Overview

Moxa’s AWK-1127 WLAN client is ideal for applications that are hard to

wire, too expensive to wire, or use mobile equipment that connects over

a TCP/IP network. The AWK-1127 is rated to operate at temperatures

ranging from 0 to 60°C for standard models and -40 to 75°C for extended

temperature models, and is rugged enough for any harsh industrial

environment. Installation is easy, with either DIN-rail mounting or

distribution boxes. The DIN-rail mounting ability, wide operating

temperature range, and IP30 housing with LED indicators make the

AWK-1127 a convenient yet reliable solution for any industrial wireless

application.

Mounting Dimensions (unit = mm)

DIN-Rail Mounting

The aluminum DIN-rail attachment plate should be fixed to the back panel

of the AWK-1127 when you take it out of the box. If you need to reattach

the DIN-rail attachment plate to the AWK-1127, 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 the AWK-1127 from the DIN rail, simply reverse Steps 1 and 2.

- 5 -

Wall Mounting (optional)

For some applications, it may be more convenient to mount the

AWK-1127 to a wall, as illustrated below:

STEP 1:

Remove the aluminum

DIN

-rail attachment plate

from the

AWK-1127, and

then attach the

wall mount

plates with M3 screws, as

shown in the adjacent

diagrams.

STEP 2:

Mounting the

AWK-1127 to a wall requires 4 screws.

Use the

AWK-1127 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

shafts should be less

than 3.5 mm in diameter, as shown in the figure at the

right.

Do not drive the screws in all the way into the wall—leave a space of about

2 mm to allow room for sliding the wall-mount panel between the wall and

the screws.

NOTE

Test the screw head and shank size by inserting the screws into

one of the keyhole shaped apertures of the

wall-mounting p

lates

before attaching the plate to 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-1127

downwards, as indicated to the

right. Tighten the four screws for

added stability.

Wiring Requirements

WARNING

Safety First!

Be sure to disconnect the power cord before installing and/or

wiring your Moxa AWK-1127.

WARNING

Safety First!

Calculate the maximum possible current in each power wire and

common wire. Observe all electrical codes dictating the

maximum current allowed 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. note content

here.

•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.

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, 0.16 to

0.55 A

ATTENTION

Make sure

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-1127

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.

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

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.

Wiring the Redundant Power Inputs

The 4-contact terminal block connector on the AWK-1127’s top panel is

used for the AWK-1127’s two DC inputs. The top and front views of the

terminal block connector are shown here.

Top View

Front View

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.

STEP 3:

Insert the plastic terminal block

connector prongs into the terminal block

receptor,

which is located on the AWK-1127’s t

panel.

ATTENTION

Before connecting the

AWK-1127

to the DC power inputs, make

sure the DC power source voltage is stable.

Communication Connections

10/100BaseT(X) Ethernet Port Connection

The 10/100BaseT(X) ports located on the AWK-1127’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 Console Connection

The AWK-1127 has one RS-232 (8-pin RJ45) console port located on the

top panel. Use either an RJ45-to-DB9 or RJ45-to-DB25 cable to connect

the Moxa AWK-1127’s console port to your PC’s COM port. You may then

use a console terminal program to access the AWK-1127 for console

configuration.
