Overview

The AWK-4121 outdoor wireless Access Point is an ideal solution for

industrial applications that are hard to wire, too expensive to wire, or use

mobile equipment that connect to a TCP/IP network. The AWK-4121 is

rated to operate at temperatures ranging from -40 to 75°C, and its

dust-tight and weatherproof design is IP68-rated. An IP68 rating means

the device is completely protected from dust and is protected against the

effects of immersion in water between 15cm and 1m in depth. This means

you can set up a WLAN or extend existing wired networks to outdoor

locations and still maintain a reliable connection. The AWK-4121 has two

redundant DC power inputs for increased reliability, can be powered via

PoE (discontinued starting with HW Rev 2.0.0), and is easy to deploy.

Dimensions (unit = mm)

Attaching Antennas

The AWK-4121 includes 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)

Caution

Do not hold the rubber plate to screw the antenna on to

the

AWK-4121 device.

ATTENTION

Use the antennas correctly: Use 2.4

GHz antennas if the

AWK

-4121 operates in IEEE 802.11b/g. Use the 5

GHz 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.

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.

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 o

n 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 differen

ce between two ground potentials, otherwise

there is a risk that the device could be destroyed.

Installations with Unstable Power Inputs

There are cases where the device has to be wired to the same power

source as other equipment. In such cases if equipment such as motors

that are connected in the circuit draw a large amount of current during

operation, the transient voltage drop could potentially cause the AWK to

become unstable. Installing a DC/DC power isolator in between the two

equipment is recommended to isolate the transient effect and to ensure a

- 8 -

stable power input for the AWK.

Installations with 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.

•SA-NFNF-01: Surge arrester, N-type (female) to N-type (female)

Wiring the Redundant Power Inputs

The AWK-4121 must be connected to a power-over-Ethernet (PoE

discontinued starting with HW Rev 2.0.0) 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 Adapter (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.

Communication Connections

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.
