Overview

Maintain connectivity for distributed equipment with global Cat M1 cellular access, dual Ethernet, and serial interfaces for legacy devices. The ICR-3211B fits industrial IoT sites that need dependable remote access, protocol bridging, and straightforward deployment in space-constrained cabinets.

  • Global Cat M1 cellular connectivity
  • 2 x Ethernet ports
  • 1 x RS232 serial port
  • 1 x RS485 serial port
  • Industrial IoT router and gateway platform
  • Advantech ICR-3211B MPN
  • Designed for remote edge networking
  • Maintain remote connectivity using global Cat M1 cellular access

Keep remote infrastructure connected with a cellular gateway built for industrial IoT environments. The Advantech ICR-3211B combines global Cat M1 coverage with dual Ethernet ports and RS232/RS485 serial interfaces, giving operations teams a practical path to connect both modern IP devices and legacy field equipment.

This model is well suited to telemetry, remote monitoring, and machine-to-cloud deployments where wired broadband is unavailable or too costly to provision. Cat M1 support is designed for low-bandwidth, wide-area connectivity, while the serial ports help bridge older controllers, meters, and sensors into centralized management systems. Dual Ethernet adds flexibility for local network attachment, segmentation, or downstream device connectivity.

For teams standardizing on industrial gateways, the value is in reducing site complexity without sacrificing control. The ICR-3211B is a focused edge connectivity platform for applications that need reliable data transport, remote visibility, and a compact footprint for cabinet or panel installations. It is a strong fit when uptime, interface compatibility, and deployment simplicity matter more than consumer-style feature sets.

Ideal for

  • Connect remote utility meters and telemetry devices over cellular backhaul
  • Link legacy RS232 and RS485 controllers into a centralized monitoring system
  • Provide primary or backup connectivity for unmanned industrial sites
  • Support machine-to-cloud data collection in distributed IoT deployments
