Overview

The AWK-3191 900 MHz radio is Moxa’s answer to the need for long
distance wireless communication for industrial applications. By combining
the characteristics of the 33-centimeter band, and the proven 802.11
standard, Moxa is able to provide a reliable long distance wireless solution.
Unlike traditional point-to-point 900 MHz radios, the AWK-3191 also
provides reliable point-to-multi-point communication for higher flexibility
and lower total cost of ownership. Furthermore, the AWK-3191 is
designed for simple deployment, but in case of external interference,
engineers can adjust their 900 MHz central frequency and bandwidth
(5/10 MHz and 20 MHz) to optimize their wireless communication. With
industrial grade standards and wide-temperature models, the AWK-3191
is the most reliable solution for industrial long distance communication.

Package Checklist

Moxa’s AWK-3191 is shipped with the following items. If any of these
items is missing or damaged, please contact your customer service
representative for assistance.

• AWK-3191

• Cable holder with one screw

• 2 protective caps

• Warranty card

Installation and Configuration

Before installing the AWK-3191, 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. The AWK-3191 has a
default IP address that you must use when connecting to the device for
the first time.

Step 1: Select the power source

The AWK-3191 can be powered by a DC power input or PoE (discontinued
starting with HW Rev 2.0.0). The AWK-3191 will use whichever power
source you choose.

Step 2: Connect the AWK-3191 to a notebook or PC

Since the AWK-3191 supports MDI/MDI-X auto-sensing, you can use
either a straight-through cable or crossover cable to connect the
AWK-3191 to a computer. If the LED indicator on the AWK-3191’s LAN
port lights up, it means a connection has been established.

Step 3: Set up the computer’s IP address

Set an IP address on the same subnet as the AWK-3191. Since the
AWK-3191’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 and subnet mask to 255.255.255.0.

- 3 -

Step 4: Use the web-based manager to configure the AWK-3191

For some applications, it may be more convenient to mount the
AWK-3191 to a wall, as illustrated below:

STEP 1:

Remove the aluminum
DIN

-rail attachment plate

from the AWK

-3191, and

then attach the wall-mount
plates with M3 screws, as
shown in the adjacent
diagram.

STEP 2:

Mounting the AWK

-3191 to a wall requires 4 screws.

Use the AWK

-3191 device, 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 t

he

shafts should be less
than 3.5 mm in diameter, as shown in the figure at the
right.

NOTE

Test the screw head and shank size by inserting the screws into
one of the keyhole shaped apertures of the

wall-mounting p

lates

before attaching the plate to the wall.

STEP 3:

Once the screws are fixed into the wall,
insert the four screw heads through
the large opening of the
keyhole

-shaped apertures of the

wall

-mounting plate, and then slide

Wiring Requirements

WARNING

Safety First!

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

oxa AWK-3191.

Calculate the maximum possible current in each power wire and
common wire. Observe all electrical codes dictating the
maximum current allowed 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 items:

• 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 with similar electrical characteristics can be bundled
together.

• Keep input wiring and output wiring separate.

• It is strongly advised that you label wiring to all devices in the system
when necessary.

ATTENTION

This product is intended to be supplied by a Listed Power Unit
marked “Class 2” or “LPS” and rated O/P: 5.76 W

ATTENTION

Make sure

the external power adapter (inc

ludes power cords and
plug assemblies) provided with the unit is certified and suitable
for use in your country.

Grounding the Moxa AWK-3191

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.

There must be no

pote

ntial difference between two ground potentials; otherwise

there is a risk that the device could be destroyed.

Installations with Cable Extended Antennas for Outdoor

Applications

If the antenna or the AWK device is installed outdoors or in an open-air
setting, proper lightning protection is required to prevent direct lightning
strikes on the AWK device. In order to prevent coupling currents from
nearby lightning strikes, a lightning arrester should be installed as part of
your antenna system. Ground the device, antenna, as well as the arrester
properly to provide maximum outdoor protection for the device.
