Placement Options

Desktop

Place your DA-685 on a clean, flat, well-ventilated desktop. For better ventilation, leave some space between
the DA-685 and other equipment. Do not place equipment or objects on top of the DA-685, as this might
damage the computer’s internal components .

Rack mounting

The DA-685 has rackmount supports for installing the e mbe d ded computer into a standard 19” rack.

ATTENTIONS

For maximum safety, at least two persons should work together to lift, place, and

fasten the

computer to the
rack.
Before you lift or move the computer,

first verify both it and any power to the rack system is turned off.

After installing the rackmount asse mbly (ears , hand le s ), four screws are required to fasten the DA-685 to a
rack.

Follow these steps to mount the DA-685 on a rack:

Step 1: Installing the rack supports (ears)

The rackmount assembly should be included with your DA-685. If you do not find the assembly package
please contact a Moxa representative for rectific a tio n. Each assembly should contain 2 rack ears and 12
FMSM4X6 screws. Please note that the handle and the FMSM5X10 screws are not included in the standard
rackmount assembly; these are optional acce ssor ie s tha t come sep ara te ly . If yo u are inter e s ted , p le ase
contact Moxa for ordering information.

As a final check, make sure that the computer is snugly affixed in pl ace.

Wiring Requirements

The following common safety precautions should be observed before installing any electronic device:

• Strive to use separate, non-intersecting paths to route power and network ing wire s . If powe r wiring and
device wiring paths must cross, make sure the wires are perpendic ular at the intersection point.

• Keep the wires separated according to interface. The rule of thumb is that w iring that s hare s simil ar
electrical characteristic s may be bundled together.

• Do not bundle input wiring with output wiring sep arate .

• When necessary, it is strongly advised that you labe l wir ing to all d evic es in the syste m .

ATTENTION

Do not run signal or communication wiring and power wiring in the same conduit. To avoid interference, wires
with different signal characteristic s

(i.e., different interfaces) sho uld b e route d separately.

DA-683 Series Hardware Installation

2-5

ATTENTION

Safety First!

Be sure to disconnect the power cord before installing and/or

wiring your device.

Caution!

High Electrical Curren t!

Calculate the maximum possible current

for

each power wire and common wire. Observe all electrical codes
dictating the maximum current allowable for e ac h wire si ze .
If the current goes above the

maximum ratings, the wiring could overheat, causing serious damage to your

equipment.

Caution! High

Temperatures!

Be careful when handling the unit. When the unit is plugged in, the internal components generate

a lot of

heat

which may leave

the outer casing too hot to touch.

Connecting the Power Supply

The DA-685 offers both single power and dual power inputs. Use a screwdriver to remove the screws. Connect
the power cord to the screws and then attach the screws to the unit. For single models (SP), use Power 1 only;
for dual power models (DPP-T), use both Power 1 and Power 2 for power input insta llation. Refer to the
following figure for detailed information.

Upgrading the BIOS

This section describes how to upgrade the BIOS. However, please note that it is easy to permanently damage
the computer when upgrading the BIOS. We strongly reco mmend that yo u contac t Mox a’s technic al supp or t
staff for assistance in order to obtain all necessary tools and the most current advice before attempting to
upgrade the BIOS on any Moxa device.

Step 1: Create a Bootable USB Disk.
Before upgrading the BIOS every user should first create a bootable USB RAM drive as a system rescue device.

A useful software suite for building USB RAM drives may be found by searching for HP USB Disk Storage
Format Tool, which may then be downloaded and used to create a bootable RAM drive.

To create a rescue system, you will also need to download the FreeDos system files kernel.sys and
command.com from http://www.freedos.org/kernel/.

Copy the DOS files kernel.sys and command.com to a specified directory (C:\FreeDOS in this example).
Start the HP USB Disk Storage Format Tool and in the drop-down menu labeled Device select the USB de vice

that you want to use as a bootable disk.
Configure it to use a FAT file system from the File System drop-down.
Enter a drive name in the Volume Label field.
Check the option Create a DOS Startup Disk under Format Options.
Specify the directory where the system files are located (for example, C:\FreeDOS).
Click Start to format and create the bootable USB drive.

DA-683 Series BIOS Setup

3-14

ATTENTION

We suggest you use a USB drive with under 2 GB in disk space, as larger USB drives may not support the FAT
file format and

will consequently fail to boot.

Step 2: Prepare the Upgrade File.

You must use the BIOS upgrade installation file to upgrade the BIOS. You can send your reques t to Moxa ' s
technical support team at [e-mail] to get an updated version of the BIOS.

1. Get the BIOS upgrade installa tio n file. The file name should have following format: 685xxSxx.exe (xx
refers to version numbers)

2. Copy the f il e to the Bootable USB Disk.

Step 3: Run the upgrade pr ogr a m o n the DA-685 computer

1. Reboot the computer and go to the Boot Manager by pressing F12 while booting up, before the operating
system has begun to load.

2. Select USB Disk as the first boot source. Press Enter to co ntinue.

DA-683 Series BIOS Setup

3-15

3. Once the computer boots, a DOS screen will appear. Go to the directory where the upgrade file is located.
For example, if the upgrad e f ile is store d in the DA685 folder, type:

#:/cd DA685

C:\ cd DA685

4. Run the upgrade program by typing 68510S05.exe.

Please note that the upgrade filename may vary depending on the firmware version.

C:\ DA685>68510S05.exe

5. The upgrade program will run. Wait until the proc edure is finished before initiating any changes to the
system. Be patient; the upgrade will take quite a few minutes.

DO NOT ALLOW THE COMPUTER TO POWER DOWN! DO NOT REMOVE THE USB DRIVE!

6. Once the upgrade is finished, the computer will automatically reboot. To check and see if the up grade was
successful, navigate to the BIOS Main Page and note the BIOS Version numbe r.

ATTENTION

Do NOT switch off the power su pply duri ng

the BIOS upgrade. Doing so will likely cause

permanent

damage to your

system!
