Overview
Moxa’s AWK-1127 WLAN Client is ideal for applications that are hard to
wire, too expensive to wire, or use mobile equipment that connects over
a TCP/IP network. The AWK-1127 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-1127 a convenient yet reliable solution for any industrial wireless
application.

Mounting Dimensions (unit = mm)
DIN-Rail Mounting
The aluminum DIN-Rail attachment plate should be fixed to the back
panel of the AWK-1127 when you take it out of the box. If you need to
reattach the DIN-Rail attachment plate to the AWK-1127, 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-1127 from the DIN-Rail, simply reverse Steps 1 and
2.

- 5 -
Wall Mounting (optional)
For some applications, it may be more convenient to mount the
AWK-1127 to a wall, as illustrated below.
STEP 1:
Remove the aluminum
DIN
-Rail attachment plate
from the
AWK-1127, and
then attach the wall mount
plates with M3 screws, as
shown in the adjacent
diagrams.
STEP 2:
Mounting the
AWK-1127 to a wall requires 4 screws.
Use the
AWK-1127 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 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 into the
wall, insert the four screw heads
through the large opening of the
keyhole
-shaped apertures, and
then slide the
AWK-1127
downwards, as indicated to the
right. Tighten the four screws for
added stability.

Wiring Requirements
WARNING
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your Moxa AWK-1127.
WARNING
Safety First!
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: 12 to 48 VDC
, minimum
7.7 W (12 V/0.55 A to 48V/0.16 A), 25°C.
ATTENTION
Make sure
the external power adapto
r (includes power cords and
plug assemblies) provided with the unit is certified and suitable
for use in your country.

Grounding the Moxa AWK-1127
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 4-contact terminal block connector on the AWK-1127’s top panel is
used for the AWK-1127’s two DC inputs. The top and front views of the
terminal block connector are shown here.
Top View
Front View
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-1127’s t
op
panel.
ATTENTION
Before connecting the
AWK-1127
to the DC power inputs, make
sure the DC power source voltage is stable.
Communication Connections
10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on the AWK-1127’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.

the Moxa AWK-1127’s console port to your PC’s COM port. You may then
use a console terminal program to access the AWK-1127 for console
configuration.

hole numbers for female DB9 and DB25 connectors are
labeled on the connector. However, the numbers are
typically quite small, so you may need to use a magnifying
glass to see the numbers clearly.
2. The pin numbers for both 8-pin and 10-

ATTENTION
The
AWK-1127 is NOT a portable mobile device and should be
located at least 20 cm
away from the human body.
The
AWK-1127 is NOT
designed for the general public. To deploy
AWK
-1127s and establish a wireless network safely, a
well-trained technician is required for installation.
ATTENTION
Use the antennas correctly: The 2.4 GHz antennas are needed
when the
AWK-1127 operates in IEEE 802.11b/g. The 5 GHz
antennas are needed for IEEE802.11a. Make sure your antenna
installation is within a safety area, which is covered by a lightning
protection or surge arrest system.
ATTENTION
This device complies with Part 15 of the FCC rules.
Operation is subject to the following conditions:
1. This device may not cause harmful interference.
2. This device must accept any
interference received,
including interference that may cause undesired operation.
ATTENTION
Do not locate the antenna near overhead power lines or other
electric light or power circuits, or where it can come into contact
with such circuits. When installing the antenna. Take extreme
care not to come into contact with such circuits, because they
may cause serious injury or death. For proper installation and
grounding of the antenna. Please refer to national and local codes
(
for example, U.S.:
NFPA 70, National Electrical Code, Artical810,
and Canada: Canadian Electrical Code, Section 54).
NOTE
For installation flexibility, either the MAIN antenna (on the front
panel) or the AUX antenna (on the top panel) may be selected for
use. Make sure the antenna connection matches the antenna
configured in the
AWK-1121/1127 interface.
To protect the connect
ors and RF module, all radio ports should
be terminated by either an antenna or a terminator. The use of
the resistive terminator for terminating the unused antenna port
is strongly recommended.
