1. Introduction

The DA-660A 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 with 4 10/100 Mbps Ethernet

ports are also available. The DA-660A 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-660A Series computers are RISC-based, ready-to-run embedded computers designed for industrial

data acquisition applications. The models have either 8 or 16 RS-232/422/485 serial ports, and 2 USB hosts

based on the Moxa Macro 500 MHz communication processor. The DA-660A has 4 Ethernet ports. The

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

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

to install the DA-660A on a standard 19-inch rack. The DA-660A Series computers are ideal for applications

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

electricity monitoring applications.

The DA-660A Series computers 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

computers 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, fanless, and energy-efficient design, the

computers 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.

You can choose DA-660A Series models that come preinstalled 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. The software you develop for your own applications can be stored in the onboard

Flash memory. The DA-660A 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.

LED Indicators

LED indicators are located on the front panel of the DA-660A Series.

LED Name LED Color LED Function

Ready Red Power is On, and system is ready (after booting up)

LAN1, LAN2,

LAN3, LAN4

Orange 10 Mbps Ethernet connection

Green 100 Mbps Ethernet connection

P1-P16 (Rx) Orange Serial port is receiving RX data from the serial device

Off Serial port is not receiving RX data from the serial device

P1-P16 (Tx) Green Serial port is transmitting TX data to the serial device

Off Serial port is transmitting TX data to the serial device

Reset Button

Press the Reset button on the front panel continuously for at least 5 seconds to load the factory default

configuration. After the factory default configuration has been loaded, the system will reboot

automatically. The Ready LED will blink on and off for the first 5 seconds, and then maintain a steady glow

once the system has rebooted.

We recommend that you only use this function if the software is not working properly, and you want to load

factory default settings. To reset an embedded Linux system, always use the software reboot command

/>reboot to protect the integrity of data being transmitted or processed. The Reset button is not designed

to hard reboot the DA-660A Series.

ATTENTION

Pressing the Reset button will only load the configura

tion file. All files in the /etc directory will revert to

their factory defaults, and

all user data in the Flash ROM will be deleted.
