1. Introduction

The Moxa UC-7110/7112 series of embedded computers are 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-7110/7112 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.

UC-7112-LX Plus/UC-7112/UC-7110 Hardware Introduction

Overview

The UC-7110/7112 series of 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-7110/7112 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-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.
