WLAN Security Settings
The AWK-1121/1127 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-1121/1127 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-1121/1127 can support three EAP methods: EAP-TLS, EAP-TTLS, and EAP-PEAP.

Factory Default

Open
For security reasons, you should NOT set security mode to Open (or “Open System”), since authentication and data encryption are NOT performed in Open (or “Open System”) mode.
WEP
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-1121/1127 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 104-bit key has 26 hex 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-1121/1127 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 8of 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/WPA2-Enterprise
When used as a client, the AWK-1121/1127 can support three EAP methods (or EAP protocols): EAP-TLS,
EAP-TTLS, and EAP-PEAP, corresponding to WPA/WPA2-Enterprise settings on the AP side.

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.
3-11
AWK-1121/1127 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 Wireless Settings WLAN Certificate Settings to import your WLAN certificate and enable EAP-TLS on the client end.
• 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-1121/1127 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.

SNMP Agent
The AWK-1121/1127 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-1121/1127’s MIB can be found in the software CD and supports reading the attributes via SNMP.
(Only get method is supported.)

Port Forwarding (Client-Router Mode with NAT Enabled)
You can configure the Port Forwarding function on the AWK to hide IP address information for a connection that originates from the WAN.
In the Port Forwarding policy list, specify the port number and the external IP address. For example, if the IP address of a web server on the internal network is 192.168.127.10 with port 80, you can create a port forwarding policy to allow connections to the internal web server from an external IP address 10.10.10.10 on port 8080. The AWK forwards data to IP address 192.168.127.10 on port 80.
The Port Forwarding function enables connection from an external and insecure network (such as the WAN) to an internal network (such as the LAN). However, a user can initiate a connection from an external network to an internal network, but will not able to initiate a connection from the internal network to the external network.

NAT Settings (Client-Router Mode)
NAT (Network Address Translation) is a common security function for changing the IP address during Ethernet packet transmission. If you want to hide an internal IP address on the LAN from an external network (WAN), the NAT function translates the internal IP address with a specific IP address, or an internal IP address range to one external IP address. The benefits of using NAT include:
• Hiding of Internal IP address of a critical network or device to increase the level of security of industrial network applications.
• Using the same private IP address for different, but identical, groups of Ethernet devices. For example,
1-to-1 NAT makes it easy to duplicate or extend identical production lines.

RealCOM Mode
RealCOM mode is designed to work with AWK drivers that are installed on a network host. COM drivers are provided for Windows systems, and TTY drivers are provided for Linux and UNIX systems.
The driver establishes a transparent connection to the attached serial device by mapping a local serial port to the AWK-1127 serial port. RealCOM mode supports up to four simultaneous connections, so multiple hosts can collect data from the attached device at the same time.
Web Console Configuration
ATTENTION
RealCOM drivers are installed and configured through OnCell Windows Driver Manager.
RealCOM mode allows you to continue using your serial communications software to access devices that are now attached to your AWK-1127. On the host, the AWK RealCOM 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-1127 accepts the Ethernet frame, unpacks the TCP/IP packet, and sends the serial data to the appropriate device.
ATTENTION
In RealCOM mode, two hosts can have simultaneous access control over the AWK-1127 serial port.

TCP Alive Check Time
Setting
0 to 99 min.
Description
This field specifies how long the AWK-1127 will wait for a response to “keep alive” packets before closing the TCP connection. The AWK-1127 checks connection status by sending periodic “keep alive” packets.
0: The TCP connection will remain open even if there is no response to the “keep alive” packets.
1 to 99: If the remote host does not respond to the packet within the specified time, the AWK-1127 will force the existing
TCP connection to close.
Factory Default
7 min.
Max Connection
This field specifies the maximum number of connections that will be accepted by the serial port.
Setting
1 or 2
Description Factory Default
1: Only one specific host can access this serial port, and the
RealCOM driver on that host will have full control over the port.
1
2: This serial port will allow the two connections to be opened simultaneously. With simultaneous connections, the RealCOM driver will only provide a pure data tunnel with no control ability. The serial communication will be determined by the
AWK-1127 rather than by your application program.
Application software that is based on the RealCOM driver will receive a driver response of “success” when using any of the
Win32 API functions. The AWK-1127 will send data only to the
RealCOM driver on the host. Data received from hosts will be sent to the attached serial device on a first-in- first-out basis.
ATTENTION
When Max connection is 2, the serial port’s communication settings (i.e., baudrate, parity, data bits, etc.) will be determined by the AWK-1127. Any host that opens the COM port connection must use identical serial communication settings.
Ignore Jammed IP
This field specifies how an unresponsive IP address is handled when there are simultaneous connections to the serial port.
Setting

Force Transmit
This field controls data packing by the amount of time that elapses between bits of data. When using this field, make sure that Inactivity time is disabled or set to a larger value. Otherwise the connection may be closed before the data in the buffer can be transmitted.
Setting
0 to 65535
Description
0: If serial data is received, setting this value to 0 means no data will be buffered and all data will be transmitted immediately as received.
1 to 65535: If serial data is not received for the specified amount of time, the data that is currently in the buffer will be packed for network transmission. The optimal force transmit time depends on your application, but it must be at least larger than one character interval within the specified baudrate. For example, assume that the serial port is set to 1200 bps, 8 data bits, 1 stop bit, and no parity. In this case, the total number of bits needed to send a character is 10 bits, and the time required to transfer one character is 8.3 ms, so the force transmit time to be larger than 8.3 ms.
Factory Default

RFC2217 Mode
RFC2217 mode is similar to RealCOM mode, since it relies on a driver to transparently map a virtual COM port on a host computer to a serial port on the AWK-1127. The RFC2217 standard defines general COM port control options based on the Telnet protocol and supports one connection at a time. Third party drivers supporting
RFC2217 are widely available on the Internet and can be used to implement virtual COM mapping.
When Mode is set to RFC2217 on a serial port’s Operation Modes page, you will be able to configure additional settings such as TCP alive check time, TCP port, and Packet length.

TCP Server Mode
In TCP Server mode, the AWK-1127 serial port is assigned an IP:port address that is unique on your TCP/IP network. It waits for the host computer to establish a connection to the attached serial device. This operation mode also supports up to four simultaneous connections, so multiple hosts can collect data from the attached device at the same time.
Data transmission proceeds as follows:
1. A host requests a connection to the
AWK-1127 serial port.
2. Once the connection is established, data can be transmitted in both directions—from the host to the device, and from the device to the host.

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-1121/1127 supports different approaches to warn engineers automatically, such as SNMP trap or e-mail.

Trap
Traps can be used to signal abnormal conditions (notifications) to a management station. This trap-driven notification can make your network more efficient.
Because a management station usually takes care of a large number of devices that have a large number of objects, it will be overloading for the management station to poll or send requests to query every object on every device. It would be better if the managed device agent could notify the management station by sending a message known as a trap for the event.

7. Click on the created COM port to select it. Then right click to select Basic Setting tab. On the Basic Setting tab, use the COM Number drop-down list to select a COM number to be assigned to the AWK-1127’s serial port that is being configured. Note that ports that are “in use” will be labeled accordingly.
8. Click the Advanced Setting tab to modify Tx Mode, FIFO, Fast Flush, and other parameters.
4-12
AWK-1121/1127 Software Installation and Configuration
Tx Mode
Hi-Performance is the default for Tx mode. After the driver sends data to the AWK-1127 , the driver immediately issues a “Tx Empty” response to the program. Under Classical mode, the driver will not send the “Tx Empty” response until after confirmation is received from the AWK-1127 ’s serial port. This causes lower throughput. Classical mode is recommended if you want to ensure that all data is sent out before further processing.
FIFO
If FIFO is Disabled, the AWK-1127 will transmit one byte at a time when the Tx FIFO becomes empty, and an Rx interrupt will be generated for each incoming byte. This will result in a faster response and lower throughput.
Network Timeout
You can use this option to prevent blocking if the target OnCell is unavailable.
Auto Network Re-Connection
With this option enabled, the driver will repeatedly attempt to re-establish the TCP connection if the
AWK-1127 does not respond to background “check alive” packets.
Return error if network is unavailable
If this option is disabled, the driver will not return any error even when a connection cannot be established to the AWK-1127. With this option enabled, calling the Win32 Comm function will result in the error return code “STATUS_NETWORK_UNREACHABLE” when a connection cannot be established to the AWK-1127.
This usually means that your host’s network connection is down, perhaps due to a cable being disconnected.
However, if you can reach other network devices, it may be that the AWK-1127 is not powered on or is disconnected. Note that Auto Network Re-Connection must be enabled in order to use this function.
Fast Flush (only flushes the local buffer)
For some applications, the user’s program will use the Win32 “PurgeComm()” function before it reads or writes data. After a program uses this PurgeComm() function, the OnCell driver continues to query the
OnCell’s firmware several times to make sure no data is queued in the OnCell firmware buffer, rather than just flushing the local buffer. This design is used to satisfy some special considerations. However, it may take more time (about several hundred milliseconds) than a native COM1 due to the additional time spent communicating across the Ethernet. This is why PurgeComm() works significantly faster with native COM ports on the PC than with mapped COM ports on the AWK-1127 . In order to accommodate other applications that require a faster response time, the new OnCell driver implements a new Fast Flush option.
By default, this function is enabled.
If you have disabled Fast Flush and find that COM ports mapped to the AWK-1127 perform markedly slower than when using a native COM port, try to verify if “PurgeComm()” functions are used in your application.
If so, try enabling the Fast Flush function and see if there is a significant improvement in performance.
Auto IP Report: The functions applies to OnCell Series only and does not apply to the AWK-1127.
9. The Serial Parameters tab in the following figure show the default settings when the AWK-1127 is powered on. However, the program can redefine the serial parameters to different values after the program opens the port with Win32 API.

AWK-1121/1127 Software Installation and Configuration
10. Click the Security tab to configure security settings. Select the Enable Data Encryption option to enable data to be encrypted when transmitted over the COM ports. After selecting the encryption option, select the
Keep connection option to start encrypting COM port communications immediately without restarting the
COM ports. (If your application opens and closes COM ports frequently and the AWK-1127 is only for one host, you can enable this option to speed up the opening/closing time. However, this will result in your host tying up the COM port so that other hosts cannot use it.).
4-14
AWK-1121/1127 Software Installation and Configuration
11. To save the configuration to a text file, select Export from the COM Mapping menu. You will then be able to import this configuration file to another host and use the same COM Mapping settings in the other host.
Moxa OnCell Linux Real TTY Driver
The AWK-1127 uses the same Real TTY serial driver as Moxa’s OnCell cellular gateways. The below section describes how to use the OnCell Linux Real TTY Driver to map a virtual tty port for the AWK-1127.
Basic Procedure
To map an AWK-1127 serial port to a Linux host’s tty port, follow these instructions:
1. Set up the AWK-1127. After verifying that the IP configuration works and you can access the AWK-1127 (by using ping, telnet, etc.), configure the desired serial port on the AWK-1127 to RealCOM mode.
2. Install the Linux Real TTY driver files on the host.
3. Map the AWK-1127 serial port to the host’s tty port.
Hardware Setup
Before proceeding with the software installation, make sure you have completed the hardware installation.
Note that the default IP address for the LAN interface of AWK-1127 is 192.168.127.253.
NOTE
After installing the hardware, you must configure the operation mode of the serial port on your AWK-1127 to
RealCOM mode.
Installing Linux Real TTY Driver Files
1. Obtain the driver file from the included CD-ROM or the Moxa website, at http://www.moxa.com.
2. Log in to the console as a super user (root).
3. Execute cd / to go to the root directory.
4. Copy the driver file moxa_oncell_realtty.tgz to the / directory.
5. Execute tar xvfz moxa_oncell_realtty.tgz to extract all files into the system.
6. Execute /tmp/oncell_realtty/mxinst.
For RedHat AS/ES/WS and Fedora Core1, append an extra argument as follows:
# /tmp/oncell_realtty/mxinst SP1
The shell script will install the driver files automatically.
4-15
AWK-1121/1127 Software Installation and Configuration
7. After installing the driver, you will be able to see several files in the /usr/lib/oncell_realtty/driver folder:
> mxaddsvr (Add Server, mapping tty port)
> mxdelsvr (Delete Server, un-mapping tty port)
> mxloadsvr (Reload Server)
> mxmknod (Create device node/tty port)
> mxrmnod (Remove device node/tty port)
> mxuninst (Remove tty port and driver files)
At this point, you will be ready to map the AWK-1127 serial port to the system tty port.
Mapping TTY Ports
Make sure that you set the operation mode of the desired AWK-1127 serial port to RealCOM mode. After logging in as a super user, enter the directory /usr/lib/oncell_realtty/driver and then execute mxaddsvr to map the target OnCell serial port to the host tty ports. The syntax of mxaddsvr is as follows:
mxaddsvr [OnCell IP Address] [Total Ports] ([Data port] [Cmd port])
The mxaddsvr command performs the following actions:
1. Modifies oncellreald.cf.
2. Creates tty ports in directory /dev with major & minor number configured in oncellreald.cf.
3. Restarts the driver.
Mapping tty ports automatically
To map tty ports automatically, you may execute mxaddsvr with just the IP address and number of ports, as in the following example:
# cd /usr/lib/oncell_realtty/driver
# ./mxaddsvr 192.168.3.4 1
In this example, one tty port will be added, with IP 192.168.3.4, with data port 950 and command port 966.
Mapping tty ports manually
To map tty ports manually, you may execute mxaddsvr and manually specify the data and command ports, as in the following example:
# cd /usr/lib/oncell_realtty/driver
# ./mxaddsvr 192.168.3.4 1 4001 966
In this example, one tty port will be added, with IP 192.168.3.4, with data port 4001 and command port 966.

AWK-1121/1127 Software Installation and Configuration
Removing Mapped TTY Ports
After logging in as root, enter the directory /usr/lib/oncell_realtty/driver and then execute mxdelsvr to delete a server. The syntax of mxdelsvr is:
mxdelsvr [IP Address]
Example:
# cd /usr/lib/oncell_realtty/driver
# ./mxdelsvr 192.168.3.4
The following actions are performed when executing mxdelsvr:
1. Modify oncellreald.cf.
2. Remove the relevant tty ports in directory /dev.
3. Restart the driver.
If the IP address is not provided in the command line, the program will list the installed servers and total ports on the screen. You will need to choose a server from the list for deletion.
Removing Linux Driver Files
A utility is included that will remove all driver files, mapped tty ports, and unload the driver. To do this, you only need to enter the directory /usr/lib/oncell_realtty/driver, then execute mxuninst to uninstall the driver.
This program will perform the following actions:
1. Unload the driver.
2. Delete all files and directories in /usr/lib/moxa_oncell
3. Delete directory /usr/lib/moxa_oncell
4. Modify the system initializing script file.

Configuring the UNIX Driver
Software Installation and Configuration
Modify the configuration
The configuration used by the oncellttyd program is defined in the text file oncellttyd.cf, which is in the same directory that contains the program oncellttyd. You may use vi, or any text editor to modify the file, as follows:
ttyp1 192.168.1.1 950
For more configuration information, view the file oncellttyd.cf, which contains detailed descriptions of the various configuration parameters.
NOTE
The “Device Name” depends on the OS. See the Device Naming Rule section in README.TXT for more information.
To start the oncellttyd daemon after system bootup, add an entry into /etc/inittab, with the tty name you configured in oncellttyd.cf, as in the following example:
ts:2:respawn:/usr/etc/oncell_fixedtty/oncellttyd –t 1
Device naming rule
For UnixWare 7, UnixWare 2.1.x, and SVR4.2, use:
pts/[n]
For all other UNIX operating systems, use:
ttyp[n]
Starting moxattyd
Execute the command init q or reboot your UNIX operating system.
Adding an additional server
1. Modify the text file oncellttyd.cf to add an additional server. User may use vi or any text editor to modify the file. For more configuration information, look at the file oncellttyd.cf, which contains detailed descriptions of the various configuration parameters.
2. Find the process ID (PID) of the program oncellttyd.
# ps -ef | grep oncellttyd
3. Update configuration of oncellttyd program.
# kill -USR1 [PID]
(e.g., if oncellttyd PID = 404, kill -USR1 404)
This completes the process of adding an additional server.

Other Console Considerations
This chapter explains how to access the AWK-1121/1127 for the first time. In addition to HTTP access, there are four ways to access AWK-1121/1127: 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-1121/1127 to a PC’s COM port, can be used if you do not know the AWK-1121/1127’s IP address. The other consoles can be used to access the AWK-1121/1127 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

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-1121/1127 to a PC’s COM port, can be used if you do not know the AWK-1121/1127’s IP address. It is also convenient to use serial console configurations when you cannot access the AWK-1121/1127 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-1121/1127 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-1121/1127’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

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.
