Introduction

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 -40 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.

In addition, TPM v2.0 uses a hardware chip to boost data security,

making it highly unlikely that hackers will be able to steal your data,

either remotely or locally.

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 based on your particular 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 interruption

• Cybersecurity auto-config system compliant with IEC 62443 lv.2

• Real COM mode to provide a control interface with 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.
