4. Setup
Proper installation is crucial for the optimal performance of the A5s receiving card. Follow these steps carefully:
- Preparation: Ensure all power to the LED display cabinet is disconnected. Gather necessary tools, including anti-static wrist straps.
- Mounting: Securely mount the A5s receiving card into the designated slot within the LED display cabinet. Ensure it is firmly seated to prevent vibration.
- Power Connection: Connect the DC 3.8-5.5V power supply to the card's power input. Verify correct polarity.
- Data Connections:
- Connect the Ethernet cable from the sending card (or previous receiving card in a daisy chain) to one of the A5s's Ethernet ports (e.g., M1 or M2).
- If daisy-chaining, connect an Ethernet cable from the other Ethernet port of the A5s to the next receiving card.
- Connect the data cables from the A5s's JH1 and JH2 connectors to the LED modules. Refer to your LED module's documentation for correct pin assignments.
- Configuration:
- Once all physical connections are made, power on the LED display system.
- Use NovaStar's NovaLCT software on a connected computer to configure the receiving card parameters. This includes screen resolution, module type, data mapping, and calibration settings.
- Utilize the smart module support features for automatic calibration coefficient upload and module flash control.
- Testing: After configuration, perform a test pattern display to verify correct operation and image quality. Adjust settings as needed.
5. Operating Instructions
The A5s receiving card operates in conjunction with a NovaStar sending card and NovaLCT software. Most operational adjustments are made through the software interface.
- Power On/Off: The card powers on automatically with the LED display system. Ensure a stable power supply within the specified voltage range (DC 3.8-5.5V).
- Display Control: Use NovaLCT software to manage display parameters such as brightness, color temperature, gamma correction, and image scaling.
