1. Introduction

The DA-662A series embedded computers come with 8 to 16 software selectable RS-232/422/485 serial ports,

making them suitable for a variety of industrial applications. Models are available with 4 10/100 Mbps Ethernet

ports. The DA-662A series model also comes with CF and USB ports to make it easy to add additional storage

space. The computers are designed with a standard 19-inch, rugged 1U rackmount case, and are embedded

with a 100-240 VAC power input. This combination of features gives users a robust and reliable ready-to-run

solution for applications such as data acquisition and power substations.

Overview

The DA-662A series are RISC-based, ready-to-run embedded computers designed for industrial data

acquisition applications. Each model has 8 or 16 RS-232/422/485 serial ports, and 2 USB hosts based on the

Moxa Macro 500 MHz communication processor. The DA-662A series has 4 Ethernet ports. The casing is a

standard 1U, 19-inch wide rack-mounted rugged enclosure. The robust, rack-mountable mechanism design

provides the hardened protection needed for industrial environment applications, and makes it easy for users

to install the DA-662A series on a standard 19-inch rack. The DA-662A series are ideal for applications that

require a distributed embedded technology, such as SCADA systems, plant floor automation, and power

electricity monitoring applications.

The DA-662A series are suitable for IT control room applications, the critical assets used in the control and

automation system of industrial plant floors, and in electric power utility substations. The DA-662A series can

accept a wide range of power inputs (from 100 to 240V), which means that they can be connected to AC power

lines. Because of the no hard disk, fan-less, energy efficient design, the DA-662A series minimize heat

generation, can operate around the clock, year in and year out, in heavy duty, harsh industrial environments,

delivering the kind of reliable computing power expected of a multifunctional controller.

Choose from models of the DA-662A series that come pre-installed with the open-standard Linux OS. The

built-in SDK makes program development easy by allowing you to follow the common programming

procedures used on a standard PC. All of the software you develop for your own applications can be stored in

the onboard Flash memory. The DA-662A series embedded computers are ideal for creating control systems

with distributed architecture that are based on embedded technologies. Typical applications include SCADA

systems, plant floor automation, and power electricity monitoring.
