The new DA-681 Series rack-mount embedded computer is designed to service the communications traffic generated by as many as six Ethernet ports and a mix of twelve RS-232/ RS-485 ports. This high level of I/O capacity and flexibility is needed as power substations transition from analog to digital, which requires integrated communications and control systems for managing various equipment inside a power substation. Moxa is a leader in industrial serial communication, using its own serial technology to serve the most diverse and demanding requirements. Using Intel’s leading CPU technology, Moxa was able to build an “industrial off-the-shelf” computer system that stands up to the extreme environmental conditions of the power substation.
The Moxa design team chose Intel’s mobile product line to power their DA-681 rack-mount embedded computer because it offers high levels of computing performance while enabling a fanless solution. Further decreasing power consumption, the DA-681 automatically throttles (reduces) the operating frequency of the processor, if the system runs hot, through the use of Moxa-designed BIOS features. “With Intel® processors, our energy customers have the computing headroom to run pre-installed operating systems, like Linux, Windows WinCE 6.0, or XP Embedded, in addition to executing many protocol stacks, protocol conversion routines and
data pre-processing algorithms needed to monitor and control power systems,” says Hermann Berg of Moxa.
