DH426

Receiving Card

DH426 is a universal receiving card launched by Nova Technology. The single card can load up to 512×384 pixels (NovaLCT is V5.3.0 and above). It supports brightness correction, fast bright and dark line adjustment, 3D, RGB independent Gmma adjustment and other functions. Improve the screen display effect and enhance the user experience.

 

DH426 uses 16 standard UB75E interfaces for communication, has high stability, supports up to 32 groups of RGB parallel data, and is suitable for the construction of a variety of on-site environments.

Features

  • Brightness correction
  • Cooperate with NovaLCT and Nova CLB to correct the brightness of each lamp point, so that the brightness of the entire screen is highly uniform and consistent, and the image quality of the display is improved.
  • Quick adjustment of bright and dark lines Adjust the bright and dark lines caused by module splicing and cabinet splicing to improve the visual abruptness caused by bright and dark lines. The adjustment process takes effect immediately, which is easy to use.
  • 3D function Cooperate with sending card that supports 3D function to output 3D picture.
  • RGB independent Gamma adjustment Cooperate with sending cards that support RGB independent Gamma adjustment and NovaLCT (V5.20 and above). By adjusting the “Red Gamma Green Gamma” and “Blue Gamma” respectively, it can effectively control the low gray unevenness of the display, white balance drift and other issues. , Make the picture more real.

 

Improve maintainability

  • Mapping function The receiving card number and network port information are displayed on the box, and the location and wiring method of the receiving card can be clearly obtained.
  • Temporary measurement of temperature and voltage Monitor the temperature and voltage of the receiving card itself, without other peripherals.
  • Error monitoring Detect the communication quality of the network port of the receiving card, record the number of error packets, and help eliminate hidden network communication hazards. NovaLCT must be V5.2.0 and above.
  • Read back the firmware program Read back the firmware program of the receiving card and save it locally. NovaLCT must be V5.2.0 and above.
  • Read back configuration parameters Read back the configuration parameters of the receiving card and save them locally.

Flashing every 1s:
No sending card mode: The receiving card works normally, the sending card is not connected, the network cable is connected normally, and there is a video source input.
Flashing every 0.5s:
Sending card mode: The receiving card and the sending card work normally, the network cable is connected, and there is a video source input.
Flashing every 3s: The receiving card is working normally, but the network cable connection is abnormal.
Flash 3 times at an interval of 3s: The receiving card is working normally, the network cable is connected normally, and there is no video source input.
Fast flashing every 0.2s: The program fails to load in the normal working state and enters the backup working state.

 

Constant light:
Always on after power supply.
