The JUTAI NED200 Industrial LED Display Driver is a high-performance integrated control core tailored for industrial and commercial intelligent scenarios. It integrates multi-protocol communication (RS485/Ethernet/MQTT), LED display control, voice broadcast, and relay linkage, breaking the silo of single-function devices. With rugged industrial-grade design, rich expansion interfaces, and standardized operation logic, it serves as a reliable "central hub" for information transmission and multi-device collaboration—ideal for parking lots, factories, commercial complexes, scenic areas, and smart parks.
- Rich wired interfaces: Ethernet for LAN long-distance connection, RS485 for industrial on-site communication (100m range), RS232 for legacy device docking, and TTL for short-distance linkage.
- IoT & cloud compatibility: Supports MQTT protocol, enabling seamless integration into cloud management platforms and IoT systems for remote monitoring and control.
- Plug-and-play adaptation: Quickly connects to existing management systems (parking lots, workshops, malls) without modifying hardware architecture, reducing transformation costs.
- High-load relay control: 2 industrial-grade relays can directly drive barriers, lights, equipment power supplies, and other devices, realizing automatic scenario linkage (e.g., door opening after QR code scanning).
- IO status monitoring: Reads dry contact signals from sensors, buttons, or switches, triggering preset actions (e.g., voice alarms, relay cutoff) when abnormal events occur.
- Safe and stable: Relays feature isolated output, with overcurrent protection for IO interfaces, adapting to harsh industrial environments.
- High-capacity voice storage: 8MB memory supports up to 256 voice files, with ID call mode for flexible playback (sequential/immediate play) of welcome messages, safety alerts, or operation confirmations.
- Dual-mode QR code interaction: Full-screen QR code for long-distance scanning (e.g., parking payment), 3-line QR code with text description for short-distance interaction (e.g., scenic spot guides), facilitating "screen-person" quick connection.
- On-site voice updates: Supports on-site voice file upgrades via tools, adapting to dynamic scenario needs without replacing hardware.
- 4-line independent management: Each line can display custom text, time, or notifications separately, meeting simultaneous transmission of multi-type information (e.g., navigation + promotions + time in malls).
- Global language support: Built-in font library for over 100 languages, adapting to cross-regional and multi-ethnic application scenarios without additional font configuration.
- Expandable display interfaces: Compatible with HUB75/HUB08 LED modules, expandable to 4 HUB12 interfaces via expansion boards, covering most mainstream LED display specifications.
- Extreme environment adaptation: Operates stably in -40°C ~ +85°C temperature range, suitable for outdoor or industrial workshops with large temperature fluctuations.
- Low operation threshold: All functions are controlled via standardized protocol commands, no complex programming required—technical teams can master it quickly.
- Minimal maintenance: No wearing parts; daily maintenance only requires checking communication lines and interfaces, reducing operation and maintenance workload.
- Industrial Workshops: Displays production data, safety guidelines, and equipment status in multi-language; IO interfaces detect equipment abnormalities, triggering voice alarms and cutting off power via relays to prevent failure expansion.
- Smart Parking Systems: Displays real-time parking availability and full-screen payment QR codes; relays control barriers to open automatically after payment, with voice broadcasts confirming "payment successful."
- Commercial Complexes: 4-line display for floor navigation, brand promotions, and real-time time; MQTT protocol enables remote content updates; QR codes link to coupons or membership registration.
- Smart Parks & Scenic Areas: Multi-language safety notices and 3-line QR codes for tour guides; visitors scan codes to register, triggering relays to open access control and play welcome voices.
- Access Control & Smart Buildings: Integrates with card readers via Wiegand interface; displays visitor information, plays welcome voices, and controls door access via relays, realizing intelligent entry management.
- Transportation Hubs: Provides multi-language schedules and directional guidance; Ethernet/MQTT supports remote content updates, ensuring real-time information transmission.
- All-in-One Integration: Combines communication, display control, voice broadcast, relay linkage, and QR code interaction, reducing system complexity and hardware costs.
- Industrial-Grade Durability: Wide temperature resistance, multiple protection mechanisms (reverse connection, overcurrent, ESD), ensuring 24/7 stable operation in harsh environments.
- Strong Expandability: Supports display interface expansion, voice file updates, and IO module addition, adapting to function upgrades without replacing the main device.
- Efficient Information Transmission: Multi-protocol + multi-language support enables fast information dissemination and cross-system collaboration, improving operational efficiency.
- Cost-Effective Operation: Standardized commands, minimal maintenance, and long service life lower long-term use costs for enterprises.
