We cover Wiring Requirements, Connecting the Power, Connecting to the Network, Connecting to a Serial Device, and LED Indicators. 2-2 NPort W2004 User’s Manual Getting Started Wiring Requirements ATTENTION Safety First! Be sure to disconnect the power cord before installing and/or wiring your device. Wiring Caution! 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. Temperature Caution! Be careful when handling the device. When plugged in, the device’s internal components generate heat, and consequently the casing may feel hot to the touch. You should also pay attention to the following items: Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the intersection point. NOTE: Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid interference, wires with different signal characteristics should be routed separately. Use the type of signal transmitted through a wire to determine which wires should be kept separate. The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together. Keep input wiring and output wiring separate. Where necessary, it is advisable to label the wiring to all devices in the system. Connecting the Power Connect the 12-48 VDC power line with NPort W2004’s power jack. When the power is supplied properly, the “Ready” LED will show a solid red color until the system is ready, at which time the “Ready” LED will change to a green color. Connecting to the Network Connect one end of the Ethernet cable to NPort W2004’s 10/100M Ethernet port and the other end of the cable to the Ethernet network. If the cable is properly connected, NPort W2004 will indicate a valid connection to the Ethernet in the following ways: The Ethernet LED maintains a solid green color when connected to a 100 Mbps Ethernet network. The Ethernet LED maintains a solid orange color when connected to a 10 Mbps Ethernet network. The Ethernet LED will flash when Ethernet packets are being transmitted or received. 2-3 NPort W2004 User’s Manual Getting Started Connecting to a Serial Device Connect the serial data cable between NPort W2004 and the serial device. Serial data cables are optional accessories for NPort W2004.

The options include an operation mode that uses a driver installed on the host computer, and operation modes that rely on TCP/IP socket programming concepts. After choosing the proper operation mode in this chapter, refer to Chapter 5 for detailed configuration parameter definitions. This chapter covers the following topics: Overview TCP Server Mode TCP Client Mode UDP Mode Real COM Mode NPort W2004 User’s Manual Choosing the Proper Operation Mode Overview NPort W2004 wireless Serial Device Servers are used to network-enable traditional RS-232/422/485 devices. A Serial Device Server is a tiny computer equipped with a CPU, real-time OS, and TCP/IP protocols that can bi-directionally translate data between the serial and Ethernet formats. The Serial Device Server lets you use a computer to access, manage, and configure remote facilities and equipment over the Internet from anywhere in the world. Traditional SCADA and data collection systems rely on serial ports (RS-232/422/485) to collect data from different types of instruments. Since NPort W2004 wireless Serial Device Servers network-enable instruments equipped with an RS-232/422/485 communication port, your SCADA and data collection system will be able to access all instruments connected to a standard TCP/IP network, regardless of whether the devices are used locally or at a remote site. NPort W2004 is an external IP-based network device that allows you to expand the number of serial ports for a host computer on demand. As long as your host computer supports the TCP/IP protocol, you won’t be limited by the host computer’s limited number of conventional busses (such as ISA or PCI), or lack of drivers for various operating systems. In addition to providing socket access, NPort W2004 also comes with a Real COM/TTY driver that transmits all serial signals intact. This means that you can continue using existing COM/TTY-based software, eliminating the need to invest in additional, costly software. Three different Socket Modes are available: TCP Server, TCP Client, and UDP Server/Client. 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 lets you unicast to one IP address, or multicast to groups of IP addresses. TCP Server Mode TCP/IP WLAN 1 Request a connection 2 Proceed with data transmission Device Server This operation mode also supports up to 4 simultaneous connections, so that multiple hosts can collect data from the same serial device—at the same time. TCP Server Mode Ready WLAN P1 P2 P3 P4 Signal Strength Ethernet NPort W2004 RS-232 Console P4 P3 RS-232/422/485 In TCP Server mode, NPort W2004 is configured with a unique IP:Port address on a TCP/IP network. NPort W2004 waits passively to be contacted by the host computer, allowing the host computer to establish a connection with and get data from the serial device. P2 P1 NPort W2004 Serial Device As illustrated in the figure, data transmission proceeds as follows: Serial (TTL) 1. The host requests a connection from the NPort W2004 configured for TCP Server Mode. 2. Once the connection is established, data can be transmitted in both directions—from the host to the NPort W2004, and from the NPort W2004 to the host. 4-2 NPort W2004 User’s Manual Choosing the Proper Operation Mode TCP Client Mode TCP Client Mode TCP/IP WLAN After the data has been transferred, NPort W2004 can disconnect automatically from the host computer by using the TCP alive check time or Inactivity time settings.

P2 P1 NPort W2004 Serial Device Serial (TTL) 1. The NPort W2004 requests a connection to the host. 2. Once the connection is established, data can be transmitted in both directions—from the host to the NPort W2004, and from the NPort W2004 to the host. UDP Mode UDP Mode TCP/IP WLAN Device Server Compared to TCP communication, UDP is faster and more efficient. In UDP mode, you can unicast or multicast data from the serial device to one or more host computers. The serial device can also receive data from multiple host computers, making this mode ideal for message display applications.

The WLAN driver establishes a transparent connection between host and serial device by mapping the IP:Port of the NPort W2004’s serial port to a local COM port on the host computer. One of the main conveniences of using Proceed directly with data Real COM Mode is that Real COM transmission (connection NPort W2004 Mode allows users to continue using request not required) RS-232/422/485 serial communications software that was written for pure serial Serial (TTL) Serial Device communications applications. The driver intercepts data sent to the host’s COM port, packs it into a TCP/IP packet, and then redirects it through the host’s Ethernet card. At the other end of the connection, the NPort W2004 accepts the Ethernet frame, unpacks the TCP/IP packet, and then transparently sends it to the appropriate serial device attached to one of the NPort W2004’s serial ports. Ready WLAN P1 P2 P3 P4 Signal Strength Ethernet RS-232 Console P4 RS-232/422/485 P3 P2 P1 NPort W2004 ATTENTION Real COM Mode allows several hosts to have access control of the same NPort W2004. The driver that comes with your NPort W2004 controls host access to attached serial devices by checking the host’s IP address. Refer to Accessible IP Settings in Chapter 5 for more details. 4-4 5 Chapter 5 Web Console Configuration The Web Console is the most user-friendly method available to configure NPort W2004 Series.

Note that the login function cannot be disabled. 5. The NPort W2004 homepage will open. On this page, you can see a brief description of the Web Console’s nine function groups. ATTENTION If you can’t remember the password, the ONLY way to start configuring NPort W2004 is to load factory defaults by using the Reset button, which is located near the NPort W2004’s power jack. ATTENTION If you use a web browser other than Internet Explorer, remember to Enable the functions to “allow cookies that are stored on your computer” or “allow per-session cookies.” NPort W2004 uses cookies only for “password” transmission. 5-3 NPort W2004 User’s Manual Web Console Configuration Time Settings NPort W2004 has a built-in Real-Time Clock that allows you to add real-time information to functions such as Auto warning “Email” or “SNMP Trap.” ATTENTION First time users should select the time zone first. The Console will display the “real time” according to the time zone compared to GMT. If you would like to modify the real time clock, select “Local time.” NPort W2004’s firmware will modify the GMT time according to the Time Zone. Time zone Setting User selectable time zone Local tim (yy/mm/dd)e Setting Factory Default Necessity GMT (Greenwich Mean Time) Optional Factory Default Necessity User adjustable time GMT (Greenwich Mean Time) Optional (2000/1/1-2037/12/31) Click on the [ Modify ] button to open the Modify time settings window to input the correct local time. 5-4 NPort W2004 User’s Manual Time server Setting IP Address or Domain Name (E.g., 192.168.1.1, time.stdtime.gov.tw, or time.nist.gov) Web Console Configuration Factory Default Necessity None Optional NPort W2004 uses SNTP (RFC-1769) for auto time calibration. Input the correct “Time server” IP address or domain name. Once NPort W2004 is configured with the correct Time server address, NPort W2004 will request time information from the “Time server” every 10 minutes. Network Settings General Settings Click on the General Settings option to modify the Server name and DNS server IP addresses or domain names. Server name Setting Alphanumeric DNS server 1 / DNS server 2 Setting E.g., 192.168.1.1 (IP addresses of the form x.x.x.0 and x.x.x.255 are invalid. Factory Default Necessity NPW2004_Optional Factory Default Necessity None Optional When a user wishes to visit a particular website, the computer first requests the website’s correct IP address from the Domain Name System (DNS) server, and then the computer uses the response to connect to the website. DNS represents the method used to translate Internet domain names into IP addresses. A domain name is an alphanumeric name, such as moxa.com, that it is easier to remember. A DNS server is a host that translates this kind of text-based domain name into the numeric IP address used to establish a TCP/IP connection. 5-5 NPort W2004 User’s Manual Web Console Configuration In order to use NPort W2004’s DNS feature, you need to configure the DNS server. Doing so allows NPort W2004 to use a host’s domain name to access the host. NPort W2004 provides DNS server 1 and DNS server 2 configuration items to configure the IP address of the DNS server. DNS Server 2 is included for use when DNS sever 1 is unavailable. Ethernet Configuration You must assign a valid IP address to NPort W2004 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, NPort W2004 will not have a valid connection to the network). First time users should refer to Chapter 3, “Initial IP Address Configuration,” for more information. Choose from two possible “IP configuration” modes—Static and DHCP—located under the web console screen’s IP configuration drop-down box. IP configuration Method Function Definition Static User defined IP address, Netmask, Gateway. DHCP DHCP Server assigned IP address, Netmask, Gateway, DNS, and Time Server. IP address Setting E.g., 192.168.1.1 (IP addresses of the form x.x.x.0 and x.x.x.255 are invalid. Factory Default Necessity 192.168.126.254 Required 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. Netmask Setting E.g., 255.255.255.0 Factory Default Necessity 255.255.255.0 Required 5-6 NPort W2004 User’s Manual Web Console Configuration A netmask is used to group network hosts into subnets. When a packet is sent out over the network, the NPort W2004 will use the netmask to check whether the desired TCP/IP host specified in the packet is on the same subnet as the NPort. If the address is on the same subnet, a connection is established directly between the NPort W2004 and the host. If the host is not on the same subnet, the packet is sent to the Gateway address. Gateway Setting E.g., 192.168.1.1 Factory Default Necessity None Optional A gateway is a network gateway 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. NPort W2004 needs to know the IP address of your network’s default gateway computer in order to communicate with the hosts outside the local network environment. For correct gateway IP address information, consult your network administrator. ATTENTION In Dynamic IP environments, the firmware will make 3 requests to the DHCP server every 30 seconds until network settings are assigned by the DHCP server. The Timeout for each try increases from 1 second, to 3 seconds, to 5 seconds. If the DHCP Server is unavailable, the firmware will use the default IP address (192.168.126.254), Netmask, and Gateway for IP settings. WLAN Configuration Network Configuration NPort W2004 supports the IEEE 802.11b wireless network interface. The supported IP configurations are static and dynamic (DHCP). Users can set up the IP configuration via the serial console, or the Web/Telnet consoles through the NPort’s Ethernet 5-7 NPort W2004 User’s Manual Web Console Configuration interface. For detailed information about configuring IP configuration, IP address, Netmask, and Gateway, see the previous section, “Ethernet Configuration.” Wireless LAN You may choose from two different WLAN modes—Infrastructure Mode and Ad-hoc Mode— which are illustrated in the following diagrams. Ad-hoc Mode In the following example, two NPort W2004 devices establish an Ad-hoc peer-to-peer relationship, which means that they communicate with each other directly, without going through an AP (Access Point). Infrastructure Mode In the following example, the NPort W2004 communicates with the host computer via the AP. The host computer connects to the AP via an Ethernet connection, allowing serial data to be transmitted back and forth between the serial devices and host computer. 5-8 NPort W2004 User’s Manual Web Console Configuration SSID Enter the name of the wireless network (SSID) that the W2004 is connected to. Channel Select a radio channel for the wireless network from the pull-down menu. In infrastructure mode, the AP will specify the channel automatically. In Ad-hoc mode, the user must use the pull-down menu to specify the channel. ATTENTION Click on the Wizard to configure the WLAN IP address quickly. Security The wireless network interface supports data encryption (WEP, 64 or 128 bits) and authentication (Open or Shared authentication). Authentication Select an authentication scheme of Open or Shared from the pull-down menu. WEP Mode By default, WEP Mode is disabled. When WEP Mode is enabled, data packets will be encrypted before send .you can select 64-bit or 128-bit. WEP Key 1/2/3/4 For each of the four WEP Keys, select either ASCII or HEX format, and then enter the appropriate WEP Key. The WEP Keys are used to help prevent data from being stolen as it is transmitted over public networks. The WEP Key setting(s) for the NPort W2004 must be the same as the WEP Key settings for the AP. 5-9 NPort W2004 User’s Manual Web Console Configuration Serial Port Settings Serial port settings are configured by port. Operation Modes The Serial Port parameters that appear in the right pane of the browser window when Serial Port Settings # Port 1/2/3/4 # Operation Modes is selected are dependent on which of the four operation modes is selected. We consider each operation mode separately. Real COM Mode Port 1/2/3/4 Max connection Setting 1, 2, 3, 4 Factory Default Necessity Required Max connection is usually used when the user needs to receive data from different hosts simultaneously. The factory default is 1. In this case, only one specific host can access this port of the NPort W2004, and the Real COM driver on that host will have full control over the port. Max connection 1 Allows only 1 host’s Real COM driver to open the specific NPort W2004 serial port. Max connection 2 to 4: Allows 2 to 4 host’s Real COM drivers to open the specific NPort W2004 serial port, at the same time. When multiple hosts’ Real COM drivers open the serial port at the same time, the COM driver only provides a pure data tunneling without control ability. Application software that is based on the COM driver will receive a driver response of “success” when the software uses any of the Win32 API functions. The firmware will only send the data back to the driver on the host. Data will be sent first-in-first-out when data comes into the NPort W2004 from the Ethernet interface. 5-10 NPort W2004 User’s Manual Web Console Configuration ATTENTION When Max connection is set to 2, 3, or 4, NPort W2004 will use a “multi connection application” (i.e., 2, 3, or 4 hosts are allowed access to the port at the same time). When using a multi connection application, NPort W2004 will use the serial communication parameters set in the console. All of the hosts connected to that port must use the same serial settings. If one of the hosts opens the COM port with parameters that are different from NPort W2004’s console setting, data communication may not work properly. Data Packing Delimiter 1/2 Setting 00 to FF (hex) Factory Default Necessity None Optional Once the NPort W2004 receives both delimiters through its serial port, it immediately packs all data currently in its buffer and sends it to the NPort W2004’s Ethernet port. ATTENTION Delimiter 2 is optional. If left blank, then Delimiter 1 alone trips clearing of the buffer. If the size of the serial data received is greater than 1 KB, the NPort W2004 will automatically pack the data and send it to the Ethernet. However, to use the delimiter function, you must at least enable Delimiter 1. If Delimiter 1 is left blank and Delimiter 2 is enabled, the delimiter function will not work properly. Force transmit Setting 0 to 65535 ms Factory Default Necessity Optional 0: Disable force transmit timeout. 1 to 65535: Forces the NPort W2004’s TCP/IP protocol software to try to pack serial data received during the specified time into the same data frame. This parameter defines the time interval during which NPort W2004 fetches the serial data from its internal buffer. If data is incoming through the serial port, NPort W2004 stores the data in the internal buffer. NPort W2004 transmits data stored in the buffer via TCP/IP, but only if the internal buffer is full or if the Force transmit time interval reaches the time specified under Force transmit timeout. The optimal Force transmit timeout depends on your application, but it must be at least larger than one character interval within the specified baud rate. For example, assume that the serial port is set to 1200 bps, 8 data bits, 1 stop bit, and no parity. In this case, the total number of bits needed to send a character is 10 bits, and the time required to transfer one character is ( 10 (bits) / 1200 (bits/s) ) * 1000 (ms/s) = 8.3 ms. Therefore, you should set Force transmit to be larger than 8.3 ms, so in this case, it must be greater 5-11 NPort W2004 User’s Manual Web Console Configuration than or equal to 10 ms. If you want to send a series of characters in the same packet, the serial device attached to NPort W2004 should send that series of characters during a time interval less than the Force transmit timeout, and the total length of data must be less than or equal to NPort W2004’s internal buffer size. The serial communication buffer size for NPort W2004 is 1 KB per port. TCP Server Mode Port 1/2/3/4 Inactivity time Setting 0 to 65535 ms Factory Default Necessity 0 ms Optional 0 ms: TCP connection is not closed due to an idle serial line. 0-65535 ms: NPort W2004 automatically closes the TCP connection if there is no serial data activity for the given time. After the connection is closed, NPort W2004 starts listening for another host’s TCP connection. This parameter defines the maintenance status as Closed or Listen for the TCP connection. The connection is closed if there is no incoming or outgoing data through the serial port during the specific Inactivity time. If the Inactivity time is set to 0, the current TCP connection is kept active until a connection close request is received. Although Inactivity time is disabled, the NPort W2004 will check the connection status between the NPort W2004 and remote host by sending “keep alive” packets periodically. If the remote host does not respond to the packet, NPort W2004 assumes that the connection was closed down unintentionally. NPort W2004 will then force the existing TCP connection to close. 5-12 NPort W2004 User’s Manual Web Console Configuration ATTENTION The Inactivity time should be set at least larger than that of Force transmit timeout. To prevent the unintended loss of data due to the session being disconnected, it is highly recommended that this value is set large enough so that the intended data transfer can be completed. Max connection Setting 1, 2, 3, 4 Factory Default Necessity Required Max connection is usually used when the user needs to receive data from different hosts simultaneously. The factory default is 1. In this case, only one specific host can access this port of the NPort W2004, and the Real COM driver on that host will have full control over the port. Max connection 1 Allows only 1 host’s Real COM driver to open the specific NPort W2004 serial port.

The serial communication buffer size for NPort W2004 is 1 KB per port. TCP Server Mode Local TCP Port Setting 1 to 65535 Factory Default Necessity 4001 Required The “Local TCP port” is the TCP port that NPort W2004 uses to listen to connections, and that other devices must use to contact NPort W2004. To avoid conflicts with well known TCP ports, the default is set to 4001. 5-14 NPort W2004 User’s Manual Command port Setting 1 to 65535 Web Console Configuration Factory Default Necessity 966 Optional The “Command port” is a listen TCP port for IP-Serial Lib commands from the host. In order to prevent a TCP port conflict with other applications, the user can set the Command port to another port if needed. IP-Serial Lib will automatically check the Command Port on NPort W2004 so that the user does not need to configure the program. TCP Client Mode Port 1/2/3/4 TCP alive check time Setting 0 to 99 min Factory Default Necessity 7 min Optional 0 min: TCP connection is not closed due to an idle TCP connection. 1 to 99 min: NPort W2004 automatically closes the TCP connection if there is no TCP activity for the given time. After the connection is closed, NPort W2004 starts listening for another host’s TCP connection. Inactivity time Setting 0 to 65535 ms Factory Default Necessity 0 ms Optional 0 ms: TCP connection is not closed due to an idle serial line. 5-15 NPort W2004 User’s Manual Web Console Configuration 0-65535 ms: NPort W2004 automatically closes the TCP connection if there is no serial data activity for the given time.
