USR-LG207 is a LoRa point-to-point, high-power data transmission terminal, which realizes RS232/485 to LoRa function. It supports 8000 meters of long-distance transmission and has strong anti-interference ability; Support point-to-point communication + fixed-point sending; It has a retransmission mechanism to reduce the packet loss rate and enhance the stability of data transmission. It supports 4-level ESD, 3-level power surge protection, 3-level RS485 surge protection, hardware watchdog and other multiple protections.
