1. Introduction

The Moxa UC-7101 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 that can

store large amounts of information and provide good computing performance.

UC-7101 Hardware Introduction

Overview

The UC-7101 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) and SDRAM (16 MB) 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 platforms 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.
