Chapter 1 Introduction

The Moxa UC-7101 series of embedded computers are mini, RISC-based, box-type computers that

feature 10/100 Mbps Ethernet ports, RS-232/422/485 serial ports, and an ARM9 processor. The

computers come with Linux pre-installed. In addition, the UC-7101 has an internal SD socket for

storage expansion to offer high performance communication with unlimited storage in a

super-compact, palm-size box. The UC-7101 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-7101 Hardware User’s Manual Introduction

Overview

The UC-7101 series of mini, RISC-based communication platforms are ideal for embedded

applications. All computers in the series come with RS-232/422/485 serial ports and 10/100 Mbps

Ethernet LAN ports to provide users with a versatile communication platform.

The UC-7101 series computers use the Moxa ART ARM9 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-7101) and SDRAM (16 MB for UC-7101) give you plenty of storage capacity, and the

SD socket provides greater flexibility for running various applications. The LAN ports built into

the ARM9 allow the UC-7101 computers to be used as communication platform for basic data

acquisition and protocol conversion applications, and the RS-232/422/485 serial ports allow you to

connect a variety of serial devices.

The UC-7101 comes with the µClinux operating system pre-installed. Software written for desktop

PCs is easily ported to the UC-7101 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.
