DH418

Receiving Card

DH418 is a cost-effective receiving card launched by Nova Technology. A single card can load up to 256×256 pixels and supports up to 16 groups of RGB parallel data. use

8 standard HUB75 interfaces, with high stability and high reliability, are suitable for building in a variety of environments.

The hardware design and software design of DH418 fully consider user deployment, operation and maintenance scenarios, making deployment easier, running more stable, and maintaining more efficient.

Features

Improve display effect
- Support point-by-point brightness and chromaticity correction
Cooperate with NovaLCT and NovaCLB to correct the brightness and chromaticity of each lamp point.
- Quick bright and dark line adjustment
Quickly adjust the bright and dark lines on NovaLCT to eliminate the gaps between the light board and the light board, and the box body.
- 3D function
    Cooperate with the controller that supports 3D function, turn on the 3D function on NovaLCT or the operation panel of the controller, and set the 3D parameters to make the display screen display 3D effect.
    With load:
    − 192×256 (PWM IC)
    − 176×256 (General IC)

Improve maintainability
- Mapping function
After the Mapping function is enabled on NovaLCT, the receiving card number and network port information will be displayed on the target cabinet, and the location and wiring method of the receiving card can be clearly obtained.
- Receiving card pre-stored picture settings
On NovaLCT, you can set the specified picture as the startup picture of the display, the picture when the network cable is disconnected or there is no video source signal.
Save two copies of receiving card configuration parameters on the receiving card through NovaLCT, one of which is used as a backup parameter.
- Dual program backup
- Temperature and voltage monitoring It can monitor its own temperature and voltage without other peripherals. You can view the temperature and voltage of the receiving card on NovaLCT.
- LCD module
Support the universal 5pin LCD module of Nova Technology. Used to display the temperature, voltage, single running time and total running time of the receiving card.
- Bit error rate monitoring
With NovaLCT (V5.2.0 and above), when communicating between receiving cards, monitor the data packet loss on the transmission link.
- Firmware program readback
On NovaLCT (V5.2.0 and above), the firmware program of the receiving card can be read back and saved locally.
- Configuration parameter readback
On NovaLCT, the configuration parameters of the receiving card can be read back and saved locally Improve reliability
- Loop backup
Increase the reliability of the serial connection of receiving cards through the main-standby redundancy mechanism. In the main and standby serial lines, when one of the lines fails, the other line will work immediately to ensure that the display screen works normally.
- Double backup of configuration parameters
The receiving card saves two copies of the application program when it leaves the factory to prevent the upgrade from being stuck due to abnormal program update.

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:
