DA-682 Series Hardware User’s Manual Introduction
Overview
The Moxa DA-682 Series of X86-based rackmount embedded computers are designed for
industrial data acquisition applications. The state-of-art 2 expansion module design provides
greater flexibility by allowing combinations of up to 16 RS-232/422/485 serial ports or up to 4+8
Ethernet ports. This friendly design gives users the advantage of being able to swap out modules
quickly and easily. Additional expansion modules will be available soon to provide even greater
flexibility.
The DA-682’s main operating system is based on the Intel Celeron M processor and 915GME
chipset, which supports standard X86 VGA, USB, PS/2 keyboard/mouse, 4 Gigabit LAN ports,
and IDE/SATA disk interface. In addition, the DA-682 has a CompactFlash socket and comes with
Linux, WinCE 6.0, Windows XP Embedded pre-installed. Programmers will find the full-function
development kit a great benefit for developing software and building reliable communication
applications.
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.

Non-standard Baudrates
Moxa’s UART ASIC, which is used for both the DA-SP08-I-DB and DA-SP08-I-TB serial
expansion modules, supports most non-standard baudrates in the range 50 bps to 921.6 Kbps. In
fact, supported baudrates are much denser towards the lower values. For example, no baudrates are
supported between the integers 5320 and 5323, but 49 baudrates are supported between the
integers 387 and 388. Of course this is the way it should be, since serial devices that require using
non-standard baudrates generally use slower baudrates.
Before using a serial device that requires using a non-standard baudrate, you must first check that
the DA-682 supports a baudrate within the tolerance specified by the serial device manufacturer.
Use the following formula to calculate which baudrates are supported by the DA-283:
(A) Baudrate = 921600/(N+M/8) bps, for N = 1, 2, …, 18431, M = 0, 1, 2, …, 7
or
(B) Baudrate = 8 x 921600/K bps, for K = 8, 9, …, 147456
If you are a programmer and you need to write a driver for your serial device, then you may need
to use formula A. If you have a serial device that requires using a non-standard baudrate, then you
can use formula B to determine if the DA-682 supports a baudrate within the tolerance specified
by the serial device manufacturer.
Example: Your serial device requires using a baudrate of 5340 bps and has a tolerance of 2 bps.
Can the DA-682 be used with this device?
Solution: Set formula B to the desired baudrate and then solve for K.
8 x 912600/K = 5338 ==> K = 1367.703259…
This shows that the supported baudrate closest to 5340 comes from setting K=1367 or K=1368.
K=1368 ==> Baudrate1 = 5336.842105...
K=1367 ==> Baudrate2 = 5340.746159…
Since 5338 – Baudrate1 < 2, we can see that the DA-682 supports the serial device.
Note that we can use formula A to generate the so-called “standard” baudrates, which come from
setting M=0, and setting N equal to certain integers.

WARNING
Communication between a serial device and a Moxa UART port may not work correctly if the
serial device uses a baudrate that it not within the correct tolerance of a baudrate calculated from
either formula A or formula B.

Chapter 2 Hardware Installation
The DA-682 Series of embedded computers are compact and rugged, making them suitable for
industrial applications. The LED indicators allow users to monitor performance and identify
trouble spots quickly, and multiple ports are provided for connecting a variety of different devices.
The DA-682 embedded computers come with a reliable and stable hardware platform that lets you
devote the bulk of your time to application development. This chapter describes hardware
installation and connector interfaces of the DA-682 embedded computers.

Placement Options
Desktop
Place your DA-682 on a clean, flat, well-ventilated desktop. For better ventilation, leave some
space between the DA-682 and other equipment. Do not place equipment or objects on top of the
DA-682, as this might damage the computer’s internal components.
Rack mounting
Use four rackmount screws to attach the DA-682 to a standard rack.

Wiring Requirements
The following common safety precautions should be observed before installing any electronic
device:
yUse separate paths to route wiring for power and devices. If power wiring and device wiring
paths must cross, make sure the wires are perpendicular at the intersection point.
yYou can use the type of signal transmitted through a wire to determine which wires should be
kept separate. The rule of thumb is that wiring that shares similar electrical characteristics can
be bundled together.
yKeep input wiring and output wiring separate.
yWhen necessary, it is strongly advised that you label wiring to 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 be 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 common wire. Observe all
electrical codes dictating the maximum current allowable for each wire size.
If the current goes above the maximum ratings, the wiring could overheat, causing serious
damage to your equipment.

DA-682 Series Hardware User’s Manual Hardware Installation
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.
Connecting the Power
To power on the DA-682 embedded computer, connect the power line to the DA-682’s AC power
connector (located on the right side of the rear panel) using the power cord shipped with the
product, and then turn on the power switch. If the power is properly supplied, the Power LED will
light up first, and then the Storage LED will start blinking when the Flash Disk Module is accessed
during boot up. It takes about 30 to 60 seconds for the operating system to boot up.

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 with the software reboot function.
