User Manual for LoRaWAN End Nodes - RS485-LN – RS485 to LoRaWAN Converter User Manual
RS485-LN allows user to monitor / control RS485 devices and reach extremely long ranges. It provides ultra-
long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
It targets professional wireless sensor network applications such as 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 gets the return from the RS485
devices. RS485-LN will process these returns according to user-define rules to get the final payload and upload to
LoRaWAN server.
For data downlink, RS485-LN runs in LoRaWAN Class C. When there downlink commands from LoRaWAN
server, RS485-LN will forward the commands from LoRaWAN server to RS485 devices.
