NPort W2150A/W2250A Series Getting Started 2-5 Placement Options The NPort can be placed on a desktop or other horizontal surface. You can also install the NPort on a DIN-rail or on the wall. Wall Mounting DIN-Rail Mounting Connecting the Hardware ATTENTION Before connecting the hardware, follow these important wiring safety precautions: Disconnect power source Do not install or wire this unit or any attached devices with the power connected. Disconnect the power before installation by removing the power cord before installing and/or wiring your unit. Follow maximum current ratings Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes dictating the maximum current allowable for each wire size. If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your equipment. Use caution - unit may get hot The unit will generate heat during operation, and the casing may feel hot to the touch. Take care when handling unit. Be sure to leave adequate space for ventilation. The following guidelines will help ensure trouble-free signal communication with the NPort. • Use separate paths to route wiring for power and devices to avoid interference. Do not run signal or communication wiring and power wiring in the same wire conduit. The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together. • If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the intersection point. • Keep input wiring and output wiring separate. • Label all wiring to each device in the system for easier testing and troubleshooting

NPort W2150A/W2250A Series Getting Started 2-6 Connecting to the Network Use the supplied Ethernet cable to connect the NPort to your Ethernet network. If the cable is properly connected, the NPort will indicate a valid connection to the Ethernet as follows: • A green Ethernet LED indicates a valid connection to a 100 Mbps Ethernet network. • An orange Ethernet LED indicates a valid connection to a 10 Mbps Ethernet network. • A flashing Ethernet LED indicates that Ethernet packets are being transmitted or received. Connecting the Power Connect the VDC power line (12 to 48 V) to the NPort’s power jack or terminal block. If power is properly connected, the “Ready” LED will initially glow red. When the system is ready, the “Ready” LED will turn green. Connecting to a Serial Device Use a serial cable to connect your serial device to a serial port on the NPort.

3 3. Initial IP Configuration The following topics are covered in this chapter:  Overview  Factory Default IP Settings  Using ARP to Assign IP Address  Using the Telnet Console to Assign IP Address  Using the Serial Console to Assign IP Address

NPort W2150A/W2250A Series Initial IP Configuration 3-2 Overview This chapter presents several ways to assign the NPort’s IP address for the first time. Please refer to Chapter 2 for instructions on connecting to the network. The web console is the recommended method for configuring the NPort. Please refer to Chapter 5 and 6 for details on using the web console for configuration. ATTENTION The LAN and WLAN interfaces cannot be used at the same time. If the Ethernet link is active, then WLAN connections will be disabled. If the WLAN connection is active, then the Ethernet link will be disabled. ATTENTION Make sure that the Ethernet cable is connected before powering up the NPort. Factory Default IP Settings Network Interface IP Configuration IP Address Netmask LAN Static 192.168.126.254 255.255.255.0 WLAN Static 192.168.127.254 255.255.255.0 If your NPort is configured to obtain its IP settings from a DHCP or BOOTP server but is unable to get a response, it will use the factory default IP address and netmask. ATTENTION If you forget the IP address of your NPort, you can look it up using the NPort Search Utility. After NPort Search Utility has found all NPorts on the network, each unit will be listed with its IP address. Please refer to Chapter 11 for additional information on using NPort Search Utility. Using ARP to Assign IP Address The ARP (Address Resolution Protocol) command can be used to assign an IP address to the NPort. The ARP command tells your computer to associate the NPort’s MAC address with the specified IP address. You must then use Telnet to access the NPort, at which point the device server’s IP address will be reconfigured. This method only works when the NPort is configured with default IP settings. 1. Select a valid IP address for your NPort. Consult with your network administrator if necessary. 2. Obtain the NPort’s MAC address from the label on its bottom panel. 3. From the DOS prompt, execute the arp -s command with the desired IP address and the NPort’s MAC address, as in the following example: arp -s 192.168.200.100 00-90-E8-xx-xx-xx In this example 192.168.200.100 is the new IP address that will be assigned to the NPort, and 00-90-E8-xx-xx-xx is the NPort’s MAC address. 4. From the DOS prompt, execute a special Telnet command using port 6000, as in the following example: telnet 192.168.200.100 6000 In this example, 192.168.200.100 is the new IP address that will be assigned to the NPort.

NPort W2150A/W2250A Series Initial IP Configuration 3-3 5. You will see a message indicating that the connection failed. The NPort will automatically reboot with the new IP address. You can verify that the configuration was successful by connecting to the new IP address with Telnet, ping, the web console, or NPort Search Utility. Using the Telnet Console to Assign IP Address 1. Select Run… from the Windows Start menu. 2. Enter telnet 192.168.126.254 (the NPort’s default IP address) and click [OK]. 3. Enter your login account and password, then press ENTER. 4. You will login to the Overview page.

For IP configuration and LAN speed, press ENTER to open a submenu and select between the available options. 8. Press ESC to return to the menu. When prompted, press Y to save the configuration changes. The NPort will reboot with the new IP settings. You can telnet to the new IP to login again.

NPort W2150A/W2250A Series Initial IP Configuration 3-6 Using the Serial Console to Assign IP Address Before using the NPort’s serial console, turn off the power and use a serial cable to connect the NPort console port to your computer’s serial port. Port 1 on the NPort serves as the console port. Use Port 1 connecting to the console port with a serial-based terminal or terminal emulator program, such as Windows HyperTerminal. You may also download PComm Lite at www.moxa.com. The terminal type should be set as ANSI or VT100, and the serial communication parameters should be set as 19200, 8, N, 1 (19200 for baud rate, 8 for data bits, None for parity, and 1 for stop bits). As soon as the connection is open, you will be presented with a text menu displaying the NPort W2150A/W2250A Series general settings. Please refer to Chapter 4 for a description of the available settings. The following instructions, we recommend using PComm Terminal Emulator, which can be downloaded free of charge from www.moxa.com, to carry out the configuration procedure. 1. Connect your PC’s serial port to the NPort’s console port. 2. Open your terminal emulator program, such as Windows HyperTerminal. We recommend using PComm Terminal Emulator, which can be downloaded for free at www.moxa.com. 3. In your terminal emulator program, configure the communication parameters for the serial port on the PC. The parameters should be set to 19200 for baud rate, 8 for data bits, None for parity, and 1 for stop bits. 4. In your terminal emulator program, set the terminal type to ANSI or VT100. If you select Dumb Terminal as the terminal type, some of the console functions—especially the “Monitor” function—may not work properly.

Please refer to the Telnet console section for instructions on how to navigate the console and configure the IP settings.

4 4. Introduction to Operation Modes The following topics are covered in this chapter:  Overview  RealCOM Mode  RFC2217 Mode  TCP Server Mode  TCP Client Mode  UDP Mode  Pair Master and Pair Connection Modes  Ethernet Modem Mode

NPort W2150A/W2250A Series Introduction to Operation Modes 4-2 Overview This chapter introduces the different serial port operation modes that are available on the NPort W2150A/W2250A Series. Each serial port on the NPort is configured independently of the other ports, with its own serial communication parameters and operation mode. The serial port’s operation mode determines how it interacts with the network, and different modes are available to encompass a wide variety of applications and devices. RealCOM and RFC2217 modes allow serial-based software to access the NPort serial port as if it were a local serial port on a PC. These modes are appropriate when your application relies on Windows or Linux software that was originally designed for locally attached COM or TTY devices. With these modes, you can access your devices from the network using your existing COM/TTY-based software, without investing in additional software. Three different socket modes are available for user-developed socket programs: TCP Server, TCP Client, and UDP Server/Client. For TCP applications, the appropriate mode depends on whether the connection will be hosted or initiated from the NPort serial port or from the network. The main difference between the TCP and UDP protocols is that TCP guarantees delivery of data by requiring the recipient to send an acknowledgement to the sender. UDP does not require this type of verification, making it possible to offer speedier delivery. UDP also allows multicasting of data to groups of IP addresses and would be suitable for streaming media or non-critical messaging applications such as LED message boards. Pair Connection Slave and Master modes are designed for serial-to-serial communication over Ethernet, in order to overcome traditional limitations with serial transmission distance. In Ethernet Modem mode, the NPort acts as an Ethernet modem, providing a network connection to a host through the serial port. RealCOM Mode RealCOM mode is designed to work with NPort 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 NPort serial port. RealCOM mode supports up to four simultaneous connections, so multiple hosts can collect data from the attached device at the same time. ATTENTION RealCOM drivers are installed and configured through NPort Windows Driver Manager. RealCOM mode allows you to continue using your serial communications software to access devices that are now attached to your NPort device server. On the host, the NPort 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 NPort device server accepts the Ethernet frame, unpacks the TCP/IP packet, and sends the serial data to the appropriate device.

NPort W2150A/W2250A Series Introduction to Operation Modes 4-3 ATTENTION In RealCOM mode, several hosts can have simultaneous access control over the NPort serial port. If necessary, you can limit access by using the NPort’s Accessible IP settings. Please refer to Chapter 8 for additional information on Accessible IP settings. RFC2217 Mode RFC-2217 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 NPort. 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 RFC-2217 are widely available on the Internet and can be used to implement virtual COM mapping. TCP Server Mode In TCP Server mode, the NPort 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 eight simultaneous connections, so multiple hosts can collect data from the attached device at the same time. Data transmission proceeds as follows: A host requests a connection to the NPort serial port. 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. TCP Client Mode In TCP Client mode, the NPort actively establishes a TCP connection to a specific network host when data is received from the attached serial device. After the data has been transferred, the NPort can automatically disconnect from the host computer through the Inactivity time settings. Please refer to Chapter 7 for details on these parameters. Data transmission proceeds as follows: The NPort requests a connection from the host. The connection is established and data can be transmitted in both directions between the host and device.

NPort W2150A/W2250A Series Introduction to Operation Modes 4-4 UDP Mode UDP is similar to TCP but is faster and more efficient. Data can be broadcast to or received from multiple network hosts. However, UDP does not support verification of data and would not be suitable for applications where data integrity is critical. It is ideal for message display applications. Pair Connection Modes Pair Connection Master and Slave modes connect two NPort device servers over a network for serial-to-serial communication. A device attached to one NPort can then communicate transparently to a device attached to the other NPort, as if the two devices were connected by a serial cable. Both data and modem control signals are exchanged, except for DCD signals. This can be used to overcome traditional limitations with serial communication distance and introduces many new possibilities for serial-based device control. Ethernet Modem Mode Ethernet Modem mode is designed for use with legacy operating systems, such as MS-DOS, that do not support TCP/IP Ethernet. By connecting the properly configured NPort serial port to the MS-DOS computer’s serial port, it is possible to use legacy software to transmit data over the Ethernet when the software was originally designed to transmit data over a modem.

NPort W2150A/W2250A Series Web Console: Basic Settings 5-2 Overview This chapter introduces the NPort web console and explains how to configure the basic settings. The NPort can be configured from anywhere on the network through its web console. Simply point the browser to the device server’s IP address to open the web console. Network settings, operation mode, and other items can all be configured through the browser. Web Browser Settings In order to use the web console, you will need to have cookies enabled for your browser. Please note that the web console uses cookies only for password transmission. For Internet Explorer, cookies can be enabled by right-clicking the Internet Explorer icon on your desktop and selecting Properties from the context menu. On the Security tab, click “Custom Level…” and enable these two items: Allow cookies that are stored on your computer. Allow per-session cookies (not stored). ATTENTION If you are not using Internet Explorer, cookies are usually enabled through a web browser setting such as “allow cookies that are stored on your computer” or “allow per-session cookies.” Navigating the Web Console To open the web console, enter your device server’s IP address in the website address line. If you are configuring the NPort for the first time over an Ethernet cable, you will use the default IP address, 192.168.126.254. There are two account types: admin and user. If you enter the system with admin account, you will have the right to read and write. If you enter the system with user account, you will only have the right to read. If prompted, enter the console password. You will only be prompted for a password if you have enabled password protection on the device server. The password will be transmitted with MD5 encryption over the Ethernet.

NPort W2150A/W2250A Series Web Console: Basic Settings 5-3 ATTENTION If you have forgotten the password, you can use the reset button to load factory defaults, but this will erase all previous configuration information. The web console will appear as shown below. Settings are presented on pages that are organized by folder. Select the desired folder in the left navigation panel to open that page. The page will be displayed in the main window on the right. Certain folders can be expanded by clicking the adjacent “–” symbol. For example, if you click Basic Settings in the navigation panel, the main window will show a page of basic settings that you can configure. After you have made changes on a page, you must click [Submit] in the main window before jumping to another page. Your changes will be lost if you do not click [Submit].

Time Server Default Options IP address or domain name (e.g., “192.168.1.1” or “time.nist.gov”) Description This optional field specifies your time server’s IP address or domain name, if a time server is used in your network. The NPort supports SNTP (RFC-1769) for automatic time calibration. The device server will request time information from the specified time server every 10 minutes.

6 6. Web Console: Network Settings The following topics are covered in this chapter:  Overview  Network Settings  General Settings  Ethernet Settings  WLAN Settings  Advanced Settings

NPort W2150A/W2250A Series Web Console: Network Settings 6-2 Overview This chapter explains how to configure all settings located under the Network Settings folder in the NPort web console. Network Settings General Settings On the General Settings page in the Network Settings folder, you can modify DNS server 1 and 2. DNS Server 1 and 2 Default Options IP address (e.g., “192.168.1.1”) Description This field is for the DNS server’s IP address, if applicable. With the DNS server configured, the NPort device server can use domain names instead of IP addresses to access hosts. Domain Name System (DNS) is how Internet domain names are identified and translated into IP addresses. A domain name is an alphanumeric name, such as www.moxa.com, that it is usually easier to remember than the numeric IP address. A DNS server is a host that translates a text-based domain name into an IP address in order to establish a TCP/IP connection. When the user wants to visit a particular website, the user’s computer sends the domain name (e.g., www.moxa.com) to a DNS server to request that website’s numeric IP address. When the IP address is received from the DNS server, the user’s computer uses that information to connect to the website’s web server. The NPort will play the role of a DNS client, actively querying the DNS server for the IP address associated with a particular domain name.

NPort W2150A/W2250A Series Web Console: Network Settings 6-3 Ethernet Settings On the Ethernet Settings page in the Network Settings folder, you can modify IP configuration, IP address, Netmask, and Gateway. You must assign a valid IP address to the NPort before it will work in your network environment. Your network system administrator should provide you with an IP address and related settings for your network. The IP address must be unique within the network; otherwise the NPort will not have a valid connection to the network. First-time users should refer to Chapter 3, “Initial IP Address Configuration,” for more information. IP Configuration Default Static Options Static, DHCP, DHCP/BOOTP, BOOTP Description This field determines how the NPort’s IP address will be assigned. Static: IP address, netmask, and gateway are user-defined. DHCP: IP address, netmask, gateway, DNS, and time server are assigned by DHCP server. DHCP/BOOTP: IP address, netmask, gateway, DNS, and time server are assigned by DHCP server. IP address is assigned by BOOTP server if DHCP server does not respond. BOOTP: IP address is assigned by BOOTP server. IP Address Default 192.168.126.254 Options IP address (e.g., “192.168.1.1”) Description This field is for the IP address that will be assigned to your NPort device server. An IP address is a number assigned to a network device (such as a computer) as a permanent address on the network. Computers use the IP address to identify and talk to each other over the network. Choose a proper IP address that is unique and valid in your network environment. If your device server will be assigned a dynamic IP address, set the “IP configuration” parameter appropriately.

NPort W2150A/W2250A Series Web Console: Network Settings 6-4 Netmask Default 255.255.255.0 Options Netmask setting (e.g., “255.255.0.0”) Description This field is for the subnet mask. A subnet mask represents all of the network hosts at one geographic location, in one building, or on the same local area network. When a packet is sent out over the network, the NPort device server will use the subnet mask to check whether the desired TCP/IP host specified in the packet is on the local network segment. If the address is on the same network segment as the device server, a connection is established directly from the device server. Otherwise, the connection is established through the gateway as specified in the “Gateway” parameter. Gateway Default Options IP address (e.g., “192.168.1.1”) Description This field is for the IP address of the gateway, if applicable. A gateway is a network computer that acts as an entrance to another network. Usually, the computers that control traffic within the network or at the local Internet service provider are gateway nodes. The NPort device server needs to know the IP address of the default gateway computer in order to communicate with the hosts outside the local network environment. Consult your network administrator if you do not know how to set this parameter. ATTENTION In dynamic IP environments, the NPort will send 3 requests every 30 seconds to the DHCP or BOOTP server until the network settings have successfully been assigned. The first request will time out after one second; the second request will time out after three seconds, and the third request will timeout after five second. If the DHCP or BOOTP server is unavailable, the NPort will use the factory default network settings. WLAN Settings WLAN

NPort W2150A/W2250A Series Web Console: Network Settings 6-5 The WLAN page is located under WLAN Settings in the Network Settings folder. You can modify IP configuration, IP address, Netmask, and Gateway for your WLAN. The NPort W2150A/W2250A Series supports IEEE 802.11a/b/g wireless network interfaces. The supported IP configurations are static and dynamic (BOOTP, DHCP, or BOOTP+DHCP). Users can set up the IP configuration with the serial console, or the Web/Telnet consoles through the NPort’s Ethernet interface. For detailed information about configuring IP configuration, IP address, Netmask, and Gateway, see the previous section, Ethernet Configuration. IP Configuration Default Static Options Static, DHCP, DHCP/BOOTP, BOOTP Description This field determines how the NPort’s IP address will be assigned. Static: IP address, netmask, and gateway are user-defined. DHCP: IP address, netmask, gateway, DNS, and time server are assigned by DHCP server. DHCP/BOOTP: IP address, netmask, gateway, DNS, and time server are assigned by DHCP server. IP address is assigned by BOOTP server if DHCP server does not respond. BOOTP: IP address is assigned by BOOTP server. IP Address Default 192.168.127.254 Options IP address (e.g., “192.168.1.1”) Description This field is for the IP address that will be assigned to your NPort device server. An IP address is a number assigned to a network device (such as a computer) as a permanent address on the network. Computers use the IP address to identify and talk to each other over the network. Choose a proper IP address that is unique and valid in your WLAN environment. If your device server will be assigned a dynamic IP address, set the “IP configuration” parameter appropriately. Netmask Default 255.255.255.0 Options Netmask setting (e.g., “255.255.0.0”) Description This field is for the subnet mask. A subnet mask represents all of the network hosts at one geographic location, in one building, or on the same local area network. When a packet is sent out over the network, the NPort device server will use the subnet mask to check whether the desired TCP/IP host specified in the packet is on the local network segment. If the address is on the same network segment as the device server, a connection is established directly from the device server. Otherwise, the connection is established through the gateway as specified in the “Gateway” parameter. Gateway Default Options IP address (e.g., “192.168.1.1”) Description This field is for the IP address of the gateway, if applicable. A gateway is a network computer that acts as an entrance to another network. Usually, the computers that control traffic within the network or at the local Internet service provider are gateway nodes. The NPort device server needs to know the IP address of the default gateway computer in order to communicate with the hosts outside the local network environment. Consult your network administrator if you do not know how to set this parameter.

NPort W2150A/W2250A Series Web Console: Network Settings 6-12 In Ad-hoc Mode

NPort W2150A/W2250A Series Web Console: Network Settings 6-13 In Infrastructure Mode You will need to configure Authentication and Encryption. These settings must match the settings on the wireless device at the other end of the connection (such as the AP). Different settings and options are available depending on how Authentication and Encryption are configured.

NPort W2150A/W2250A Series Web Console: Network Settings 6-14 Authentication Default Open System Options Open System, Shared Key, WPA, WPA-PSK, WPA2, WPA2-PSK Description This field specifies how wireless devices will be authenticated. Only authenticated devices will be allowed to communicate with the NPort. If a RADIUS server is used, this setting must match the setting on the RADIUS server. Open System: The NPort will simply announce a desire to associate with another station or access point. No authentication is required. For Ad-hoc Mode, this is the only option for authentication, since Ad-hoc Mode was designed for open communication. Shared Key: This option is only available in Infrastructure Mode. Authentication involves a more rigorous exchange of frames to ensure that the requesting station is authentic. WEP encryption is required. WPA: This is a managed authentication option that is only available in Infrastructure Mode. WPA was created by the Wi-Fi Alliance, the industry trade group that owns the Wi-Fi trademark and certifies devices with the Wi-Fi name. It is based on Draft 3 of the IEEE 802.11i standard. Each user uses a unique key for authentication, distributed from an IEEE 802.1X authentication server, also known as a RADIUS server. This option is also referred to as WPA Enterprise Mode, since it is intended to meet rigorous enterprise security requirements. Tunneled authentication is supported, depending on the EAP method selected. WPA-PSK: This is an unmanaged authentication option that is only available in Infrastructure Mode. Instead of a unique key for each user, a pre-shared key (PSK) is manually entered on the access point to generate an encryption key that is shared among all users. Consequently, this method does not scale well for enterprise. A PSK that uses a mix of letters, numbers and non-alphanumeric characters is recommended. This option is also referred to as WPA Personal Mode, since it is designed for the needs and capabilities of small home and office WLANs. WPA2: This is a managed authentication option that is only available in Infrastructure Mode. WPA2 implements the mandatory elements of 802.11i. Supported encryption algorithms include TKIP, Michael, and AES-based CCMP, which is considered fully secure. Since March 13, 2006, WPA2 has been mandatory for all Wi-Fi-certified devices. This option may also be referred to as WPA Enterprise Mode. Tunneled authentication is supported, depending on the EAP method selected. WPA2-PSK: This is an unmanaged authentication option that is only available in Infrastructure Mode. It employs WP2 encryption algorithms but relies on a PSK for authentication. A PSK that uses a mix of letters, numbers and non-alphanumeric characters is recommended. This option can also be referred to as WPA Personal Mode.

NPort W2150A/W2250A Series Web Console: Network Settings 6-15 Encryption Default Disable Options Disable, WEP, TKIP, AES-CCMP Description This field specifies the type of encryption to use during wireless communication. Different encryption methods are available depending on the Authentication setting. Also, each encryption method has its own set of parameters that may also require configuration. Disable: No encryption is applied to the data during wireless communication. This option is only available if Authentication is set to Open System. WEP: Wired Equivalent Privacy (WEP) is only available for Open System and Shared Key authentication methods. Data is encrypted according to a key. The NPort supports both 64 and 128-bit keys. This method may deter casual snooping but is not considered very secure. TKIP: Temporal Key Integrity Protocol (TKIP) is only available for WPA, WPA2, WPA-PSK, and WPA2-PSK authentication methods. TKIP is part of a draft standard from the IEEE 802.11i working group and utilizes the RC4 stream cipher with 128-bit keys for encryption and 64-bit keys for authentication. TKIP improves on WEP by adding a per-packet key mixing function to de-correlate the public initialization vectors (IVs) from weak keys. AES-CCMP: This is a powerful encryption method that is only available for WPA, WPA2, WPA-PSK, and WPA2-PSK authentication methods. Advanced Encryption Standard (AES) is the block cipher system used by the Robust Secure Network (RSN) protocol and is equivalent to the RC4 algorithm used by WPA. CCMP is the security protocol used by AES, equivalent to TKIP for WPA. Data undergoes a Message Integrity Check (MIC) using a well-known and proven technique called Cipher Block Chaining Message Authentication Code (CBC-MAC). The technique ensures that even a one-bit alteration in a message produces a dramatically different result. Master keys are not used directly but are used to derive other keys, each of which expire after a certain amount of time. Messages are encrypted using a secret 128-bit key and a 128-bit block of data. The encryption process is complex, but the administrator does not need to be aware of the intricacies of the computations. The end result is encryption that is much harder to break than even WPA. PSK Passphrase Default Options free text (e.g., “This is the WLAN passphrase”) Description This field is only available for WPA-PSK and WPA2-PSK authentication methods. If the NPort’s passphrase does not match the AP’s passphrase, the connection will be denied. A PSK of sufficient strength—one that uses a mix of letters, numbers and non-alphanumeric characters—is recommended.

NPort W2150A/W2250A Series Web Console: Network Settings 6-17 WEP Key Source Default Manual Options Manual, Generate WEP keys by passphrase Description This field specifies whether the WEP key will be generated manually or through a user-specified passphrase. A passphrase is equivalent to a free-text password that will be used to generate the WEP key. A passphrase is typically easier to remember and enter than a long and complicated WEP key. WEP Passphrase Default Options free text (e.g., “This is the WEP passphrase”) Description This field is only available if WEP key source is set to “Generate WEP keys by passphrase”. A standard hexadecimal password will be generated using the supplied passphrase. For example, if “404tech” is entered, the WEP key will be “DB971608E942FC39BD89FC4ADB”. WEP Key Format Default ASCII Options ASCII, HEX Description This field is only available if WEP key source is set to “Manual”. It specifies the format you will use to enter the WEP key. WEP Key 1 Through 4 Default Options free text in ASCII or HEX Description These fields are only available if WEP key source is set to “Manual”. Enter each WEP key in ASCII or HEX as specified in WEP key format. The number of characters required for each key depends on WEP key length and WEP key format. WEP Key Length WEP Key Format Key Length 64bits ASCII 5 characters HEX 10 characters 128bits ASCII 13 characters HEX 26 characters

NPort W2150A/W2250A Series Web Console: Network Settings 6-19 There are two parts to WPA and WPA2 security, authentication and data encryption. • Authentication occurs before access is granted to a WLAN. Wireless clients such as the NPort W2150A/W2250A Series are first authenticated by the AP according to the authentication protocol used by the RADIUS server. Depending on the WLAN security settings, an EAP tunnel can be used to scramble the username and password that is submitted for authentication purposes. • Encryption occurs after WLAN access has been granted. For all wireless devices, data is first encrypted before wireless transmission, using mutually agreed-upon encryption protocol. EAP Method Default PEAP Options TLS, PEAP, TTLS, LEAP Description This field specifies the EAP method to use for authentication. Four methods are supported. TLS: Transport Layer Security (TLS) was created by Microsoft and accepted by the IETF as RFC 2716: PPP EAP TLS Authentication Protocol. Passwords and tunneled authentication are not used. A user certificate and user private key are used to identify the NPort. The NPort’s user certificate and user private key must already be installed on the RADIUS server. PEAP: Protected Extensible Authentication Protocol (PEAP) is a proprietary protocol which was developed by Microsoft, Cisco and RSA Security. TTLS: Tunneled Transport Layer Security (TTLS) is a proprietary protocol which was developed by Funk Software and Certicom, and is supported by Agere Systems, Proxim, and Avaya. TTLS is being considered by the IETF as a new standard. For more information on TTLS, read the draft RFC EAP Tunneled TLS Authentication Protocol. LEAP: Lightweight Extensible Authentication Protocol (LEAP) is a proprietary protocol which was developed by Cisco. LEAP doesn’t check certificate during the authentication process. Tunneled Authentication Default PAP (when using TTLS) GTC (when using PEAP) Options GTC, MD5, MSCHAP V2 (when using PEAP) PAP, CHAP, MSCHAP, MSCHAP V2, EAP-MSCHAP V2, EAP-GTC, EAP-MD5 (when using TTLS) Description This field specifies the encryption method to use during the authentication process. Different methods are available depending on the EAP Method setting. Username Default Options free text (e.g., “Smith_John”) Description This field specifies the username that will be used to gain access to the WLAN. The correct username and password must be provided for access to be granted.

NPort W2150A/W2250A Series Web Console: Network Settings 6-20 Password Default Options free text (e.g., “Password123”) Description This field specifies the password that will be used to gain access to the WLAN. The correct username and password must be provided for access to be granted. Anonymous Username Default Options free text (e.g., “Anyuser”) Description This field specifies the anonymous username to use when initiating authentication. After the RADIUS Server has been verified by certificate, the true username and password will be used to complete the authentication process. Verify Server Certificate Default Disable Options Disable, Enable Description Disable: The certificate from the RADIUS server will be ignored. Enable: The certificate from the RADIUS server will be used to authenticate access to the WLAN. The RADIUS server’s trusted server certificate must already be installed on the NPort. To install a trusted server certificate, visit the corresponding page in the System Management> Certificate folder. Trusted Server Certificate This field is available for PEAP, TLS, and TTLS EAP methods only. It displays information on the trusted server certificate that is installed on the NPort. To install a trusted server certificate, visit the corresponding page in the System Management > Certificate folder. User Certificate This field is available only when EAP method has been set to TLS. It displays information on the user certificate that is installed on the NPort. To install a user certificate, visit the corresponding page in the System Management > Certificate folder. User Private Key This field is available only when EAP method has been set to TLS. It displays information on the user private key on the NPort.

NPort W2150A/W2250A Series Web Console: Network Settings 6-21 Advanced Settings On the Advanced Settings page in the Network Settings folder, you can modify Gratuitous ARP. Gratuitous ARP Default Disabled Options Disabled, Enabled, 10 to 1000 sec Description This field specifies how often the NPort sends broadcast packets to update the ARP table. This may be required for certain applications. Disabled: The NPort will not send broadcast packets to update the ARP table. Enabled: The NPort will send periodically send broadcast packets at the time interval as specified by Send period.

7 7. Web Console: Serial Port Settings The following topics are covered in this chapter:  Overview  Serial Port Settings  Communication Parameters  Data Buffering/Log

NPort W2150A/W2250A Series Web Console: Serial Port Settings 7-2 Overview This chapter explains how to configure all settings located under the Serial Port Settings folder in the NPort web console. Serial Port Settings Operation Modes Each serial port on the NPort is configured through the hyperlink below the column of Operating mode. Click the link of RealCOM, it will show the Port settings page. The Operation Modes page for each serial port is where you configure the serial port’s operation mode and related settings. For an introduction to the different operation modes, please refer to Chapter 4.

NPort W2150A/W2250A Series Web Console: Serial Port Settings 7-3 Operation Mode Default RealCOM Options RealCOM, RFC2217, TCP Server, TCP Client, UDP, Pair_Master, Pair_Slave, EModem Description Along with Application, this field specifies the serial port’s operation mode, or how it will interact with network devices. Depending on how Application is configured, different options are available for Mode. Depending on how Mode is configured, additional settings will be available for configuration. For an introduction to the different operation modes, please refer to Chapter 4. RealCOM: This serial port will operate in RealCOM mode. RFC2217: This serial port will operate in RFC2217 mode. TCP Server: This serial port will operate in TCP Server mode. TCP Client: This serial port will operate in TCP Client mode. UDP: This serial port will operate in UDP mode. Pair_Master: This serial port will operate in Pair Connection Master mode. Pair_Slave: This serial port will operate in Pair Connection Slave mode. EModem: This serial port will operate in Ethernet Modem mode.

NPort W2150A/W2250A Series Web Console: Serial Port Settings 7-4 Settings for RealCOM Mode When Operation Mode is set to RealCOM on a serial port’s Operation Modes page, you will be able to configure additional settings including TCP alive check time, Max connection, Ignore jammed IP, Allow driver Control, Connection goes down, Packet length, Delimiter 1, Delimiter 2, Delimiter process, and Force transmit. TCP Alive Check Time Default 7 min Options 0 to 99 min Description This field specifies how long the NPort will wait for a response to “keep alive” packets before closing the TCP connection. The NPort 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 NPort will force the existing TCP connection to close.

NPort W2150A/W2250A Series Web Console: Serial Port Settings 7-5 Max connection Default 1 Options 1 to 8 Description This field specifies the maximum number of connections that will be accepted by the serial port. 1: Only one specific host can access this serial port, and the RealCOM driver on that host will have full control over the port. 2 to 8: This serial port will allow the specified number of 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 NPort 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 NPort 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 or greater, the serial port’s communication settings (i.e., baudrate, parity, data bits, etc.) will be determined by the NPort. Any host that opens the COM port connection must use identical serial communication settings. Ignore jammed IP Default Disable Options Disable, Enable Description This field specifies how an unresponsive IP address is handled when there are simultaneous connections to the serial port. Disable: All transmission will be suspended if one IP address becomes unresponsive. Transmission will only resume when all hosts have responded. Enable: Data transmission to the other hosts will not be suspended if one IP address becomes unresponsive. Allow driver control Default Disable Options Disable, Enable Description This field specifies how the port will proceed if driver control commands are received from multiple hosts that are connected to the port. Disable: Driver control commands will be ignored. Enable: Control commands will be accepted, with the most recent command received taking precedence.

NPort W2150A/W2250A Series Web Console: Serial Port Settings 7-6 Connection goes down Default always high Options always low, always high Description This field specifies what happens to the RTS and DTR signals when the Ethernet connection goes down. For some applications, serial devices need to know the Ethernet link status through RTS or DTR signals sent through the serial port. Always low: The selected signal will change to low when the Ethernet connection goes down. Always high The selected signal will remain high when the Ethernet connection goes down. Packet length Default 0 Options 0 to 1024 Description This field specifies the maximum amount of data that is allowed to accumulate in the serial port buffer before sending. 0: Packet length is disregarded and data in the buffer will be sent as specified by the delimiter settings or when the buffer is full. 1 to 1024: Data in the buffer will be sent as soon it reaches the specified length. Delimiter 1 and 2 Default Disabled Options Disabled, Enabled, 00 to FF Description These fields are used to define special delimiter character(s) for data packing. Enable Delimiter 1 to control data packing with a single character; enable both Delimiter 1 and 2 to control data packing with two characters received in sequence. When these fields are enabled, serial data will accumulate in the serial port’s buffer until the buffer is full or until the specified delimiter character(s) are received. For example, the carriage return character could be used as a delimiter in order to transmit each sentence or paragraph in a separate packet. Data will be packed according to Delimiter process. Delimiters must be incorporated into the data stream at the software or device level. ATTENTION When Delimiter 1 is enabled, Packet length must be set to 0.

NPort W2150A/W2250A Series Web Console: Serial Port Settings 7-7 Delimiter process Default Do Nothing Options Do Nothing, Delimiter + 1, Delimiter + 2, Strip Delimiter Description This field specifies how data is packed when delimiter characters are received. This field has no effect if Delimiter 1 is not enabled. Do nothing: Data accumulated in the serial port’s buffer will be packed, including delimiters. Delimiter + 1: One additional character must be received before the data in the serial port’s buffer is packed. Delimiter + 2: Two additional characters must be received before the data in the serial port’s buffer is packed. Strip Delimiter: Data accumulated in the serial port’s buffer will be packed, but the delimiter character(s) will be stripped from the data. Force transmit Default 0 ms Options 0 to 65535 Description This field controls data packing by the amount of time that elapses between bits of data.
