Relay (Digital Output)

The AWK-5222 has one relay output, which consists of the 2 terminal block contacts on the top

panel, as shown below. These relay contacts are used to forward system failure and

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 remain closed. For safety

reason, the relay circuit is kept open when the AWK-5222 is not powered.

The AWK-5222’s relay status is summarized as follows:

Chapter 2 Getting Started

This chapter explains how to install Moxa’s AirWorks AWK-5222 for the first time, and quickly

set up your wireless network and test whether the connection is running well. With the function

guide, you can find out the functions you need easily.

In this chapter, we cover the following topics:

 First-time Installation and Configuration

 Communication Testing

 Function Guiding Map

AWK-5222 User’s Manual Getting Started

2-2

First-time Installation and Configuration

Before installing the AWK-5222, 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-5222 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-5222 can be powered by DC power input or PoE (Power over Ethernet). The

AWK-5222 will use whichever power source you choose.

NOTE: The ITE unit is to be connected only to PoE networks without routing to the outside

plant.

Step 2: Connect the AWK-5222 to a notebook or PC.

Since the AWK-5222 supports MDI/MDI-X auto-sensing, you can use either a straight-through

cable or crossover cable to connect the AWK-5222 to a computer. If the LED indicator on

AWK-5222’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-5222. Since the AWK-5222’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.

NOTE

After you select Maintenance Æ

ÆÆ Load Factory Default and click the Submit button, the

AWK-5222 will be reset to factory default settings and the IP address will be also reset to

192.168.127.253.

AWK-5222 User’s Manual Getting Started

Step 4: Use the web-based manager to configure AWK-5222

Open your computer’s web browser and type http://192.168.127.253 in the address field to access

the homepage of the web-based Network Manager. Before the homepage opens, you will need to

enter the user name and password as shown in the following figure. For first-time configuration,

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

NOTE

Default user name and password:

User Name: admin

Password: root

For security reasons, we strongly recommend changing the default password. To do so, select

Maintenance > Password, and then follow the on-screen instructions to change the password.

NOTE

After you click Submit to apply changes, you can see that the web page is refreshed, and the

string “(Update)” and a blinking reminder will be shown on the upper-right corner of web page,

as follow.

To make the changes effective, click Restart and then Save and Restart after you change the

settings. About 30 seconds are needed for the AWK-5222 to complete its restart process.

Step 5: Select the operation mode for the AWK-5222.

By default, the AWK-5222’s operation mode is set to Wireless redundancy. You can change the

setting in Wireless Settings Æ

ÆÆ Operation mode if you would like to use the Wireless bridge or

AP-Client mode instead. Detailed information about configuring the AWK-5222’s operation can

be found in Chapter 3.

Step 6: Test communications.

We will describe 2 test methods to make sure the network connection has been established. Please

refer to the following section for more details.

Communication Testing

After installation, you can run a sample test to make sure the AWK-5222 and wireless connection

are functioning normally. Two testing methods are explained in the following sections. Use the

first method if you are using only one AWK-5222 device, and use the second method if you are

using two or more AWK-5222s.

Testing Method for one AWK-5222

If you are only using one AWK-5222, you will need a second notebook computer equipped with a

WLAN card. Conﬁgure the WLAN card to connect to the AWK-5222 (NOTE: the default SSID is

MOXA_1), and change the IP address of the second notebook (B) so that it is on the same subnet

as the first notebook (A), which is connected to the AWK-5222.

After configuring the WLAN card, establish a wireless connection with the AWK-5222 and open a

DOS window on Notebook B. At the prompt, type

ping <IP address of notebook A>

and then press Enter (see the figure below). 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.

AWK-5222 User’s Manual Getting Started

2-5

Testing Method for two or more AWK-5222s

If you have two or more AWK-5222s, you will need a second notebook computer (B) equipped

with an Ethernet port. Use the default settings for the first AWK-5222 connected to notebook A

and change the second or third AWK-5222 connected to notebook B to Client mode. Then,

configure the notebooks and AWK-5222s 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. 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.

Wireless Settings

The essential settings for wireless networks are presented in this function group. Settings must be

properly set before establishing your wireless network.

Operation Mode

The AWK-5222 supports three operation modes that are used for different wireless network

applications:

Wireless Redundancy

In traditional architectures, most vendors only provide a single RF AP and Client, in which the AP

connects one or more Clients to the network. Since the AP and Client are connected by a single RF

connection, if the RF connection is disconnected the system or network behind the Client will be

disconnected, too.

AWK-5222 User’s Manual Other Console Configurations

3-9

With the new wireless redundancy technology, you can set up a redundant wireless connection

between a redundant client device and a redundant AP device. The redundant structure involves

using the AWK-5222’s two RF modules to set up two independent wireless connections between

the redundant client and redundant AP devices. If either of the two wireless connections fails,

the other wireless connection will continue transmitting packets between the redundant client and

redundant AP devices. In addition to carrying one or more redundant clients, standard single RF

clients can also associate with the redundant AP. One of the biggest advantages of the

AWK-5222’s wireless redundancy mode is that you can expect “zero data loss.”

AWK-5222 User’s Manual Other Console Configurations

3-11

Wireless Bridge

A bridge is a network component that connects two networks. AWK-5222’s bridge operation is

based on the AP (master) and Client (Slave) concept. Both sides of the connection must have the

same RF type, SSID, and security settings.

For single RF mesh networks, we can use WDS to establish a static bridge link. In this case, the

APs at both ends of the WDS link must be configured manually with each other’s MAC addresses.

The performance of a single RF bridge will be poor if more nodes are added.

The AWK-5222’s dual RF bridge concept is different from using a single RF, because the

AWK-5222 has dual RFs, and offer users a cascade link to bridge the two ends without narrowing

down the throughput.

are available in AWK-5222 by selecting Security mode and WPA type:

y Open: No authentication, no data encryption.

y WEP: Static WEP (Wired Equivalent Privacy) keys must be manually configured.

y WPA/WPA2-Personal: also known as WPA/WPA2-PSK. You need to specify the Pre-Shared

Key in the Passphrase field, which will be used by the TKIP or AES engine as a master key to

generate keys that actually encrypt outgoing packets and decrypt incoming packets.

y WPA/WPA2-Enterprise: also called WPA/WPA2-EAP (Extensible Authentication Protocol).

In addition to device-based authentication, WPA/WPA2-Enterprise enables user-based

authentication via IEEE802.1X. The AWK-5222 can support three EAP methods: EAP-TLS,

EAP-TTLS, and EAP-PEAP.

Security mode

Setting Description Factory Default

Open No authentication

WEP Static WEP is used

WPA WPA is used

WPA2 Fully supports IEEE802.11i with

“TKIP/AES + 802.1X”

Open

For security reasons, it is highly recommended that the security mode should be set to the options

other than Open System. When the security mode is set to Open System, no authentication or data

encryption will be performed.

WEP

According to the IEEE802.11 standard, WEP can be used for authentication and data encryption

(confidentiality). Shared (or Shared Key) authentication type is used if WEP authentication and

data encryption are both needed. Normally, Open (or Open System) authentication type is often

used when WEP data encryption is run with authentication.

When WEP is enabled as a security mode, the length of a key (so-called WEP seed) can be

specified as 64/128 bits, which is actually a 40/104-bit secret key with a 24-bit initialization vector.

The AWK-5222 provides 4 entities of WEP key settings that can be selected to use with Key index.

The selected key setting specifies the key to be used as a send-key for encrypting traffic from the

AP side to the wireless client side. All 4 WEP keys are used as receive-keys to decrypt traffic from

the wireless client side to the AP side.

The WEP key can be presented in two Key type, HEX and ASCII. Each ASCII character has 8 bits,

so a 40-bit (or 64-bit) WEP key contains 5 characters, and a 104-bit (or 128-bit) key has 13

characters. In hex, each character uses 4 bits, so a 40-bit key has 10 hex characters, and a 128-bit

key has 26 characters.
