Trax10156-RS485/Modbus LoRaWAN Converter
Trax10156 RS485 Modbus to LoRaWAN converts the RS485 devices into LoRaWAN wireless network, which simplifies the IoT installation and reduces the installation/maintaining cost. Allows to monitor/control RS485 devices, 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 and building automation.
Description
For data uplink, Trax10156 sends user-defined commands to RS485 devices and gets the return from the RS485 devices. Converter will process these returns according to user-defined rules to get the final payload and upload to LoRaWAN server. For data downlink, converter runs in LoRaWAN Class C, when there is a downlink commands from LoRaWAN server, converter will forward the commands from LoRaWAN server to RS485 devices.
