DA-662A Series

Quick Installation Guide

Version 2.0, January 2019

Overview

DA-662A computers are Arm-based, ready-to-run embedded
computers designed for industrial data acquisition applications.
The DA-662A computers come with 8 to 16 RS-232/422/485 serial
ports, 4 Ethernet ports, and 2 USB 2.0 ports, all based on the Moxa
Macro communication processor. In addition, the
DA-662A-I-8/16-LX’s serial ports support 2k digital isolation and 8
kV contact, 15 kV Air ESD protection and 2 kV line-to-line, as well
as 4 kV line-to-ground surge protection. 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-662A Series on a standard 19-inch rack. The
DA-662A computers are ideal for applications that require a
distributed embedded technology, such as SCADA systems, plant
floor automation, and power electricity monitoring applications.

Installing Your DA-662A Computer

Desktop Mounting

Place the DA-662A on a clean, flat, well-ventilated desktop. For
better ventilation, attach the 4 pads from the desktop kit to the
bottom of the DA-662A, and leave some space between the
DA-662A and other equipment. Do not place equipment or objects
on top of the DA-662A, since doing so could damage it.

Rack Mounting

The DA-662A can be mounted on a standard 19-inch rack. Use the
enclosed pair of L-shaped metal plates and screws to fasten the
DA-662A to the rack cabinet. You can lock either the front panel or
the rear panel of the DA-662A to the front side of the rack. Each
L-shaped plate has 6 holes, leaving two outer or inner holes open
for your convenience.

Connecting Your DA-662A Computer

Power Connector

Connect the 100-240 VAC power line to the DA-662A’s power
connector. The Ready LED on the front panel will glow a steady
green when the OS is ready.

Ethernet Ports

Serial Ports

The DA-662A has 8 or 16 serial ports that use RJ45 connectors.
The ports can be configured independently for RS-232, RS-422, or
RS-485 by software.

Serial Ports (DA-662A-I-8/16-LX only)

Console Ports

The console port is an RJ45 RS-232 port. The pin definitions are
the same as for the serial ports.

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 for the first 5
seconds, and then maintain a steady glow once the system has
rebooted.

LCD Screen

The DA-662A has an LCD screen on the front panel. The LCD
screen displays 16 columns and 2 rows of text. On boot-up, the
LCD screen displays the model name and firmware version, as
shown here:

Real-time Clock

The DA-662A’s real-time clock is powered by a lithium battery. We
strongly recommend that you do not replace the lithium battery
without help from a qualified Moxa support engineer. If you need
to change the battery, contact the Moxa RMA service team.

Powering on Your DA-662A Computer

To power on the DA-662A, connect the power line to the DA-662A’s
AC power connector (located on the right side of the rear panel),
and then turn on the power switch. It takes about 30 seconds for
the system to boot up. Once the system is ready, the Ready LED on
the front panel will light up, and the DA-662A will display the
model name and firmware version on the LCD screen.

Connecting to DA-662A from a PC

There are two ways to connect to the DA-662A from a PC: through
the serial console port or by Telnet over the network. The COM
settings for the serial console port are: Baudrate = 115200 bps,

Parity = None, Data bits = 8, Stop bits = 1, Flow Control =
None.

When using Telnet, you need to know the DA-662A’s IP address
and netmask. The default LAN settings are shown below. For
first-time configuration, you may find it convenient to use a
cross-over Ethernet cable to connect directly from the PC to the
DA-662A.

Once the DA-662A is powered on, the Ready LED will light up, and
a login page will open. Use the following default Login name and
Password to proceed.

Login: root
Password: root

Configuring the Ethernet Interface

If you use the console cable for first-time configuration of the
Network settings, use the following commands to edit the interface
file:

# ifdown –a
//Disable LAN1/LAN2 interface first, before you
reconfigure the LAN settings. LAN 1 = eth0, LAN 2= eth1//
# vi /etc/network/interfaces
//check the LAN interface first//

After the boot settings of the LAN interface have been modified,
use the following commands to activate the LAN settings
immediately:

# sync ; ifup –a

Installing the DA-662A Tool Chain

The PC must have the Linux operating system pre-installed to
install the DA-662A GNU Tool Chain. Redhat 7.3/8.0/9.0 Fedora
Core 1/2/3/4/5 Debian 7 and later compatible versions are
recommended. The Tool Chain will use about 1 GB of your PC’s
hard disk space. Use the following command to install the Tool
Chain from the DA-662A Series CD:

# mount /dev/cdrom /mnt/cdrom
# sh /mnt/cdrom/Toolchain/
arm-linux_x.x.x-Vx_Build_YYMMDDHH.sh

The Tool Chain will be installed on your PC automatically.

Compiling and Running Hello.c

The path to the Tool Chain is:

#export PATH=“/usr/local/arm-linux-4.4.2-v4/bin:$PATH”

The DA-662A software CD also includes several example programs.
Here we use hello.c as an example to show you how to compile
and run your applications. Type the following commands on your
PC:

# cd /tmp/
# mkdir example
# cp –r /mnt/cdrom/example/* /tmp/example

Next, go to the hello subdirectory and type the following
command:

# make

to finish compiling hello.c.

Finally, run the executable file that was created to generate

hello-release and hello-debug.
