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.

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.

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.
