The Dragino RS485-LN is a RS485 to LoRaWAN Converter. It converts the RS485 signal into
LoRaWAN wireless signal which simplify the IoT installation and reduce the
installation/maintaining cost.
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.
