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.

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:

and then follow the
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
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
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.

DIN-Rail Mounting
The aluminum DIN-Rail attachment plate should be fixed to the back panel of
AWK-3121 when you take it out of the box. If you need to reattach the
DIN-Rail attachment plate to AWK-3121, make sure the stiff metal spring is
situated towards the top, as shown in the figures below
STEP 1:
Insert the top of the DIN-Rail into the
slot just below the stiff metal spring.

To remove AWK-3121 from the DIN-Rail, simply reverse Steps 1 and 2 above.
Wall Mounting (Optional)
For some applications, you will find it convenient to mount AWK-3121 on the
wall, as illustrated below.
STEP 1:
Remove the aluminum DIN-Rail attachment plate from AWK-3121, and then
attach the wall mount plates, as shown in the diagrams below.
STEP 2:
Mounting AWK-3121 on the wall requires 4 screws. Use the
AWK-3121, with wall mount plates attached, as a guide to
mark the correct locations of the 4 screws. The heads of the
screws should be less than 6.0 mm in diameter, and the
shafts should be less than 3.5 mm in diameter, as shown in
the figure at the right.
Do not screw the screws in all the way—leave a space of
about 2 mm to allow room for sliding the wall mount panel
between the wall and the screws.

NOTE
Test the screw head and shank size by inserting the screw into one
of the keyhole shaped apertures of the Wall Mounting Plates,
before it is screwed into the wall.
STEP 3:
Once the screws are fixed in the wall, insert the four screw heads through the
large parts of the keyhole-shaped apertures, and then slide AWK-3121
downwards, as indicated below. Tighten the four screws for added stability.
Wiring Requirements
ATTENTION
Be sure to disconnect the power cord before installing and/or
ATTENTION
wiring your MOXA AWK-3121.
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.
Safety First!
Safety First!
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.

Grounding MOXA AWK-3121
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from the
ground screw to the grounding surface prior to connecting devices.
ATTENTION
This product is intended to be mounted to a well-grounded
mounting surface such as a metal panel.
Wiring the Redundant Power Inputs
The top two pairs of contacts of the
AWK-3121’s top panel are used for AWK-3121’s two DC inputs. Top and front
views of one of the terminal block connectors are shown here.

ATTENTION
Before connecting AWK-3121 to the DC power inputs,
make sure the DC power source voltage is stable.
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.

Wiring the Digital Inputs
AWK-3121 has two sets of digital input—DI1 and DI2. Each DI comprises
two contacts of the 10-pin terminal block connector on AWK-3121's top
panel. You can refer to the section Wiring the Redundant Power Inputs 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.
Communication Connections
10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on AWK-3121’s front panel are used to
connect to Ethernet-enabled devices.
Below we show pinouts for both MDI (NIC-type) ports and MDI-X
(HUB/Switch-type) ports.

RS-232 Connection
AWK-3121 has one RS-232 (8-pin RJ45) console port, located on the side
panel. Use either an RJ45-to-DB9 or RJ45-to-DB25 cable to connect MOXA
AWK-3121’s console port to your PC’s COM port. You may then use a
console terminal program to access AWK-3121 for console configuration.
