A4s Receiving Card

Supports individual Gamma adjustment for RGB : A4s can work with the independent controllers and NovaLCT (V5.2.0 or later) which support individual Gamma adjustment for RGB to effectively control problems such as image non-uniformity under low grayscale and white balance offset by adjusting red Gamma, green Gamma and blue Gamma respectively, making image more real.

Supports pixel level brightness and chroma calibration : Working with NovaLCT and NovaCLB, A4s supports brightness and chroma calibration on each pixel.

Supports 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° (0°, 90°, 180°, and 270°).

Supports quick seam correction : Working with NovaLCT, A4s supports quick adjustment of bright and dark lines, which can remove the seams between modules and between cabinets.

Supports 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.

Supports Mapping function : Enable the Mapping function on NovaLCT, then the target cabinet will display the cabinet number and Ethernet port information, and the user can easily get the receiving card’s location and data flow. 

Supports the smart module (Supported by dedicated firmware program) : The smart module is composed of Flash and MCU. Flash can store calibration coefficients and module information. MCU can communicate with the receiving card to realize monitoring over temperature, voltage and wiring communication status for the module. Working with the driver chip, A4s supports open circuit detection on LED. The smart module can make monitoring unit smaller, requiring no independent monitoring card and saving cabinet space.

Supports LVDS transmission (Supported by dedicated firmware program) : Low-voltage differential signaling (LVDS) transmission 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, enhances the electromagnetic compatibility (EMC), and better stabilizes the image output.

Supports setting of images pre-stored of the receiving card : On NovaLCT, the specified images can be set as the screen startup image and images used when the Ethernet cable is disconnected or no video source signal is available.

Supports module Flash management : On NovaLCT, lamp panel Flash can be managed.

Supports 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.

Supports 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.

 Supports cabinet LCD backlight control by working with NovaLCT (V5.2.0 or later).

 Supports cabinet run time reset by working with NovaLCT (V5.2.0 or later).

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.

Supports dual-power backup detection : Two power supplies can be simultaneously connected, and operating status of the power supplies can be detected.

Supports 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.

Supports bit error detection : A4s can work with NovaLCT (V5.2.0 or later) to detect the packet loss of the transmission link during communication between receiving cards.

Supports readback of firmware : On NovaLCT, the firmware of the receiving card can be read back and saved in the local PC.

Supports backup and readback of receiving card configuration file

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

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