Quick Installation Guide

Moxa AirWorks

Fourth Edition, December 2010

Overview

Moxa’s AWK-3121 Access Point/Bridge/AP 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-3121 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-3121 a convenient yet reliable solution for any industrial

wireless application.

Installation and Configuration

Before installing the AWK-3121, make sure that all items in the Package

Checklist are in the box. In addition, you will need access to a notebook

computer or PC equipped with an Ethernet port. The AWK-3121 has a

default IP address that you must use when connecting to the device for

the first time.

Step 1: Select the power source

The AWK-3121 can be powered by a DC power input or PoE (Power over

Ethernet). The AWK-3121 will use whichever power source you choose.

Step 2: Connect the AWK-3121 to a notebook or PC

Since the AWK-3121 supports MDI/MDI-X auto-sensing, you can use

either a straight-through cable or crossover cable to connect the

AWK-3121 to a computer. If the LED indicator on the AWK-3121’s LAN

port lights up, it means the connection is established.

Step 3: Set up the computer’s IP address

Set an IP address on the same subnet as the AWK-3121. Since the

AWK-3121’s default IP address is 192.168.127.253, and the subnet mask

is 255.255.255.0, you should set the IP address of the computer to

192.168.127.xxx and subnet mask to 255.255.255.0.

Step 4: Use the web-based manager to configure

AWK-3121

Open your computer’s web browser and then type

http://192.168.127.253 in the address field to access the homepage

of the web-based management. Before the homepage opens, you will

need to enter the user name and password. For first-time configuration,

enter the default user name and password and then click on the Login

button:

User name: admin

Password: root

ATTENTION

For security reasons, we strongly recommend changing the

password. To do so, select Maintenance Password, and then

follow the on-screen instructions.

Step 5: Select the operation mode for the AWK-3121

By default, the AWK-3121’s operation mode is set to AP. You can change

the setting in Wireless Settings Basic Wireless Settings if you

would like to use the Client mode.

NOTE To make the change effective, you must click Save Configuration

to save the change or Restart ( Save and Restart button to apply

all changes.

Step 6: Test communications

We will describe two test methods. Use the first method if you are using

only one AWK-3121, and use the second method if you are using two or

more AWK-3121s.

Testing method for one AWK-3121

If you are only using one AWK-3121, you will need a second notebook

computer (B) equipped with a WLAN card. Configure the WLAN card to

connect to the AWK-3121 (the default SSID is MOXA) and change the IP

address of notebook B so that it is on the same subnet as the first

notebook (A), which is connected to the AWK-3121.

After configuring the WLAN card, establish a wireless connection with the

AWK-3121 and open a DOS window on notebook B. At the prompt, type

ping IP address of notebook A

and then press the Enter key. A “Reply from IP address …” response

means the communication was successful. A “Request timed out.”

response means the communication failed. In this case, recheck the

configuration to make sure the connections are correct.

Testing method for two or more AWK-3121s

If you have two or more AWK-3121s, you will need a second notebook

computer (B) equipped with an Ethernet port. Use the default settings for

- 3 -

the first AWK-3121 connected to notebook A, and change the second or

third AWK-3121 connected to notebook B to Client mode and then

configure the notebooks and AWK-3121s properly.

After setting up the testing environment, open a DOS window on

notebook B. At the prompt, type

ping IP address of notebook A

and then press Enter key. A “Reply from IP address …” response means

the communication was successful. A “Request timed out.” response

means the communication failed. In this case, recheck the configuration

to make sure the connections are correct.

Mounting the AWK-3121 to a wall requires 4 screws.

Use the AWK-3121 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 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.

Wiring Requirements

WARNING

Safety First!

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

wiring your Moxa AWK-3121.

- 6 -

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.

•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, minimum

6 W (12 V/0.494 A to 48V/0.121 A), 25°C.

ATTENTION

Make sure the external power adaptor (includes power cords and

plug assemblies) provided with the unit is certified and suitable

for use in your country.

Grounding the 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 two pairs of contacts of the 10-contact terminal block connector

on the AWK-3121’s top panel are used for the AWK-3121’s two DC inputs.

Top and front views of the terminal block connector is 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-3121’s top

panel.

ATTENTION

Before connecting the AWK-3121

to the DC power inputs, make

sure the DC power source voltage is stable.

Wiring the Relay Contact

The AWK-3121 has one relay output, which consists of the two contacts of

the terminal block on the AWK-3121’s top panel. Refer to the previous

section for detailed instructions on how to connect the wires to the

terminal block connector, and how to attach the terminal block connector

to the terminal block receptor. These relay contacts are used to indicate

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.

Wiring the Digital Inputs

The AWK-3121 has two sets of digital input—DI1 and DI2. Each DI

comprises two contacts of the 10-pin terminal block connector on the

AWK-3121’s top panel. You can refer to the “Wiring the Redundant Power

Inputs” section for detailed instructions on how to connect the wires to

the terminal block connector, and how to attach the terminal block

connector to the terminal block receptor.

Cable Holder Installation (Optional)

You can attach the cable holder to the bottom of the AWK-3121. This

helps to keep cabling neat and avoid accidents that result from untidy

cables.

STEP 1: Screw the cable holder onto the bottom

of the AWK-3121.

STEP 2: After mounting the AWK-3121 and plugging in the LAN cable,

tighten the cable along the device and wall.
