Key Functional Advantages
1. Multi-Line Text & Real-Time Information Display
  • 4-line independent control: Each line can display different content (navigation, promotions, notices) simultaneously, meeting diverse information transmission needs without mutual interference.
  • Global language compatibility: Built-in font library covers over 100 languages, adapting to cross-regional and multi-ethnic scenarios without additional font configuration.
  • Customizable time overlay: Supports personalized time formats, automatically syncing real-time time without manual updates, ensuring information timeliness.
2. Dual-Mode Interactive QR Code
  • Flexible adaptation to distances: Full-screen QR code for long-distance scanning (e.g., parking payment, no need for car owners to get off), 3-line QR code with 4th-line text description for short-distance interaction (e.g., scenic spot guide, clear usage prompts).
  • Stable recognition guarantee: Automatically truncates excess characters to ensure QR code normal recognition; one-click command to exit QR code mode and restore original display content.
  • Wide application scope: Customizable QR code content (payment links, registration pages, guide maps), enabling fast "screen-person" connection.
3. Easy Integration & Low Operation Threshold
  • Rich communication interfaces: Ethernet for LAN long-distance management, RS485 for industrial on-site connection, RS232 for legacy device docking, adapting to various system architectures.
  • Standardized protocol control: All functions are implemented via standardized commands, no complex programming required—technical teams can master it quickly, reducing operation and maintenance costs.
  • Plug-and-play adaptation: Seamlessly connects to existing management systems (parking lots, malls, workshops) without modifying hardware architecture.
4. Peripheral Linkage & Stable Performance
  • Powerful relay control: 2 high-load relays can link barriers, lights, and equipment power supplies, realizing automatic scenario linkage (e.g., opening access control after QR code scanning).
  • Extreme environment adaptation: Operates stably in -40°C ~ +85°C temperature range, with ESD and pulse protection for communication ports, suitable for harsh industrial or outdoor environments.
  • Reliable data storage: Default display content, voice parameters, etc., are stored in flash memory and not lost after power failure.
5. Expandable Value-Added Functions
  • High-capacity voice broadcast: Stores up to 256 voice files, supporting sequential or immediate play for welcome messages, safety alerts, and operation confirmations.
  • On-site function upgrade: Supports on-site voice file updates and LED interface expansion (up to 4 HUB12 interfaces), adapting to dynamic scenario needs without replacing the main device.
Application Scenarios
  • Commercial Complexes: 4-line display for floor navigation, brand promotions, and real-time time; 3-line QR codes link to coupons or membership registration; multi-language support caters to international customers.
  • Smart Parking Lots: Full-screen parking payment QR codes, real-time parking availability display; relay control for barriers to open automatically after payment; voice broadcasts confirm "payment successful."
  • Scenic Areas & Parks: Multi-language safety guidelines and 3-line QR codes for tour guides (4th line: "Scan code to get detailed routes"); real-time time overlay helps tourists arrange schedules.
  • Industrial Workshops: 4-line display of production data, safety notices, and shift information; multi-language support adapts to diverse employee teams; IO interfaces detect equipment abnormalities and trigger voice alarms.
  • Public Transportation Hubs: Multi-language schedules, directional guidance, and real-time time; QR codes link to ticket purchase pages or route inquiries; remote content updates via Ethernet/MQTT.
  • Retail Stores: Display product promotions, discount information, and real-time time; QR codes direct to online stores or membership registration; voice broadcasts attract customer attention.
