Overview
The DA-682C Series is built around a Intel® Celeron, Intel® Core™ i3, i5
or i7 CPU and comes with dual display ports (2 x HDMI), 5 USB ports, 6
gigabit LAN ports, 2 3-in-1 RS-232/422/485 serial ports, 6 digital Input
ports, and 2 digital output ports. The DA-682C is equipped with two
hot-swappable 2.5” HDD/SSD slots and supports the Intel® RST RAID
0/1 functionality. Additional value and convenience are provided through
a modular design with two independent slots for flexible system
integration and expansion. Users have the option to add a variety of
different communications modules, including an 8-port RS-232/422/485
module and 4-port 10/100/1000 Mbps LAN module.
With IEC 61850-3 and IEEE 1613 compliance, the DA-682C is sure to
deliver stable and reliable system operation for power applications. The
DA-682C also complies with the IEC 60255 standards, which cover the
protection of electrical relays in a smart substation. IEC 60255 is one of
the most widely used standards for testing relays and protection
equipment, and compliance with the standard ensures that the DA-682C
will work reliably and seamlessly with IEDs as part of a robust substation
automation system.

Connecting the Power
The DA-682C provides single or dual power inputs using a terminal block,
which is located on the rear panel. Connect the power cord wires to the
screws, and then tighten the screws. The Power LED will light up to
indicate that power is being supplied to the DA-682C, after which the
BIOS will initialize the flash disk module, causing the Storage LED to
blink. It should take about 30 to 60 seconds for the operating system to
complete the boot up process. A grounding connector is also provided for
power surge protection.

In addition, a power button on the rear panel allows users to power on the
computer when it is in the sleep or hibernate mode.
For detailed power connection and surge protection information, refer to
the DA-682C Hardware User’s Manual.
