Overview

NE-4100 Series Network Enablers are serial-to-Ethernet embedded modules that come in 3 types: drop-in type (NE-4100T), RJ45 type (NE-4110S/A), and pin header type (NE-4120S/A). The letters at the end of the model numbers indicate the serial signal supported by the product. T represents TTL, whereas S and A represent RS-232 and RS-422/485, respectively.

NE-4100 Series products are very compact—less than half the size of a credit card. With such a small size, these Embedded Network Enablers fit into almost any kind of serial device to make the serial device 10/100M Ethernet ready. These products also come with a built-in TCP/IP stack for fast integration with your serial devices. This means that your engineers no longer need to spend a lot of time on TCP/IP programming, but instead can focus on developing other major features, shortening your product’s time to market. The reliable TCP/IP communication firmware that comes with NE-4100 Series products can be configured easily with a user-friendly Windows utility, Web browser, serial console, or telnet console. In addition, a Windows-based NECI (Network Enabler Configuration Interface) Library is available to help you develop your own Windows utilities.

An integration kit and a complete development kit containing a development board, documents, sample code, cables, and accessories are available for evaluation and development use.

Wiring Requirements

This section describes some important safety precautions that you should pay attention to before proceeding with any installation.

Safety First!

Be sure to disconnect the power cord before installing and/or wiring your evaluation boards for the NE-4100 Series modules.

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!

Please take care when handling the evaluation boards. When plugged in, the evaluation boards’ internal components generate heat, and consequently the board may feel hot to the touch.

You should also pay attention to the following points:

# 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 shares similar electrical characteristics can be bundled together.

# Keep input wiring and output wiring separate.

# Where necessary, it is strongly advised that you label wiring to all devices in the system.

Attaching NE-4100T to the Evaluation Board

Before connecting your NE-4100-ST to the power supply, network, and serial device, you first need to attach NE-4100T to the NE-4100-ST evaluation board. In the center of the evaluation boards, there is a square with one white inverted triangle (shown as black in the figure) on one of its sides, and 2 rows of female sockets on the other two sides. The NE-4100T board also has a white inverted triangle on one of its sides. When attaching your NE-4100T to NE-4100-ST, make sure these 2 white inverted triangles are facing the same direction, as shown in the following figure.

Connecting the Power

Connect the 12 VDC power line with the evaluation boards’ power jack. If the power is properly supplied, the “Power” LED will show a solid red color until the system is ready, at which time the “Ready” LED will show a solid green color.

Connecting to the Network

If you are using NE-4100T, connect one end of the Ethernet cable to the NE-4100-ST’s RJ45 Ethernet port, and the other end of the cable to the Ethernet network. If you are using NE-4110 Series, connect one end of the Ethernet cable to the NE-4110 Series board and the other end of the cable to the Ethernet network. If the cable is properly connected, the RJ45 connector will indicate a valid connection to the Ethernet in the following ways:

LAN

The green indicator LED in the upper right corner blinks when the cable is properly connected to a 100 Mbps Ethernet network, and data is being transmitted.

LAN

The yellow indicator LED in the upper left corner blinks when the cable is properly connected to a 10 Mbps Ethernet network, and data is being transmitted.

Connecting to a Serial Device

Connect the serial data cable between the evaluation boards (NE-4100-ST and NE-4110-ST) and the serial device.

DI/O Settings

NE-4100 Series Embedded Network Enablers support 4 digital I/Os. All 4 digital I/Os are GPIO (General Purpose I/O) that allow you to set to “digital output” or “digital input” mode by software. On the evaluation board, LEDs are used to simulate output loading whereas the DIP switch simulates an input device.

DI/O mode for physical wiring is selected by the DI/O mode jumper. For example, when the DI/O mode of DI/O1 is set to DI, the circuit of DI/O1 on the NE-4100 series module is connected to Digital Input DIP switch, digit 1. When the firmware of the NE-4100 series sets DI/O1 to digital input mode, you can check the DI/O1 status with the Windows utility or Web browser. When you change digit 1 of the switch, the changes appear on the Web browser.

Selecting the Interface

The various NE-4100 Series models support 2 different serial interfaces. NE-4110S and NE-4120S support the RS-232 interface, and NE-4110A and NE-4120A support the RS-422/485 interface. For this reason, we provide an interface selectable jumper on the NE-4110-ST and NE-4120-ST evaluation boards, which are used with NE-4110 and the NE-4120 Series, respectively.

For example, if you are using NE-4110S or NE-4120S modules, use the jumper to select the RS-232 interface, as shown below.

RS485

Note that jumper JP2 on the NE-4110A and NE-4120A modules are for RS-485 (2-wire) and RS-422 (4-wire) settings. Short JP2 on the NE-4110A/4120A modules to set the serial interface to RS-485 (2-wire) mode. Leave JP2 open to set the serial interface to RS-422 (4-wire) mode.

Chapter 4 Choosing the Proper Operation Mode

In this section, we describe the various NE-4100 Series 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 operating mode in this chapter, refer to subsequent chapters for detailed configuration parameter definitions.

Overview

NE-4100 Series Embedded Network Enablers act as a bridge to connect your serial devices to the Ethernet. The built-in TCP/IP stack saves you a lot of time on programming networking protocols. One simple step allows you to choose the proper operating mode, and then use your computer to access, manage, and configure your serial device 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 various kinds of instruments. Since NE-4100 Series Network Enablers are equipped with the ability to convert between serial and Ethernet signals, your SCADA and data collection system will be able to access all devices connected to a standard TCP/IP network, regardless of whether the devices are used locally or at a remote site.

Three different socket modes—TCP Server, TCP Client, and UDP Server/Client—and one real COM mode are available. The main difference between the TCP and UDP protocols is that TCP

guarantees delivery of data by requiring the recipient to send an acknowledgement to the sender. UDP does not require this type of verification, making it possible to offer speedier delivery. UDP also allows multicasting of data to groups of IP addresses.

NOTE

Pictures in this Chapter use NE-4110S as an example.

TCP Server Mode

In TCP Server mode, NE-4100 provides a unique IP:Port address on a TCP/IP network. NE-4100 Series boards wait passively to be contacted by the host computer, allowing the host computer to establish a connection with and get data from the serial device. 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.

As illustrated in the figure, data transmission proceeds as follows:

1. The host connects to the NE-4100 Series boards

configured for TCP Server Mode.

2. Once the connection is established, data can be

transmitted in both directions—from the host to the NE-4100 Series boards, and from the NE-4100 Series boards to the host.

NE-4100 Series User’s Manual Choosing the Proper Operation Mode

4-3

TCP Client Mode

In TCP Client mode, NE-4100 Series boards can actively establish a TCP connection to a pre-defined host computer when serial data arrives.

After the data has been transferred, NE-4100 Series boards can automatically disconnect from the host computer by using the TCP alive check time or Inactivity time settings. Refer to the following chapters for more details.

As illustrated in the figure, data transmission proceeds as follows:

1. The NE-4100 Series board running TCP

Client Mode actively establishes a connection based on the conditions set in the firmware. You can let the NE-4100 board connect to a remote host on start up, or connect later when data from serial device arrives.

2. Once the connection is established, data can

be transmitted in both directions—from the host to the NE-4100 board, and from the NE-4100 board to the host.

UDP Mode

Compared to TCP communication, UDP is faster and more efficient. In UDP mode, you can multicast data from the serial device to multiple host computers, and the serial device can also receive data from multiple host computers, making this mode ideal for message display applications.

NE-4100 Series User’s Manual Choosing the Proper Operation Mode

4-4

Real COM Mode

NE-4100 Series boards come equipped with COM drivers that work with Windows 95/98/ME/NT/2000/XP systems. The driver establishes a transparent connection between host and serial device by mapping the IP:Port of the NE-4100 Series boards’ serial port to a local COM port on the host computer.

The driver used for Real COM Mode comes with the NE-4100 Series Windows Administrator which is installed automatically on your computer when you install the NE-4100 Series Administration Suite.

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 NE-4100 Series boards accept the Ethernet frame, unpack the TCP/IP packet, and then transparently send it to the appropriate serial device attached to the NE-4100 Series boards’ serial port.

Real COM Mode allows several hosts to have access control of the same NE-4100 Series board. The Moxa driver that comes with your NE-4100 Series controls host access to attached serial devices by checking the host’s IP address.

Modify the Accessible IP Setting table when a public IP address is required for your application.

Chapter 5 Initial IP Address Configuration

When setting up your NE-4100 Series module for the first time, the first thing you should do is configure the IP address. This chapter introduces the methods that can be used to configure the NE-4100 Series module’s IP address. For more details about network settings, see the Network Settings section from Chapter 6, Web Console Configuration.

This chapter includes the following sections:

! Initializing NE-4100 Series Module’s IP Address

! Factory Default IP Address

! NE-4100 Series Administration Suite $ recommended configuration method

! ARP

! Telnet Console

! Serial Console (19200, n, 8, 1)

NE-4100 Series User’s Manual Initial IP Address Configuration

5-2

Initializing NE-4100 Series Module’s IP Address

1. Determine whether your NE-4100 Series module will use a Static IP or Dynamic IP (either

DHCP or BOOTP application).

2. If NE-4100 Series is used in a Static IP environment, you can use NE-4100 Series

Administration Suite, ARP, Web Console, Telnet Console, or Serial Console to configure the new IP address.

3. If NE-4100 Series is used in a Dynamic IP environment, you can use NE-4100 Series

Administration suite, Web Console, Telnet Console, or Serial Console to configure NE-4100 Series to get an IP address dynamically with DHCP, DHCP/BOOTP, or BOOTP.

Consult your network administrator on how to reserve a fixed IP address (for your NE-4100 module) in the MAC-IP mapping table when using a DHCP Server or BOOTP Server. In most applications, you should assign a fixed IP address to your NE-4100 module.

Factory Default IP Address

NE-4100 Series products are configured with the following default private IP address:

Default IP address: 192.168.127.254

(IP addresses of the form 192.168.xxx.xxx are referred to as private IP addresses, since it is not possible to directly access a device configured with a private IP address from a public network. For example, you would not be able to ping such a device from an outside Internet connection. NE-4100 Series applications that require sending data over a public network, such as the Internet, require setting up the server with a valid public IP address, which can be leased from a local ISP.)

NE-4100 Series Administration Suite

NE-4100 Series Administration Suite consists of some useful utilities that are used to configure and manage your NE-4100 Series embedded module.

See Chapter 7 for details on how to install NE-4100 Series Administration Suite, and how to use this suite of useful utilities to set up IP addresses and configure your NE-4100 Series embedded module.

ARP

You can use the ARP (Address Resolution Protocol) command to set up an IP address for your NE-4100 Series module. The ARP command tells your computer to associate the NE-4100 module’s MAC address with the intended IP address. You must then use Telnet to access the NE-4100 Series module, at which point the NE-4100 Series module’s IP address will be reconfigured.

In order to use this setup method, both your computer and NE-4100 Series module must be connected to the same LAN.

You may also use a cross-over Ethernet cable to connect the NE-4100 Series module directly to your computer’s Ethernet card.

Your NE-4100 Series module must be configured with the factory default IP address—

192.168.127.254—before executing the ARP command, as described below.

Take the following steps to use ARP to configure the IP address:

1. Obtain a valid IP address for your NE-4100 Series module from your network administrator.

2. Obtain the NE-4100 Series module’s MAC address from the label on the module.

3. Execute the ‘arp -s’ command from your computer’s MS-DOS prompt by typing:

NE-4100 Series User’s Manual Initial IP Address Configuration

5-3

arp –s 192.168.200.100 00-90-E8-xx-xx-xx

This is where 192.168.200.100 is the new IP address and 00-90-E8-xx-xx-xx is the MAC address for your NE-4100 Series. You will need to use both numbers, as described above in points 1 and

4. Next, execute a special Telnet command by typing:

telnet 192.168.200.100 6000 After issuing this command, a Connect failed message will appear, as shown here. After the NE-4100 module reboots, its IP address should be updated to the new address, and you can reconnect using Telnet, Web, or Administrator to check that the update was successful.

Telnet Console

Depending on how your computer and network are configured, you may find it convenient to use network access to set up your NE-4100 module’s IP address. This can be done using the Telnet program.

1. From the Windows desktop, click on Start and then select Run.

2. Type telnet 192.168.127.254 (use the

correct IP address if different from the default) in the Open text input box, and then click OK.

3. Type 2 to select Network settings, and then press Enter.

4. Type 1 to select IP address and then press Enter.

5. Use the Backspace key to erase the current IP address,

type in the new IP address, and then press Enter.

6. Press any key to continue.

7. Type m and then press Enter to return to the main

menu.

8. Type s and then press Enter to Save/Restart the

system.

9. Type y and then press Enter to save the new IP address

and restart the NE-4100 Series board.

Serial Console (19200, n, 8, 1)

You may use the RS-232 console port to configure the IP address for NE-4100 Series modules. We suggest using MOXA PComm Terminal Emulator, which is available free of charge as part of the MOXA PComm Lite program suite, to carry out the installation procedure, although other similar utilities may also be used. (Please go to www.moxa.com to download the installation program for PComm Lite.)

To begin with, use the serial cable to connect the NE-4100 module to your computer’s serial port.

1. Connect the RS-232 DEBUG (P1) serial port located on the evaluation board (NE-4100-ST,

NE-4110-ST, or NE-4120-ST) for NE-4100 module directly to your computer’s male RS-232 serial port.

2. From the Windows desktop click on Start % Programs % PComm Lite % Terminal

Emulator.

3. When the PComm Terminal Emulator window

opens, first click on the Port Manager menu item and select Open, or simply click on the Open icon.

4. The Property window opens automatically. From the

Communication Parameter page, select the appropriate COM port for the connection, COM1 in this example, and 19200 for Baud Rate, 8 for Data Bits, None for Parity, and 1 for Stop Bits.

5. From the Property window’s Terminal page, select

ANSI or VT100 for Terminal Type and then click OK.

If you select Dumb Terminal as the terminal type, some of the console functions—especially the “Monitor” function—may not work properly.

6. Type any character to switch automatically from data mode to console mode.

7. Start configuring the IP address under Networking

Settings. Refer to step 4, Telnet Console, for the rest of the IP settings.

Netmask

Setting Factory Default Necessity

E.g., 255.255.255.0 255.255.255.0 Required

A subnet mask represents all the network hosts at one geographic location, in one building, or on the same local area network. When a packet is sent out over the network, the NE-4100 module will use the subnet mask to check whether the desired TCP/IP host specified in the packet is on a local network segment. If the address is on the same network segment as the NE-4100 module, a connection is established directly from the NE-4100 Series module. Otherwise, the connection is established through the given default gateway.

Gateway

Setting Factory Default Necessity

E.g., 192.168.1.1 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. NE-4100 needs to know the IP address of the default gateway computer in order to communicate with the hosts outside the local network environment. For correct gateway IP address information, consult the network administrator.

(IP addresses of the form x.x.x.0 and x.x.x.255 are invalid.)

None Optional

When the user wants to visit a particular website, the computer asks a Domain Name System (DNS) server for the website’s correct IP address, and the computer uses the response to connect to the web server. DNS is the way that Internet domain names are identified and translated into IP addresses. A domain name is an alphanumeric name, such as moxa.com, that it is usually 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.

In order to use NE-4100’s DNS feature, you need to set the IP address of the DNS server to be able to access the host with the domain name. NE-4100 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.

NE-4100 plays the role of DNS client. NE-4100 Series functions that support domain name are

Time Sever IP Address, TCP Client-Destination IP Address, Mail Server, SNMP Trap IP Address, and IP Location Server.

Location

Setting Factory Default Necessity

1 to 39 characters

(E.g., Floor 1, office 2)

None Optional

Specify the location string for SNMP agents such as NE-4100 Series. This string is usually set to the street address where the NE-4100 is physically located.

IP Address Report

When NE-4100 Series products are used in a dynamic IP environment, users must spend more time with IP management tasks. For example, NE-4100 works as a server (TCP or UDP), and 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 server, the host must take care of what happens when the IP changes. NE-4100 Series products help out by periodically reporting their IP address to 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 NE-4100’s Auto IP report.

1. Use NE-4100 Series Administrator’s IP Address Report function.

2. Refer to Appendix C for the “Auto IP report protocol” to develop your own software.

Auto report to IP

TCP Server Mode

TCP alive check time

Setting Factory Default Necessity

0 to 99 min 7 min Optional

0 min: TCP connection is not closed due to an idle TCP connection. 1 to 99 min: NE-4100 automatically closes the TCP connection if there is no TCP activity for the given time. After the connection is closed, NE-4100 starts listening for another host’s TCP connection.

Inactivity time

Setting Factory Default Necessity

0 to 65535 ms 0 ms Optional

0 ms: TCP connection is not closed due to an idle serial line.

0-65535 ms: NE-4100 automatically closes the TCP connection if there is no serial data activity for the given time. After the connection is closed, NE-4100 starts listening for another host’s TCP connection.

This parameter defines the maintenance status as Closed or Listen on 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 value of inactivity time is set to 0, the current TCP connection is maintained until there is a connection close request. Although inactivity time is disabled, the NE-4100 will check the connection status between the NE-4100 and remote host by sending “keep alive” packets

NE-4100 Series User’s Manual Web Console Configuration

6-10

periodically. If the remote host does not respond to the packet, it assumes that the connection was closed down unintentionally. NE-4100 will then force the existing TCP connection to close.

The Inactivity time should at least be set larger than that of Force Transmit timeout. To prevent the unintended loss of data due a session getting disconnected, it is highly recommended that this value is set large enough so that the intended data transfer is completed.

Max connection

Setting Factory Default Necessity

1, 2, 3, 4 1 Required

Max connection is usually used when the user needs to receive data from different hosts simultaneously. The factory default only allows 1 connection at a time.

Max. connection 1:

NE-4100 series only allows 1 host to open the TCP connection to the specific serial port.

Max connection 2 to 4:

Allows requests from between 2 and 4 host’s TCP connection to open the specific NE-4100 series serial port, at the same time. When multiple hosts establish a TCP connection to the specific serial port at the same time, NE-4100 will duplicate the serial data and transmit to all of the hosts. Ethernet data is sent on a first-in-first-out basis to the serial port when data comes into NE-4100 from the Ethernet interface.

Delimiter 1

Setting Factory Default Necessity

00 to FF “0” for None Optional

Delimiter 2

Setting Factory Default Necessity

00 to FF “0” for None Optional

Once the NE-4100 receives both delimiters through its serial port, it immediately packs all data currently in its buffer and sends it out the NE-4100 series’ Ethernet port.

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 1K, the NE-4100 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 Factory Default Necessity

0 to 65535 ms 0 ms Optional

0: Disable the force transmit timeout.

1 to 65535: Forces the NE-4100’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 NE-4100 fetches the serial data from its internal buffer. If data is being received through the serial port, the NE-4100 stores the data in its internal buffer. NE-4100 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 as Force Transmit timeout.

Optimal force transmit timeout differs according to your application, but it must be at least as large as one character interval within the specified baud rate. For example, assume that the serial

NE-4100 Series User’s Manual Web Console Configuration

6-11

port is set to 1200 bps, 8 data bits, 1 stop bit, and no for parity. In this case, the total number of bits required to send a character is 10 bits and the time required to transfer one character is

( 10 bits / 1200 bits/s ) * 1000 = 8.3 ms.

Therefore, you should set Force Transmit timeout to be larger than 8.3 ms. Force Transmit timeout is specified in milliseconds and must be larger than 10 ms.

If the user wants to send a series of characters in a packet, the serial device attached to the NE-4100 should send characters without time delay larger than the Force Transmit timeout between characters, and the total length of data must be smaller than or equal to the NE-4100 module’s internal buffer size. NE-4100’s serial communication buffer size is 1 Kbyte per port.

Local TCP port

Setting Factory Default Necessity

1 to 65535 4001 Required

The TCP port that NE-4100 uses to listen to connections, and that other devices must use to contact NE-4100. To avoid conflicts with well known TCP ports, the default is set to 4001.

Command port

Setting Factory Default Necessity

1 to 65535 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 adjust the command port to another port if needed. The IP-Serial Lib will automatically check out the Command Port on NE-4100 so that the user does not need to configure the program.

Real COM Mode

TCP alive check time

Setting Factory Default Necessity

0 to 99 min 7 min Optional

0 min: TCP connection is not closed due to an idle TCP connection.

1 to 99 min: NE-4100 automatically closes the TCP connection if there is no TCP activity for the given time. After the connection is closed, NE-4100 starts listening for another Real COM driver’s connection from another host.

Max Connection

Setting Factory Default Necessity

1, 2, 3, 4 1 Required

Max connection is usually used when the user needs to receive data from different hosts simultaneously. The factory default only allows 1 connection at a same. When Max Connection is set to 1, the Real COM driver on the specific host has full control.

NE-4100 Series User’s Manual Web Console Configuration

6-12

Max. connection 1: Allows only 1 host’s Real COM driver to open the specific NE-4100 serial port.

Max connection 2 to 4: Allows 2 to 4 host’s Real COM drivers to open the specific NE-4100 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 tunnel 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 NE-4100 from the Ethernet interface.

When Max Connection is not 1, it also means that NE-4100 will be in “multi connection application.” In the “multi connection application,” when one of two to four hosts closes the COM port, NE-4100 will suspend receiving or sending serial data until the host successfully closes the COM port.

In multi connection applications, NE-4100 will use the serial communication parameters set in the console. If the host opens the COM with parameters different from NE-4100’s console setting, data communication may not work properly.

Delimiter 1

Setting Factory Default Necessity

00 to FF “0” for None Optional

Delimiter 2

Setting Factory Default Necessity

00 to FF “0” for None Optional

Once the NE-4100 receives both delimiters through its serial port, it immediately packs all data currently in its buffer and sends it out the NE-4100’s Ethernet port.

Force Transmit

Setting Factory Default Necessity

0 to 65535 ms 0 ms Optional

0: Disable the force transmit timeout.

1 to 65535: Forces the NE-4100’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 NE-4100 fetches the serial data from its internal buffer. If data is incoming through the serial port, NE-4100 stores the data in the internal buffer. NE-4100 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.

Optimal force transmit timeout differs according to 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 = 8.3 ms.

Therefore, you should set Force Transmit timeout to be larger than 8.3 ms. Force Transmit timeout is specified in milliseconds and must be larger than 10 ms.

NE-4100 Series User’s Manual Web Console Configuration

If the user wants to send the series of characters in a packet, the serial device attached to the NE-4100 should send characters without time delay larger than Force Transmit timeout between characters and the total length of data must be smaller than or equal to NE-4100’s internal buffer size. The serial communication buffer size of NE-4100 series is 1 Kbyte per port.

TCP Client Mode

TCP alive check time

Setting Factory Default Necessity

0 to 99 min 7 min Optional

0 min: TCP connection is not closed due to an idle TCP connection.

1 to 99 min: NE-4100 automatically closes the TCP connection if there is no TCP activity for the given time.

Inactivity time

Setting Factory Default Necessity

0 to 65535 ms 0 ms Optional

0 ms: TCP connection is not closed due to an idle serial line.

0-65535 ms: NE-4100 automatically closes the TCP connection, if there is no serial data activity for the given time.

If the value of inactivity time is set to 0, the current TCP connection is maintained until a connection close request is received. Although the inactivity time is disabled, the NE-4100 will check the connection status between the NE-4100 and remote host by sending “keep alive” packets periodically. If the remote host does not respond to the packets, it treats the connection as being down unintentionally. NE-4100 will then force the existing TCP connection to close.

The Inactivity time should at least be set larger than that of the 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 is completed.

NE-4100 has an IP address based filtering method to control access to the NE-4100.

Accessible IP Settings allows you to add or remove “Legal” remote host IP addresses to prevent unauthorized access. Access to NE-4100 is controlled by IP address. That is, if a host’s IP address is in the accessible IP table, then the host will be allowed access to the NE-4100. You can allow one of the following cases by setting the parameter.

# Only one host with a specific IP address can access the NE-4100

Enter “IP address/255.255.255.255” (e.g., “192.168.1.1/255.255.255.255”).

# Hosts on a given subnet can access the NE-4100

Enter “IP address/255.255.255.0” (e.g., “192.168.1.0/255.255.255.0”).

Event Type

Cold start

This refers to starting the system from power off (contrast this with warm start). When performing a cold start, NE-4100 will automatically issue an Auto warning message by e-mail, or send an SNMP trap after rebooting.

Warm start

This refers to restarting the computer without turning the power off. It’s the opposite of cold start. When performing a warm start, NE-4100 will automatically send an e-mail, or send an SNMP trap after rebooting.

Authentication failure

The user inputs a wrong password from the Console or Administrator. When authentication failure occurs, NE-4100 will immediately send an e-mail or send an SNMP trap.

IP address changed

The user has changed NE-4100’s IP address. When the IP address changes, NE-4100 will send an e-mail with the new IP address before NE-4100 reboots. If the NE-4100 fails to send mail to the mail server after 15 seconds, NE-4100 will reboot directly and abort the mail auto warning.

Password changed

The user has changed NE-4100’s password. When the password changes, NE-4100 will send an e-mail with the password change notice before NE-4100 reboots. If the NE-4100 fails to send mail to the mail server after 15 seconds, NE-4100 will reboot directly and abort the mail auto warning.

DCD changed

The DCD (Data Carrier Detect) signal has changed, also indicating that the modem connection status has changed. For example, a DCD change to high also means “Connected” between local modem and remote modem. If the DCD signal changes to low, it also means that the connection line is down.

When the DCD changes, NE-4100 will immediately send an e-mail or send an SNMP trap.

DSR changed

The DSR (Data Set Ready) signal has changed, also indicating that the data communication equipment’s power is off. For example, a DSR change to high also means that the DCE is powered ON. If the DSR signal changes to low, it also means that the DCE is powered off.

When the DSR changes, NE-4100 will immediately send an e-mail or send an SNMP trap.

COM Mapping

Network Enabler Administrator Suite comes with Windows 95/98/ME/NT/2000/XP Real COM drivers. After you install Network Enabler Administrator Suite, there are two ways to set up the NE-4100’s serial port as your host’s remote COM port.

The first way is On-line COM Mapping. On-line COM Mapping will check to make sure the NE-4100 is connected correctly to the network and then install the driver on the host computer.

The second way is Off-line COM Installation, with does not require connecting the NE-4100 to the network first. Off-line COM Mapping can decrease the system integrator’s effort by solving different field problems. With off-line installation, users can process the host software installation and then install the NE-4100 to different fields.

Use the following procedure to map COM ports:

1. On-line COM Mapping:

Connect NE-4100 to the network % Set NE-4100 to the proper IP address % Map COMs to your host % Apply Change.

2. Off-line COM Mapping:

Map COMs to your host % Apply Change % Connect NE-4100 to the network % Configure NE-4100’s IP address.

On-line COM Mapping

1. Broadcast Search for

NE-4100s on the network.

2. Select the COM Mapping

function group.

NE-4100 Series User’s Manual Web Console Configuration

7-17

3. Add the target that you

would like to map COM ports to.

4. The NE-4100 list that

appears is based on the Broadcast Search. Select the NE-4100 that you would like to map COM ports to.

5. Select COM Setting to

modify COM No., default setting, etc.

6. Select the COM No. Those “in use,”

“assigned” COM ports will also be indicated in this window.

If you select multiple serial ports or multiple NE-4100s, remember to check the “Auto Enumerating” function to use the COM No. you select as the first COM No.

NE-4100 Series User’s Manual Web Console Configuration

7-18

7. Hi-performance mode is the default for Tx mode. If the driver

completes sending data from the host to the NE-4100 Series, the driver will respond to the program with “Tx Empty.”

Under Classical mode, the driver will not notify the user’s program that a Tx has completed until all Tx data has been sent out from the NE-4100; this mode will case lower throughput. If you want to ensure that all data is sent out before further processing, classical mode is recommended.

Enable/Disable Tx/Rx FIFO. If disabled, NE-4100 will send one byte each time the Tx FIFO becomes empty, and an Rx interrupt will be generated for each incoming byte. This will cause a faster response and lower throughput. If you want to use XON/XOFF flow control, we recommend setting FIFO to Disable.

8. The Serial Parameter settings shown here are the default

settings when the NE-4100 is powered on. The program can define the serial parameter after the program opens the port via Win32API with the specific serial parameters.

9. After setting the COM Mapping, remember to select Apply

Change to save the information in the host system registry. The host computer will not be able to use the COM port until after selecting Apply Change.

10. Select Discard Change to tell Administrator to NOT save

the COM Mapping information to the host.

11. To save the configuration to a text file, select Export COM

Mapping. You will then be able to import this configuration file to another host and use the same COM Mapping settings in the other host.

NE-4100 Series User’s Manual Web Console Configuration

7-19

Off-line COM Mapping

1. Add a target by inputting the IP address and

selecting the Model Name without physically connecting the NE-4100 to the network.

2. Apply change.

Chapter 8 SW Reset Function

Network Enabler Administrator provides a “SW Reset Function” that allows the user to erase NE-4100’s password, or load factory defaults. To enable this function, open the NE’s

Configuration page, click on the Digital IO tab, and then check the Enable SW RESET Function (Use DIO 1) checkbox.

As indicated, the RESET command will be transmitted through GPIO1.

# SW Reset Pin: GPIO 1

# Reset is executed by pulling GPIO 1 low (normal is pulling high)

# Factory Default: Disable

% To erase the password, pull GPIO 1 low for a duration of 3 seconds.

% To load factory defaults, pull GPIO 1 low for a duration of 10 seconds.

Besides using Network Enabler Administrator to configure the SW Reset Function, you may also use the Network Enabler Web Console or Serial Console to carry out the configuration.

NE-4100 Series User’s Manual SW Reset Function

8-2

NOTE: The SW Reset function is disabled by default. If SW Reset is enabled, then since “disable” is the default, it will be reset to “disable” automatically after receiving a 10 sec. SW Reset command. This helps to prevent users from resetting to the default values inadvertently.

Appendix A Well Known Port Numbers

This appendix is included for your reference. Listed below are Well Known Port Numbers that may cause network problems if you configure NE-4100 for the same port. Refer to RFC 1700 for Well Know Port Numbers or refer to the following introduction from IANA.

The port numbers are divided into three ranges: the Well Known Ports, the Registered Ports, and the Dynamic and/or Private Ports.

The Well Known Ports are those from 0 through 1023.

The Registered Ports are those from 1024 through 49151.

The Dynamic and/or Private Ports are those from 49152 through 65535.

The Well Known Ports are assigned by IANA, and on most systems, can only be used by system processes or by programs executed by privileged users. The following table shows famous port numbers among the well-known port numbers. For more details, please visit the IANA website at http://www.iana.org/assignments/port-numbers.
