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 RS-232 and 8 RS-485 serial ports with
digital galvanic isolation, CompactFlash, and USB. The DA-681
comes in a standard 19-inch, 1U high form factor, making it an
ideal platform for industrial applications.
With its robust design, the DA-681 is suitable for industrial
automation applications that require standard 19-inch rackmount
solutions, such as power automation, transportation, and oil and
gas. Another plus is that the serial ports come with 2 KV digital
galvanic isolation protection to guarantee communication
reliability in harsh industrial environments.
Moreover, the DPP-T models are in full compliance with IEC
61850-3 standards to meet the demands of power substation
automation.
