DA-682C Series Introduction
1-2
Overview
The DA-682C computer is built around an Intel® Celeron® or Intel® Core™ i3, i5, or i7 CPU and comes with
dual display ports (2 x HDMI), 5 USB ports, 6 gigabit LAN ports, two 3-in-1 RS-232/422/485 serial ports, 6
digital input ports, and 2 digital output ports. The DA-682C is equipped with 2 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 a 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. It 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.
EN 50121-4 compliance confirms that the DA-682C can deliver stable and reliable system operations in rail
wayside applications, such as station SCADA systems, wayside disaster prevention, traction power, and
signaling and safety systems to provide an integrated view of your smart rail setup. The housing is a standard
2U, 19-inch wide, rack mounted rugged enclosure. This robust, rack mountable design provides the hardened
protection needed for industrial environment applications.

Wiring Requirements
The following common safety precautions should be observed before installing any electronic device:
•Power wires and communication/signal wires should be routed through separate paths. If power and
communication/signal wires must cross paths, make sure the wires are perpendicular at the intersection
point.
•Use the type of signal transmitted through a wire to determine which wires should be bundled together and
which kept separate. The rule of thumb is that wiring that carries similar electrical signals can be bundled
together.
•When necessary, we strongly advise labeling the wiring for all devices in the system.
ATTENTION
Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid interference,
wires with different signal characteristics should b
e routed separately.
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring
your device.
Electrical Current Caution!
Calculate the maximum possible current in each power wire and comm
on wire. Observe all electrical codes
dictating the maximum current allowable for each wire size.
If the current goes above the maximum rating, the wiring could overheat, causing serious damage to your
equipment.
Temperature Caution!
Be
careful when handling the unit. When the unit is
plugged in, the internal components generate heat, and
consequently the
outer casing may feel hot to the touch.
Restricted Access Location
This equipment is intended to be used in Restrict Access Location, like computer room. The access can only be
gained by SERVICE PERSONS or by USERS who have been instructed about the metal chassis of the equipment
is so hot that service persons have to pay special attention or take special protection before
touching it.
Further, the access is through the use of key or security identity system. Only authorized by well trained
professional person can access the restrict access location.
External metal parts are hot!! Before touching it, special attention or protection is necessary.

Connecting the Power
The DA-682C provides 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.
Wiring the Power Inputs
The DA-682C computers come with single power input and dual power inputs models. Refer to the following
diagrams and table for a detailed description of the power input wiring. The terminal numbers referred to in the
table are shown in the diagrams below.
Terminal Number Description Note
1
Power Line PWR Line is connected to the Line (L) terminal for the AC
power source.
Power Positive PWR Positive is connect to the Positive (+)
terminal for the
DC power source
2 NA No function
3
Power Neutral PWR Neutral is connected to the Neutral (N) terminal for the
AC power source.
Power Negative PWR Negative is connect to the Negative (–) terminal for the
DC Power
4 NA No function
5 Bond Earth Bond Earth is connected to the Chassis Ground via a
jumper
on the terminal block.

Grounding the Chassis
There is a grounding connector located on the rear panel of the computer.
Connect the connector to the chassis ground source.
ATTENTION
If protective earthing is use
d as a safeguard, the instructions shall require connection of the equipment
protective earthing conductor to the installation protective earthing conductor (for example, by means of a
power cord connected to a socket
-outlet with earthing connection).
Power Wiring Methods
The DA-682C comes with single or dual power inputs; both AC and DC power sources are supported. Refer to
the following diagrams for detailed wiring methods.
ATTENTION
Equipment must be installed acc
ording to the applicable country’s wiring codes.

In addition, there is a power button on the rear panel, which allows users to power on the computer in case the
computer is in the sleep or hibernate mode.
Reset Button
Pressing the Reset button initiates a hardware warm reboot. The button plays the same role as a desktop PC’s
reset button. After pressing the reset button, the system will reboot automatically. During normal use, you
should NOT use the Reset Button. You should only use this button if the software is not working properly. To
protect the integrity of data being transmitted or processed, you should always reset the system from the
operating system using the software reboot function.
LED
There are 60 LED indicators on the front panel.
