4G LTE RS-485 Modbus Gateway – Industrial IoT Connectivity Solution

The 4G LTE RS-485 Modbus Gateway (Model: LWM485) is an industrial IoT communication device designed to connect Modbus RTU-based equipment with cloud platforms through cellular connectivity. It enables remote data collection, monitoring, and communication between field devices and cloud-based applications.

Equipped with LTE Cat 1 connectivity, an RS-485 interface, and MQTT protocol support, this gateway helps integrate existing industrial equipment with modern IoT infrastructure. It collects data from compatible Modbus RTU devices and transfers it to cloud platforms using a customized JSON data format.

The gateway supports secure communication through TLS/SSL encryption, remote configuration, and Firmware Over-the-Air (FOTA) updates. Advanced data-handling capabilities, including byte swapping, data scaling, and custom register mapping, provide flexibility when integrating different industrial devices.

With a wide DC power input range and an industrial metal enclosure, the LWM485 is suitable for industrial automation, energy monitoring, smart manufacturing, building management, and remote asset monitoring applications.
