Dragino RS485-LN RS485 to LoRaWAN Converter 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, smartphone detection, building automation, and so on.
For data uplink: RS485-LN RS485 to LoRaWAN Converter Convertersends user-defined commands to RS485 devices and gets 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 the LoRaWAN server.For data downlink: RS485-LN runs in LoRaWAN Class C. When there downlink commands from the LoRaWAN server, RS485-LN will forward the commands from the LoRaWAN server to RS485 devices.
- LoRaWAN Class A & Class C protocol (default Class C)
- Frequency Bands: CN470/EU433/KR920/US915 EU868/AS923/AU915/IN865/RU864
- AT Commands to change parameters
- Remote configure parameters via LoRa Downlink
- Firmware upgradable via program port
- Support multiply RS485 devices by flexible rules
- Support modbus protocol devices
- Uplink on periodically or polling
- Downlink to send RS485 commands
