ATTENTION

Safety First!

Be sure to disconnect the power cord before installing and/or wiring your NPort Device Server.

Wiring Caution!

Calculate the maximum possible current in each power 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!

Please be cautious when handling the NPort device server. When plugged in, the NPort’s internal components generate heat, and consequently the casing may feel hot to the touch. When installed with other components, make sure that there is at least 2 cm clearance on all sides of the NPort device server in order to allow proper heat dissipation.

Installing Your NPort Device Server

This section describes how to connect an NPort device server to your serial devices for the first time. We cover Wiring Requirements, Connecting the Power, Grounding the NPort Device Server, Connecting to the Network, Connecting to a Serial Device, and LED Indicators.

Wiring Requirements

You should observe the following:

• 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.

• You can 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 sh a res similar electrical characteristics can be bundled together.

• Keep input wiring and output wiring separate.

• Where necessary, it is strong ly advised that you label wiring to all devices in the system.

wire and common wire. Observe all electrical codes

Connecting the Power

Connect the power line with the NPort’s power inp u t. If the power is properly supplied, the “Ready” LED will show a solid red color until the system is ready, at which time the “Read y” LED will change to a green color.

Grounding the NPort Device Server

Note: This section only applies if your NPort’s power input is on a terminal block. Grounding and wire routing help limit the effects of noise caused by electromagnetic interference (EMI ). Run

RS-485 Port’s Adjustable Pull High/Low Resistor

For some applications you may need to use termination resistors to prevent the reflection of serial signals. When u sing termination resistors, it is important to set the pull h igh/low resistors correctly so that the electrical signal is not corrupted. Refer to Appendix B for detailed instructions on how to set the pull high/low resistor values for different models.

Configuration by Windows Utility

NPort Administration Suite is an integrated software suite that bundles NPort Administrator and the IP Serial Library, providing everything you need to manage, monitor, and modify your NPort from a remote location.

With NPort Administrator, you can easily install and configure your NPort device server over the network. Five different sets of functions are provided to ease the installation process: Configuration, Monitor, Porting Monitor, COM Mapping, and IP Address Report.

In this section we will cover only the “configuration of general settings” using NPort Administrator. For more detailed information on how to use this suite of useful utilities, refer to Chapter 5.

You may also use the web console, serial console, or Telnet to configure the device server. Refer to the section

Configuration by Web Console, Configuration by Serial Console, and Configuration by Telnet Console for additional information on using these consoles.

Installing NPort Administrator

Locate and run the setup program on the NPort Document & Software CD. Look for a file named Npadm_Setup_[Version]_Build_[DateTime].exe (e.g., “Npadm_Setup_Ver1.8_ Build_07041316.exe”). You may also download the latest version of NPort Administrator from Moxa’s website at: http://www.moxa.com/support/download.aspx?d_id=1317

Run NPort Administrator when the installation is complete.

Searching for Device Servers over a LAN

The Broadcast Search function is used to locate all NPort 5400 device servers that are connected to the same LAN as your computer. Since the Broadcast Search function searches by MAC address and not IP address, all NPorts connected to the LAN will be located, regardless of whether or not they are part of the same subnet as the host.

NPort 5000 Series Getting Started

2-8

In NPort Administrator, click Search to search your LAN for NPort device servers. When your unit appears in the search results, you may click Stop to end the search. You may also wait a few more moments for the search to complete.

The Configuration screen will list the NPort device servers that were found on the LAN. If your unit cannot be found, you may have a n etwork problem. Check all cables and verify that your PC and device server are on the same LAN. If you still have problems, try connecting the device server directly to your PC.

Adjusting General Settings

Right-click your unit in the Configuration screen and select Configure in the popup menu. If your device server is password protected, first select Unlock in the popup menu, and then cl ick the Network tab in the configuration window. Select the Modify checkbox for items you would like to modify. The device server must be assigned a unique IP address that is valid for your network. Both fixed and dynamic IP addresses are supported. Consult with your network administrator if you are not sure how to set these parameters.

When you are ready to restart the device server with the new settings, click OK.

NPort 5000 Series Getting Started

2-9

Static IP Addresses

For most applications, you will assign a fixed IP address to the device server. To assign a static (fixed) IP address, the IP Configuration parameter must be set to “Static”, which is the default setting. You may then modify the IP Address and Netmask parameters.

Dynamic IP Addresses

For certain network environments, your device server’s IP address will be assigned by a DHCP or BOOTP server. In this case, instead of assigning the device server’s IP address, you will need to configure the device server to receive its IP address from the appropriate server. Set the IP Configuration parameter to “DHCP”, “BOOTP”, or “DHCP/BOOTP”, depending on your network environment. The IP Address and Netmask parameters will be unavailable for editing since these parameters will be assigned automatically.

If you are not sure whether you need to configure your device server for a dynamic or static IP address, consult the administrator who se t u p the LAN.

Verifying Network Settings

If your device server has been configured correctly, you should be able to ping its IP address from your PC. First make sure that your PC and device server are on the same subnet, and then ping the device server’s address. If no response is received, check your ca bles and network settings.

Configuring Device Port Operation Mode

This section covers configuration of a device port’s operation mode. The operation mode determines how the device port will interact with the network. Which operation mode you select will depend on your specific application. Refer to the chart at the end of this section for guidance on selecting the most appropriate operation mode. For additional information on each operation mode, refer to Chapter 3 and Chapter 4.

Adjusting Operation Mode Settings

The operation mode parameters for each device port can be configured through NPort Administrator. Open your device server’s configuration window using the same method you used to adjust the network parameters. On the Operating Mode screen, select the Modify chec k box and then select the device port that you wish to configure. Click Settings to configure the selected device port.

Mapping COM Port to Device (only required when operation mode is set to Real COM or RFC2217)

This section covers how to map the COM ports on a Windows PC to NPort device ports. The mapping will allow Windows software to access serial devices over the network as if they were local COM devices, providing instant device networking without software migration. COM mapping is supported in Real COM and RFC2217 modes only.

The following instructions are for device ports operating in Real COM mode. For device ports operating in RFC2217 mode, follow the instructions for your particular driver. Real COM mode also supports TTY port mapping on Linux and UNIX systems.

Specifying the Target Device Server

In NPort Administrator, click COM Mapping in the Function panel to open the COM Mapping window. Right-click an empty line in the COM Mapping window and select Add Target in the pop-up menu to assign your device server as the mapping target.

A list of NPort device servers that have been found by NPort Administrator will appear. Select your device server and click Finish.

Assigning COM Port Number to Device Port

The COM Mapping screen shows a list of available device ports on the network. Right-click the target device port and select COM Settings in the pop-up menu.

On the Basic Settings screen, select the COM port number that will be mapped to t h e device port. You can map multiple COM ports at the same time by selecting the Auto Enumerating check box to number the COM ports automatically.

On the Serial Parameters screen, adjust the settings to ma tch your device. These settings, which are only used for serial printers, must also match the settings on the device port. Click OK when you are satisfied with your changes.

Advanced Settings

(See Chapter 5 for detailed information about NPort Administrator’s Advanced Settings.) 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 sends the “Tx E mp ty” 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: Tells the driver whether or not to use FIFO transmission. Network Timeout: Specifies when an open, close, or serial parameter change operation will time out. Fast Flush: When enabled, the driver flushes only the local buffer on the host for a Win32 PurgeComm()

function call. When disabled, both the local and remote buffers are flushed. If your application uses PurgeComm() and performance seems sluggish, try enab ling Fast Flush.

Always Accept Open Requests: Even if the driver cannot establish a connection with the NPort, the user's software will still be able to open the mapped COM port, the same as with an onboard COM port.

Ignore TX Purge: The application can use Win32 API PurgeComm to clear the output buffer and terminate outstanding overlapped write operations. Selecting Ignore TX Purge if you do not want the output buffer to be purged.

IP Address Report

When NPort products are used in a dynamic IP environment, users must spend more time with IP management tasks. For example, if the NPort works as a server (TCP or UDP), then the host, which acts as a client, must know the IP address of the server. If the DHCP server assigns a new IP address to the NPort, the host must have some way of determining the NPort’s new IP address.

NPort products help out by reporting their IP address periodically t o the IP location server, in case the dynamic IP has changed. The parameters shown below are used to configure the Auto IP report function. There are two ways to develop an “Auto IP report Server” to receive NPort’s Auto IP report.

1. Use D evice Server Administrator’s IP Address Report function.

2. Auto IP report protocol, which can receive the Auto IP report automatically on a regular basis, is also available to help you develop your own software. Refer to Appendix E for details about the Auto IP report

3. Choosing the Proper Operation Mode

In this chapter, we describe the NPort device server’s various operation modes. 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 4 for detailed configuration parameter definitions.

The following topics are covered in this chapter:

The NPort Windows systems, and also TTY drivers for Linux systems. The driver establishes a transparent connection serial device by mapping the IP:Port of the

serial port to a local COM/TTY port on the host computer. Real COM Mode also supports up to 4 simultaneous hosts can collect data from the

t the same

time.

ATTENTION

The driver used for Real COM Mode is bundled with NPort Administrator. The driver is installed on your computer automatically when you instal l NPort Administrati on Suite.

Overview

NPort serial device servers network-enable traditional RS-232/422 /485 devices. A serial device server is a small computer equipped with a CPU, real-time OS, and TCP/IP protocols that can bi-directiona lly tr an slate data between the serial and Ethernet formats. NPort device servers that are connected to a network that with access to the Internet can be accessed from a computer located anywhere in the world.

Traditional SCADA and data collection systems rely on serial ports (RS-232/422/485) to collect data from various kinds of instruments. Since NPort serial device servers network-enable instruments equipped with an RS-232/422/485 communication p ort, 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.

An NPort serial device server 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 protoc ol, you won’t be limited by the host computer’s bus limitation (such as ISA or PCI), or lack of drivers for various operating systems.

In addition to providing socket access, the NPort also comes with a Real COM / TTY driver that transmits all serial signals intact. This means that you c an conti nue usi ng your existing COM/TTY-based software, without needing to invest in additional software.

Three different socket modes are av a ilable: TCP Server, TCP Client, and U DP 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 also allows data to be unicast t o only one IP addre ss, or multic ast to groups of IP addresses.

One of the major conveniences of using Real COM Mode is that Real COM Mode allows users to continue using RS-232/422/485 serial communications software that was written for pure serial 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 NPo r t accepts the Ethernet frame, unpacks the TCP/IP packet, and then sends it transparently to the appropriate serial device attached to one of the NPort’s serial ports.

RFC2217 Mode is only supported by the NPort 5000A, NPort 5000AI-M12, NPort IA5000A, NPort 5600, and NPort 5600-8-DT/DTL Series.

RFC 2217 mode is similar to Real COM mode in that a driver is used to establish a transparen t co nnection between a host computer and a serial device by mapping the serial port on the NPort to a local COM port on the host computer. RFC2217 defines general COM port control options based on the Telnet protocol. Third party drivers supporting RFC2217 are widely available on the Internet and can be used to implement Virtual COM mapping to your NPort serial port(s).

Pair Connection Mode

Pair Connection Mode employs two NPort units in tandem, and can be used to remove the 15-meter distance limitation imposed by the RS-232 interface. One NPort is connected from its RS-232/422/485 port to the COM port of a PC or other type of computer, such as hand-held PDAs that have a serial port, and the serial device is connected to the RS-232/422/485 port of the other NPort. The two NPort units are then connected to each other with a cross-over Ethernet cable, both are connected to the same LAN, or in a more advanced setup, they communicate with each other over a WAN (i.e., through one or more routers). Pair Connection Mode transparently transfers both data and modem control signals (although it cannot transmit the DCD signal) between the two NPorts.

Ethernet Modem Mode

Ethernet Modem Mode is only supported by the NPort IA5000/IA5000A, NPort 5000A, NPort 5000AI-M12, and NPort 5100 series.

Ethernet Modem Mode is designed for use with legacy operating systems, such as MS-DOS, that do not support TCP/IP Ethernet. By connecting one of NPort’s serial ports to the MS-DOS computer’s serial port, it is possible to use legacy software originally designed to transmit data via modem, but now transmit the data over the Ethernet.

NPort 5000 Series Choosing the Proper Operation Mode

3-5

Reverse Telnet Mode

Console management is commonly used by connecting to Console/AUX or COM ports of routers, switches, and UPS units. Rtelnet works the same as TCP Server mode in that only one TCP port is listened to after booting up. The system then waits for a host on the network to initiate a connection. The difference is that the TCP Server mode does not provide the conversion function provided by Telnet. If the connected devices need to use the CR/LF conversion function when controlling, then users must choose Reverse Telnet mode.

Disabled Mode

When the Operation Mode for a particular port is set to Disabled, that port will be disabled.

Overview

A device port’s operation mode determ ines how the port interacts with the network. Depending on your application and device, you may have the option of choosing between two or more operating modes. For each mode, the default settings should work for most applications. Modify these settings only if absolutely necessary for your application. The operation mode and related parameters can be configured through NPort Administrator. The same parameters may also be configured using the web co nsole, Telnet console, or serial console.

Using Pair Connection Modes

For some applications, you may want to configure two serial devices to communicate directly with each other over the network. This can be done with a pair of NPort device servers configured for Pair Connection Master/Slave modes. Configure one device port on one of the NP orts to Pair Connection Master mode, and one device port on the other NPort to Pair Connection Slave mode. It doesn’t matter which NPort is the master and which NPort is the slave.

For the device port configured for Pair Connection Slave mode, designate a Local TCP port to be used for communication. For the device port configured for Pair Connection Master mode, enter the slave’s IP address and Local TCP port as the Destination IP.

Once both device ports have been configured, the attached serial devices will communicate over Ethernet as if they were connected by a serial cable. The two NPorts can be connected by an Ethernet cable, or they can be connected to the same network.

Parameter Summary

Connection Management Parameters

Reverse Telnet Mode

Inactivity time

Reverse Telnet Mode

TCP alive check time

Setting Options: 0 to 99 minutes Default: 7 minutes

Description: The time limit for keeping the connection open if a host does not respond to “TCP alive check” packets. If the host does not respond within the specified time, the connection will be closed. A setting of 0 means that the connection will rema in open even if the host never responds.

Setting Options: 0 to 65535 ms Default: 0

Description: Specifies the time limit for keeping the connection open if no data flows to or from the serial device. If there is no activity for the specified time, the connection w ill be closed. A setting of 0 means that the connection will remain open ev en if data is never received.

For many applications, the serial device may be idle for long periods of time, so 0 is an appropriate setting. If you TCP Client mode, you must set Connection Control to Any Character/Inactivity Time (see Connection Control).

When adjusting Inactivity time, make sure that it is greater than the Force transmit time. Otherwise, the TCP connection may be closed before data in the buffer can be transmitted.

Data Packing Parameters

Packing length

Setting Options: 0 to 1024 Default: 0

Description: Controls data packing by the amount of data received. Serial data accumulates in the device port’s buffer until it reaches the specified length. When the specified amount of data has accumulated in the buffer, the data is packed for network transmission. A setting of 0 means that data will not be packed until the buf f er is full. 0 is the recommended setting, unless your application has a specific need to limit packet sizes or improve response times.

Delimiter 1 and 2

Setting Options: Enable, 0 to FF Default: Disable

Description: Controls data packing using special delimiter character(s). Serial data accumulates in the devi ce p ort’s buffer until the delimiter

character(s) are received, after which the data is packed for network transmission. If only one delimiter character is needed, be sure to enable Delimiter 1 only. If both Delimiter 1 and 2 are enabled, both characters

carriage return character could be used as a delimiter in order to transmit each sentence or paragraph in a separate packet. Data is packed according to the Delimiter process parameter.

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

Delimiter process

Setting Options: Do Nothing, Delimiter + 1, Delimiter + 2, Strip Delimiter Default: Do Nothing

Description: Controls how data is packed when delimiter c ha racters are received. Note that this field has no ef f ect if delimiters are not enabled (see Delimiters 1 and 2).

”Do nothing” will pack the accumulated data including delimiters. ”Delimiter + 1” will wait for an additional character before packing the

accumulated data. ”Delimiter + 2” will wait for two additional characters before packing

accumulated data. ”Strip Delimiter” will pack the accumulated data but will not include the

delimiter characters in the packet.

Reverse Telnet Mode

Force transmit

Setting Options: 0 to 65535 ms Default: 0 ms

Description: Controls data packing by the amount of time that elapses between bits of data. As serial data is r eceived, it accumulates in the

of time, the data that is currently in the buffer is packed for network transmission. A setting of 0 means that data in the buffer will not be automatically packed when additional data is not received from the device. When using this field, make sure Inactivity time is disabled or set to a larger value. Otherwise, the connection may be closed before the data in the buffer can be transmitted.

UDP Multicast (for the NPort 5000A/IA5000A only)

A multicast is a packet sent by one host to multiple hos ts. In multicast mode, each host that belongs to a specific multicast group will receive multicast packets for that group. For a host to be configured as a multicast receiver over the Internet, the mu st inform the routers on its LAN. The Internet Group Ma n agement Protocol (IGMP) is used to communicate group membership information between hosts and routers on a LAN. The NPort 5000A/IA5000A supports IGMP version 2.

Type the IP address (e.g., 239.1.1.1) assigned to the multicast group in the Begin column. The NPort will automatically add the Group, and receive all packets from this group as required by the multicast function.

Pair Connection Mode

Pair Connection Mode employs two NPort device servers in tandem, and can be used to remove the 15-meter distance limitation imposed by the RS-232 interface. One NPort is connected from its RS-232 port to the COM port of a PC or other type of computer, such as a hand-held PDA, and the serial device is connected to the RS-232 port of the other NPort. The two NPort device servers are then connected to each other with a cross-over Ethernet cable, both are connected to the same LAN, or in a more advanced setup, they communicate with each other over a WAN (i.e., through one or more routers). Pair Connection Mode transparently transfers both data and modem control signals (although it cannot transmit the DCD signal) between the two NPort device servers.

Pair Connection Master Mode

When using Pair Connection Mode, you must select Pair Connection Master Mode for the Operation mode of one of the NPort device servers. In ef fect, this NPort will be acting as a TCP client.

Dial-in

The NPort listens for a TCP/IP connection request from the remote Ethernet modem or host. The NPort’s response depends on the ATS0 value, as outlined below.

ATS0=0 (default): The NPort will temporarily accept the TCP connection and then send the RING signal out through the serial port. The serial controller must reply with “ATA” within 2.5 seconds to accept the connection request, after which the NPort enters data mode. If no “ATA” command is received, the NPort will disconnect after sending three “RING” signals.

ATS0≥0:

The NPort will accept the TCP connection immediately and then send the CONNECT <baud> command to the serial port, in which <baud> represents the baudrate of the NPort’s serial port. After that, the NPort immediately enters data mode.

Dial-out

The NPort accepts the AT command ATD <IP>:<TCP port> from the serial port and then requests a TCP connection from the remote Ethernet Modem or PC. This is where <IP> is the IP address of the remote Ethernet modem or PC, and <TCP port> is the TCP port number of the remote Ethernet modem or PC. Once the remote unit accepts this TCP connection, the NPort will send out the CONNECT <baud> signal via the serial port and then enter data mode.

Disconnection Request from the Local Site

When the NPort is in data mode, the user can drive the DTR signal to OFF, or send +++ from the local serial port to the NPort. The NPort will enter command mode and return NO CARRIER via the serial port, and then input ATH to shut down the TCP connec tion after 1 second.

Disconnection Request from the Remote Site

After the TCP connection has been shut down by the remote Ethernet modem or PC, the NPort will send the NO CARRIER signal via the serial port and then return to command mode.

Configuration

The Administrator-Configuration window is divided into four parts.

• The top section contains the function list and online help area. (Windows NT does not support this .chm file format.)

• The five Administrator function g r oups are listed in the left section.

• A list of NPort serial device server s, each of which can be selected to process user requirements, is displayed in the right section.

• The activity Log, which displays messages that record the user’s processing history, is shown in the bottom section.

Broadcast Search

The Broadcast Search function is used to locate all NPort units that are connected to the same LAN as your computer. Since the Broadcast Search function searches by MAC address and not IP address, all NPort units connected to the LAN will be located, regardless of whether or not they are part of the same subnet as the host.

1. Position the cursor in the right middle section of the Administrator window and then click the right mouse button.

2. The Broadcast Search window will open and display the Model, IP Address, MAC Address, and Progress of the search for that particular devic e.

3. When the search is complete, the Broadcast Search window will close, and the NPort units that were located will be displayed in the right panel of the Administrator window. If you found more than one server connected to this network, refer to the MAC address sticker on your server(s) to determine which server(s) are the ones you wish to configure. To configure an NPort, place the cursor over the row displaying that NPort’s information, and then double click the left mouse button.

The meanings of the six “Status” states are given below (note that the te rm Fixed is borrowed from the standard fixed IP address networking terminology):

Lock

The NPort is password protected, “Broadcast Search” was used to locate it, and the password has not yet been entered from within the current Administrator session.

Unlock

The NPort is password protected, “B roadcast Search” was used to locate it, and the password has been entered from within the current Administrator session. Henceforth during this Administrator session, activating various utilities for this NPort will not require r e-entering the server password.

Blank

The NPort is not password protected, and “Broadcast Search” was used to locate it.

Fixed

The NPort is not password protected, and “Search by IP address” was used to locate it.

Lock Fixed

The NPort is password protected, “Specify by IP address” was used to locate it, and the password has not yet been entered from within the current Administrator session.

Unlock Fixed

The NPort is password protected, “Specify by IP address” was used to locate it, and the password has been entered from within the current Administrator session. Henceforth during this Administrator session, activating various utilities for this NPort will not require re-entering the server password.
