Chapter 1 Introduction

The Moxa UC-71xx series of embedded computers (UC-7110, UC-7112, and UC-7112 Plus) are

mini, RISC-based, box-type computers that feature dual 10/100 Mbps Ethernet ports, two

RS-232/422/485 serial ports, and an ARM9 processor. The computers come with Linux

pre-installed. In addition, the UC-7112 Plus and UC-7112 have an internal SD socket for storage

expansion to offer high performance communication with unlimited storage in a super-compact,

palm-size box. The UC-71xx series of embedded computers are the right solution for embedded

applications that call for a small computer, but that can store large amounts of memory and

provide good computing performance.

In this chapter, we cover the following topics:

UC-7112 LX Plus UC-7112, UC-7110 User’s Manual Introduction

Overview

The UC-71xx series of mini, RISC-based communication platforms are ideal for embedded

applications. All three computers in the series (UC-7110, UC-7112, and UC-7112 Plus) come with

2 RS-232/422/485 serial ports and dual 10/100 Mbps Ethernet LAN ports to provide users with a

versatile communication platform.

The UC-71xx series computers use the MoxaARTARM9 192 MHz RISC CPU. Unlike the x86

CPU, which uses a CISC design, the ARM9’s RISC design architecture and modern

semiconductor technology provide these computers with a powerful computing engine and

communication functions, but without generating too much heat. The built-in NOR Flash ROM (8

MB for UC-7110/7112, 16 MB for UC-7112 Plus) and SDRAM (16 MB for UC-7110/7112, 32

MB for UC-7112 Plus) give you plenty of storage capacity, and the SD socket provides greater

flexibility for running various applications. The dual LAN ports built into the ARM9 allow the

UC-71xx computers to be used as communication platforms for basic data acquisition and protocol

conversion applications, and the two RS-232/422/485 serial ports allow you to connect a variety of

serial devices.

The UC-7110 and UC-7112 come with the µClinux operating system pre-installed, and the

UC-7112 Plus comes with the Linux operating system with MMU support pre-installed. Software

written for desktop PCs is easily ported to the UC-71xx computers with a GNU cross complier, so

that you will not need to spend time modifying existing software code. The operating system,

device drivers, and your own software can all be stored in the computers’Flash memory.
