NED200 Multi Functional Controller for LED Signs Advertising Boards and Interactive Displays

Core Technical Parameters

Key Functional Advantages

1. Flexible Display Control for Advertising & Information

• 4-line independent management: Each line can display different advertising content, promotions, or public notices simultaneously, meeting multi-information transmission needs for LED signs and advertising boards.
• Multi-language universal: Built-in font library covers over 100 languages, adapting to cross-regional and multi-ethnic advertising scenarios without additional font configuration.
• Customizable time overlay: Supports personalized time formats, automatically syncing real-time time to be displayed on advertising boards or information signs, enhancing content timeliness.

2. Interactive QR Code for "Advertising + Interaction"

• Dual-mode adaptation: Full-screen QR code for long-distance scanning (e.g., mall promotion links, parking payment), 3-line QR code with 4th-line text description (e.g., "Scan code to get coupons") for short-distance interaction, improving user participation.
• Stable recognition guarantee: Automatically truncates excess characters to ensure QR code normal recognition; one-click command to exit QR code mode and restore original advertising content.
• Wide application scope: Customizable QR code content (promotion pages, membership registration, product details), realizing seamless connection between offline advertising and online services.

3. Voice Broadcast to Enhance Advertising Impact

• High-capacity voice storage: 8MB memory supports up to 256 voice files, which can be advertising slogans, product introductions, or welcome messages.
• Flexible playback modes: Sequential play (for continuous advertising broadcasts) or immediate play (for real-time interactive prompts), enriching the expression form of LED advertising.
• On-site update capability: Supports on-site voice file upgrades via tools, adapting to dynamic advertising content changes without replacing hardware.

4. Rich Interfaces for Universal Integration

• Multi-protocol communication: Seamlessly docks with RS485 (short-distance on-site control), Ethernet (LAN long-distance management), and MQTT (cloud-based advertising content push), adapting to diverse application architectures.
• Versatile port configuration: 2x RS232 for legacy device docking, TTL for short-distance linkage, and Wiegand interface for access control + advertising integration (e.g., shopping mall member exclusive advertising).
• Plug-and-play adaptation: Quickly connects to existing advertising management systems without modifying hardware architecture, reducing deployment costs.

5. Peripheral Linkage & Industrial-Grade Stability

• Powerful relay control: 2 high-load relays can link lights, barriers, or audio equipment, realizing automatic linkage (e.g., turning on advertising lights when someone approaches, triggered by sensors).
• IO status monitoring: Reads sensor or button signals to trigger preset actions (e.g., playing promotional voices when a pedestrian is detected, switching advertising content).
• Extreme environment adaptation: Operates stably in -40°C ~ +85°C temperature range, with multiple protections (reverse connection, overcurrent, ESD), suitable for outdoor advertising boards and harsh commercial environments.
