Overview
The AWK-1137C industrial Wi-Fi client 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-1137C combines two adjacent 20 MHz channels into a single 40 MHz
channel to deliver a potent combination of greater reliability and more
bandwidth. The AWK-1137C can operate on either the 2.4 or the 5 GHz
band and is backward compatible with existing 802.11a/b/g
deployments.
Hardware Setup
This section covers the hardware setup for the AWK-1137C.

Mounting Dimensions
Unit = mm (inch)
DIN-Rail Mounting
The aluminum DIN-rail attachment plate comes attached to the back
panel of the AWK-1137C when you take it out of the box. If you need to
reattach the DIN-rail attachment plate to the AWK-1137C, 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

Wall Mounting (Optional)
For some applications, it may be more convenient to mount the
AWK-1137C to a wall, as illustrated below:
STEP 1:
Remove the aluminum

shown in the adjacent
diagrams.
AWK-1137C to a wall requires two
the AWK-1137C device, with
plates attached, as a guide to mark the
correct locations of the
two 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.
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 3a:
Once the screws are fixed into the wall,
insert the
screw heads through the
large opening of the keyhole
apertures, and then slide the
AWK
-1137C downwards, as indicated
to the right. Tighten the
screws for
added stability.
STEP 3b:
Alternatively, insert four screws

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.
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.

Grounding the Moxa AWK-1137C
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.

mounting surface, such as a metal panel.

otherwise, there is a risk that the device could be destroyed.
Installing 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.

This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses,
and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will
not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
- Consult the dealer or an experienced radio/ TV technician for help.

CAUTION: Any changes or modifications not expressly approved
by the grantee of this device could void the user's authority to
operate the equipment Type message content here.

Software Setup
This section covers the software setup for AWK models in general.
How to Access the AWK
Before installing the AWK device (AWK), make sure that all items in the
package checklist are provided in the product box. You will also need
access to a notebook computer or PC equipped with an Ethernet port.
• Step 1: Select a suitable power source and plug in the AWK.
The AWK can be powered by DC power ranging from 12 VDC to 48
VDC.
• Step 2: Connect the AWK to the notebook or PC via the AWK’s
LAN port.
The LED indicator on the AWK’s LAN port will light up when a
connection is established.
If you are using an Ethernet-to-USB adapter, follow the
instructions in the user’s manual provided with the adapter.

• Step 3: Set up the computer’s IP address
Choose an IP address for the computer that is on the same subnet as
the AWK. Since the AWK’s default IP address is 192.168.127.253,
and the subnet mask is 255.255.255.0, set the IP address to
192.168.127.xxx, where xxx is a value between 1 and 252.
• Step 4: Access the homepage of the AWK.
Open your computer’s web browser and type
http://192.168.127.253 in the address field to access the AWK’s
homepage. Log in using the following default username and
password:
Default Username: admin
Default Password: moxa
