Chapter 1 Introduction
The UC-7122/7124 are pocket size embedded computers with 2 or 4 serial ports, dual 10/100
Mbps Ethernet, an SD socket, and a USB 2.0 host port. The UC-7122/7124 are ideal for front-end
device monitoring, data acquisition, and protocol conversion. Wide temperature models are also
available to provide reliable performance in harsh operating environments.
The RISC-based UC-7122/7124 embedded computers come with the Windows® CE operating
system pre-installed. Microsoft® Windows® CE 5.0 is an open, scalable, 32-bit operating system
that allows users to build a wide range of innovative, small footprint devices. A typical Windows®
CE-based device is designed for a specific use, and often runs disconnected from other computers,
or distributed as a front-end to a centralized host. Examples include enterprise tools, such as
industrial controllers, communications hubs, point-of-sale terminals, and display devices, such as
HMI, advertisement appliances, and interactive panels.
