card.

 On NovaLCT, the receiving card configuration parameters can be read back.
