Overview
Are your applications hard to wire, or are your wiring costs out of control? Are
you already using mobile equipment that connects over a TCP/IP network? If
so, then what you need is the AWK-3121Access Point/Bridge/AP Client. The
AWK-3121 is rated to operate at temperatures ranging from 0 to 60°C for
standard models and -40 to 75°C for extended temperature models, and is
rugged enough for any harsh industrial environment. Installation is easy, with
either DIN-Rail mounting or distribution boxes. The DIN-rail mounting ability,
wide operating temperature range, and IP30 housing with LED indicators make
the AWK-3121 a convenient yet reliable solution for any industrial wireless
application.
Package
Checklist
MOXA AWK-3121 is shipped with the following items. If any of these items is
missing or damaged, please contact your customer service representative for
assistance.
l 1 Í AWK-3121
l 2 Í Swivel-type antenna (2dBi, RP-SMA, 2.4&5GHz)

Installation
and Configuration
Before installing AWK-3121, check to make sure that all items in the Package
Checklist are in the box. In addition, you will need access to a notebook
computer or PC equipped with an Ethernet port. AWK-3121 has a default IP
address that you must use when connecting to AWK-3121 for the first time.
Step
1:
Select
the
Power
Source
AWK-3121 can be powered by a DC power input or PoE (Power over
Ethernet). AWK-3121 will use the power source that you choose.
Step
2:
Connect
AWK-3121
to
a
notebook
or
PC
Since AWK-3121 supports MDI/MDI-X auto-sensing, you can use either a
straight-through cable or cross-over cable to connect AWK-3121 to the
notebook, if the LED on AWK-3121’s LAN port lights up, it means the
connection is established.
Step
3:
Set
up
the
computer’s
IP
address
Set an IP address on the same subnet as the AWK-3121. Since AWK-3121’s
default IP address is 192.168.127.253, and the subnet mask is 255.255.255.0,
you should set the IP address of the computer to 192.168.127.xxx.
Step
4:
Use
the
web-based
manager
to
configure
AWK-3121
Open your computer’s web browser and then type http://192.168.127.253 in
the address box to access the homepage of the web-based Network Manager.
Before the homepage opens, you will need to enter the user name and
password as shown in the following figure. For first-time configuration, enter
the default user name and password and then click on OK:
User
name:
admin
Password:
root
-

-
NOTE
For
security
reasons,
we
strongly
recommend
changing
the
password.
To
do
so,
open
the
Network
Manager
homepage,
click
on
Maintenance
>
Password
,
and
then
follow
the
onscreen instructions.
Step
5:
Select
the
operation
mode
for
AWK-3121
By default, AWK-3121’s operation mode is set to AP. You can change the
setting if you would like a Client mode or other operation mode.
NOTE
To make the change effect, you must click
Activate
button
after you change the settings.
Step
6:
Test
communications
We describe two test methods. Use the first method if you are using only one
AWK-3121, and use the second method if you are using two or more
AWK-3121s
Testing Method for one AWK-3121
If you are only using one AWK-3121, you will need a second notebook
computer equipped with a WLAN card. Configure the WLAN card for
connecting to AWK-3121 (the default SSID is MOXA), and change the IP
address of notebook B so that it is on the same subnet as notebook A.
After connecting the WLAN card, connect to AWK-3121 and open a DOS
window on notebook B. At the prompt, type
ping
IP
address
of
notebook
A
and then press Enter key. A “Reply from IP address …” response means the
communication was successful. A “Request timed out.” response means the
communication failed. In this case, recheck the configuration to make sure
the connections are correct.
Testing Method for two or more AWK-3121s
If you have two or more AWK-3121s, you will need a second notebook
computer equipped with an Ethernet port. Use the default settings for the
first AWK-3121, and change the second or third AWK-3121 to AP Client
mode and then configure the notebook and AWK-3121s properly.
After setting up the testing environment, open a DOS window on notebook
B. At the prompt, type
ping
IP
address
of
notebook
A
and then press Enter key. A “Reply from IP address …” response means the
communication was successful. A “Request timed out.” response means the
communications failed. In this case, recheck the configuration to make sure
the connections are correct.

Wiring
Requirements
ATTENTION
Safety
First!
Be
sure
to
disconnect
the
power
cord
before
installing
and/or
wiring
your
MOXA
AWK-3121.
ATTENTION
Safety
First!
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.
You should also pay attention to the following points:
§ 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.
NOTE: Do not run signal or communications wiring and power wiring in the
same wire conduit. To avoid interference, wires with different signal
characteristics should be routed separately.
§ 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 separated.
§ It is strongly advised that you label wiring to all devices in the system when
necessary.

Wiring
the
Relay
Contact
AWK-3121 has one relay output, which consists of the two contacts of the
terminal block on AWK-3121’s top panel. Refer to the previous section for
detailed instructions on how to connect the wires to the terminal block
connector, and how to attach the terminal block connector to the terminal
block receptor. This relay contacts are used to detect user-configured events.
The two wires attached to the Fault contacts form an open circuit when a
user-configured event is triggered. If a user-configured event does not
occur, the Fault circuit will be closed.

FEDERAL COMMUNICATIONS COMMISSION INTERFERENCE STATEMENT
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
– Reorient or relocate the receiving antenna.
– Increase the separation between the equipment and receiver.
– Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
– Consult the dealer or an experienced radio/TV technician for help.
CAUTION:
Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions:
(1) This device may not cause harmful interference and
(2) This device must accept any interference received, including interference that may
cause undesired operation.
FCC RF Radiation Exposure Statement
This equipment must be installed and operated in accordance with provided instructions
and the antenna(s) used for this transmitter must be installed to provide a separation
distance of at least 20 cm from all persons and must not be co-located or operating in
conjunction with any other antenna or transmitter. End-users and installers must be
provide with antenna installation instructions and transmitter operating conditions for
satisfying RF exposure compliance.
Outdoor operations in the 5.15-5.25GHz band is prohibited.
