The Dragino RS485-LN is a RS485 to LoRaWAN Converter.
It converts the RS485 devices into LoRaWAN wireless network which
simplify the IoT installation and reduce the installation/maintaining
cost.
RS485-LN allows the 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,
building automation, and so on.
For data uplink:
RS485-LN sends user-defined commands to RS485 devices and get the
return from the RS485 devices. RS485-LN will process these returns
according to the user-define rule to get the final payload to 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.
