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:
First-time Installation and Configuration
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: moxa
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.

AirWorks AWK-1131A Getting Started
NOTE After you click Submit to apply changes the web page is refreshed (indicated by an “(Updated)” status appearing next to the title) and a blinking reminder to restart the device of the new settings to take effect, 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 LAN
Setup Operation Mode. 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 <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.
2-3
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 <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 supports a “Sniffer” mode to co-work with Wireshark packet sniffer software.
NOTE
Although it is more convenient to use dynamic bridging, there is a limitation—the Client can only transmit
IP-based packets between its wireless interface (WLAN) and Ethernet interface (LAN); other types of traffic
(such as IPX and AppleTalk) are not forwarded.

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 IEEE 802.1X.
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 because authentication and data encryption are not performed in Open System mode.
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 IEEE 802.11 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 in
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 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.

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/Master 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.
3-15
AirWorks AWK-1131A Web Console Configuration
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.
3-16
AirWorks AWK-1131A
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.

3-19
AirWorks AWK-1131A Web Console Configuration
When Turbo Roaming is enabled, the following parameters will be shown:
• Roaming threshold: Determines when to start looking for new AP candidates. If the current connection quality (SNR or Signal Strength) is lower than the specified threshold, the AWK will start background scanning and look for next-hop candidates.
NOTE
While the AWK is background scanning, the wireless performance will be reduced by 1/3 of its normal performance.
• Roaming difference: Determines if roaming should be executed. After background scan has been triggered, the roaming will only occur if the AP candidate(s) provide a better (Roaming difference) connection quality than the current connection. If multiple access points fulfill the criteria, the AWK will pick the best one to roam to.
• Scan channels: Pre-define communication and roaming channels.
• AP alive check: Allows the turbo roaming function to recover the network connection faster when an AP has a sudden disconnection (such as losing power).
NOTE
Enabling this feature causes the AWK-1131A to send out alive check packets every 10 ms when there is no traffic; the high transmission frequency of small alive check packets could potentially affect your other wireless communications that use the same channel, so only enable this feature when you have full control of the designated radio channel.
• AP candidate threshold: After the “AP alive check” declares the current access point is no long available, the surrounding access points must have good enough connection qualities (SNR/Signal Strength) in order to be the qualified as AP candidates for association.
MAC clone (for Client mode only)
Setting

Advanced Setup
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. And, 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 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.

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.
System Logs
System Log Event Types
All the event group types are shown on this page. Select the event types (groups) that you want to enable by checking the Enable logging box next to the event types. By default, all event types are enabled (checked).

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.

Save Configuration
The following figure shows how the AWK-1131A stores the setting changes into volatile and non-volatile memory. All data stored in volatile memory will disappear when the AWK-1131A is shutdown or rebooted unless they are y. Because the AWK-1131A starts up and initializes with the settings stored in flash memory, all new changes must be saved to flash memory before restarting the AWK-1131A.
This also means the new changes will not work unless you run either the Save Configuration function or the
Restart function.
After you click on Save Configuration in the left menu box, the following screen is displayed. Click Save if you want to update the configuration settings in the flash memory at this time. Alternatively, you can 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.

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

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.
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.

Bits. Click on the Terminal tab, and select VT100 (or ANSI) for Terminal Type. Click on OK to continue.
4. The console login screen is displayed. Log into the RS-232 console with the login name (default: admin) and password (default: moxa, if no new password is set).
5. The AWK-1131A’s device information and Main Menu will be displayed. Follow the instructions on the screen to select the administration task that you want 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.

AirWorks AWK-1131A Additional Consoles
Configuration by Telnet and SSH Consoles
You can 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.
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: You can also issue the telnet command from the MS-DOS 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
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://<AWK-1131A’s IP address> 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 have not chosen to trust.
3. Select Yes to accept the certificate issued by Moxa IW and then enter the AWK-1131A’s web browser interface secured via HTTPS/SSL. (You can see the protocol in URL is https.) Then you can use the menu tree on the left side of the window to open the function pages to access each of AWK-1131A’s functions.
Disabling Telnet and Browser Access
If you are connecting the AWK-1131A to a public network but do not intend to use its management functions over the network, we suggest disabling the Telnet console and the Web consoles at Maintenance
Console Settings.

This chapter provides more detailed information about wireless-related technologies. The information in this chapter can help you administer your AWK-1131As and plan your industrial wireless network better.
The following topics are covered in this appendix:
AirWorks AWK-1131A References
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.
