Connecting the Hardware

ATTENTION

Before connecting the hardware, follow these important wiring safety precautio ns :

Disconnect power source

Do not install or wire this unit or any attached device s with the pow er connected. Disconnect the power before installation by removing the power cor d bef or e installing and/or wiring your unit.

Follow maximum curre nt ratings

Calculate the maxim um pos sible current in each power wire and common wir e . 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 be too hot to touch. Take care when handling the unit. Be sure to leave adequate space for ventilatio n.

The following guidelines will help e ns ure tr o uble -f re e sig n al communic ation with the NPort.

• Use separate paths to route wiring for power and devices to avoid interfer ence. Do not run signal or

communication wiring and power wiring in the same wire conduit. The r ule of thumb is that wir ing that shares similar electrical characteristics can be bundled toge t h er.

• 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 Seri e s Getting Started

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 conne ction to the Ethernet as follows:

• A green Ethernet LED indicates a valid connection to a 100 Mbps Etherne t ne twork .

• An orange Ethernet LED indicates a valid connectio n to a 10 Mbps Ether ne t ne twor k .

• A flashing Ethernet LED indicates that Ethernet packets are being trans mitte d or re c e ive d .

Connecting the Power

Connect the VDC power line (12 to 48 V) to the NPort’s power jack or terminal block (recommended for only one connection at a time). If power is proper ly conne c t e d , the “R e a dy ” LED w ill 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.

Overview

This chapter presents sev er a l way s to a s s ign the NPort’s IP address for the firs t time . Ple ase re fe r to Chapter 2 for instructions on connec ting 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 configuratio n.

ATTENTION

The LAN and WLAN interfaces cannot be used at the same time if you don't enable the Ethernet Bridge mode (please refer to Chapter 7 for mor e details ). If the Ethernet link is active, then WLAN connectio ns 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 befor e pow er ing up the NPor t.

Factory Default IP Settings

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 de fault IP address and netmask.

ATTENTION

If you forget the IP address of yo ur NPort, you can look it up using the Device Se arc h U tility (DSU). After the Device Search Utility (DSU ) has fo und all NPorts on the network, each unit will be listed with its I P address. Please refer to Ch apte r 11 for additional information on using the Dev ic e S e arc h Utility (DSU).

Using ARP to Assign an 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 re co nfigured. This method only works when the NPort is configured with default I P setting s .

1. Select a valid IP address for your NPor t. Co nsult with your network administrator if ne ces sar y .

2. Obtain the NPort’s MAC address from the label on its bottom panel.

3. From the DO S 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 00-90E8-xx-xx-xx is the NPor t’ s MAC addr ess .

4. From the DOS prompt, execute a special Te lne t co mmand using po rt 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.

The NPort will automatically reboot with the new IP addre s s. You c a n ver ify that the c o nfigur atio n was successful by connecting to the new IP address with Telnet, ping, the web console, or the Device Search Utility (DSU).

Using the Telnet Console to an 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 c lick [OK].

Using the Serial Console to an Assign IP Address

Before using the NPort’s serial c o nso le , turn off the power and use a serial cable to connect the NPort console port to your computer’s s er ial 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 ANSI or VT100, and the serial communication parameters should be set as 19200, 8, N, 1 (19200 fo r b a ud rate, 8 for data bits, None for parity, and 1 for stop b its). As soo n as the co nne c tio n is open, you will b e presented with a text menu display ing the NPor t W2150A/W2250A Series general setting s . Ple ase refer to Chapter 4 for a description of the available setting s .

NPort W2150A/W2250A Series Introduction to Operation Modes

Overview

This chapter introduces the different serial port operation modes that are available on the NPort W2150A/W2250A Series . Each se rial port on the NPort is configured independ ently of the other ports, with its own serial communication parameters and oper ation 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.

Real COM 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-d ev eloped socket programs: TCP Serve r , 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 guarantee s delivery of data by requiring the recip ie n t to se nd an acknowledgement to the sende r . UD P does not re q uire this typ e of ver ification, making it possible to offer speedier delivery. UDP also allows multicasting of data to gro u p s of IP addresses and would be suitab le for streaming media or noncritical messaging applic atio ns such as LED messag e board s .

Pair Connection Slave and Master modes are designed for serial-to-serial communication over Ethernet, in order to overcome traditional limitations w ith se rial transmission distance.

In Ethernet Modem mode, the NPort acts as an Ethernet modem, providing a network connection to a host through the serial port.

Real COM Mode

Real COM 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 UNI X sys te m s . The driver establishes a transparent connec tion to the attached serial device by mapping a local serial port to the NPort serial port. Real COM mode supports up to four simultaneous connectio ns , so multiple hosts can collect data from the attached device at the same time.

ATTENTION

Real COM drivers are installed and config ur ed thro ugh NPort Windows Driver Manager.

Real COM mode allows you to continue using your ser ial communicatio ns s of tw a re to access devic e s that ar e now attached to your NPort device server. On the host, the NPort Real COM driver automatically intercepts data sent to the COM port, packs it into a TCP/IP packet, and redirec ts it to the network . At the other e nd of the connection, the NPort device server acce pts the Ethernet frame, unpacks the TCP/IP packet, and sends the serial data to the appropr iate dev ice.

NPort W2150A/W2250A Series Introduction to Operation Modes

ATTENTION

In Real COM 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 Real COM mode, s ince it re lie s o n a drive r to trans p ar e ntly 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 compute r to establish a connection to the attached serial device. This operation mode also supports up to e ight simultaneous connections, so multiple hos ts 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 direct io ns—from the host to the device, and from the device to the host.

TCP Client Mode

In TCP Client mode, the NPort actively establishe s a TCP connection to a specific network host when data is received from the attache d se r ia l device. After the data has been transferred, the NPort can automatically disconnect from the host computer through the Inactivity time settings. Pleas e re fe r to Chapter 7 for details on these parameters . Data transmission proceeds as follows: The NPort requests a connection from the hos t. The connection is established and data can be transmitted in both direct io ns betw e e n the host and device.

NPort W2150A/W2250A Series Introduction to Operation Modes

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 no t support verification of da ta and would no t be suitable for applications wh ere d ata integ rity is critical. It is ideal for message dis p lay app lic ations.

Pair Connection Modes

Pair Connection Master and Slave modes connect two NPort device se rvers over a network for serial-toserial 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 communic ation 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 pro perly configured NPort serial port to the MS -DO S computer’s serial port, it is possible to use legacy software to transmit data over the Ether ne t when the software was originally designed to transmit data over a modem.

3. NPort Windows Driver Manager will list each available serial port and will automatically assign a new COM port to each one. The new COM port will not be accessible by the hos t syste m until it has be e n activated in NPort Windows Driver Manager . Activ a ting a mapped CO M port sav es the informatio n in the host system registry and makes the COM port available for use. Click Yes to activate the COM port(s) at this time; click No to activate the COM port(s) later.

4. Activated COM ports will b e listed in black; COM ports that have not been activ a te d w ill be listed in blue. Once a COM port has been activated, the host computer will be able to communica te w ith the new CO M port as if it were physically attached. Since the COM mappings are stored in the host system registry, they will still be in effect if the PC is restarted or if Wind ow s Drive r Manag er is clo se d .

NPort W2150A/W2250A Se ri e s Installing and Configuring the Software

3. On the Advanced Setting tab, configure Tx Mode, FIFO, and Fast Flush.

Tx Mode: In Hi-Performance mode, the driver immediately issues a “Tx Empty” response to the

program after sending data to the NPort. In Classical mode, the driver se nds the “ Tx Empty” response after confirmation is received from the NPort. Classical mode is recommended if you want to ensure that all data is sent out before further processing.

FIFO: This tells the driver whether or not to use the FIFO. Network Timeout: You can use this option to prevent blocking if the target NPort is unavailable. Fast Flush: When enabled, the driver flushes only the local buffer on the host for a Win32

PurgeComm() function call. When disab led, bo th the lo c al and re mo te b uffers are flushed. If your application uses PurgeComm() and perfor manc e seem s sluggis h, try enabling Fast Flush.

Auto Network Re-Connection: With this option enabled, the driver will repeate d ly attemp t to re establish the TCP connection if the NPort does not respo nd to backg ro und “c heck-alive” packets

Always Accept Open Req uests: When enabled, the NPort driver will always accept requests to open a virtual COM port, even if communications with the device can not be established. With this option, the NPort driver will agree to open a virtual COM port on the system even if the port is blocked or the Ethernet connection is disabled . If this is the case, the co nnecte d d evic e will not receive and transmit data even though the system has opened a virtual COM port.

5-14

NPort W2150A/W2250A Se ri e s Installing and Configuring the Software

Drop Writing Data if Network Connection is Lost: This function will assure the data to be kept in the

buffer or dropped when networ k c o nnec tio n is los t. The b uffe r size is 4 KBytes. Return error if network is unavailable: If this option is disabled, the dr ive r w ill no t retur n any error

even when a connection cannot be established to the NPor t. With this option enabled, calling the Win32 Comm function will result in the e rror return code “STATUS_NETWORK_UNREACHABLE” when a connection cannot be established to the NPor t. 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 NPort is not powered on or is disconnected. Not that Auto Network Re-Connection must be enabled in order to use this function.

Ignore TX Purge

Applications can use the Win32 API PurgeCom m to clear the o utp ut buffer. Outstanding overlapping write operations will be terminated. Select the Ignore TX Purge checkbox to ignore the effect on output data.

4. On the Serial Parameters tab, specify the communication settings that the host will use when opening the COM port.

5-15

5. On the Security tab, select the Enable Data Encryption option to enable da ta to be encr yp ted when transmitted over the COM ports. Af ter sele c ting the encryption option, select the Keep connection option to start encrypting COM port communic atio ns immediately without restarting the COM ports. This may speed up opening and closing of the COM port for your host, but it also causes your host to tie up the NPort serial port so other hosts cannot use it.

6. On the IPv6 Setting tab, interface 1 and 2 are able to change.

7. Click OK when you have f inis hed co nfiguring the COM port

Linux Real TTY Drivers

Real TTY driver are provided that will map Linux host TTY ports to NPort serial por ts . Once the mapp ing has been set up, Linux users and applications can connect to a serial port as if it were a local TTY port. The se drivers have been designed and te s ted for the major ity of Linux distributions, including Linux kernel version

2.4.x, 2.6.x, and 3.x, 4.x. Please check http://www.moxa.com

Basic Steps

Follow these instructio ns to map a TTY por t to an NPort serial port:

1. Install the NPort device server and set the target dev ic e port to Real COM mode.

2. Install the Real TTY driver files on the Linux host.

3. Map the host’s TTY port to the target dev ic e po rt on the NPort.

Installing Linux Real TTY Driver Files

Before proceeding with the softw a re ins tallatio n, make sure you have completed the NPort devic e server has been installed and configured correctly. Note that the default LAN IP address for the NPort is

192.168.126.254, whereas the default WLAN IP address is 192.168.127.254.

for the latest Linux kernel supported.

ATTENTION

The target serial port must be operating in Real COM mode in order to map TTY ports.

1. Obtain the driver file from https://www.moxa.com/support/support_home.aspx?isSearchShow=1

2. Log in to the console as a super user (root).

3. Execute cd / to go to the root directory.

5-19

NPort W2150A/W2250A Se ri e s Installing and Configuring the Software

4. Copy the driver fi le npreal2xx.tgz to the / directory.

5. Execute tar xvfz npreal2xx.tgz to extract all files into the system.

6. Execute /tmp/moxa/mxinst. (For Red Hat AS/ES /W S an d F e dora Core1, execute “# /tmp/moxa/mxinst SP1”.) The shell script will install the dr iver files automatically.

7. After installing the driver , yo u will b e ab le to see seve ral files in the /usr/lib/npreal2/driver folder:

mxaddsvr (add server, map TTY port) mxdelsvr (delete server, undo TTY port mapping) mxloadsvr (reload s erver ) mxmknod (create device node/TTY port) mxrmnod (remove device node/TTY port ) mxuninst (remove TTYport and driver files)

At this point, you may map the TTY port to the NPort serial port.

Mapping TTY Ports

Make sure that you set the operation mode of the de s ire d NPo rt serial port to Real COM mode. After logg ing in as a super user, enter the directory /usr/lib/npreal2/driver and then execute mxaddsvr to map the target NPort serial port to the host TTY ports. The syntax of mxaddsvr is as follows:

mxaddsvr [NPort IP Address] [Total Ports] ([Data port] [Cmd port]) The mxaddsvr command performs the following actions:

1. Modify npreal2d.cf.

2. Create TTY ports in directory /dev with major and minor number configured in npreal2d.cf.

3. Restart the driver.

Mapping TTY ports automa ticall y

To map TTY ports automatically, you may execute mxaddsvr w ith just the IP address and number of ports, as in the following example:

# cd /usr/lib/npreal2/driver # ./mxaddsvr 192.168.3.4 16

In this example, 16 TTY ports will be added, all with IP 192.168.3.4, with data ports from 950 to 965 and command ports from 966 to 981.

Mapping TTY ports manuall y

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/npreal2/driver # ./mxaddsvr 192.168.3.4 16 4001 966

In this example, 16 TTY ports will be added, all with IP 192.168.3.4, with data ports from 4001 to 4016 and command ports from 966 to 981.

Removing Mapped TTY Ports

After logging in as root, enter the directory /usr/lib/npreal2/driver and then execute mxdelsvr to delete a server. The syntax of mxdelsvr is:

mxdelsvr [IP Address] Example:

# cd /usr/lib/npreal2/driver # ./mxdelsvr 192.168.3.4

The following actions are performed when executing mxdelsvr:

5-20

NPort W2150A/W2250A Se ri e s Installing and Configuring the Software

1. Modify npreal2d.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 dr ive r files, mapped TTY ports, and unload the driver. Enter the directory /usr/lib/npreal2/driver and 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/npreal2.

3. Delete directory /usr/lib/npreal2.

4. Modify the system initializing scr ip t file .

UNIX Fixed TTY Drivers

A fixed TTY driver is provided that will map UNIX host TTY por ts to NPor t serial po r ts . Once the mapping has been set up, UNIX users and applications can connect to an NPort serial port as if it were a local TTY port. This driver has been designed and tested for the majority of UNIX systems. Please check

http://www.moxa.com

for the latest UNIX systems support.

Installing the UNIX Driver

1. Log in to UNIX and create a directory for the MOXA TTY. To create a dire c tory named /usr/etc, execute the command:

# mkdir –p /usr/etc

2. Copy moxattyd.tar to the directory you created. For the /usr/etc directory, you would execute the following commands:

# cp moxattyd.tar /usr/etc # cd /usr/etc

3. Extract the source files from the tar file by executing the command :

# tar xvf moxattyd.tar

The following files will be extrac ted:

README.TXT moxattyd.c --- source code moxattyd.cf --- an empty configuration file Makefile --- makefile VERSION.TXT --- fixed TTY driver version FAQ.TXT

4. Compile and link. For SCO UNIX:

# make sco

NPort W2150A/W2250A Se ri e s Installing and Configuring the Software

Configuring the UNIX Driver

Modify the configura tio n:

The configuration used by moxattyd is defined in the text file moxattyd.cf, which is in the same directory. You may use vi or any text editor to modify the file, as follows:

ttyp1 192.168.1.1 950

You can refer to moxattyd.cf for detailed descriptions of the v ar io us conf iguration parameters. Please note that Device Name depends on the OS. See the Device Naming Rule section in README.TXT fo r more information.

To start the moxattyd daemon after sys te m bo o tup, add an entry into /etc/inittab using the TTY name you defined in moxattyd.cf, as in the following example:

ts:2:respawn:/usr/ etc/moxattyd/mox at tyd –t 1

Device naming rule

For UnixWare 7, UnixWare 2.1.x, and SVR4.2, use: pts/[n]

For all other UNIX operating syste ms , use : ttyp[n]

The value of [n] should be equal or larger than 11 in ord er to pr ev e nt co nflicts with the device names of functional keys in some UNIX systems.

Starting moxattyd Execute the command in it q or reboot your UNIX operating system.

Adding an additional serve r

Modify the text file moxattyd.cf to add an additional server. Users may use vi or any text editor to modify the file. For more configuration inf or m atio n, refer to moxattyd.cf, which contains detailed descriptions of the various configuration parameters.

Find the process ID (PID) of the moxattyd.

# ps -ef | grep moxattyd Update the configuration of moxattyd.

# kill -USR1 [PID]

(e.g., if moxattyd PID = 404, kill -USR1 404) This completes the proce s s of adding an additional server.

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 Setting s fo lde r, y o u can mod ify DNS serve r 1 and 2.

DNS Server 1 and 2

Default Options IP address (e.g., “192.16 8.1.1”) Description This field is for the DNS server’ s I P addr ess, 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 us er ’ s computer send s 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.

Ethernet/Bridge Settings

To enable the Ethernet-to-Wireles s func tio n, als o c alle d Wire le s s Client, go to the Ethernet/Bridge Settings page and enable Ethernet Bridge. When it's enabled, the LAN and WLAN will use the same IP

configuration (use the same IP address, netmask and g ateway s e ttings).

ATTENTION

In dynamic IP environments, the NPort w ill send thre e r eq uests ev e ry 30 seconds to the DHCP or BOOTP server until the network settings have succ ess fully been assigned. The first request will time out after one second; the second request will time out after thre e se conds , and the thir d req ue s t will timeo ut afte r five second. If the DHCP or BOOTP server is unavailable , the NPort will use the f a c tory def ault ne tw ork settings.

NPort W2150A/W2250A Se ri e s Web Console: Network Se tti ngs

Ethernet Bridge

Default Disabled Options Enabled, Disabled Description This field specifies whether to enable Ethernet Bridge mode or not. When Ethernet

Bridge is enabled, the LAN and WLAN interfaces are bridged together. Data can be seamlessly transferred between serial lines, LA N, and WLAN. The LAN and WLAN will use the LAN IP setting, and WLAN IP setting will be disabled.

Disabled: When disabled, you can use either the LAN or WLAN. Enabled: When enabled, you can use both the LAN and the WLAN.

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 -d ef ine d . DHCP: IP address, netmask, gateway, DNS, and time server are assigned by the DHCP

server. DHCP/BOOTP: IP address, netmask, gateway, DNS, and time server are assigned by the

DHCP server. IP address is assigned by BOOTP server if DHCP server does not respond. BOOTP: IP address is assigned by the BOOTP server.

IP Address

Default 192.168.126.254 Options IP address (e.g., “192.16 8.1.1”) Description This field is for the IP address that will b e ass igned to your NPort device server. An IP

address is a number assigned to a network device (such as a compute r ) as a permane nt address on the network. Computers use the IP address to identify and talk to each other over the network. Choose a prop er I P addr es s 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 Se ri e s Web Console: Network Se tti ngs

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 (LAN). When a packet is sent out over the network, the NPort device server will use the subnet mask to check whether the desired TCP/I P ho s t spec ified in the packet is on the local network segment. If the address is on the same network segme nt as the devic e serv er, a connection is established directly from the device server. Otherwise, the connec tion is established through the gateway as specif ied in the Gateway parameter.

Gateway

Default Options IP address (e.g., “192.16 8.1.1”) Description This field is for the IP address of the g ate w ay , if app lic ab le. 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 lo c al I nter ne t se rv ic e pr ovider 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 lo c al network e nvironment. Consult your network administrator if you do not know how to se t this parame te r.

Options Auto, 802.11a, 802.11b/g, 802.11a/n, 802.11b/g/n Description This field determines whic h wir e le s s st and ard w ill be us ed by the sele c ted pro file. 802.11a,

802.11b/g, 802.11a/n and 802.11b/g/n are supported. Auto: In Ad-hoc Mode, the NPort will scan the 2.4G wirele s s b and and w ill automatically

select the appropriate wireless standard for communication with any other wireless devices that are detected. In Infrastructure Mode, the NPort will auto matically select between 802.11a, 802.11b/g, 802.11a/n and 802.11b/g/n according to the settings of the AP.

802.11a: The Unlicensed National I nformation Infrastructure (UNII) 5 GHz band is used for communication, which is different fro m the RF ba nd used by 802.11b and 802.11g. Consequently, 802.11a devices w ill not be able to communicate with 802.11b or 802.11g devices. (Multi-mode 802.11 a/b/g A Ps or clie nt ad apte r s can be use d to re solve this.) Transmission rates up to 54Mbps are supported.

802.11b/g: This option means our device will support for 802.11b or 802.11g.

802.11b: This is the well-known “Wi-Fi” standard, also referred to as “802.11 High-Rate (HR).” Wireless communication is in the 2.4 GHz ISM band , using the DS SS spre ad spectrum transmission sch eme. 802.11b support s data rates of 1 Mbps, 2 Mbps, 5.5 Mb p s , and 11 Mbps.

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.

7-16

NPort W2150A/W2250A Se ri e s Web Console: Network Se tti ngs

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 NPor t. If a RADIU S serv e r is use d , this se tting must match the setting on the RADIUS server.

Open System: The NPort will simply announce a desire to asso c iate with ano the r s tation or access point. No authentication is re q u ire d . For Ad -hoc Mode, this is the only option for authentication, since Ad-hoc Mode wa s desig ned for open co mmunic ation.

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 requir ed .

WPA: This is a managed authentication option that is only available in Infrastructure Mode. WPA was created by the Wi-Fi Alliance, the industry trad e gro up that owns the Witrademark 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 authe nticatio n, d is tr ibuted 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. Tunne le d authe n tic ation is supported, depending on the EAP method selected.

WPA-PSK: This is an unmanaged authentication op tion that is only available in Infrastructure Mode. Inste a d of a uniq ue k ey for e a c h user, a pr e -s hare d ke y (PS K) is manually entered on the access point to gener ate an en cryp tion key that is shared among all users. Consequently, this method do e s not scale well for enterprise. A PSK that uses a mix of letters, numbers and non-alphanumeric c harac te rs is r eco mmend ed. This op tio n 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 A ES-bas ed CCMP, which is cons id er e d fully s ecur e . Since March 13, 2006, WPA2 has been mandatory for all Wi-Fi-ce rtified devices. This option may also be referred to as WPA Enterpr ise Mod e . Tunneled authentication is supported, depending on the EAP method selected.

WPA2-PSK: This is an unmanaged authentication optio n that is only availab le in Infrastructure Mode. It employ s WP2 encry p tion algorithms but relies on a PSK for authentication. A PSK that uses a mix of letters, number s and non-alp hanume ric characters is recommended. This option can also be referred to as WPA Personal Mode.

7-17

NPort W2150A/W2250A Se ri e s Web Console: Network Se tti ngs

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 parameter s that may also req uire co nf igur ation.

Disable: No encryption is applied to the data d uring wire less communication. This option is only available if Authentication is set to Open System.

WEP: Wired Equivalent Privacy (WEP) is only av ailable for Open System and Shared Key authentication methods. Data is enc rypted according to a key. The NPort supports bo th 64 and 128-bit keys. This method may deter casual s nooping but is not considered very secure.

TKIP: Temporal Key Integrity Pro tocol (TKIP) is only available for WPA, WPA2, WPA-PSK, and WPA2-PSK authentication methods. TKIP is part of a draft s tand ard fr o m the IEEE

802.11i working group and utilizes the RC4 stream cipher with 128-bit keys for encryption and 64-bit keys for authenticatio n. TKIP improves on WEP by adding a per-packet ke y mixing function to de-corre late the pub lic 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 . Adva nc ed Enc ry p tion 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 ca lle d C ipher B loc k C haining Message Authentication Code (CBC-MAC). The technique ensures that even a one-bit alteration in a message produces a dramatically different r e s ult. Mas ter keys ar e not use d dire ctly but are used to derive other keys, each of which exp ir e afte r a cer tain amount of time. Messages are encrypted using a secret 128-bit key and a 128-bit block of data. The e ncr yption process is complex, but the administrator does not ne ed to be aware of the intr ic ac ie s 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 passphras e”) Description This field is only available for WPA-PSK and WPA2-PS K authenticatio n me thods. If the

NPort’s passphrase does not match the AP’s passphras e , the connec tion will be denied. A PSK of sufficient strength—one that uses a mix of letters, numbers and non-alphanumeric characters—is recommended.

When Encryption is set to WEP on the Security page for the WLAN profile, you will be able to configure WEP key length, WEP key index, and WEP key source. Other settings will be displayed depending on how WEP key source is configured.

WEP Key Length

Default 64bits Options 64bits, 128bits Description This field specifies the le ngth of the WEP key. 64b its is the industry standard for WEP, but

128bits provid e s be tte r protection.

WEP Key Index

Default 1 Options 1 through 4 Description This field specifies the primary WEP key to use for the WLAN.

WEP Key Source

Default Manual Options Manual, Generate WEP keys by passphrase Description This field specifies whether the WEP key w ill be gener ated 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 re member and enter than a long and complicated WEP key.

WEP Passphrase

Default Options free text (e.g., “This is the WEP passphras e”) Description This field is only available if WEP key so urc e is se t 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”.

There are two parts to WPA and WPA2 security , authentica tio n , and data e ncr yp tio n .

• Authentication occurs before access is granted to a WLAN. Wireless clients such as the NPort W2150A/W2250A Series are first authe n tic ate d by the AP acco rd ing to the authentication protocol used by the RADIUS server. Depending on the WLAN sec urity 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 us e fo r authe ntic ation. 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 priv ate key are used to identify the NPort. The NPort’s user certificate and user pr ivate key mus t already be installed on the RADIUS server.

Serial Port Settings

Operation Modes

Each serial port on the NPort is configured thro ugh the hyperlink below the column of Operating mode.

Click the link of Real COM, it will show the Por t se tting s page. The Operation Modes page for each s er ial port is where you configure the serial port’s operation mode and related settings. For an introduc tion to the different operation modes, please refer to Chapter 4.

8-2

NPort W2150A/W2250A Series Web Console: Serial Port Settings

Operation Mode

Default Real COM Options Real COM, RFC2217, TCP Server, TCP Client, UDP, Pair_Master, Pair_Slave, EMode m Description Along with Application, this field specifies the serial port’s operation mode, or how it will

interact with network devices . Dep e nd ing on how Applic ation is configured, different options are available for Mode. Depend ing o n how Mode is configured, additional settings will be available for configuration. Fo r an introduction to the different operatio n mode s , please refer to Chapter 4. Real COM: This serial port will operate in Real COM mode.

RFC2217: This serial po rt will operate in RFC2217 mode. TCP Server: This serial port will oper ate in TCP Server mode. TCP Client: This serial port will operate in TCP Client mod e . UDP: This serial port will operate in UDP mode. Pair_Master: This serial port will oper ate in Pair Co nne c tio n Master mod e . Pair_Slave: This serial port will oper ate in Pair Co nne c tio n Slave mode . EModem: This serial port will operate in Ether ne t Modem mode.

8-3

NPort W2150A/W2250A Series Web Console: Serial Port Settings

Settings for Real COM Mode

When Operation Mode is set to Real COM 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 NPor t c heck s conne ctio n s tatus by send ing p er iod ic “keep- a l i ve” packets .

0: The TCP connection will remain open even if there is no respo n s e to the “k eep -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.

8-4

NPort W2150A/W2250A Series Web Console: Serial Port Settings

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 Real COM 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 conne c tions, the Real COM driver will only provide a pure data tunnel with no control ability. The serial communic ation will be determined by the NPort rather than by your application program. Application software that is based on the Real COM driver will receive a driver response of “success” when using any of the Win32 API functions. The NPort will se nd data only to the Real C O M driv er on the ho s t. Data received from hosts will be sent to the attached serial device on a first-in-first-out basis.

ATTENTION

When Max connection is two or greater, the serial port’s communication settings (i.e., baudrate, parity, data bits, etc.) will be determined by the NPor t. 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 addre s s is hand led when ther e 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 hos ts hav e res po nd ed. 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 mos t rece nt co mmand rec e ive d

taking precedence.

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, ser ial 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 Etherne t co nne c tio n go es down.

8-5

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 spe c ified length.

Delimiter 1 and 2

Default Disabled Options Disabled, Enabled, 00 to FF Description These fields are used to define special delimiter charac ter(s) f or data pac k ing. 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 delimite r cha r a cter(s) are received. For exam p le , the carriage return character could be used as a delimiter in order to transmit each sentence or paragraph in a separate pack et. Data will be packed according to Delimiter process.

Delimiters must be incorporate d into the data stream at the software or device level.

ATTENTION

When Delimiter 1 is enabled, Packet length must be set to 0.

Delimiter process

Default Do Nothing Options Do Nothing, Delimiter + 1, Delimiter + 2, Strip Delimiter Description This field specifies how data is pack ed whe n de limite r characters are received. This field

has no effect if Delimiter 1 is not enabled. Do nothing: Data accumulated in the serial port’s buff er will be pack ed, inc lud ing

delimiters. Delimiter + 1: One additional character mus t be rec e ive d bef ore 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 str ip p ed fro m the data.

0: If serial data is not received, the NPort will wa it ind ef inite ly for additional data. 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 ex ample, assume that the ser ial por t is set to 1200 bps, 8 data bits, 1 stop bit, and no parity. I n this ca s e, the total number of bits needed to send a character is 10 bits, and the time re q uired to transfer one character is

8.3 ms, so the force transmit time to be larger than 8.3 ms.

Settings for UDP Mode

8-16

NPort W2150A/W2250A Series Web Console: Serial Port Settings

When Operation Mode is set to UDP on a serial port’s Operation Modes page, yo u will b e able to configure additional settings such as Destination address 1 through 4, Local listen port, Packet length,

Delimiter 1, Delimiter 2, Delimiter process, and Force transmit.

Destination addres s 1 to 4

Default Options IP address range and port (e.g., “192.168.1.1” to “192.168.1.64” and “4001”) Description In UDP mode, you may specify up to four ranges of IP addresses for the ser ial port to

connect to. At least one destination range must be provid ed. The maximum selectable IP address range is 64 addresses. However, you can enter

multicast addresses in the Begin field, in the form xxx.xxx.xxx.255. For example, enter “192.127.168.255” to allow the NPort to broadcast UDP packets to all hosts with IP addresses between 192.127.168. 1 and 192.127.168.254.

Local listen port

Default 4001 Options Description This field specifies the UDP port that the NPort lis te ns to and that o ther device s must use

to contact the attached serial device.

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 spe c ified length.

Delimiter 1 and 2

Default Disabled Options Disabled, Enabled, 00 to FF Description These fields are used to define special delimiter charac ter(s) f or data pac k ing. 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.

Delimiters must be incorporate d 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

Delimiter process

Default Do Nothing Options Do Nothing, Delimiter + 1, Delimiter + 2, Strip Delimiter Description This field specifies how data is pack ed whe n de limite r 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 mus t be rec e ive d bef ore 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 str ip p ed fro m 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.

When using this field, make sure that Inactivity time is dis abled or set to a larger value. Otherwise the connectio n may be clos e d be fo re the data in the buffer can be transmitted.

0: If serial data is not received, the NPort will wait indefinitely for additional data. 1 to 65535: If serial data is not received fo r the sp ecified amount of time, the data that is

currently in the buffer will be pac ked fo r ne two rk 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 ex ample, assume that the ser ial por t is set to 1200 bps, 8 data bits, 1 stop bit, and no parity. I n this ca s e, the total number of bits needed to send a character is 10 bits, and the time re q uired to transfer one character is

8.3 ms, so the force transmit time to be larger than 8.3 ms.

Settings for Pair Connection Master Mode and Pair Connection Slave Mode

8-18

NPort W2150A/W2250A Series Web Console: Serial Port Settings

When Operation Mode is set to Pair Connection Master or Pair Connection Slave on a serial port’s Operation Modes page, you will be able to configure additional settings such as TCP alive check time, Destination addre ss and TCP port. A Pair Connection application involves one serial port communicating

over an IP network to another serial port as if the two serial ports were connected by a serial cable. Pair Connection modes can be used to extend RS-232 transmission to unlimited distances.

An NPort device server is needed at both ends of the connection. The serial port at one end must be set to Pair Connection Master mode, and the serial port at the other end must be set to Pair Connection Slave mode. It does not matter which serial port is master and which serial port is slave .

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 p er iod ic “keep-alive” packets.

0: The TCP connection will remain open even if there is no respo n s e to the “k eep -alive” packets.

1 to 99: If the remote host does not respon d to the p ack e t within the sp e c ified time, the NPort will force the existing TCP connec tio n to c los e.

Destination addres s

Default Options IP address and port (e.g., “192.16 8 .1 .1” and “4001”) Description This field specifies the IP ad dre s s for the N Port at the opposite end of the Pair Connectio n,

and the TCP port number for communication with the serial port. The port numb er must match with that serial port’s TCP port setting.

TCP port

Default 4001 Options Description This field specifies the TCP port to use for communicatio n with the attached serial device.

The serial port at the opposite end of the Pair Co nne c t io n must use this por t numbe r to establish the connection.

NPort W2150A/W2250A Series Web Console: Serial Port Settings

Settings for Ethernet Modem Mode

When Application is set to Ethernet Modem Mode, the NPort will accept AT commands such as “ATD

192.127.168.1:4001” from the serial port. A TCP connection will then be requested from the specified

remote Ethernet Modem or PC. When the remote unit accepts this TC P conne c tion, the NPort will return the “CONNECT {baudrate}” signal to the serial port and will then enter data mode. Please refer to Appendix C for details on Ethernet modem commands.

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 p er iod ic “keep-alive” packets.

0: The TCP connection will remain open even if there is no respo n s e to the “k eep -alive” packets.

1 to 99: If the remote host does not respon d to the p ack e t within the sp e cified time, the NPort will force the existing TCP connection to close.

TCP port

Default 4001 Options Description This field specifies the TCP port to use for communicatio n with the attached serial device.
