Moxa’s UC-3100 Series computers can be used as edge-field smart gateways for data pre-processing and transmission, as well as for other embedded data-acquisition applications. The UC-3100 Series includes three models, each supporting different wireless options and protocols. The UC-3100’s advanced heat dissipation design makes it suitable for use in temperatures ranging from -30 to 70°C. In fact, the Wi-Fi and LTE connections can be used simultaneously in both cold and hot environments, allowing you to maximize your “data pre-processing” and “data transmission” capability in most harsh environments.

The UC-3100 is more than just a hardware solution. In order to offer a better user experience with a Moxa Arm-based computer, the UC-3100 supports the following software features, allowing you to use the most suitable configuration for your application.

  • High VPN performance; greater than 70 Mbps Ethernet throughput with AES-256 encryption

  • Robust file system to prevent the system from being bricked due to a firmware upgrade failure

  • Cybersecurity auto-configuration system based on IEC 62443

  • Real COM mode to provide a control interface to Moxa’s NPort products

In addition, Moxa provides 10 years of Linux OS support from Moxa’s customer support engineers. With a new version of the Debian repository released on average every 2 to 3 years, long-term Linux OS support helps you create a reliable solution that will be supported now and long into the future.
