Overview
The 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 the 5 GHz band and is backwards-compatible
with existing 802.11a/b/g deployments.
Hardware Setup
This section covers the hardware setup for the AWK-3131A.

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.

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
-mounting 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-mounting 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 in 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-mounting 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
Restricted Access
Location, such as a dedicated computer room where only
authorized service personnel or users can gain access.
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 attention and
take special precautions before handling this equipment.
•
Only authorized, well-
trained professionals should be allowed
to access the restricted access location. Access should be
controlled by the authority responsible for the location with
lock and key or a security identity system.
•
External metal parts are hot!! Pay special attention or
use
special protection before handling the equipment.
Wiring Requirements
WARNING
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your AWK
-3131A.
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.
Read and Follow These Guidelines:
•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 crossing 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.
•For future reference, you should label the wiring used for all of your
devices.
ATTENTION
This product is
intended to be supplied by a Listed Power Unit
marked “Class 2” or “LPS” and rated O/P: 7.2 W

- 8 -
ATTENTION
Make sure
the external power adapte
r (includes power cords and
plug assemblies) provided with the unit is certified and suitable
for use in your country.
ATTENTION
DO NOT
use a
PoE Injector. Instead, use an IEEE 802.3af or IEEE
802.3at compliant PSE (Power Sourcing Equipment) for PoE
(Power over Ethernet) devices.
Grounding the AWK-3131A
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.
The
potential difference
between any two
grounding points
must be zero. If the potential
difference is NOT zero, the product could be permanently
damaged.
Installations with Cable Extended Antennas for Outdoor
Applications
If an AWK device or its antenna is installed in an outdoor location, proper
lightning protection is required to prevent direct lightning strikes to the
AWK device. In order to prevent the effects of 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.

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 wire size range of
12
-28 AWG (3.31-0.0804 mm²) and a torque value of 4.5 lb-in
(0.51 Nm).
ATTENTION
If the AWK
-
3131A is connected to a motor or other similar type of
equipment, be sure to use power isolation protection. Before
connecting the
AWK-3131A to the DC power inputs, make sure
the DC power source voltage is stable.
Wiring the Relay Contact
The AWK-3131A has one relay output, which consists of the two contacts
of the terminal block on the AWK-3131A’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. These relay contacts are used to indicate
user-configured events. The two wires attached to the Relay contacts
form an open circuit when a user-configured event is triggered. If a
user-configured event does not occur, the Relay circuit will be closed.

Wiring the Digital Inputs
The AWK-3131A has two sets of digital inputs—DI1 and DI2. Each DI
comprises two contacts of the 10-pin terminal block connector on the
AWK-3131A’s top panel. Refer to the “Wiring the Redundant Power Inputs”
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.
Cable Holder Installation
Attach the cable holder to the bottom of the AWK-3131A to keep cabling
neat and avoid accidents that result from untidy cables.
STEP 1: Screw the cable holder onto the bottom
of the AWK
-3131A.
STEP 2:
After mounting the AWK-
3131A and plugging in the LAN cable,
tighten the cable along the device and wall.
Communication Connections
10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on the AWK-3131A’s front panel are
used to connect to Ethernet-enabled devices.
