Executive Summary

Moxa wanted to build a platform for substation automation that could handle a large number of LAN and serial ports while withstanding high temperatures in a fanless, 1U standard rack-mount form factor. 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.
