USR-LG206-H-P RS232 RS485 To LoRa Converter 3500m Range Industrial Wireless

The USR-LG206-H-P is a high-performance serial RS232/RS485 to LoRa converter designed for industrial wireless communication over long distances. Supporting both point-to-point protocol and fixed-point transmitting mode, it enables reliable and stable data transmission between serial devices and LoRa networks, making it ideal for automation, remote monitoring, smart metering, and IoT applications.

Operating in the 803-930 MHz frequency band, this module provides robust wireless connectivity with a transmission range of up to 3500 meters under open area conditions, with clear weather, 20 dBm transmitting power, 5 dBi antenna gain, and antenna height above 2 meters. The high receiving sensitivity of -138.5 dBm @ 0.268 Kbps ensures reliable signal reception even in challenging environments.

The USR-LG206-H-P supports both RS232 and RS485 interfaces, with serial baud rates from 1200 bps to 115200 bps, providing flexible integration with a wide range of industrial devices such as PLCs, sensors, meters, and controllers. Its compact design operates efficiently across a wide voltage range of 5-36 V DC, with a low working current of 45 mA @ 12 V during transmission and 12 mA in standby mode.

Designed for harsh industrial environments, the module supports operating temperatures from -30 C to +80 C and storage temperatures from -45 C to +90 C, with relative humidity ranges from 10% to 90%, ensuring reliable performance in extreme conditions. An SMA antenna interface allows easy connection to external antennas for optimized range and signal quality.
