Getting Started
This chapter explains how to install Moxa’s AirWorks AWK-1131A for the first time, and quickly set up your
wireless network and test whether the connection is running well. The Function Map discussed in the third
section provides a convenient means of determining which functions you need to use.
The following topics are covered in this chapter:

 Communication Testing
 Function Map
AirWorks AWK-1131A
Getting Started
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.
NOTE
After you select Maintenance 
Load Factory Default and click the Submit button, the AWK-1131A will be
reset 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:
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.
2-2
AirWorks AWK-1131A
NOTE
Getting Started
After you click Submit to apply changes the web page will refresh (Updated) will appear on the page and a
blinking reminder will be shown on the upper-right corner of the web page:
To activate the changes click Restart and then Save and Restart after you change the settings. About 30
seconds are needed for the AWK-1131A to complete the reboot procedure.
•
Step 5: Select the AWK-1131A operation mode.
By default, the AWK-1131A’s operation mode is set to AP. You can change to Client mode in Wireless
Settings 
Basic Wireless Settings. Detailed information about configuring the AWK-1131A’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.
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 (NOTE: 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 
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
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 
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.

SSID-hidden APs for IEEE 802.11b/g/n channels.
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:
•
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 IEEE802.1X.
The AWK-1131A can support three EAP methods: EAP-TLS, EAP-TTLS, and EAP-PEAP.

For security reasons, you should NOT set security mode to Open System, since authentication and data

WEP (only for legacy mode)
NOTE
Moxa includes WEP security mode only for legacy purposes. WEP is highly insecure and is considered fully
deprecated by the Wi-Fi alliance. We do not recommend the use of WEP security under any circumstances.
According to the IEEE802.11 standard, WEP can be used for authentication and data encryption to maintain
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 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-1131A 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 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
character uses 4 bits, so a 40-bit key has 10 hex characters, and a 128-bit key has 26 characters.

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-1131A also supports AES algorithms in WPA and WPA2
for better compatibility.
Personal versions of WPA/WPA2, also know 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.

The key renewal value dictates how often the wireless AP encryption keys should be changed. The security
level is generally higher if you set the key renewal value to a shorter number, which forces the encryption keys
to be changed more frequently. The default value is 3600 seconds (6 minutes). Longer time periods can be
considered if the line is not very busy.
WPA/WPA2-Enterprise (for AP mode)
By setting WPA type to Enterprise, you can use EAP (Extensible Authentication Protocol), a framework
authentication protocol used by 802.1X to provide network authentication. In these Enterprise-level security
modes, a back-end RADIUS (Remote Authentication Dial-In User Service) server is needed if IEEE 802.1X
functionality is enabled in WPA /WPA2. The IEEE 802.1X protocol also offers the possibility of carrying out an
efficient connection authentication on a large-scale network. It is not necessary to exchange keys or
passphrases.

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 Wireless Settings 
WLAN Certificate Settings to import your WLAN certificate and
enable EAP-TLS on the client end.

Web Console Configuration
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-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
may be useful as inner authentication methods with TTLS and PEAP.
Because the inner and outer authentications can use distinct user names in TTLS and PEAP, you can use an
anonymous user name for the outer authentication, with the true user name only shown through the encrypted
channel. Keep in mind that not all client software supports anonymous alteration. Confirm this with the network
administrator before you enable identity hiding in TTLS and PEAP.

channels may need to be modified when the RF type is changed. (For example, channel 36 is not available in
B, G, N or B/G/N Mix mode.)
WLAN Certification Settings (for EAP-TLS in Client mode only)
When EAP-TLS is used, a WLAN Certificate will be required at the client end to support WPA/WPA2-Enterprise.
The AWK-1131A 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 AWK1131A. Nothing will be shown if a certificate is not available.
Certificate issued to: Shows the certificate user

Advanced Settings
Several advanced functions are available to increase the functionality of your AWK-1131A and wireless network
system. The DHCP server helps you deploy wireless clients efficiently. Packet filters provide security
mechanisms, such as firewalls, in different network layers. Moreover, SNMP support can make network
management easier.
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
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.

Packet Filters
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 Filter
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 Filter
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. Remember to check the Active check box for each entity to

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.
The AWK-1131A’s MIB can be found in the software CD and supports reading the attributes via SNMP. (Only
get method is supported.)
SNMP security modes and security levels supported by the AWK-1131A are shown in the following table. Select

Auto Warning Settings
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, 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.

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 AWK Search Utility
The Broadcast Search function is used to locate all AWK-1131A APs that are connected to the same LAN as your
computer. After locating an AWK-1131A, 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-1131A 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 AWK Search Utility program. When the Login page appears, select the “Search AWK only”
option to search for AWKs and to view each AWK’s configuration. Select the “AWK management” option to
assign IPs, upgrade firmware, and locate devices.

Other Console Considerations
This chapter explains how to access the AWK-1131A for the first time. 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.
The following topics are covered in this chapter:
 RS-232 Console Configuration (115200, None, 8, 1, VT100)
 Configuration by Telnet and SSH Consoles
 Configuration by Web Browser with HTTPS/SSL
 Disabling Telnet and Browser Access
AirWorks AWK-1131A
Other Console Considerations
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.
ATTENTION
Do not use the RS-232 console manager when the AWK-1131A is powered at reversed voltage (ex. -48VDC),
even though reverse voltage protection is supported.
If you need to connect the RS-232 console at reversed voltage, Moxa’s TCC-82 isolator is your best solution.
NOTE
We recommend using Moxa PComm (Lite) Terminal Emulator, which can be downloaded free of charge
from Moxa’s website.
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.
1. From the Windows desktop, open the Start menu and start PComm Terminal Emulator in the PComm
(Lite) group.
2. Select Open under Port Manager to open a new connection.
3. The Communication Parameter page of the Property window opens. Select the appropriate COM port for
Console Connection, 115200 for Baud Rate, 8 for Data Bits, None for Parity, and 1 for Stop Bits. Click on
the Terminal tab, and select VT100 (or ANSI) for Terminal Type. Click on OK to continue.

4. The Console login screen will appear. Log into the RS-232 console with the login name (default: admin)
and password (default: root, if no new password is set).
5. The AWK-1131A’s device information and Main Menu will be displayed. Please follow the description on
screen and select the administration option you wish to perform.
NOTE
To modify the appearance of the PComm Terminal Emulator window, select Edit 
Font and then choose the
desired formatting options.
ATTENTION
If you unplug the RS-232 cable or trigger DTR, a disconnection event will be evoked to enforce logout for
network security. You will need to log in again to resume operation.
Configuration by Telnet and SSH Consoles
You may use Telnet or SSH client to access the AWK-1131A and manage the console over a network. To access
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.
NOTE
The AWK-1131A’s default IP address is 192.168.127.253 and the default subnet mask is 255.255.255.0
(for a Class C network). If you do not set these values properly, please check the network settings of your PC
host and then change the IP address to 192.168.127.xxx and subnet mask to 255.255.255.0.
5-3
AirWorks AWK-1131A
Other Console Considerations
Follow the steps below to access the console utility via Telnet or SSH client.
1. From Windows Desktop, run Start 
Run, and then use Telnet to access the AWK-1131A’s IP address from
the Windows Run window (you may also issue the telnet command from the MS-DOS prompt).
2. When using SSH client (ex. PuTTY), please run the client program (ex. putty.exe) and then input the
AWK-1131A’s IP address, specifying 22 for the SSH connection port.
3. The Console login screen will appear. Please refer to the previous paragraph “RS-232 Console Configuration”
and for login and administration.
Configuration by Web Browser with HTTPS/SSL
To secure your HTTP access, the AWK-1131A supports HTTPS/SSL encryption for all HTTP traffic. Perform the
following steps to access the AWK-1131A’s web browser interface via HTTPS/SSL.
1. Open your web browser and type https:// in the address field. Press Enter to
establish the connection.
2. Warning messages will pop out to warn users that the security certificate was issued by a company they

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.
