The RS485-LN is a RS485 to LoRaWAN device. It converts the RS485 devices into LoRaWAN wireless network that change the IoT installation and reduce the installation/maintaining price. RS485-LN permits the user to monitor / control RS485 devices and reach extremely long ranges. It provides ultra-long range spread spectrum communication and high interference immunity while minimizing current consumption. It targets skilled wireless detector network applications like irrigation systems, smart metering, smart cities, smartphone detection, building automation, and so on. For data uplink: RS485-LN sends user-defined commands to RS485 devices and acquire the return from the RS485 devices. RS485-LN will process these returns per the user-define rule to induce the ultimate payload to transfer to LoRaWAN server. For data downlink: RS485-LN runs in LoRaWAN category C. once there downlink commands from LoRaWAN server, RS485-LN can forward the commands from LoRaWAN server to RS485 devices.
