Overview

The DA-820’s main operating system is based on the Intel® Core™

i3/i7/Celeron CPU and QM77 chipset, and supports x86 platforms. The

DA-820 has 2 VGA connections, 6 USB ports, 4 Gigabit LAN ports, and 2

RS/232/422/485 3-in-1 serial ports, and is equipped with a 4 SATA disk

interface and default support for RAID 0/1/5/10. In addition, the DA-820

is specifically designed for substation applications that require precise

time synchronization and products meeting the IEC 61850-3 standard.

The flexible design makes the DA-820 suitable for local SCADA,

environmental monitoring, video surveillance, protocol conversion, and

PRP/HSR redundancy applications, and the cybersecurity functionality

allows you to maintain secure network communications.

Hardware Installation

Front View

NOTE

The power input supports two types of power supply:

HV: 100 to 240 VAC/VDC

LV: 24 to 110 VDC.

Connecting the Power

Use a screwdriver to loosen the terminal connector’s clamp screws.

Connect the power cord wires to the screws, and then retighten the

screws. The Power LED will light up to indicate that power is being

supplied to the DA-820, 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 process.

Connecting to a Display

The DA-820 comes with 2 VGA interfaces that use D-Sub 15-pin female

connectors.

USB Ports

The DA-820 comes with 6 USB 2.0 ports, with 4 on the rear panel and 2

on the front panel. The USB ports can be used to connect a keyboard,

mouse, or other peripherals, such as flash drives for expanding the

system’s storage capacity.

Serial Ports

The DA-820 comes with 2 software-selectable RS-232/422/485 serial

ports on the rear panel. The ports use DB9 male connectors. Refer to the

Installing Removable Storage

The DA-820 has 4 hot-swappable 2.5” SSD/HDD storage trays located on

the front panel for installing additional storage drives. Remove the screws

on the trays to install the SSD/HDD storage drives. RAID 0, 1, 5, and 10

are supported.

Configuring the Ethernet Interface

Linux Users:

To configure the network settings on your DA-820 for the first time, use

the following commands to edit the interfaces file. First, make sure all

network interfaces are offline before you reconfigure the LAN settings.

MOXA:~# ifdown –a

Next, edit the network interfaces file. The default editor on the DA-820 is

vi; however, you may use a text editor of your choice.

MOXA:~#vi /etc/network/interfaces

You may set the DA-820 for either dynamic IP addressing or static IP

addressing. For dynamic IP addressing, enter the following lines into the

network interfaces file:

# The primary network interface

auto eth0

iface eth0 inet dhcp

To configure an interface for static IP addressing, use the following

configuration. Each interface must be configured with separate entries in

the network/interfaces file; LAN1 corresponds to eth0, LAN 2 corresponds

to eth1, and so on for the remaining interfaces.

- 6 -

# The loopback network interface

auto lo

iface lo inet loopback

# The first LAN interface, LAN 1

auto eth0

iface eth0 inet static

address 192.168.3.127

netmask 255.255.255.0

broadcast 192.168.3.255

# The second LAN interface, LAN 2

auto eth1

iface eth1 inet static

address 192.168.4.127

netmask 255.255.255.0

broadcast 192.168.4.255

Exit the vi editor by typing:

:wq

After the interfaces file has been configured, use the following commands

to reinitialize the network interfaces and activate the new settings

immediately:

Moxa:~#sync; ifup –a

Windows 7 Users

Step 1:

Go to Start Control Panel Network and Internet



Network Connections.

Step 2:

On the Local Area Connection Properties screen, click

Internet Protocol (TCP/IP)

and select Properties.

Step 3:

Click OK after inputting the preferred IP address and

netmask.
