2 2. 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:  First-time Installation and Configuration  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 Getting Started NOTE 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 <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. 3-2

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. 4-2

Wireless Settings The essential settings for wireless networks are presented in this function group. Settings must be properly set before establishing your wireless network. Familiarize yourself with the following terms before starting the configuration process: AP: In a wireless local area network (WLAN), an access point is a station that transmits and receives data. Client: When the AWK-1131A is configured for Client mode, it can be used as an Ethernet-to-wireless (or LAN-to-WLAN) network adaptor. For example, a notebook computer equipped with an Ethernet adaptor but no wireless card can be connected to this device with an Ethernet cable to provide wireless connectivity to another AP. Operation Mode The AWK-1131A supports four main operation modes—AP, Client—each of which plays a distinct role on the wireless network. Wireless Enable Setting Description Factory Default Enable/Disable The RF (Radio Frequency) module can be manually turned on or Enable off. This function is available in AP operation mode only. 3-7

RF type Setting Description Factory Default 2.4 GHz B Only supports the IEEE 802.11b standard B/G/N Mixed G Only supports the IEEE 802.11g standard B/G Mixed Supports IEEE 802.11b/g standards, but 802.11g may operate at a slower speed if when 802.11b clients are on the network G/N Mixed Supports IEEE 802.11g/n standards, but 802.11n may operate at a slower speed if 802.11g clients are on the network B/G/N Mixed Supports IEEE 802.11b/g/n standards, but 802.11g/n may operate at a slower speed if 802.11b clients are on the network N Only (2.4GHz) Only supports the 2.4 GHz IEEE 802.11n standard 5 GHz A Only supports the IEEE 802.11a standard A/N Mixed Supports IEEE 802.11a/n standards, but 802.11n may operate at a slower speed if 802.11a clients are on the network N Only (5GHz) Only supports the 5 GHz IEEE 802.11n standard 3-9

AirWorks AWK-1131A Web Console Configuration NOTE In legacy mode (802.11a/b/g) only antenna port “A” can work for transmitting and receiving. To protect the connectors and the RF module, all radio ports should be terminated by either an antenna or a terminator. The use of the resistive terminator for terminating the unused antenna port is strongly recommended. Channel (for AP mode only) Setting Description Factory Default Available channels vary The AWK-1131A plays the role of wireless AP. 6 (in B/G/N Mixed with RF type mode) Channel Width (for any 802.11N RF type only) Setting Description Factory Default 20 MHz Select your channel width, If you are not sure which option to 20 MHz use, select 20/ 40MHz (Auto) 20/40 MHz Channel bonding If 20/40 MHz only is the Channel Width setting, this channel bonding will auto set the channel based on your channel setting. SSID Setting Description Factory Default Max. of 31 characters The SSID of a client and the SSID of the AP must be identical for MOXA the client and AP to be able to communicate with each other. SSID broadcast (for AP mode only) Setting Description Factory Default Enable/ Disable SSID can be broadcast or not Enable NOTE The AWK-1131A-JP (for Japanese frequency bands) only connects SSID-hidden APs for IEEE 802.11a channels, and IEEE 802.11g/n channels 1 to 11. The AWK-1131A-EU (for European frequency bands) only connects 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. 3-10

AirWorks AWK-1131A Web Console Configuration Security mode Setting Description Factory Default Open No authentication Open WEP Static WEP is used WPA WPA is used WPA2 Fully supports IEEE802.11i with “TKIP/AES + 802.1X” Open For security reasons, you should NOT set security mode to Open System, since 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 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. Authentication type Setting Description Factory Default Open Data encryption is enabled, but without authentication Open Shared Data encryption and authentication are both enabled. Key type Setting Description Factory Default HEX Specifies WEP keys in hex-decimal number form HEX ASCII Specifies WEP keys in ASCII form 3-11

AirWorks AWK-1131A Web Console Configuration Key length Setting Description Factory Default 64 bits Uses 40-bit secret keys with 24-bit initialization vector 64 bits 128 bits Uses 104-bit secret key with 24-bit initialization vector Key index Setting Description Factory Default 1-4 Specifies which WEP key is used Open WEP key 1-4 Setting Description Factory Default ASCII type: A string that can be used as a WEP seed for the RC4 encryption None 64 bits: 5 chars engine. 128 bits: 13chars HEX type: 64 bits: 10 hex chars 128 bits: 26 hex chars 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. WPA type Setting Description Factory Default Personal Provides Pre-Shared Key-enabled WPA and WPA2 Personal Enterprise Provides enterprise-level security for WPA and WPA2 Encryption method Setting Description Factory Default TKIP** Temporal Key Integrity Protocol is enabled AES AES Advance Encryption System is enabled Mixed* Provides TKIP broadcast key and TKIP+AES unicast key for some legacy AP clients. This option is rarely used. ** This option is only available with 802.11a/b/g standard * This option is available for legacy mode in AP only, and does not support AES-enabled clients. 3-12

AirWorks AWK-1131A Web Console Configuration Passphrase Setting Description Factory Default 8 to 63 characters Master key to generate keys for encryption and decryption None Key renewal (for AP mode only) Setting Description Factory Default 60 to 86400 seconds Specifies the time period of group key renewal 3600 (seconds) (1 minute to 1 day) NOTE 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. WPA type Setting Description Factory Default Personal Provides Pre-Shared Key-enabled WPA and WPA2 Personal Enterprise Provides enterprise-level security for WPA and WPA2 Encryption method Setting Description Factory Default TKIP** Temporal Key Integrity Protocol is enabled AES AES Advance Encryption System is enabled Mixed* Provides TKIP broadcast key and TKIP+AES unicast key for some legacy AP clients.

Encryption method Setting Description Factory Default TKIP** Temporal Key Integrity Protocol is enabled TKIP AES Advance Encryption System is enabled **This option is only available with 802.11a/b/g standard. EAP Protocol Setting Description Factory Default TLS Specifies Transport Layer Security protocol TLS TTLS Specifies Tunneled Transport Layer Security PEAP Specifies Protected Extensible Authentication Protocol, or 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 Wireless Settings WLAN Certificate Settings to import your WLAN certificate and enable EAP-TLS on the client end. 3-14

AirWorks AWK-1131A 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. 3-15

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. 3-20

AirWorks AWK-1131A Web Console Configuration 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.

AirWorks AWK-1131A Web Console Configuration 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. Link Fault Pass-Through Setting Description Factory Default Enable Enables Link Fault Pass-Through Disable Disable Disables Link Fault Pass-Through 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. System Log System Log Event Types Detail information for grouped events is shown in the following table. You can check the box for Enable log to enable the grouped events. All default values are enabled (checked). The log for system events can be seen in Status System Log. 3-26

AirWorks AWK-1131A Web Console Configuration 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. Trap Event Types SNMP Trap Receiver Settings SNMP traps are defined in SMIv1 MIBs (SNMPv1) and SMIv2 MIBs (SNMPv2c). The two styles are basically equivalent, and it is possible to convert between the two. You can set the parameters for SNMP trap receivers through the web page. 1st / 2nd Trap version Setting Description Factory Default V1 SNMP trap defined in SNMPv1 V1 V2 SNMP trap defined in SNMPv2 1st / 2nd Trap server IP/name Setting Description Factory Default IP address or host Enter the IP address or name of the trap server used by your None name network. 1st / 2nd Trap community Setting Description Factory Default Max. of 31 characters Use a community string match with a maximum of 31 alert characters for authentication. 3-30

AirWorks AWK-1131A Web Console Configuration 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 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-1131A directly, and all setting changes will be ignored. Clicking the Save and Restart button will apply all setting changes and then reboot the AWK-1131A. 3-37

AirWorks AWK-1131A Web Console Configuration If you run the Restart function without changing any configurations or saving all your changes, you will see just one Restart button on your screen.

5 5. 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. 5-2

AirWorks AWK-1131A Other Console Considerations 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://<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. 5-4

AirWorks AWK-1131A Other Console Considerations 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, then we suggest disabling both Telnet Console and Web Configuration. Please run Maintenance Console Settings to disable them, as shown in the following figure. 5-5

A A. References 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:  Beacon  DTIM  Fragment  RTS Threshold 

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. A-2
