Non-standard Baudrates
Moxa’s UART ASIC, 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-683
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-683:
(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
1-6

DA-683 Series Introduction
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-683 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-683 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-683 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.
Standard Baudrates
Baudrate N M Baudrate N M
115200 8 0 1800 512 0
57600 16 0 1200 768 0
38400 24 0 600 1536 0
19200 48 0 300 3072 0
9600 96 0 150 6144 0
7200 128 0 75 12288 0
4800 192 0 50 18432 0
2400 384 0
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.

DA-683 Series Hardware Installation
Placement Options
Desktop
Place your DA-683 on a clean, flat, well-ventilated desktop. For better ventilation, leave some space between
the DA-683 and other equipment. Do not place equipment or objects on top of the DA-683, as this might
damage the computer’s internal components.
Rack mounting
The DA-683 has rackmount supports for installing the embedded computer on a standard rack.
ATTENTIONS
For maximum safety, at least two persons should work together to lift, place, and attach the embedded
computer to the rack.
Before you lift or move the embedded computer, make sure that the embedded computer is turned off and the
power to the rack system is turned off.
Four rackmount screws are required to attach the DA-683 to a standard rack.
Rackmount screws Rackmount screws
Follow these steps to install the DA-683 on a rack.
Step 1: Installing the rackmount supports.
Take the rackmount supports out of the packages. There are two packages, each of which contains 1
rackmount support, 1 rackmount hanger, 2 FMSM5X10 screws, and 6 FMSM4X6 screws.

Step 2: Installing rackmount hanger to the support.
Use 2 FMSM5X10 screws to attach the rackmount hanger to the ear. Repeat this procedure for the
additional support and hanger.
Step 3: Installing the rackmount ears to the DA-683.
Use 6 screws to attach one rackmount ear to one side of the DA-683. Repeat this procedure for the ear on
the other side of the DA-683.
Step 4: Installing the DA-683 to a rack.
Gently slide the DA-683 onto the rack, and then use screws provided by the rack supplier to fix the
rackmount support to the rail.
NOTE That four screws are required to attach the DA-683 to the rack. Use two screws on the left side and two screws
on the right side.
2-3

DA-683 Series Hardware Installation
As a final check, make sure that the four screws are firmly attached to the rack.
Wiring Requirements
The following common safety precautions should be observed before installing any electronic device:
•Use 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.
•You 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.
•Keep input wiring and output wiring separate.
•When 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.
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
The DA-683 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 installation. Refer to the

DA-683 Series Hardware Installation
Connecting a PS/2 Keyboard and Mouse
Your DA-683 embedded computer comes with a PS/2 mini-DIN connector to connect to a PS/2 keyboard and
PS/2 mouse by using a Y-type cable. This 6-pin mini-DIN connector has the pin assignments shown below.

Use the Y-type cable to convert the mini-DIN connector into two 6-pin mini-DIN connectors to connect both a
PS/2 keyboard and PS/2 mouse at the same time. (The Y-type cable is not included in the accessory package.
It should be purchased separately. You may also use the USB ports to connect your USB-based keyboard and
mouse.)
ATTENTION
Please note that without the Y-type cable, the PS/2 connector on the DA-683 can only work with a PS/2
keyboard. A PS/2 mouse will not function when directly connected to the PS/2 connector on the DA-683
embedded computer.
