DA-681 Linux
Introduction
1-2
Overview
The DA-681 embedded computer is based on the Intel Celeron M processor and 910GMLE chipset, which
supports standard X86 VGA, USB, PS/2 keyboard/mouse, 6 10/100 Mbps LAN ports, and SATA disk interface.
In addition, the DA-681 supports a CompactFlash Socket and pre-installed embedded ready-to-run operating
system. Programmers will find the full-function development kit a great benefit for developing software and
building reliable communication applications.
The housing is a standard 1U, 19-inch wide rack-mounted rugged enclosure. This robust, rack-mountable
design provides the hardened protection needed for industrial environment applications.
Moreover, the DPP-T models are in full compliance with IEC 61850-3 standards to meet the demands of power
substation automation.

ATTENTION
Refer to section “Baud Rate Speed” for calculation of baud rate speed supported.
Software Specifications
The Linux operating system pre-installed on the DA-681 embedded computer is the
Debian Etch
4.0r2
distribution. The Debian project is a worldwide group of volunteers who endeavor to produce an
operating system distribution that composed entirely of free software. The Debian GNU/Linux follows the
standard Linux architecture, making it easy to use programs that meet the POSIX standard. In addition to
Standard POSIX APIs, device drivers for Moxa UART and other special peripherals are also included. An
example software architecture is shown below:
