Plug-and-Play · Flexible Expansion Full-Interface Strip Bar Screen with USB/Ethernet/RJ45: Compatible with Barcode Scanners, Sensors, and Other Peripherals
In the wave of smart commerce and industrial connectivity, Guangzhou Ruiguan Electronic Equipment's full-interface Strip Bar Screen has become a core hub for connecting smart peripherals and building scenario-specific solutions, thanks to its rich physical interfaces and plug-and-play compatibility. Supporting full-function interfaces such as USB, Ethernet, and RJ45, this series can adapt to barcode scanners, sensors, printers, and other devices without complex debugging, providing efficient and flexible display terminals for retail, government, industrial, and other scenarios.
I. Full-Function Interface Layout: One-Stop Meeting Diverse Needs
The Strip Bar Screen is equipped with 9 core interfaces covering all scenarios such as data transmission, device expansion, and audio/video output:
Data Interaction:
USB OTG×1: Supports direct reading of content from external USB drives (e.g., JPG images, MP4 videos), automatically recognizing and looping playback after insertion, suitable for temporary scenarios like pop-up stores and exhibitions;
USB HOST×1: Connects to USB peripherals such as keyboards/mice, barcode scanners, and cameras. For example, in smart retail, customers can scan product barcodes with a USB barcode scanner, and the Strip Bar Screen instantly displays prices, inventory, and promotional information.

Network and Storage:

RJ45 Ethernet Port×1: 10/100Mbps Ethernet interface for stable access to enterprise intranets, supporting remote cluster management;

Micro SD Card Slot×1: Supports up to 64GB storage expansion, pre-storing advertising materials or industry data for normal playback in offline environments.

Audio/Video and Power Supply:

HDMI OUT×1: Supports 1080P HD output, synchronizing content to large-screen displays or projectors;

LINE OUT×1: Connects to external speakers to enhance advertising audio reach;

DC 12V×1: Wide voltage adaptation (AC 90-240V), globally universal.

II. Plug-and-Play Ecosystem: Reducing Technical Barriers and Costs

Driver-Free Compatibility: Supports plug-and-play for mainstream peripherals without installing drivers:

Retail Scenarios: Connects to 1D/2D barcode scanners via USB HOST to achieve a "scan-display-pay" closed loop. Pilot data from a chain supermarket showed that after introducing the Strip Bar Screen, the usage rate of customer self-service product information queries increased by 60%, and cashier consultation pressure decreased by 40%;

Industrial Scenarios: Accesses PLC control systems via RJ45 to display real-time equipment operation parameters (e.g., temperature, rotation speed), replacing traditional LED digital screens with more intuitive interfaces.

Industry Software Adaptation: Compatible with mainstream digital signage software like Hefeng and Mantianxing, supporting one-click APK installation via USB or network. For example, in government halls, it can access queue number systems to display real-time information like "Current Service Window: No. 3" without additional development.

III. Flexible Expansion Capability: Customized Scenario Solutions

Serial Device Integration: Supports external RS232/RS485 serial modules, adapting to industrial sensors (e.g., temperature/humidity monitoring), printers (e.g., receipt printing), card readers (e.g., public transport card recognition), and other devices. For example, in smart buildings, the Strip Bar Screen connects to human infrared sensors via serial ports to automatically play guidance videos when people approach.

Multi-Device Linkage: Through a combination of USB and Ethernet ports, it can simultaneously connect to barcode scanners and cloud servers, enabling intelligent interaction of "local scan triggering + cloud data calling." In a beauty store case, when customers scanned product packaging QR codes, the Strip Bar Screen retrieved usage tutorial videos from the cloud, increasing conversion rates by 35%.

IV. Technical Parameters and Reliability

Interface Type	Function Description	Typical Application
USB OTG	External USB drives, hot-swappable	Temporary advertising content updates
USB HOST	Barcode scanners, keyboards/mice, cameras	Retail self-service queries, industrial control
RJ45 Ethernet	Wired Ethernet connection, remote management	Cluster control for chain stores
