Overview
The Inventory Master’s LoRaWAN RS-485 to Wireless data converter is a DTU (Data Transfer Unit) device that converts the RS-485 bus to wireless data. Sub models achieve RS-485 data to LTE (Cat.1 or Cat. 4), private LoRa, standard LoRaWAN, Ethernet, etc. communications method. This is a highly reliable DTU device that can be used in industrial scenarios, directly installed on rack rails, and provide a method that makes previous devices realize IoT evolution. All these series come with an easy configuration function, which can directly manage and configure options and parameters in the LAN.
Features
