Overview

Moxa’s new AWK-3131A 3-in-1 industrial wireless Access Point meets the
growing need for faster data transmission speeds and wider coverage by
supporting IEEE 802.11n technology with a net data rate of up to 300
Mbps. The AWK-3131A combines two adjacent 20 MHz channels into a
single 40 MHz channel to deliver a potent combination of greater
reliability and more bandwidth. The two redundant DC power inputs
increase the reliability of the power supply, and the AWK-3131A can be
powered via PoE to make deployment easier. The AWK-3131A can
operate on either the 2.4 or 5 GHz bands and is backwards-compatible
with existing 802.11a/b/g deployments.

Mounting Dimensions (unit = mm)

DIN-Rail Mounting

The aluminum DIN-rail attachment plate should be fixed to the back panel
of the AWK-3131A when you take it out of the box. If you need to reattach
the DIN-rail attachment plate to the AWK-3131A, 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.

STEP 2:
The DIN

-rail attachment unit will

snap into place as shown below.

To remove the AWK-3131A from the DIN rail, reverse Steps 1 and 2.

- 5 -

Wall Mounting (optional)

For some applications, it may be more convenient to mount the
AWK-3131A to a wall, as illustrated below.

STEP 1:

Remove the aluminum
DIN

-rail attachment plate

from the AWK

-3131A, and

then attach the wall mount
plates with M3 screws, as
shown in

the adjacent

diagrams.

STEP 2:

Mounting the AWK-3131A to a wall requires 3 screws.
Use the AWK

-3131A device, with wall mount plates

attached, as a guide to mark the correct locations of
the 3 screws. The heads of the screws should be less
than 6.0 mm i

n diameter, and the

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

Do not drive 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 screws into
one of the keyhole shaped apertures of the wall-mounting plates
before they are fixed 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, and then

slide the AWK

-3131A downwards, as

indicated to the right. Tighten the
three screws for added stability.

WARNING

•

This equipment is intended to be used in a location with

restricted access, such as a dedicated computer room

where

only authorized service personnel or users can gain acc

ess.

Such personnel must be instructed about the fact that the
metal chassis of the equipment is extremely hot and may
cause burns.

•

Service personnel or users have to pay special attenti

on and

take special precautions before handling the equipment.

•

Access to the room where the equipment is installed must

be

controlled

by the authority responsible for the location either

through the use of a lock and key or a security identity
system. Only authorized, well-trained professionals should
be allowed to access the restricted access location.

•

Wiring Requirements

WARNING

Safety First!

Be sure to disconnect t

he power cord before installing and/or

wiring your Moxa AWK-3131A.

WARNING

Safety First!

Calculate the maximum possible current in each power wire and
common wire. Observe all electrical codes that dictate 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.

oduct is intended to be mounted to a well-grounded

mounting surface, such as a metal panel.

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. Install lightning arresters, both for the device and
the antenna system, and ground the device as well as the arrester
properly to provide maximum outdoor protection for your device.

Wiring the Redundant Power Inputs

The top two pairs of contacts of the 10-contact terminal block connector
on the AWK-3131A’s top panel are used for the AWK-3131A’s two DC
inputs. Top and front views of the terminal block connector are shown
below.

STEP 1: Insert the negative/positive DC wires
into the

V-/V+ terminals.

STEP 2:

To keep the DC wires from pulling

loose,
use a small flat-blade screwdriver to tighten the
wire

-clamp screws on the front of the terminal

block connector.

STEP 3:

Insert the plastic terminal block

connector prongs into the terminal block
receptor, which is

located on the AWK-3131A’s

t

op panel.

NOTE: Input Terminal Block (CN1) is suitable for
