Embedded Computer
Quick Installation Guide
Third Edition, June 2012
1. Overview
The DA-681 computer uses the Intel x86 processor and supports
VGA, 6 Ethernet ports, 4 R S-232 and 8 RS-485 serial ports w ith
digital galvanic isolation, CompactFlash, and USB. The DA-681
comes in a standard 19-inch, 1U high form factor, making it an
ideal platform f or industrial a pplications.
With its robust design, the DA-681 is suitable for indu strial
automation applications that require standard 19-inch rackmount
solutions, such as power automation, transportation, and oil and
gas. Another plus is that the se rial ports come with 2 KV digita l
galvanic isolation protection to guarantee communication
reliability in harsh industrial environments.
Moreover, the DPP-T models are in fu ll compliance w ith IEC
61850-3 standards to meet the demands of power substation
automation.

4. Configuring the Ethernet Interface
Linux users should follow these steps:
If you use the console cable to configure Network settings for the
first time, use the following co mmands to edit the interface s file:
#ifdown –a
//Disable LAN1~LAN6 interface first, before you
reconfigure the LAN settings. LAN1 = eth0, LAN2 = eth1
and so on//
#vi /etc/network/interfaces
//check the LAN interface first//
After the boot setting of the LAN interface has been modified, use
the following commands to activate the LAN settings immediately:
#sync; ifup –a
WinXPE users should follow these steps:
Step 1: Go to Start Settin gs Network Connections
.
Step 2:
In the screen of Local Area Connection Properties,
click
Internet Protocol (TCP/IP) and then select
Properties
.
Step 3: Click OK
after inputting the proper IP address and
netmask.
NOTE
Refer to the User’s Manual for additional configuration
information.
