x86 rackmount embedded computers with 4 isolated RS-232 and 8
isolated RS-485 ports, 6 LANs, VGA, CompactFlash, USB
The DA-681 computer is based on the Intel x86 processor and
supports VGA, 6 Ethernet ports, 4 RS-232 and 8 RS-485 serial ports
with 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� In addition, the DPP-T models have been certified
to meet the IEC 61850-3 standard, making them ideal for power
substation automation systems�
The DA-681 runs Linux or Windows XP Embedded (pre-installed),
providing a friendly environment for developing sophisticated
application software� The great software support that Moxa provides
makes the programmer’s job easier, and helps programmers develop
bug-free code quickly and at a lower cost�
