Introduction

The UC-2100 Series computing platform is designed for embedded data acquisition and processing applications. The computer comes with up to two software selectable RS-232/422/485 full-signal serial ports and single or dual Ethernet ports. This palm-sized series of Arm-based computing platforms includes a variety of models for a wide range of interface requirements, such as single or dual serial and Ethernet ports, Gigabit Ethernet, and wireless connections. These versatile communication capabilities allow users to efficiently adapt the UC‑2100 for a variety of complex communications solutions. The UC-2100 Series has a built-in Cortex-A8 Arm-based processor that has been optimized for a variety of industrial solutions. With its flexible interface options, this tiny embedded computer is a reliable and secure gateway for data acquisition and processing at field sites and is a useful communication platform for many other large-scale deployments. Models designed for wide temperature applications are available for use in extreme environments such as those found in the oil and gas industry. Furthermore, all models use the Moxa Industrial Linux platform, which provides optimized software features and long-term support.
