Keywords: KT819, Industrial Signal Converter, RGB to VGA, Composite Video to VGA, RGBS Converter, Kongto Technology
Product Overview
The KT819 is a next-generation multi-protocol industrial video signal converter developed by Kongto Technology. Supporting automatic VGA/RGBS dual-input detection, it also features RGB signal and composite video (CVBS) signal conversion capabilities, outputting standard VGA signals. Designed specifically for industrial environments with wide temperature operation and metal housing with EMI shielding, it meets diverse display interface upgrade needs for legacy CNC systems and industrial equipment.

How Dual-Input Auto-Detection Works
The core advantage of KT819 is its intelligent dual-input interface design. It can simultaneously connect two different signal sources, and the device automatically determines which interface has an active signal input and switches to the corresponding mode:
- VGA Pass-through Mode: When the VGA input detects a valid VGA signal (typically from modern devices), the converter directly passes the signal through to the VGA output with zero latency.
- RGBS Conversion Mode: When the RGBS input detects a separate sync RGB signal (from legacy CNC equipment), the converter converts the RGBS signal to standard VGA timing and outputs it.
- CVBS Mode: When composite video input detects a PAL/NTSC signal, it automatically decodes and up-converts to VGA output (this mode is optional).
Typical Applications
- Dual Display Requirements for Legacy CNC Equipment: One KT819 can simultaneously connect old and new display devices with automatic switching —no manual intervention needed. Ideal for sites requiring simultaneous monitoring of both legacy and modern systems.
- Industrial Testing Equipment Interface Unification: Convert testing equipment outputs with different interface standards (RGBS/CVBS/VGA) to unified VGA for central monitoring systems, reducing equipment procurement costs.
- On-Site Equipment Debugging: Portable debugging devices typically output VGA while fixed monitoring equipment may use legacy RGBS interfaces. KT819's dual-input design solves both needs with one device.
- Education and Demonstration Environments: Convert CVBS or RGBS output from legacy lab equipment to VGA for connection to modern projectors or monitors, without replacing original educational equipment.
Product Highlights
- VGA/RGBS Dual-Input Auto-Detection: A rare dual-input automatic switching design in the industry. One device is compatible with multiple signal sources, significantly reducing spare parts inventory.
- Native RGBS Support: Perfectly compatible with industrial equipment from the CGA/EGA era. No additional signal separator required.
- Ultra-Low Power Design: Full-load power consumption does not exceed 1.8W, suitable for 24V DC-powered industrial sites.
- Industrial EMI Shielding: Metal housing design effectively resists electromagnetic interference from variable frequency drives, motor drives, and other equipment.
- Wide Temperature Design: Operating temperature range from -20掳C to +70掳C, adapting to northern winter workshops and southern summer high-temperature environments.
