DA-660-8/16-LX
Quick Installation Guide
Third Edition, April 2009
1. Overview
DA-660 products are RISC-based ready-to-run embedded computers
designed for industrial data acquisition applications. They feature 8 or 16
RS-232/422/485 serial ports and dual Ethernet ports based on the Intel
XScale IXP422 communication processor. The casing is a standard 1U,
19-inch wide rack-mounted rugged enclosure. This robust,
rack-mountable mechanism design provides the hardened protection
needed for industrial environment applications, and lets users easily
install DA-660 on a standard 19-inch rack. Using DA-660 products, you
can easily build a control system with distributed architecture for
embedded technologies, such as SCADAsystems, plant floor automation,
and power electricity monitoring applications.

4. Installing Your DA-660
Desktop Mounting
Place your DA-660 on a clean, flat, well-ventilated desktop. For better
ventilation, attach the 4 pads from the desktop kit to the bottom of the
unit, and leave some space between the DA-660 and other equipment. Do
not place equipment or objects on top of the unit, as this can cause
damage to the product.
Rack Mounting.
DA-660 can be mounted on a standard 19-inch rack. Use the enclosed
pair of L-shaped metal plates and screws to fasten your DA-660 to the
rack cabinet. There are two options to do this. You can lock either the
front or the rear panel of the DA-660 to the front side of the rack. Each
L-shaped plate has 6 holes, leaving two outer or inner holes open for your
convenience.
5. Connecting Your
Power Connector
Connect the 100-240 VAC/VDC power line to DA-660’s power
connector. If the power is properly supplied, the Ready LED on the front
panel will glow a solid green when the OS is ready.
Ethernet Port
The two 10/100 Mbps Ethernet ports (LAN 1 and LAN 2) use RJ45
connectors.

Serial Port
There are eight serial ports (P1 to P8) on DA-660-8 and 16 ports on
DA-660-16. All serial ports use RJ45 connectors. Each port can be
configured by software as type RS-232, RS-422, or RS-485. The pin
assignments are shown in the following table:
Pin RS-232 RS-422 RS-485
1 DSR --- ---

3 GND GND GND
4 TXD TXD- ---
5 RXD RXD+ Data+
6 DCD RXD- Data-
7 CTS --- ---
8 DTR --- ---

Console Port
The console port is an RJ45 RS-232 port. It can be connected to a V90 or
GPRS modem via PPP. 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.
LCM Screen
DA-660 has an LCM screen on the front panel. The LCM can display 16
columns and 2 rows of text. After the DA-660 successfully boots up, the
LCM will display the model name and firmware version as shown:
DA-660-16
VER.1.0
Push Buttons
There are four push buttons on the DA-660’s front panel. These buttons
are used to operate the LCM. Going from left to right, the buttons are:
P/N: 1802006600012

Real Time Clock
DA-660’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.
ATTENTION
There is a risk of explosion if the battery is replaced by an incorrect type.
6. Powering on Your DA-660
To power on the DA-660, connect the power line to the DA-660’s
AC/DC power connector (located on the right side of the rear panel) with
the power cord that is shipped with the product. 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-660 will display its model name and firmware version on the LCM
display.
7. ConnectingYour DA-660 to a PC
There are two ways to connect the DA-660 to a PC: through the serial
console port or via 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.
ATTENTION
Remember to choose the “VT100” terminal type. Use the
CBL-RJ45F9-150 cable included with the product to connect a PC to
DA-660’s serial console port.
To use Telnet you will need to know DA-660’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-660.
Default IP Address Netmask
LAN 1 192.168.3.127 255.255.255.0
LAN 2 192.168.4.127 255.255.255.0
Once the DA-660 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
8. 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 interfaces file:
#ifdown –a
//Disable LAN1/LAN2 interface first, before you
reconfigure the LAN settings. LAN 1 = ixp0, LAN 2=
ixp1//
#vi /etc/network/interfaces
//check the LAN interface first//
After the boot settings of the LAN interface has been modified, use the
following commands to activate the LAN settings immediately:
#sync ; ifup –a
9. Developing YourApplication
10. Installing the DA-660 Tool Chain
The PC must have the Linux Operating System pre-installed to install the
DA-660 GNU Tool Chain. Redhat 7.3/8.0, with Linux Kernel 2.4.18 and
compatible versions are recommended. The Tool Chain will use about
400 MB of your PC’s hard disk space. Use the following command to
install the Tool Chain from the DA-660 CD:
#mount /dev/cdrom /mnt/cdrom
#rpm –ivh /mnt/cdrom/mxscaleb-3.3.2-x.i386.rpm
The Tool Chain will be installed on your PC automatically.
11. Compiling and Running Hello.c
The path to the Tool Chain is:
PATH=/usr/local/mxscaleb/bin:$PATH
The DA-660 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.
NOTE: Moxa also provides the Windows Tool Chain for DA-660. The
Windows Tool Chain simulates a Linux environment on a Windows
operating system, allowing you to develop programs for DA-660 on a
Windows platform. The DA-660 User’s Manual contains complete details
on how to install the Windows Tool Chain.
