ThinkCore DA-660-8/16-LX

Quick Installation Guide

First Edition, May 2006

1. Overview

ThinkCore 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 IXP-422 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 ThinkCore DA-660
products, you can easily build a control system with distributed
architecture for embedded technologies, such as SCADA systems, plant
floor automation, and power electricity monitoring applications.

4. Installing Your ThinkCore DA-660

Desktop Mounting

Place your ThinkCore 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

.

ThinkCore 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 ThinkCore

Power Connector

Connect the 100-240 VAC/VDC power line to ThinkCore 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 --- --­2 RTS TXD+ --­3 GND GND GND
4 TXD TXD- --­5 RXD RXD+ Data+
6 DCD RXD- Data­7 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

ThinkCore 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:

D A - 6 6 0 - 1 6
V E R . 1 . 0

Push Buttons

There are four push buttons on the ThinkCore DA-660’s front panel.
These buttons are used to operate the LCM. Going from left to right, the
buttons are:

P/N: 1802006600000

Real Time Clock

ThinkCore 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 ThinkCore DA-660

To power on the ThinkCore 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. Connecting Your ThinkCore DA-660 to a PC

There are two ways to connect the ThinkCore 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 ThinkCore 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 Your Application

10. Installing the ThinkCore 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 ThinkCore 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 T hinkCor e

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.
