Overview
Moxa’s AWK-1121 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-1121 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-1121 a convenient yet reliable solution for any industrial wireless
application.

Mounting Dimensions
DIN-Rail Mounting
The aluminum DIN-Rail attachment plate should be fixed to the back
panel of the AWK-1121 when you take it out of the box. If you need to
reattach the DIN-Rail attachment plate to the AWK-1121, 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-1121 from the DIN-Rail, simply reverse Steps 1 and
2.

Wall Mounting (optional)
For some applications, it may be more convenient to mount the
AWK-1121 to a wall, as illustrated below.
STEP 1:
Remove the aluminum
DIN
-Rail attachment plate
from the
AWK-1121, and
then attach the
wall mount
plates with M3 screws, as
shown in the adjacent
diagrams.
STEP 2:
Mounting the
AWK-1121 to a wall requires 4 screws.
Use the
AWK-1121 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
-1121 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-1121.
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-1121
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-1121’s top panel is
used for the AWK-1121’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-1121’s t
op
panel.
ATTENT
ION
Before connecting the
AWK-1121
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-1121’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.

RS-232 Connection
The AWK-1121 has one RS-232 (8-pin RJ45) console port located on the
top panel. Use either an RJ45-to-DB9 or RJ45-to-DB25 cable to connect
the Moxa AWK-1121’s console port to your PC’s COM port. You may then
use a console terminal program to access the AWK-1121 for console
configuration.

NOTE
1.
The pin numbers for male DB9 and DB25 connectors, and
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-p
in RJ45 connectors
(and ports) are typically not labeled on the connector (or
port). Refer to the Pinout diagram above to see how RJ45
pins are numbered.
