Installation and Configuration
Before installing the AWK-5222, make sure that all items in the Package
Checklist are in the box. In addition, you will need access to a notebook
computer or PC equipped with an Ethernet port. The AWK-5222 has a
default IP address that you must use when connecting to the device for
the first time.
Step 1: Select the power source
The AWK-5222 can be powered by a DC power input or PoE (Power over
Ethernet). The AWK-5222 will use whichever power source you choose.
Step 2: Connect the AWK-5222 to a notebook or PC
Since the AWK-5222 supports MDI/MDI-X auto-sensing, you can use
either a straight-through cable or crossover cable to connect the
AWK-5222 to a computer. If the LED indicator on the AWK-5222’s LAN
port lights up, it means the connection is established.
Step 3: Set up the computer’s IP address
Set an IP address on the same subnet as the AWK-5222. Since the
AWK-5222’s default IP address is 192.168.127.253, and the subnet mask
is 255.255.255.0, you should set the IP address of the computer to
192.168.127.xxx and subnet mask to 255.255.255.0.

DIN-Rail Mounting
The aluminum DIN-Rail attachment plate should be fixed to the back
panel of the AWK-5222 when you take it out of the box. If you need to
reattach the DIN-Rail attachment plate to the AWK-5222, 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 attachment unit will
snap into place as shown below.
To remove the AWK-5222 from the DIN-Rail, simply reverse Steps 1 and
2.
Wall Mounting (optional)
For transportation applications that require an EN50155 certification
report, you should purchase the optional wall mount for the AWK-5222,
since the wall mount has passed EN50155 testing. The wall mount is also
convenient for other applications that require mounting the AWK-5222 to
a wall.
STEP 1:
Remove the aluminum
DIN
then attach the wall mount
plates with
shown in the adjacent
diagrams.
-5222 to a wall requires 4 screws.
-5222 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
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.

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
downwards, as indicated to the
right. Tighten the four screws for
added stability.
Be sure to disconnect the power cord before in
wiring your Moxa AWK-5222.
Calculate the maximum possible current in each power wire and
common wire. Observe all electrical codes dictating the
maximum current allow
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.

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,
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-5222
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.
This product is intended to
be mounted to a well-grounded
mounting surface, such as a metal panel.
Wiring the Redundant Power Inputs
The top two pairs of contacts of the 10-contact terminal block connector
on the AWK-5222’s top panel are used for the AWK-5222’s two DC inputs.

Wiring the Relay Contact
The AWK-5222 has one relay output, which consists of the two contacts of
the terminal block on the AWK-5222’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-5222 has two sets of digital input—DI1 and DI2. Each DI
comprises two contacts of the 10-pin terminal block connector on the
AWK-5222’s top panel. You can 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 (Optional)
You can attach the cable holder to the bottom of the AWK-5222. This
helps to keep cabling neat and avoid accidents that result from untidy
cables.
Screw the cable holder onto the bottom of the
AWK
After mounting the AWK-5222 and plugging in the LAN cable, tighten the
cable along the device and wall.
