UC-8100-ME-T Series

The UC-8100-ME-T computing platform is designed for embedded
data acquisition applications. The computer comes with two RS-
232/422/485 serial ports and dual 10/100 Mbps Ethernet LAN ports, as
well as a Mini PCIe socket to support cellular modules. These versatile
capabilities let users efficiently adapt the UC-8100-ME-T to a variety of
complex communications solutions.
The UC-8100-ME-T is built around a Cortex-A8 RISC processor that
has been optimized for use in energy monitoring systems, but is
widely applicable to a variety of industrial solutions. With flexible
interfacing options, this tiny embedded computer is a reliable and
secure gateway for data acquisition and processing at field sites as
well as a useful communications platform for many other large-scale
Wide temperature LTE-enabled models are available for extended
temperature applications. All units are thoroughly tested in a testing
chamber, guaranteeing that the LTE-enabled computing platforms are
suitable for wide-temperature application.

Linux Board Support Packages (BSP) • GCC C/C++ cross development tool chain
• Bootloader/ Kernel/ filesystem
Cellular Networking • WVDIAL: Point-to-Point Protocol dialer that dials a modem and starts pppd to connect to the Internet.
• QMI (Qualcomm MSM Interface): Glib-based library for talking to WWAN modems and devices that speak the Qualcomm MSM Interface (QMI) protocol.
• MODBUS: Software library to send/receive data according to the Modbus protocol. This library is written in C and supports RTU (serial) and TCP (Ethernet) communications.
• Watchdog: Features a hardware function to trigger system reset in a user specified time interval (Linux standard API).
Cybersecurity •SUDO Mechanism: Sudo (short for super-user do) is a program designed to let system administrators allow some users to execute certain commands as the root user (or another user). The root user account is disabled by default. The basic philosophy is to give as few privileges as possible but still allow people to get their work.
• Security Update of Existing Software Packages: All software packages installed on the UC-8100-ME-T can be automatically updated using Debian Linux’s Advanced Packaging Tool (APT) server or Moxa’s server.
• USB Protection: Provides a mechanism for disabling USB function to avoid USB stick malware attacks.
• SD Write Protection: Provides a mechanism for disabling write permission to the microSD memory card plugged in directly into the card slot, or which is part of an extended storage system.
