Overview

The DA-680 computer is built around an Intel® Core™ i3 processor and

comes with 8 Gigabit Ethernet ports, 1 VGA port, 8/16 isolated RS-485

serial ports, and 5 USB ports. Additionally, one 2.5” HDD/SSD slot and

one mSATA slot are included to enable storage expansion for industrial

applications that require large storage space for edge data acquisition.

With IEC 61850-3, IEEE 1613, and IEC 60255 compliance, the DA-680

is sure to deliver stable and reliable system operation for power

applications.

Installing the DA-680

The DA-680 comes with a rack-mounting kit. Following these guidelines

when installing the computer.

1. Elevated Operating Ambient: If installed in a closed or multi-

unit rack assembly, the operating ambient temperature of the rack

environment may be greater than room ambient. Therefore,

consideration should be given to installing the equipment in an

environment compatible with the maximum ambient temperature

(Tma) specified by the manufacturer.

2. Reduced Air Flow: Installation of the equipment in a rack should

be such that the amount of air flow required for safe operation of

the equipment is not compromised.

3. Mechanical Loading: Mounting of the equipment in the rack

should be such that a hazardous condition is not achieved due to

uneven mechanical loading.

4. Circuit Overloading: Consideration should be given to the

connection of the equipment to the supply circuit and the effect

that overloading of the circuits might have on overcurrent

protection and supply wiring. Appropriate consideration of

equipment nameplate ratings should be used when addressing this

concern.

5. Reliable Earthing: Reliable earthing of rack-mounted equipment

should be maintained. Particular attention should be given to the

power supply to connections other than direct connections to the

branch circuit (e.g., use of power strips).

Connecting the Power

The DA-680 provides single power (SP model) and dual power (DPP

model) inputs. Use a screwdriver to remove the terminal clamp screws.

Connect the power cord to the screws, and then fasten the screws to

the unit. Refer to the following figure for detailed information.

NOTE

1. Disconnect all power supply cords before performing

maintenance on the product.

2. Connect the connector to the chassis ground source

. Use a

Yellow/Green wire with minimum 18 AWG.

ATTENTION

This product is intended to be

mounted on to a well-grounded

mounting surface such as a metal panel.

ATTENTION

ere is a risk of explosion if the internal clock’s battery is

replaced with an incompatible battery.

- 5 -

When finished, press the Power Switch button on the rear panel to start

the system. It will take about 30 to 60 seconds to boot up, depending

on your operating system.

ATTENTION

1. Disconnect all power sources before you connect the

power wires.

2. This product may create a shock hazard. Be careful while

connecting the power wires.

3. Equipment is intended for installation in restricted access

area.

- 6 -

ATTENTION

IEC-60417-6172 (2012-09)

1. This product may create a shock hazard. Disconnect all

power sources before connecting wires or servicing the

product.

2. This equipment is intended for installation in a restricted

access area.

Reset Button

Pressing the Reset button initiates a 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.

NOTE

All unsaved data will be lost when you push the Reset button.

Connecting to a Display

The DA-680 comes with a D-Sub 15-pin female connector to connect to

the VGA monitor. Be sure to remove the power before you connect or

disconnect the monitor cable.

USB Ports

The DA-680 comes with 2 USB 2.0 ports on the front panel and 3 USB

3.0 ports on the rear panel. The USB ports can be used to connect

peripherals, such as flash drives, for expanding the system’s storage

capacity.

Serial Ports

The DA-680 comes with 8/16 RS-485 serial ports on the rear panel with

Terminal Block connector. Refer to the following table for the pin

assignments:

Relay Output

The DA-680 provides a relay output located on the rear panel of the

computer and a setting on the power terminal block. Refer to the figure

below for a detailed pin definition of the relay output connectors. The

default setting for the relay is NO. To change the relay setting to NC,

you will need to open the cover and change the setting of the jumper

on the PCB board.

ATTENTION

The r

elay output is only suitable for connecting to a circuit in

compliance with PS2

or LPS according to IEC 62368-

1 rated 30

VDC, maximum 2 A.

Installing a Storage Drive

The DA-680 is provided with a storage slot for storage expansion using

a SATA drive. You will need to purchase an accessory kit that includes a

tray, screws, and cables to install the SATA drive.

To install a SATA disk in the storage slot, do the following:

1. Open the top cover and confirm the location of the slot.

- 10 -

2. Remove the screws and install 3 copper pillars as indicated.

3. Place the SATA drive on a tray, ensure that the SATA disk aligns

with the screws on the storage tray, and fasten the screws.

4. Connect the cables to the SATA drive as indicated below.

5. Place the tray with the SATA drive on the pillars in the slot and

fasten the screws.
