First-time Installation and Configuration

Before installing the AWK-1137C, 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-1137C has a default IP address

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

• Step 1: Connect a power source.

The AWK-1137C can be powered by a DC power input.

• Step 2: Connect the AWK-1137C to a notebook or PC.

Since the AWK-1137C supports MDI/MDI-X auto-sensing, you can use either a straight-through cable or

crossover cable to connect the AWK-1137C to a computer. The LED indicator on the AWK-1137C’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-1137C. Since the AWK-1137C’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.

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-1137C

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

AWK-1137C’s operation can be found in Chapter 3.

• Step 6: Test communications.

In the following sections we describe two test methods that can be used to ensure that a network

connection has been established.

Testing the Communication

After setting up the AWK-1137C for the first time, you can perform a simple test to make sure that the AWK can

establish a wireless connection with an AP and is functioning properly.

In this example, an AWK-1137C is configured as a client on the wireless network.

AirWorks AWK-1137C Getting Started

Testing Network Connectivity on AWK-1137C

Connect an AWK-3131A (or another access point) in AP mode to Notebook A. Connect an AWK-1137C to

Notebook B. Configure the AWK-1137C and AWK-1137C with the same SSID and set their IP addresses as

shown in the following figure:

After configuring the WLAN card, establish a wireless connection with the AWK-1137C 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.

Wireless LAN Setup

The AWK-1137C deployed as a Wi-Fi client can be used as an Ethernet-to-wireless and serial-to-wireless

network adapter. AWK-1137C provides point-to-multipoint communication as a client device or

MAC-transparent point-to-point communication as a slave device.

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.

Slave: A transparent point-to-point protocol that allows the devices’ MAC addresses to remain unchanged

when the packets get through the slave radio. If you are looking for a worry-free wireless solution to replace

your wired system, use Master/Slave.

Client-router: A variation of standard client mode. WLAN behavior is identical with client mode, but a router

behavior was added to separate the WLAN and LAN subnets. This allows network planners to allocate private

IP addresses behind the client radio. More information on the Static Route, NAT, and Port Forwarding functions

can be found in the Advanced Setup section.

AeroMag

Moxa's AeroMag tool enables fast, automatic, and error-free configuration of basic Wi-Fi settings based on the

current wireless environment and location of the APs. In an AeroMag topology, AWK-1137C is used as the

AeroMag client with AWK-3131A or AWK-4131A as the AeroMag AP.

Concept

Moxa’s AeroMag technology takes care of the basic Wi-Fi settings for you, saving you considerable effort when

deploying your wireless networks. AeroMag is a useful tool throughout the Wi-Fi network lifecycle. When you

are configuring network devices, AeroMag sets up your Wi-Fi connections correctly in a single step. During the

installation phase, AeroMag streamlines network operation by analyzing the optimal channel for your current

operating environment. From a maintenance perspective, new APs/clients can join the AeroMag topology

without any additional configuration.

Once you have confirmed the number of APs and their location using a site-survey tool and have configured

their device names and IP addresses, connect all the APs to the same network using Layer-2 switches. Next,

activate the AeroMag function on both the APs and clients.

AeroMag decides on the optimum RF type, channels, WPA2 password, and SSID, based on which, AeroMag APs

will generate an optimal configuration and assign it to the AeroMag Clients. AeroMag Clients search for

AeroMag APs to acquire an optimal configuration.

WLAN Security Settings

The AWK-1137C 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-1137C by

selecting Security mode and WPA type:

• 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-1137C can support three EAP methods: EAP-TLS, EAP-TTLS, and EAP-PEAP.

WPA/WPA2-Personal

WPA (Wi-Fi Protected Access) and WPA2 represent 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-1137C 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.

Protected EAP

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.

Because the inner and outer

authentications can use

and PEAP, you can use an

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 when the certificate has expired

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-1137C 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

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

When EAP-TLS is used, a WLAN Certificate will be required at the client end to support WPA/WPA2-Enterprise.

The AWK-1137C can support the PKCS #12, also known as Personal Information Exchange Syntax Standard,

certificate formats that define file formats commonly used to store private keys with accompanying public key

certificates, protected with a password-based symmetric key.

Current status displays information for the current WLAN certificate, which has been imported into the

COM drivers are installed and configured through NPort/OnCell Windows Driver Manager.

Real COM mode allows you to continue using your serial communications software to access devices that are

now attached to your AWK-1137C. On the host, the AWK Real COM driver automatically intercepts data sent to

the COM port, packs it into a TCP/IP packet, and redirects it to the network. At the other end of the connection,

the AWK-1137C accepts the Ethernet frame, unpacks the TCP/IP packet, and sends the serial data to the

appropriate device.

Advanced Setup

Several advanced functions are available to increase the functionality of your AWK-1137C and wireless network

system. A VLAN is a collection of clients and hosts grouped together as if they were connected to the broadcast

domains in a Layer-2 network. The DHCP server helps you deploy wireless clients efficiently. Packet filters

provide security mechanisms, such as firewalls, in different network layers. Moreover, AWK-1137C’s SNMP

support can make network management easier.

Using Virtual LAN

Setting up Virtual LANs (VLANs) on your AWK series increases the efficiency of your network by dividing the

LAN into logical segments, as opposed to physical segments. In general, VLANs are easier to manage.

The Virtual LAN (VLAN) Concept

What is a VLAN?

A virtual LAN, commonly known as a VLAN, is a group of hosts with a common set of requirements that

communicate as if they were attached to the same broadcast domain, regardless of their physical location. A

VLAN has the same attributes as a physical LAN, but it allows for end stations to be grouped together even if

they are not located on the same network switch. Network reconfiguration can be done through software

instead of physically relocating devices.

VLANs now extend as far as the reach of the access point signal. Clients can be segmented into wireless

sub-networks via SSID and VLAN assignment. A Client can access the network by connecting to an AP

configured to support its assigned SSID/VLAN.

Benefits of VLANs

VLANs are used to conveniently, efficiently, and easily manage your network in the following ways:

• Manage adds, moves, and changes from a single point of contact

• Define and monitor groups

• Reduce broadcast and multicast traffic to unnecessary destinations

• Improve network performance and reduce latency

• Increase security

• Secure network restricts members to resources on their own VLAN

• Clients roam without compromising security

VLAN Workgroups and Traffic Management

The AP assigns clients to a VLAN based on a Network Name (SSID). The AP can support up to 9 SSIDs per radio

interface, with a unique VLAN configurable per SSID.

The AP matches packets transmitted or received to a network name with the associated VLAN. Traffic received

by a VLAN is only sent on the wireless interface associated with that same VLAN. This eliminates unnecessary

traffic on the wireless LAN, conserving bandwidth and maximizing throughput.

In addition to enhancing wireless traffic management, the VLAN-capable AP supports easy assignment of

wireless users to workgroups. In a typical scenario, each user VLAN represents a department workgroup; for

example, one VLAN could be used for a marketing department and the other for a human resource department.

In this scenario, the AP would assign every packet it accepted to a VLAN. Each packet would then be identified

as marketing or human resource, depending on which wireless client received it. The AP would insert VLAN

headers or “tags” with identifiers into the packets transmitted on the wired backbone to a network switch.

DHCP Server (For Client-Router 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-1137C 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-1137C

provides a Static DHCP mapping list with up to 16 entities. Be reminded to check the Active check box for

each entity to activate the setting.

You can check the IP assignment status under Status  DHCP Client List.

The AWK-1137C provides 32 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. Remember to check the Active check box for each

NAT Settings/Port Forwarding (For Client-Router Mode Only)

Network Address Translation (NAT)—or to be more specific, one-to-many NAT, NAPT, or PAT—is supported to

facilitate the Client-Router operation mode. This feature translates the out-going communication from multiple

private IPs to a single external IP (WLAN IP) with a randomly assigned port for return traffic.

In order to allow external devices to initiate the communication, Port Forwarding is used to specify a static map

between external ports (WAN Port) and internal IP/port combos (LAN IP/LAN Port)

Enabling NAT and Port Forwarding provides the following benefits:

• Uses the NAT function to hide the Internal IP address of a critical network or device to increase the level of

security of industrial network applications.

• Uses the same private IP address for different, but identical, groups of Ethernet devices. For example,

1-to-many NAT makes it easy to duplicate or extend identical production lines

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-1137C supports different approaches to warn engineers

automatically, such as SNMP trap, e-mail, and relay output. It also supports two digital inputs to integrate

sensors into your system to automate alarms by email and relay output.

Save Configuration

The following figure shows how the AWK-1137C stores the setting changes into volatile and non-volatile

memory. All data stored in volatile memory will disappear when the AWK-1137C is shutdown or rebooted

unless they are y. Because the AWK-1137C starts up and initializes with the settings stored in flash memory,

all new changes must be saved to flash memory before restarting the AWK-1137C.

This also means the new changes will not work unless you run either the Save Configuration function or the

Restart function.

AirWorks AWK-1137C Web Console Configuration

3-74

After you click on Save Configuration in the left menu box, the following screen will appear. Click Save if you

wish to update the configuration settings in the flash memory at this time. Alternatively, you may choose to run

other functions and put off saving the configuration until later. However, the new setting changes will remain

in the non-volatile memory until you save the configurations.

Restart

If you submitted configuration changes, you will find a blinking string in the upper right corner of the screen.

After making all your changes, click the Restart function in the left menu box. One of two different screens will

appear.

If you made changes recently but did not save, you will be given two options. Clicking the Restart button here

will reboot the AWK-1137C directly, and all setting changes will be ignored. Clicking the Save and Restart

button will apply all setting changes and then reboot the AWK-1137C.

Configuring Wireless Search Utility

The Broadcast Search function is used to locate all AWK-1137C APs that are connected to the same LAN as your

computer. After locating an AWK-1137C, 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-1137C 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”

option to assign IPs, upgrade firmware, and locate devices.
