This feature allows you to actively monitor the device status and screen status, ensuring that any faults or alarms are promptly detected and reported. With real-time monitoring, you can take proactive measures to address issues and maintain the optimal functionality of your LED display.

Flexible Working Modes: All-In-One and Send-Only Controller

Furthermore, the KU20 offers two versatile working modes to suit different application requirements. In the All-In-One Controller mode, users have access to advanced features such as layer management and scaling functions. This mode allows for comprehensive control over the display content and enables seamless integration with the VMP software. By connecting the KU20 to the VMP software, you can enjoy easy and convenient operations, as well as smart device management. Alternatively, the Send-Only Controller mode provides a simplified setup for applications where basic display control is sufficient.

Comprehensive Control and Monitoring: VMP Software Integration

Take full control of your LED display system with the KU20’s integration with the Vision Management Platform (VMP) software. The VMP software enables easy and convenient operation and management of the KU20, offering comprehensive control over various parameters and settings. Monitor the status of devices and screens, receive active fault and alarm notifications, and streamline your control operations with the intuitive interface of the VMP software.

Effortless Cascading: Simplified Networking

Simplify networking and cascading control with the KU20’s effortless cascading capability. The Gigabit Ethernet control ports support the TCP/IP protocol, eliminating the need for additional switches or routers. Deploy multiple devices on the same LAN without hassle, thanks to the KU20’s built-in network switching function.

Function Limitations: Optimal Compatibility

To optimize performance, consider the KU20’s functional limitations. The Frame Rate Adaptive function is compatible when paired with the A10s Pro receiving card. Supported driver ICs include ICND2055, ICND2065, MBI5253A, MBI5253B, MBI5754B, MBI5264, and CFD555. To enable the Full Grayscale Calibration function, the KU20 must be used in conjunction with the A10s Pro receiving card. It’s important to note that the .ncp file generated by the Cabinet Tool from NovaStar must be utilized for optimal performance.
