Common Pain Points
Traditional wired serial communication is limited by high cabling costs, distance constraints, and complex wiring, making deployment difficult in remote or large-scale sites (farms, factories, pipelines). Wireless alternatives like WiFi/Zigbee suffer from short range, weak interference resistance, and high power consumption. In harsh industrial environments, extreme temperatures, dust, and electromagnetic interference often cause device failures, data loss, or downtime. Data security risks are high without encryption, making interception easy. Upgrading legacy PLCs/sensors requires complex modifications, severely hindering low-cost, reliable deployment of Industrial IoT and remote monitoring.
Solution & Core Features
1.Ultra-Compact Industrial Design — Extremely small size (74.5 × 22.5 × 16.2 mm), rugged corrosion-resistant metal housing with IP30 protection, supports DIN rail or ear-hook integrated mounting, tool-free push-in terminals for fast adaptation to confined spaces or harsh environments.
2.Ultra-Long-Range Stable Transmission — Powered by LoRa spread-spectrum technology, achieves up to 5 km communication distance in open areas (22 dBm TX power + 3 dBi antenna gain, installation height ≥ 2 m), with strong anti-interference and excellent penetration, ideal for large-scale, base-station-free scenarios.
3.Multi-Interface & Flexible Modes — Supports RS232/RS485/TTL serial ports (1200–460800 bps baud rate), point-to-point mode (dynamically adjustable target address/channel) and broadcast transmission; supports Modbus TCP protocol, transparent passthrough + encrypted transmission (customizable key — only devices with the same key can communicate).
4.Industrial-Grade Durability & High Reliability — 9–36 V wide voltage input (reverse polarity protection), full industrial temperature range -40°C to +85°C; dual watchdog (hardware + software) prevents crashes, ESD Level 3 protection, EMI resistance, metal anti-corrosion shell ensure 24/7 uninterrupted stable operation.
5.Secure & Plug-and-Play — Encrypted data transmission enhances security; AT command configuration and firmware upgrade via serial port, quick deployment without complex programming; external LoRa antenna interface improves performance in weak-signal areas.
