DA-683-LX Introduction
1-2
Overview
DA-683 embedded computers are based on the Intel Atom D510 x86 processor and feature two serial ports,
dual 10/100 or 10/100/1000 Mbps LAN ports, four USB 2.0 hosts, and CF socket. The DA-683 series offers both
VGA and DVI-I outputs, making it exceptionally well suited for industrial applications such as SCADA and
factory automation.
The DA-683's two RS-232 ports make it ideal for connecting a wide range of serial devices, and the dual
10/100/1000 Mbps Ethernet ports offer a reliable solution for network redundancy, which taken together
promise continuous data communication and management operations. For added convenience, the DA-683
comes with 4 DIs and 4 DOs for connecting digital input/output devices. In addition, the SD, SATA HDD, and
USB ports provide DA-683 computers with data buffering and storage expansion, which provide the necessary
reliability for industrial applications.
Pre-installed with Linux, the DA-683 Series provides programmers with a friendly environment for developing
sophisticated, bug-free application software at a lower cost.
The DA-683's DPP-T models support a wide operating temperature range of -40 to 70°C for use in harsh
industrial environments.
Software Specifications
The Linux operating system pre-installed on the DA-683 embedded computer is the Debian Lenny
5.0 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. Program porting is possible with
the GNU Tool Chain provided by Moxa. In addition to Standard POSIX APIs, device drivers for Moxa UART and
other special peripherals are also included. The following is a software architecture example:
ATTENTION
Refer to http://www.debian.org/ and http://www.gnu.org/ for information and documentation of the Debian
GNU/Linux and free software concept.
ATTENTION
The above software architecture is only an example. Different models or different build revisions of the Linux
operating system may include components not shown in the above graphic.
