Attaching Antennas
The AWK-4121 inclues two dual-band omni-directional antenna by
default. Attach the antennas as illustrated below.
Step 1: Use your fingers and hold the antenna metal N-type connector.
Step 2: Screw the antenna N-type connector (male) onto the AWK-4121
device’s N-type connector (female)
Antenna Metal N-type
Rubber plate
Caution
Do not hold the rubber plate to screw the antenna on to the
AWK-4121 device.
ATTENTION
Use the antennas correctly: Use 2.4GHz antennas if the
AWK-4121 operates in IEEE 802.11b/g. Use the 5GHz antennas
for operations in IEEE802.11a. Make sure your antenna
installation is within a safe area covered by a lightning protection
or surge arrest system.

Wall Mounting
In most applications, wall mount provides an easier installation. You will
find it quite easy to mount AWK-4121 on the wall, as illustrated below.
STEP 1:
Attach the wall-mounting kit
with M4 screws, as shown in
the diagram below.
STEP 2:
Mounting the AWK-4121 on the wall
requires 4 screws. Use the AWK-4121
device, with wall-mounting kit
attached, as a guide to mark the correct
locations of the 4 screws. The heads of
the screws are recommended to be
between 5.5mm and 8.5 mm in
diameter, and the shafts should not be
more than 5.0 mm
in diameter, as
shown in the figure.
5.5 - 8.5 mm
< 5.0 mm
Do not screw the screws all the way in to the wall—leave a space of about
2 mm to allow room for sliding the wall-mounting kit between the wall and
the screws.
ATTENTION
You can 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-4121 downwards, as indicated to the right. Tighten the
four screws for added stability.
⇒
ATTENTION
To avoid environmental vibration or shock, you can consider a
robust installation with four bigger screws, which the shafts are
between 7.0 mm and 8.5 mm in diameter, and fix the AWK-4121
onto wall directly and tightly.
- 5 -

DIN-Rail Mounting (Optional)
The DK-DC50131 die-cast metal kit can be
bought separately, and enable easy and
robust installation for the AWK-4121. A pair
of DK-DC50131s is needed for DIN-Rail
mounting. To install the DIN-Rail mounting
kits, tightly attach the two DIN-Rail
mounting kits on the rear panel of AWK-4121
with 12 screws. (6 screws for each kit)
To Install
STEP 1:
Use the recessed button
on the spring-loaded
bracket to lock it into
position.
STEP 2:
Insert the top of the DIN-Rail into the slot
just below the upper hook of the DIN-Rail
mounting kit. Push the AWK-4121 toward
the DIN-Rail until the DIN-Rail attachment
bracket snaps into place.
To Release
STEP 1:
Pull out the two spring-loaded
brackets from the bottom until
they are fixed in the “release”
position.
STEP 2:
Pull the AWK-4121 out and upward.

Wiring Requirements
WARNING Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your Moxa AWK-4121.
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.
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.
Grounding Moxa AWK-4121
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. There must be no
potential difference between two ground potentials, otherwise
there is a risk that the device could be destroyed.
Wiring the Redundant Power Inputs
The AWK-4121 must be connected to a power-over-Ethernet (PoE) IEEE
802.3af compliant power source or an IEC60950 compliant limited power
source. When AWK-4121 is powered via DC power, the M12 A-coding
connector on the bottom panel is used for the AWK-4121’s two redundant
inputs. The pin assignment is shown below:

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
6 W (12 V/0.494 A to 48V/0.121 A, 25°C).
Make sure External Power Adaptor (includes power cords and
plug assemblies) provided with the unit is certified and suitable
for use in your country.
Before connecting the AWK-4121 to the DC power inputs, make
sure the DC power source voltage is stable.
Wiring the Digital Inputs and Relay Contact
(Digital Output)
The AWK-4121 has two sets of digital input—DI1 and DI2. Each DI
comprises two contacts of the 8-pin M12 connector on the AWK-4121’s
bottom panel. These two digital inputs can be connected to
digital-output-enabled sensors for on-site status monitoring.
The AWK-4121 also has one relay output, which consists of the two
contacts. These relay contacts are used to detect 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.
A field-installable plug, M12A-8PMM-IP68, is recommended for
connecting the AWK-4121’s DIs and relay.

10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on the AWK-4121’s bottom 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-4121 has one RS-232 (8-pin RJ45) console port located on the
bottom panel. Use either an RJ45-to-DB9 or RJ45-to-DB25 cable to
connect the Moxa AWK-4121’s console port to your PC’s COM port. You
may then use a console terminal program to access the AWK-4121 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-pin 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.
ATTENTION
To ensure the IP68-rated connectivity, you must use a
waterproof housing during any communication activities. An
IP68-rated field installable plug, which is attached in AWK-4121’s
accessory pack, may be needed in this case. The installation
guide is shown below:
