ICR-3231 overview


The ICR-3231 LTE gateway places intelligence at the network edge using ARM's Cortex A8 1GHz processor and 512MB onboard system memory and 4GB eMMC storage in pSLC mode for a long-lifetime and critical industrial applications. Allocating 1.3GB of system storage is for customer SW applications and data. By utilising LTE Cat 4 with upload speeds of up to 50Mbps and download speeds of 150Mbps this gateway router has ample bandwidth for CCTV and other bandwidth-intensive applications.

Additionally to its two independent or switched Ethernet ports, one RS-232 and one RS-485 port the ICR-3231 has built-in digital I/O connectivity, backup real-time clock and sleep mode support. The device has two SIM readers for carrier failover redundancy.

With open Linux platform and wide possibilities of programming customer SW applications in Python, C/C++ or browser-based flow editor Node-RED the ICR-3200 offers a real open development platform for Industrial IoT applications.
