Key Functional Advantages
1. 100+ Languages & Flexible Display Control
- Global language compatibility: Built-in font library covers over 100 languages, adapting to cross-regional and multi-ethnic application scenarios without additional font configuration.
- 4-line independent management: Each line displays custom content (text, time) separately, meeting simultaneous transmission of navigation, promotion, and notification information.
- Customizable time overlay: Supports personalized time formats, automatically syncing real-time time without manual updates.
2. Rich Communication Interfaces for Universal Integration
- Multi-protocol support: Seamlessly docks with RS485 (short-distance industrial communication), Ethernet (LAN long-distance connection), and MQTT (IoT/cloud integration), adapting to diverse system architectures.
- Versatile port configuration: 2x RS232 for legacy devices, TTL for short-distance linkage, and Wiegand interface for direct connection to access control devices (card readers/biometrics).
- Plug-and-play integration: Quickly connects to existing management systems (parking lots, workshops, malls) without modifying hardware architecture.
3. Interactive QR Code & Voice Broadcast
- Dual-mode QR code: Full-screen mode for long-distance scanning (e.g., parking payment), 3-line mode with text description for short-distance interaction (e.g., scenic spot guides).
- High-capacity voice storage: Stores up to 256 voice files, supporting sequential or immediate play for welcome messages, safety alerts, and operation confirmations.
- Seamless mode switching: One-click command to exit QR code mode and restore original display content.
4. Peripheral Linkage & Stable Performance
- Powerful relay control: 2 high-load relays link barriers, lights, and equipment power supplies, enabling automatic scenario linkage.
- IO status monitoring: Reads sensor/button signals to trigger preset actions (e.g., equipment alarm, voice broadcast) based on external events.
- Extreme environment adaptation: Operates in -40°C to +85°C temperatures, with ESD/pulse protection for communication ports, suitable for harsh industrial/outdoor environments.
5. Easy Use & Cost-Effective Expansion
- Low operation threshold: All functions controlled via standardized protocol commands, no complex programming required.
- On-site function upgrade: Supports on-site voice file updates and IO interface expansion modules, avoiding main device replacement.
- Minimal maintenance: No wearing parts; daily maintenance only requires checking communication lines and interfaces.
Application Scenarios
- Commercial Complexes: 4-line display for floor navigation, brand promotions, and real-time time; multi-language support caters to international customers; QR codes link to coupons.
- Smart Parking Lots: Full-screen payment QR codes, real-time parking availability display; relay control for barriers; voice broadcasts confirm payment success.
- Industrial Workshops: Displays production data and safety guidelines in multi-language; IO interfaces detect equipment abnormalities, triggering voice alarms and power cutoff via relays.
- Scenic Areas & Public Spaces: Multi-language safety notices and 3-line QR codes for tour guides; voice welcomes visitors after code scanning.
