DIN-Rail Mounting
The aluminum DIN-Rail attachment plate should be fixed to the back panel of
AWK-3121 when you take it out of the box. If you need to reattach the
DIN-Rail attachment plate to AWK-3121, 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 AWK-3121 from the DIN-Rail, simply reverse Steps 1 and 2 above.
WallMounting(Optional)
For some applications, you will find it convenient to mount AWK-3121 on the
wall, as illustrated below.
STEP 1 :
Remove the aluminum DIN-Rail attachment plate from AWK-3121, and then
attach the wall mount plates, as shown in the diagrams below.

Bottom

STEP 2 :
Mounting AWK-3121 on the wall requires 4 screws. Use the
AWK-3121, 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.
6.0 mm
3.5 mm
- 5 -

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 in the wall, insert the four screw heads through the
large parts of the keyhole-shaped apertures, and then slide AWK-3121
downwards, as indicated below. Tighten the four screws for added stability.
Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your MOXA AWK-3121.
ATTENTION
Safety First!
Calculate the maximum possible current in each power wire
and common wire. Observe all electrical codes dictating the
maximum current allowable for each wire size.
If the current goes above the maximum ratings, the wiring
could overheat, causing serious damage to your equipment.

Grounding MOXA AWK-3121
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 top twopairsof contacts of the 10 -contact terminal block connector on
AWK-3121’s top panel are used for AWK-3121’s two DCinputs. Top and front
views of one of the terminal block connectors are shownhere.
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.
Top View
STEP 3 : Insert the plastic terminal block connector
prongs into the terminal block receptor, which is
located on AWK-3121’s top panel.
Front View
ATTENTION
Before connecting AWK-3121 to theDCpower inputs,
make surethe DC power source voltage is stable.

Communication Connections
10/100BaseT(X) Ethernet PortConnection
The 10/100BaseT(X) ports located on AWK-3121’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
AWK-3121 has one RS-232 (8-pin RJ45) console port, located on the side
panel.Use either an RJ45-to-DB9 or RJ45-to-DB25 cable to connect MOXA
AWK-3121’s console port to your PC’s COM port. You may then use a
consoleterminal program to access AWK-3121 for console c onfiguration.

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-pin RJ45 connectors
(andports) are typically not labeled on the connector (or port).
Refer tothe Pinout diagram below to see how RJ45 pins are
numbered.

FEDERAL COMMUNICATIONS COMMISSION INTERFERENCE STATEMENT
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 party responsible for
compliance could void the user's authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions:
(1) This device may not cause harmful interference and
(2) This device must accept any interference received, including interference that may
cause undesired operation.
FCC RF Radiation Exposure Statement
This equipment must be installed and operated in accordance with provided instructions
and the antenna(s) used for this transmitter must be installed to provide a separation
distance of at least 20 cm from all persons and must not be co-located or operating in
conjunction with any other antenna or transmitter. End-users and installers must be
provide with antenna installation instructions and transmitter operating conditions for
satisfying RF exposure compliance.
