Overview
DA-685 industrial computers excel in a wide array of power automation applications. The DA-685 series is
based on the Intel x86 processor and supports VGA, 6 Gigabit Ethernet ports, 2 RS-232 serial ports, 6 2 wire
RS-485 serial ports, CompactFlash, and USB. They come in a standard 2U/19’ rackmount chassis. The Intel
Atom processor gives the DA-685 enough punch to perform demanding industrial tasks without consuming a
lot of power or heat, providing users with a highly cost-effective, durable system.
DA-685 computers run Windows Embedded Standard 2009 (pre-installed), providing a familiar environment
for developing sophisticated application software. Moxa provides comprehensive software support to help
programmers develop bug-free code quickly and at a lower cost.
Software Specifications
The software features of the DA-685-XPE embedded computers are listed below:
Application Development Environment
The DA-685-XPE is fully compatible with the XP Professional Development Environment.
The DA-685-XPE’s use of Windows Embedded Standard 2009 with SP3 provides the following common, popular
application development features that make programming convenient and easy.
Every application that runs in Windows XP can be executed in the DA-685-XPE, so there is no migration cost.
Windows Embedded Standard 2009 is based on the same binary files as Windows XP Professional; Windows
Embedded Standard 2009 enables you to rapidly develop reliable and full-featured connected devices.

Starting Your DA-685-XPE Computer
Connect the CRT or LCD monitor to the DA-685-XPE computer, and then power it up by connecting it to the
power adaptor. It takes about 30 to 40 seconds for the system to boot up. Once the system is ready, the
desktop will appear on your monitor.
Resetting Your DA-685-XPE Computer
•To reset the DA-685 computer:
Press the power switch button on the rear panel for more than 1 second to shut down your computer. Press
the power switch again to restart your computer.
•Software Shutdown / Reboot:
Click Start Turn Off Computer to turn off or restart the DA-685-XPE computer.
Changing the Network Settings
The DA-685-XPE computer comes with six network interfaces. All of the default IP addresses are DHCP. Choose
Start Network Connections, and then right-click the network interface icon, select Properties.

Next, click Internet Protocol (TCP/IP) and select Properties to enter the network settings page. The
default values are Obtain an IP address automatically, and Obtain DNS server address automatically.
If you must configure the computer to use a fixed IP address, check Use the following IP address and be
prepared to provide the IP address, subnet mask, and default gateway. You also need to check Use the
following DNS server address, and provide a preferred and/or alternate DNS server. Click Advanced for
more detailed settings. When finished, click OK to complete the network settings.
Operating Your DA-685-XPE Computer with a
Telnet Client
Use a crossover Ethernet cable to connect your development workstation directly to the target computer, the
DA-685-XPE, or use a straight-through Ethernet cable to connect the DA-685-XPE to a LAN hub or switch. Next,
use a telnet client on your development workstation to connect to the Telnet console utility of the DA-685-XPE.
After a connection has been established, type the login name and password as requested to log on to the
computer.
After logging in through the Telnet client, a list of commands will be available for operating the computer. Use
HELP to display all of the commands, or type HELP [command name] to display extended help for the
selected command. Some of these commands, such as DATE and TIME, are very useful for managing the
computer’s system time. Other commands, such as DIR and MKDIR, are good utilities for file management.
For example, to inspect the file structure of the root directory, type DIR.
NOTE
The default user id is “administrator” and the default password is not set; you need to create a new password
for
this account to use this telnet client.
NOTE
There is a connection limitation on using Telnet clients. You are only allowed to create connections with two
Telnet clients at the same time.
