First-time Installation and Configuration

Before installing the AWK-1131A, make sure that all items in the Package Checklist are in the box. You will need

access to a notebook computer or PC equipped with an Ethernet port. The AWK-1131A has a default IP address

that must be used when connecting to the device for the first time.

• Step 1: Select the power source.

The AWK-1131A can be powered by a DC power input. The AWK-1131A will use whichever power source

you choose.

• Step 2: Connect the AWK-1131A to a notebook or PC.

Since the AWK-1131A supports MDI/MDI-X auto-sensing, you can use either a straight-through cable or

crossover cable to connect the AWK-1131A to a computer. The LED indicator on the AWK-1131A’s LAN port

will light up when a connection is established.

• Step 3: Set up the computer’s IP address.

Choose an IP address on the same subnet as the AWK-1131A. Since the AWK-1131A’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.

et to factory default settings and the IP address will be reset to 192.168.127.253.

• Step 4: Use the web-based manager to configure the AWK-1131A

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:

Communication Testing

After installing the AWK-1131A you can run a sample test to make sure the AWK-1131A and wireless

connection are functioning normally. Two testing methods are described below. Use the first method if you are

using only one AWK-1131A device, and use the second method if you are using two or more AWK-1131A units.

How to Test One AWK-1131A

If you are only using one AWK-1131A, you will need a second notebook computer equipped with a WLAN card.

Configure the WLAN card to connect to the AWK-1131A (the default SSID is MOXA), and change the IP address

of the second notebook (Notebook B) so that it is on the same subnet as the first notebook (Notebook A), which

is connected to the AWK-1131A.

After configuring the WLAN card, establish a wireless connection with the AWK-1131A 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.

AirWorks AWK-1131A Getting Started

2-4

How to Test Two or More AWK-1131A Units

If you have two or more AWK-1131A units, you will need a second notebook computer (Notebook B) equipped

with an Ethernet port. Use the default settings for the first AWK-1131A connected to notebook A and change

the second or third AWK-1131A connected to notebook B to Client mode, and then configure the notebooks and

AWK-1131A units 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 LAN Setup

The AWK-1131A provides the AP/client mode for point-to-multipoint communication.

AP/client: The IP-Bridging mechanism is used to overcome limitations of the 802.11 standards. In this case,

the MAC address of the devices connected to the client radio will be replaced with the client’s MAC address.

Under AP/client modes, communication problems might be encountered when you have a MAC authenticated

system or MAC (Layer 2) based communication. In this case, you will need to change the network to use the

master/slave operation mode.

Sniffer: In order to provide an easier way for our customers to analyze wireless traffic, the AWK-1131A

Basic WLAN Setup

The “Basic WLAN Setup” panel is used to add and edit SSIDs. An SSID is a unique identifier that wireless

networking devices use to establish and maintain wireless connectivity. Multiple access points on a network or

sub-network can use the same SSIDs. You can configure your AWK to use up to 9 SSIDs, and configure each

SSID differently. All of the SSIDs are active at the same time; that is, client devices can use any of the SSIDs

to associate with the access point.

WLAN Security Settings

The AWK-1131A provides four standardized wireless security modes: Open, WEP (Wired Equivalent Privacy),

WPA (Wi-Fi Protected Access), and WPA2. Several security modes are available in the AWK-1131A by

selecting Security mode and WPA type:

MOXA

• Open: No authentication, no data encryption.

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

• WPA/WPA2-Personal: Also known as WPA/WPA2-PSK. You will 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.

• 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 IEEE 802.1X.

The AWK-1131A can support three EAP methods: EAP-TLS, EAP-TTLS, and EAP-PEAP.

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 types, 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

WPA/WPA2-Personal

WPA (Wi-Fi Protected Access) and WPA2 provide significant improvements over the WEP encryption method.

WPA is a security standard based on 802.11i draft 3, while WPA2 is based on the fully ratified version of 802.11i.

The initial vector is transmitted, encrypted, and enhanced with its 48 bits, twice as long as WEP. The key is

regularly changed so that true session is secured.

Even though AES encryption is only included in the WPA2 standard, it is widely available in the WPA security

mode of some wireless APs and clients as well. The AWK-1131A also supports AES algorithms in WPA and WPA2

for better compatibility.

Personal versions of WPA/WPA2, also known as WPA/WPA-PSK (Pre-Shared Key), provide a simple way of

encrypting a wireless connection for high confidentiality. A passphrase is used as a basis for encryption

methods (or cipher types) in a WLAN connection. The passphrases should be complicated and as long as

possible. There must be at least 8 ASCII characters in the Passphrase, and it could go up to 63. For security

reasons, this passphrase should only be disclosed to users who need it, and it should be changed regularly.

Before choosing the EAP protocol for your WPA/WPA2-Enterpise settings on the client end, please contact the

network administrator to make sure the system supports the protocol on the AP end. Detailed information on

these three popular EAP protocols is presented in the following sections.

EAP-TLS

TLS is the standards-based successor to Secure Socket Layer (SSL). It can establish a trusted communication

channel over a distrusted network. TLS provides mutual authentication through certificate exchange. EAP-TLS

is also secure to use. You are required to submit a digital certificate to the authentication server for validation,

but the authentication server must also supply a certificate.

You can use Basic WLAN Setup  WLAN Certificate Settings to import your WLAN certificate and enable

EAP-TLS on the client end.

You can check the current certificate status in Current Status if it is available.

• Certificate issued to: Shows the certificate user

• Certificate issued by: Shows the certificate issuer

• Certificate expiration date: Indicates the expiration date of the certificate

EAP-TTLS

It is usually much easier to re-use existing authentication systems, such as a Windows domain or Active

Directory, LDAP directory, or Kerberos realm, rather than creating a parallel authentication system. As a result,

TTLS (Tunneled TLS) and PEAP (Protected EAP) are used to support the use of so-called “legacy authentication

methods.”

TTLS and PEAP work in a similar way. First, they establish a TLS tunnel (EAP-TLS for example), and validate

whether the network is trustworthy with digital certificates on the authentication server. This step establishes

a tunnel that protects the next step (or “inner” authentication), and consequently is sometimes referred to as

“outer” authentication. The TLS tunnel is then used to encrypt an older authentication protocol that

authenticates the user for the network.

As you can see, digital certificates are still needed for outer authentication in a simplified form. Only a small

number of certificates are required, which can be generated by a small certificate authority. Certificate

reduction makes TTLS and PEAP much more popular than EAP-TLS.

The AWK-1131A provides some non-cryptographic EAP methods, including PAP, CHAP, MS-CHAP, and

MS-CHAP-V2. These EAP methods are not recommended for direct use on wireless networks. However, they

might be useful as inner authentication methods with TTLS and PEAP.

DHCP Server (for AP mode only)

DHCP (Dynamic Host Configuration Protocol) is a networking protocol that allows administrators to assign

temporary IP addresses to network computers by “leasing” an IP address to a user for a limited amount of time,

instead of assigning permanent IP addresses.

The AWK-1131A can act as a simplified DHCP server and easily assign IP addresses to your DHCP clients by

responding to the DHCP requests from the client ends. The IP-related parameters you set on this page will also

be sent to the client.

You can also assign a static IP address to a specific client by entering its MAC address. The AWK-1131A

The AWK-1131A includes various filters for IP-based packets going through LAN and WLAN interfaces. You

can set these filters as a firewall to help enhance network security.

MAC Filters

The AWK-1131A’s MAC filter is a policy-based filter that can allow or filter out IP-based packets with specified

MAC addresses. The AWK-1131A provides 8 entities for setting MAC addresses in your filtering policy.

Remember to check the Active check box for each entity to activate the setting.

IP Protocol Filters

The AWK-1131A’s IP protocol filter is a policy-based filter that can allow or filter out IP-based packets with

specified IP protocol and source/destination IP addresses.

The AWK-1131A provides 8 entities for setting IP protocol and source/destination IP addresses in your filtering

policy. Four IP protocols are available: All, ICMP, TCP, and UDP. You must specify either the Source IP or the

Destination IP. By combining IP addresses and netmasks, you can specify a single IP address or a range of IP

addresses to accept or drop. For example, “IP address 192.168.1.1 and netmask 255.255.255.255” refers to

the sole IP address 192.168.1.1. “IP address 192.168.1.1 and netmask 255.255.255.0” refers to the range of

IP addresses from 192.168.1.1 to 192.168.255.

TCP/UDP Port Filters

The AWK-1131A’s TCP/UDP port filter is a policy-based filter that can allow or filter out TCP/UDP-based packets

with a specified source or destination port.

The AWK-1131A provides 8 entities for setting the range of source/destination ports of a specific protocol. In

addition to selecting TCP or UDP protocol, you can set either the source port, destination port, or both. The end

port can be left empty if only a single port is specified. Of course, the end port cannot be larger than the start

port.

The Application name is a text string that describes the corresponding entity with up to 31 characters.

Remember to check the Active check box for each entity to activate the setting.

SNMP Agent

The AWK-1131A supports SNMP V1/V2c/V3. SNMP V1 and SNMP V2c use a community string match for

authentication, which means that SNMP servers access all objects with read-only or read/write permissions

using the community string public/private (default value). SNMP V3, which requires you to select an

authentication level of MD5 or SHA, is the most secure protocol. You can also enable data encryption to

enhance data security.

SNMP security modes and security levels supported by the AWK-1131A are shown in the following table. Select

the security mode and level that will be used to communicate between the SNMP agent and manager.

Link Fault Pass-Through (for Client mode only)

This function means if Ethernet port is link down, wireless connection will be forced to disconnect. Once

Ethernet link is recovered, AWK will try to connect to AP.

If wireless is disconnected, AWK restarts auto-negotiation on Ethernet port but always stays in the link failure

state. Once the wireless connection is recovered, AWK will try to recover the Ethernet link.

System log will indicate the link fault pass through events in addition to the original link up/down events.

Logs and Notifications

Since industrial-grade devices are often located at the endpoints of a system, these devices will not always

know what is happening elsewhere on the network. This means that these devices, including wireless APs or

clients, must provide system maintainers with real-time alarm messages. Even when system administrators

are out of the control room for an extended period, they can still be informed of the status of devices almost

instantaneously when exceptions occur.

In addition to logging these events, the AWK-1131A supports different approaches to warn engineers

automatically, such as SNMP trap and e-mail.

Trap

Traps can be used to signal abnormal conditions (notifications) to a management station. This trap-driven

notification can make your network more efficient.

Because a management station usually takes care of a large number of devices that have a large number of

objects, it will be overloading for the management station to poll or send requests to query every object on

every device. It would be better if the managed device agent could notify the management station by sending

a message known as a trap for the event.

Configuring Wireless Search Utility

The Broadcast Search function is used to locate all AWK-4131A APs that are connected to the same LAN as your

computer. After locating an AWK-4131A, you will be able to change its IP address. Since the Broadcast Search

function searches by TCP packet and not IP address, it doesn’t matter if the AWK-4131A is configured as an AP

or Client. In either case, APs and Clients connected to the LAN will be located, regardless of whether or not they

are part of the same subnet as the host.

1. Start the Wireless Search Utility program. When the Login page appears, select the “Device Search only”

option to search for devices and to view the configuration of each device. Select the “Device management”

Overview

In addition to HTTP access, there are four ways to access AWK-1131A: serial console, Telnet console, SSH

console, and HTTPS console. The serial console connection method, which requires using a short serial cable to

connect the AWK-1131A to a PC’s COM port, can be used if you do not know the AWK-1131A’s IP address. The

other consoles can be used to access the AWK-1131A over an Ethernet LAN, or over the Internet.

RS-232 Console Configuration (115200, None, 8, 1, VT100)

The serial console connection method, which requires using a short serial cable to connect the AWK-1131A to

a PC’s COM port, can be used if you do not know the AWK-1131A’s IP address. It is also convenient to use serial

console configurations when you cannot access the AWK-1131A over Ethernet LAN, such as in the case of LAN

cable disconnections or broadcast storming over the LAN.

though reverse voltage protection is supported.

Before running PComm Terminal Emulator, use an RJ45 to DB9-F (or RJ45 to DB25-F) cable to connect the

AWK-1131A’s RS-232 console port to your PC’s COM port (generally COM1 or COM2, depending on how your

system is set up). After installing PComm Terminal Emulator, take the following steps to access the RS-232

console utility.

the AWK-1131A’s functions over the network from a PC host that is connected to the same LAN as the

AWK-1131A, you need to make sure that the PC host and the AWK-1131A are on the same logical subnet. To

do this, check your PC host’s IP address and subnet mask.

AWK-1131A’s default IP address is 192.168.127.253 and the default subnet mask is

to 192.168.127.xxx and subnet mask to 255.255.255.0.

Follow the steps below to access the console utility via the Telnet command or using an SSH client.

1. Start the windows Run command (Windows start menu, type “run” and press Enter) and use the telnet

command to access the IP address of your AWK-1131A.

Note that you can also run the telnet command from the Command Prompt.

If you are using an SSH client (ex. PuTTY), run the client program and then enter the IP address of your

AWK-1131A, specifying 22 for the SSH connection port.

2. The console login screen is displayed. Refer to RS-232 Console Configuration (previous paragraph) for login

and administration details.

Configuration by Web Browser with HTTPS/SSL

Beacon

A beacon is a packet broadcast by the AP to keep the network synchronized. A beacon includes the wireless LAN

service area, the AP address, the Broadcast destination address, a time stamp, Delivery Traffic Indicator Maps

(DTIM), and the Traffic Indicator Message (TIM). Beacon Interval indicates the frequency interval of AP.

DTIM

Delivery Traffic Indication Map (DTIM) is contained in beacon frames. It is used to indicate that broadcast and

multicast frames buffered by the AP will be delivered shortly. Lower settings result in more efficient networking,

while preventing your PC from dropping into power-saving sleep mode. Higher settings allow your PC to enter

sleep mode, thus saving power.

Fragment

A lower setting means smaller packets, which will create more packets for each transmission. If you have

decreased this value and experience high packet error rates, you can increase it again, but it will likely decrease

overall network performance. Only minor modifications of this value are recommended.

RTS Threshold

RTS Threshold (256-2346) – This setting determines how large a packet can be before the access point

coordinates transmission and reception to ensure efficient communication. This value should remain at its

default setting of 2,346. When you encounter inconsistent data flow, only minor modifications are

recommended.
