Dragino RS485-LN Aims to Bridge the Gap Between RS485 Equipment and a LoRaWAN Network
Supporting both automated and interactive use, the RS485-LN can operate in LoRaWAN Class A or Class C mode on a range of frequency bands.
Shenzhen-based Dragino Tech has launched a convertor module designed to make it as as easy as possible to connect RS485 equipment to a LoRaWAN low-power long-range radio network: the Dragino RS485-LN.
"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," the company explains of its latest product. "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 minimising current consumption. It targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, smartphone detection, building automation, and so on."
The module supports LoRaWAN Class A and Class C protocols on the CN470/EU433/KR920/US915/EU868/AS923/AU915/IN865/RU864 frequency bands. User-defined commands are sent to connected RS485 devices, and the responses processed according to customisable rules; the processed data are then uploaded via the LoRaWAN network. Where user interaction is required, the RS485-LN can accept downlink commands which it will forward to the connected RS485 device, Dragino explains.
The Dragino RS485-LN is now available from the company's Tindie store, priced at $38.
