Product Datasheet

Introduction

The Robustel Smart Industrial IoT Gateway M1200 is a compact cellular gateway compatible with GSM/GPRS/EDGE/UMTS/WCDMA/HSDPA/HSUPA/HSPA+/FDD LTE/TDD LTE/Cat M1/Cat NB1 networks. This dual-SIM gateway enables remote data transmission from local serial ports and I/O, supporting interfaces such as RS-232, RS-485, and mini-USB. The M1200 provides users with stable network connectivity and reliable data transmission, designed to meet the demands of industrial applications with its standards-compliant design. As a versatile gateway, it is applicable in various scenarios, including energy, transportation, agriculture, and more.

The Robustel Cloud Manager Service (RCMS) is a unified cloud-based platform designed for real-time monitoring and centralized management of industrial IoT devices. Fully compatible with Robustel routers and gateways, RCMS delivers an interactive geospatial dashboard that enables users to visualize device locations and track critical metrics such as data usage, signal strength, and network status. To ensure seamless operations, the platform facilitates over-the-air (OTA) updates for firmware, configurations, and applications, minimizing downtime while optimizing system performance.
