Attaching Antennas
The AWK-6232-M12 inclues two dual-band omnidirectional antenna by
default. Attach the antennas as illustrated below.
Step 1: Use your fingers and hold the antenna metal N-type connector.
Screw the antenna N-type connector (male) onto the
-6232-M12 device’s N-type connector (female)
Do not hold the rubber plate to screw the antenna on to the
AWK

Use the antennas correctly: Use 2.4GHz antennas if the
AWK
-6232-M12 operates in IEEE 802.11b/g/n. Use the 5GHz
antennas for operations in IEEE
802.11a/n. 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-6232-M12 on the wall, as illustrated
below.
with M4 screws, as shown in
the diagram below.
wall requires 4 screws. Use the
AWK

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
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.
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-6232-M12 downwards, as indicated to the right. Tighten
the four screws for added stability.

To avoid environmental vibration or shock, you can consider a
robust ins
tallation with four bigger screws, which the shafts are
between 7.0 mm and 8.5 mm in diameter, and fix the
AWK-6232-M12 onto wall directly and tightly.

Wiring Requirements
Be sure to disconnect the power cord before installing and/or
wiring your Moxa
Calculate the maximum possible current in each power wire and
common wire. Observe all electrical codes d
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-6232-M12
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
face, 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-6232-M12 must be connected to a Power over Ethernet Plus
(PoE+) IEEE 802.3at compliant power source or an IEC60950 compliant

limited power source. When AWK-6232-M12 is powered via DC power,
the M12 A-coding connector on the bottom panel is used for the
AWK-6232-M12’s two redundant inputs. The male, device-side pin
assignment is shown below:
Pin Power Input
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
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-6232-M12 to the DC power inputs,
make sure the DC power source voltage is stable.
the PoE Injector. Instead, please use an
IEEE802.3af
or IEEE802.3at
compliant PSE (Power Sourcing Equipment) for
PoE+ (Power over Ethernet Plus) devices.
Wiring the Digital Inputs and Relay Contact
(Digital Output)
The AWK-6232-M12 has two sets of digital input—DI1 and DI2. Each DI
comprises two contacts of the 8-pin M12 connector on the
AWK-6232-M12’s bottom panel. These two digital inputs can be
connected to digital-output-enabled sensors for on-site status
monitoring.
The AWK-6232-M12 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-8PF-IP67, is recommended for
connecting the AWK-6232-M12’s DIs and relay.
Communication Connections
Connecting the Data Lines
10/100/1000BaseT(X) Ethernet Port Connection
AWK-6232-M12 has 10/100/1000BaseT(X) Ethernet ports (8-pin
shielded M12 connector with A coding). The 10/100/1000BaseT(X) ports
located on the AWK-6232-M12’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.

3. Test the plug to ensure the quality.
RS-232 Connection
The AWK-6232-M12 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-6232-M12’s console port to your PC’s COM port.
You may then use a console terminal program to access the
AWK-6232-M12 for console configuration.

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-
(and ports) are typically not labeled on the connector (or
port). Refer to the Pinout diagram above to see how RJ45
pins are numbered.
For railway rolling stock applications, AWK
must use a galvanically isolated power supply that is compliant
with the EN 50155 standard.

The front panel of the Moxa AWK-6232-M12 contains several LED
indicators. The function of each LED is described in the table below.
