I need a self-contained unit that lets me key a number on a small touch screen and see that exact value appear instantly on a freestanding LED numerical tower. The system should be true plug-and-play: once mains power is connected, it is ready without additional setup, drivers, or calibration. Key Requirements: • Input: A touch-screen number pad that accepts whole numbers (ideally up to four digits). • Display: An LED tower that shows the number in bright, easily readable digits; it must refresh instantly when entered or updated. • Form Factor: Bench-top or floor-standing, compact enough for shop-floor use, with one secure data link and durable construction. • Reliability: Stable operation for 8+ hours daily with clear status indicators (power, communication). Deliverables: 1. Fully assembled hardware (touch screen, controller, LED tower) delivered as ready-to-use. 2. Firmware/source files to allow future updates/reflashing. 3. Wiring diagram and a quick-start guide for ease of use. 4. Video proof or live demo showing successful plug-and-play functionality out-of-the-box.
