USR-LG206-H-P Serial RS232 RS485 to LoRa Converter Server Device (Point to Point) 3500 Meters Transmission Distance High Sensitivity Air Waking Up for Smart Metering Oil Field Agriculture

USR-LG206-P is half duplex Serial to LoRa covnerter which supports point-to-point protoco. LG206 transmits/receives data by serial and it can realize one-to-one or one-to-many communication. LG206-P will encrypt data to make data transmission more secure. User can enter AT command mode and use command: AT+KEY to set encryption word RSSI indication can query RSSI of both sides of communication to provide a reference for assessing communication quality.? Features Adopt LoRa point-to-point protocol. Support fixed-point transmitting mode. Data encryption transmission. Support RS232/RS485 interface. Maximum communication distance: 2300m. (Test in an empty area, under the 20 dBm transmitting power and 3.5dBi antenna gain) Receiving sensitivity: -138.5dBm. Support AT command mode and setup software based on AT command mode. Support hardware watchdog. 5~36V power supply. Support ESD protection. Support power supply anti surge. Support RS485 anti surge. USR-LG206-P supports three work modes:? AT command mode Transparent transmission mode Fixed-point transmitting mode Note: Length of single data package can?t exceed 252 bytes in all three work modes, otherwise the package will be discarded.
