Chapter 1 Introduction
The NE-4100 Series embedded device server is a line of compact modules that act as network enablers. NE-4100 Series modules can be installed in or on a serial device to connect it to an Ethernet network, allowing you to gain network access to any electronic device that has a serial port. All NE-4100 Series modules come equipped with built-in TCP/IP protocols for fast integration, saving you time and energy on programming.
The following topics are covered in this chapter:

Overview
NE-4100 Series modules are a type of embedded device server or network enabler. An NE-4100 Series module may be installed in or attached to a serial device to make it accessible from a network. There are three types of module offered: drop-in (NE-4100T), RJ45 (NE-4110S, NE-4110A), and pin header (NE-4120S, NE-4120A). The last letter of the model number indicates the serial signal supported by the module. T indicates a TTL connector, S indicates an RS-232 connector, and A indicates an RS-422/485 connector. Each module includes 4 digital input/output channels, also known as DIO channels or GPIO channels.
NE-4100 Series modules are very compact—less than half the size of a credit card. At such a small size, they can be installed into almost any serial device. Each NE-4100 Series module also comes
with a built-in TCP/IP stack for fast integration. Engineers can spend less time on TCP/IP programming, and focus more on developing other major features, thereby shortening your product’s time to market. Modules may be easily configured 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 you r ow n Wi n do ws utilities.
Each module comes with a complete development kit containing an evaluation board, documents, sample code, cables, and accessories.

NE-4120S, NE-4120A, NE-4120-ST
The NE-4120S is an RS-232-to-Ethernet server, and the NE-4120A is an RS-422/485-to-Ethernet server. Both models use pin headers instead of RJ45 connectors. The NE-4120-ST is the evaluation board for testing NE-4120S and NE-4120A modules and developing your own applications.
ATTENTION
The NE-4120-ST is the same board as the NE-4110-ST but with an RJ45 jack and pin headers. If your evaluation board has “NE-4110-ST” printed on the board but has the RJ45 jack and pin headers, you have the NE-4120-ST board.

Wiring Precautions
This section describes some important safety precautions that you should pay attention to before proceeding with any installation.
ATTENTION
Be sure to disconnect the power cord before installing or wiring the evaluation board.
ATTENTION
Determine 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.
ATTENTION
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: y 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. Separate paths should be used to route wiring for power and devices. 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 wires sharing similar electrical characteristics may be bundled together.
y Keep input wiring and output wirin g se parate. y If power wiring and device wiring paths must cross paths, make sure the wires are
perpendicular at the intersection point.
y All wiring should be clearly labeled.

Selecting the Serial Interface
NE-4100 Series modules are available for different serial interfaces. The NE-4110S and NE-4120S are designed for the RS-232 interface, and the NE-4110A and NE-4120A are designed for the RS-422/485 interface. On the NE-4110-ST and NE-4120-ST evaluation boards, the Network Enabler Interface jumper block is used to select the serial interface used for your particular module.
JP2 Network Enabler Interface
For the NE-4110S and NE-4120S, the evaluation bo ard should be configured for the RS-232 interface, as shown below.

Connecting to the Network
To connect to the network for testing and development purposes, the module should be installed onto its evaluation board. Make sure that the module is correctly installed onto the evaluation board, then plug the Ethernet cable into the RJ45 jack. For models NE-4100T, NE-4120S, and NE-4120A, the RJ45 jack is located on the evaluation board; for models NE-4110S and NE-4110A, the RJ45 jack is located on the module itself.
If the cable is properly connected, the RJ45 connector will indicate a valid connection to the Ethernet as follows:

d
to a 100 Mbps Ethernet network, and data is being transmitted.
LAN
The yellow LED in the upper left corner blinks when the cable is properly connecte
d
to a 10 Mbps Ethernet network, and data is being transmitted.
When using a private IP address for the module, which is the factory default, make sure that netmask and IP settings are configured appropriately in order to access the module from a host on the network.
Connecting to a Serial Device
To connect to a serial device for testing and development purposes, the module should be installed onto its evaluation board. The module’s serial signals are routed to and from the RS-232 COM port on the evaluation board Use a serial data cable to connect the serial device to the COM port on the evaluation board.
Digital I/O Channel Settings
Each module provides 4 digital I/O (DIO) channels. All 4 DIO channels may be configured by software for either digital output or digital input mode. A DI channel is a channel that is operating in digital input mode; a DO channel is a channel that is operating in digital output mode. You may use the evaluation board’s Digital Output LEDs and Digital Input DIP switches as the digital input and output devices, or you may connect digital input/output devices to the DI/O Terminal Block.
ATTENTION
When using a digital input device connected to the DI/O Terminal Block, the correspond ing Digital Input DIP switch must be set to “OFF” or “High”. Setting the DIP switch to “ON” or “Low” will interfere with the signal from your digital input device.

DI/O Mode jumpers 0 through 3 correspond with DIO channels 0 through 3. The jumper’s position determines whether the corresponding channel is linked to a DIP switches or to an LED. When a channel’s jumper is set to the DI position, the channel’s input signal is controlled by the corresponding Digital Input DIP switch. When the jumper is set to the DO position, the channel’s output signal is routed to the corresponding Digital Output LED. For example, if DIO channel 0 is operating as a digital input channel, setting DI/O Mode

ATTENTION
The DI/O Mode jumpers are used to tell the evaluation board whether to use the Digital Output LEDs or the Digital Input DIP switches. The jumpers do not control the channel’s mode. Input and output mode is configured through the web, serial, or Telnet console, or through Network Enabler Administrator.
Digital Input
When using a Digital Input DIP switch as your input device, the “ON” position corresponds to “Low” status and the “OFF” position corresponds to “High” status. The result can be monitored with the Network Enabler Administrator or with the web console.

Chapter 4 Choosing the Proper Operation Mode
In this section, we describe the various operation modes of NE-410 0 Seri es modules. Depending on your intended use, the operation mode will determine how serial communication is handled by the network. There is an operation mode for COM port mapping from the host computer as well operation modes for TCP/IP protocols. After choosing the proper operating mode in this chapter, please refer to subsequent chapters for details on configuration parameters.
The following topics are covered in this chapter:
Overview TCP Server Mode TCP Client Mode UDP Mode Real COM Mode
http://www.RSPSupply.com/p-9766-Moxa-NE-4120A.aspx
NE-4100 Series User’s Manual Choosing the Proper Operation Mode
4-2
Overview
NE-4100 Series modules act as a bridge to connect your serial devices to the Ethernet. The built-in TCP/IP stack means less time spent on programming networking protocols. With one step you may choose the proper operation mode, then use your computer to access, manage, and configure your serial device from anywhere in the world over the Internet.
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 modules convert between serial and Ethernet signals, your SCADA and data collection system can be made accessible from every device 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—are available, as well as a Real COM mode. The main difference between the TCP and UDP protocol 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.
ATTENTION
The figures in this chapter use the NE-4110S as an example, but they apply to all models in the NE-4100 Series.
TCP Server Mode
TCP Server Mode
In TCP Server mode, the module is assigned a unique IP address and port number on the TCP/IP network. The module waits passively to be contacted by the host computer, allowing the host computer to establish a connection with and obtain 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 module configured for TCP
Server mode.
2. Once the connection is established, data can be
transmitted in both directions—from the host to the module, and from the module to the host.
http://www.RSPSupply.com/p-9766-Moxa-NE-4120A.aspx
NE-4100 Series User’s Manual Choosing the Proper Operation Mode
4-3
TCP Client Mode
TCP Client Mode
In TCP Client mode, the module can actively establish a TCP connection to a pre-defined host computer when serial data arrives.
After the data has been transferred, the module can automatically disconnect from the host computer by using the “TCP alive check time” or “Inactivity time” settings. Please refer to the following chapters for more details.
As illustrated in the figure, data transmission proceeds as follows:
1. The module actively establis hes a connection ba sed
on the conditions set in the firmware. You may let the module connect to a remote host on startup, 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 module, and from the module to the host .
UDP Mode
UDP Mode
UDP mode is faster and more efficient than TCP modes. 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.

Real COM Mode
Real COM Mode
Real COM mode allows users to continue using software that was written for pure serial communications applications. Each module comes equipped with COM drivers for Windo ws systems (95 and above). The serial module’s serial port is mapped by the driver to an IP address and port number. 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 module accepts the Ethernet frame, unpacks the TCP/IP packet, and then transparently sends the data to the attached serial device. The driver thus establishes a transparent connection between the host and serial device, allowing the host to treat the networked device as if it were directly attached.
ATTENTION
The Real COM driver comes with Network Enabler Administrator, which is part of the NE-4100 Series Administration Suite.
ATTENTION
Real COM mode can allow several hosts to have simultaneous access to the module. The driver controls host access to attached serial devices by checking the host’s IP address against the Accessible IP list.
Use the Accessible IP table to restrict access to the module 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 module’s IP address. For more details about network settings, please refer to the Network Settings section from Chapter 6.

Static vs. Dynamic IP Address
Determine whether the module will use a Static IP or Dynamic IP (either DHCP or BOOTP application).
y If the module is used in a Static IP environment, you will configure the IP address directly. y If the module is used in a Dynamic IP environment, you will configure the module to obtain an
IP address dynamically with DHCP, DHCP/BOOTP, or BOO TP.
ATTENTION
Consult your network administrator on how to reserve a fixed IP address for the module in the MAC-IP mapping table when using a DHCP Server or BOOTP Server. For most applications, you should assign a fixed IP address to the modu le.
Factory Default IP Address
The module is configured with the following default private IP address:
192.168.127.254
Please note that 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. 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
The NE-4100 Series Administration Suite consists of some useful utilities that are used to configure and manage the module. Please refer to Chapter 7 for details on using the NE-4100 Series Administration Suite to set up the module’s IP addresses.

You can use the ARP (Address Resolution Protocol) command to set up the module’s IP address. The ARP command tells your computer to associate the module’s MAC address with the intended IP address. You must then use Telnet to access the module, at which point the module’s IP address will be reconfigured.
ATTENTION
In order to use ARP, both your computer and the module must be connected to the same LAN. You may also use a cross-over Ethernet cable to connect the module directly to your computer’s Ethernet port.
Your module must be configured with the factory default IP address before executing the ARP command.

NE-4100 Series User’s Manual Initial IP Address Configuration
5-3
To configure the IP address using ARP, follow these instructions:
1. Obtain a valid IP address for the module from your network administrator.
2. Obtain the 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:
arp –s <new IF address> 00-90-E8-tt-tt-tt
For example,
arp –s 192.168.200.100 00-90-E8-00-00-00
In the example above, 192.168.200.100 is the new IP address and 00-90-E8-00-00-00 is the module’s MAC address, as obtained in steps 1 and 2.
4. Execute a special Telnet command by typing:
telnet <new IF address> 6000
For example,
telnet 192.168.200.100 6000
After issuing this command, a Connect failed message will appear, as shown here. After the module reboots, its IP address will be updated to the new address, and you can reconnect using Telnet, web, or Network Enabler Administrator to verify 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 module’s IP address. This can be done using the Telnet program, which requires that the module have a network connection and an IP address.
1. From the Windows desktop, click on Start and then select Run.
2. Telnet to the module’s current IP address. If this is the first time configuring the module, you
will telnet to the default IP address by typing
telnet 192.168.127.254
in the Open text box, then clicking OK.

Serial Console (19200, n, 8, 1)
If you wish to configure the IP address of the module without going through the network, you may use the serial console, which involves connecting a serial terminal directly to the RS-232 console port on the evaluation board. Moxa offers a free utility called PComm Terminal Emulator that can be used for this purpose, although you are free to choose among other terminal emulators that are widely available. PComm Lite may be downloaded at www.moxa.com.
Th
e following instructions show the procedure using PComm Lite. If you are using another utility,
the instructions may vary slightly.
1. Plug one end of a serial cable into the RS-232 DEBUG (P1) serial port on the evaluation
board; plug the other end directly into your computer’s male RS-232 serial port.
2. From the Windows desktop, click on Start Æ Programs Æ PComm Lite Æ Terminal
Emulator.
3. When the PComm Terminal Emulator window opens, select Open from the Port Manager
menu, or simply click on the Open icon.
4. The Property window opens automatically. On the Communication Parameter tab, select
the appropriate COM port for the connection, COM1 in this example. The parameters should be set to 19200 for Baud Rate, 8 for Data Bits, None for Parity, and 1 for Stop Bits.
5. On the Terminal tab, 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. Enter any character to switch automatically from data mode to console mode.

ATTENTION
If you forget the password, the ONLY way to configure the module is to “load factory defaults.” Remember to use Network Enabler Administrator to export the configuration file when you have
finished the configuration. After loading factory defaults, your configuration can be easily reloaded into the module. Please refer to Chapter 7 for more details about exporting and importing configuration settings.
Web Console Navigation
On the web console, the left panel is the navigation panel and contains an expandable menu tree for navigating among the various settings and categories. When you click on a menu item in the navigation panel, the main window will display the corresponding options for that item. Configuration changes can then be made in the main window. For example, if you click on Basic Settings in the navigation panel, the main window will show a page of basic settings that you can configure.
You must click on the Submit button to keep your configuration changes. The Submit button will be located at the bottom of every page that has configurable settings. If you navigate to another page without clicking the Submit button, your settings will not be retained.
Changes will not take effect until they are saved and the module is restarted! You may complete this in one step by clicking on Save/Restart after you submit a change. If you restart the module without saving your configuration, the module will discard all submitted changes.
Basic Settings
NOTE: “Serial Command Mode” is supported in firmware version 3.0 and above.

Click on the Modify button to open the Modify time settings window to input the correct local time.
Time server
Setting Factory Default Necessity
IP or domain address (E.g., 192.168.1.1, time.stdtime.gov.tw, or time.nist.gov)
Non
e Optional
NE-4100 Series modules use SNTP (RFC-1769) for auto time calibration. Enter the Time Server IP address or domain address. When the Time Se rve r I P add res s is pr ov ided ,
the module will request time information from the Time Server every 10 minutes.
Console
Web console, Telnet console
Setting Factory Default Necessity
Enable or Disable Enable Required
The web console and Telnet console can be disabled for security reasons. In some cases, you may want to disable one or both of these console utilities as an extra precaution to prevent unauthorized users from accessing the module. The factory default for both web console and Telnet console is Enable.
ATTENTION
If you disable both the web console and Telnet console, you can still use the serial console or Network Enabler Administrator to configure the module.

Network Settings
NOTE: “Serial Command Mode” is supported in firmware version 3.0 and above. You must assign a valid IP address to the module before it will work in your network environment.
Your network system administrator shoul d pr o vide you with an IP address and related settings for your network. The IP address must be unique within the network; otherwise the module will not have a valid connection to the network. First time users can refer to Chapter 5 - Initial IP Address Configuration for more information.
IP configuration
Method Function Definition
Static User defined IP address, Netmask, Gateway. DHCP
DHCP Server assigned IP address, Netmask, Gateway, DNS, and Time Server
DHCP/BOOTP
DHCP Server assigned IP address, Netmask, Gateway, DNS, and Time Server, or BOOTP Server assigned IP address
BOOTP BOOTP Server assigned IP address
IP configuration is a required field. The default setting is Static.
ATTENTION
In Dynamic IP environments, the module will attempt to obtain an IP address from the DHCP or BOOTP server 3 times at 30-second intervals. The timeout for the first try will be 1 second, the second try will be to 3 seconds, and the last try will be 5 seconds.
If the DHCP/BOOTP Server is unavailable, the module will use the default IP address (192.168.127.254), netmask, and gateway settings.

IP Address
Setting Factory Default Necessity
E.g., 192.168.1.1 (IP addresses of the form x.x.x.0 and x.x.x.255 are invalid.)
192.168.127.254 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 which is unique and valid in your network environment.
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 module will use the subnet mask to check whether the host specified in the packet is on a local network segment. If the address is on the same network segment as the module, a connection is established directly from the module. Otherwise, the connection is established through the default gateway.
Gateway
Setting Factory Default Necessity
E.g., 192.168.1.1 None Optional
A gateway acts as an entrance to another network. Usually, the computers that control traffic within the network or at the local Internet service provider are gat eway no des. The m odu l e 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 your network administrator.
DNS server 1 / DNS sever 2
Setting Factory Default Necessity
E.g., 192.168.1.1 (IP addresses of the form x.x.x.0 and x.x.x.255 are invalid.)
None Optional
Domain Name System (DNS) is how Internet domain names are identified and translated into IP addresses. A domain name is an alphanumeric name, such as moxa.com, that it is usually easier to rem
ember. A DNS server is a host that translates the text-based domain name into the corresponding numeric IP address which is used to establish a TCP/IP connection. When the user enters a website address, the computer asks a DNS server for the website’s IP address to connect to the web server.
When a DNS server is specified, the module acts as DNS client and will allow domain names instead of IP addresses to be used on the web console. The follo wi n g web console fields support the use of domain names: Time Sever IP Address, TCP Client-Destination IP Address, Mail Server, SNMP Trap IP Address, and IP Location Server. Two DNS servers may be specified, DNS server 1 and DNS server 2. DNS server 2 is included for use when DNS sever 1 is unavailable.

SNMP Settings
Community name
Setting Factory Default Necessity
1 to 39 characters (E.g., Support, 886-89191230 #300)
public Optional
A community name is a plain-text password mechanism that is used to weakly authenticate queries to agents of managed network devices.
Contact
Setting Factory Default Necessity
1 to 39 characters (E.g., Support, 886-89191230 #300)
None Optional
The SNMP contact information usually includes an emergency contact name and telephone or pager number.
Location
Setting Factory Default Necessity
1 to 39 characters (E.g., Floor 1, office 2) None Optional
Enter a location string for SNMP agents. This string is usually set to the street address where the module is physically located.
IP Address report
When the module is used in a dynamic IP environment, additional time must be spent on IP management tasks. For example, when a module is operating as a server (TCP or UDP modes), a PC operating as a client will need to know the module’s IP address. If the DHCP server assigns a new IP address to the module, the PC must have some way of obtaining the module’s new IP address. The IP Address report fields are used to set up periodic reporting of the module’s IP address when the module’s IP address is assigned by a server. The IP address report is sent automatically at regular intervals to an IP address and TCP port number of your choice. There are two ways view the module’s IP address report on a PC:
y Install Network Enabler Administrator and use the built-in IP Address Report function. y Develop software that parses the IP address report data. Please refer to Appendix C for details
on how to parse the module’s IP address report data.
Auto report to IP
Setting Factory Default Necessity
E.g., 192.168.1.1 or URL (IP addresses of the form x.x.x.0 and x.x.x.255 are invalid.)
None Optional
If left blank, auto IP reporting is disabled. If an IP address is entered along with a TCP port number, the IP address reports will be sent to the specified address and port number.
Auto report to TCP port
Setting Factory Default Necessity
E.g., 4001 4002 Optional
If left blank, auto IP reporting is disabled. If a TCP port number is entered along with an IP address, the IP address reports will be sent to the specified address and port number.

6-8
Auto report period
Setting Factory Default Necessity
Time interval (in seconds) 10 Optional
The Auto report period field specifies how often the module will report its IP address. An auto report period of 10 seconds means that an IP address report will be sent every 10 seconds.
ATTENTION
The module will send IP address reports only when assigned an IP address from a DHCP or BOOTP server. If a connection to a DHCP or BOOTP server is not available, no IP address report will be sent.
Serial Settings
NOTE: “Serial Command Mode” is supported in firmware version 3.0 and above.
Port Alias
Setting Factory Default Necessity
1 to 15 characters (E.g., PLC-No.1) None Optional
This function is designed for future use. You may enter a string to help in the module’s serial port from other serial ports.
Serial Parameters
ATTENTION
Refer to the serial communication parameters in your serial device’s user’s manual. The module’s serial parameters should be the same as the parameters used by your serial device.
Baud Rate
Setting Factory Default Necessity
50 bps to 115.2 Kbps for PCB V1.x 110 bps to 230.4 Kbps for PCB V2.x
115.2 Kbps Required
The module can be set for baud rates between 50 bps and 115.2 Kbps for PCB V1.x and between 110 bps to 230.4 Kbps for PCB V2.x.

5, 6, 7, 8 8 Required
When the user sets Data Bits to 5 bits, the Stop Bits setting will automatically change to 1.5 bits.
Stop Bits
Setting Factory Default Necessity
1, 2 1 Required
Stop Bits will be set to 1.5 when Data Bits is set to 5 bits.
Parity
Setting Factory Default Necessity
None, Even, Odd, Space, Mark None Required
Flow control
Setting Factory Default Necessity
None, RTS/CTS, DTR/DSR, XON/XOFF RTS/CTS Required
FIFO
Setting Factory Default Necessity

NE-4100 Series User’s Manual Web Console Configuration
6-10
TCP alive check time
Setting Factory Default Necessity
0 to 99 min 7 min Optional
0 min: The TCP connection is not closed due to an idle TCP connection. 1 to 99 min: The module automatically closes the TCP connection if there is no TCP activity for
the given time. After the connection is closed, the module starts listening for another host’s TCP connection.
Inactivity time
Setting Factory Default Necessity
0 to 65535 ms 0 ms Optional
0 ms: The TCP connection is not closed due to an idle serial line. 0-65535 ms: The module automatically closes the TCP connection if there is no serial data activity
for the given time. After the connection is closed, the module 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 Inactivity time is set to 0, the current TCP connection is maintained until there is a connection close request. Even with Inactivity time is disabled, the module will still check the connection status between itself and the remote host by sending “keep alive” packets periodically. If the remote host does not respond to the packet, it assumes that the connection was closed down unintentionally. The module will then force the existing TCP connection to close.
ATTENTION
The Inactivity time should be longer than the Force transmit timeout. To prevent the unintended loss of data due a session getting disconnected, it is strongly 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 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: The module will only allow 1 host to open the TCP connection to the specific serial port.
Max connection 2 to 4: The module will allow requests from between 2 and 4 host’s TCP connection to open the serial port at the same time. When multiple hosts establish a TCP connection to the serial port at the same time, the module 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 the module from the Ethernet interface.
Delimiter 1
Setting Factory Default Necessity
00 to FF “0” for None Optional
http://www.RSPSupply.com/p-9766-Moxa-NE-4120A.aspx
NE-4100 Series User’s Manual Web Console Configuration
6-11
Delimiter 2
Setting Factory Default Necessity
00 to FF “0” for None Optional
The Delimiter fields are used to specify a character or 2-character sequence which will act as a marker to control packing of serial data. By default, no delimiter characters are defined, so the module transmits data as soon as it is received. When a delimiter character or characters are defined, the module will hold data in its buffer until it receives the delimiter character or 2-character sequence. When the delimiter is received, the module will pack up the data in its buffer and send it through the Ethernet port.
Use Delimiter 1 to define the first delimiter character in hex. If only one delimiter character will be used, Delimiter 2 should be set to “0”. If the delimiter will be a two-character sequence, use Delimiter 2 to define the second character. To disable the use of delimiters, set both Delimiter 1 and Delimiter 2 to “0”.
Note that data packing is not only controlled by the delimiter; it is also influenced by the module’s buffer size and the Force transmit field. If the delimiter has not been received by the time the 1K buffer is full, the module will pack the data for network transmission and clear the buffer. Also, if the module will also pack data for network transmission if the next byte of data is not received within the Force transmit time.
ATTENTION
Do not enable Delimiter 2 if Delimiter 1 has been disabled. The delimiter function will not work properly if Delimiter 2 is enabled without Delimiter 1.
Force transmit
Setting Factory Default Necessity
0 to 65535 ms 0 ms Optional
0: The force transmit timeout is disabled. 1 to 65535: If the module does not receive the next byte of data within the time specified, it will
packed the data in its buffer into the same data frame for network transmission. The Force transmit field is typically used in conjunction with the Delimiter fields to specify how
data in the module’s buffer is packed for network transmission. When delimiters are used, the module accumulates data in its buffer as it waits to receive a delimiter. If there is a break in communication, data will be held in the buffer as the module continues to wait for a delimiter. The Force transmit field allows you to specify the maximum amount of time that the module will wait for data. With Force transmit enabled, the module will automatically pack the data in the buffer for network transmission if no data is received for the specified time.
When set to 0, Force transmit is disabled, which means there is no time limit for how long the module will wait to receive data. When set between 1 and 65535, the module will pack data as soon as there has been no serial communication for the specified time.
The optimal force transmit time depends on your application, but it should be larger than one character interval within the specified baud rate to have any effect. 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 one character is 10 bits, and the time required to transfer one character is
(10 bits / 1200 bits/s) × 1000 ms/s = 8.3 ms.
http://www.RSPSupply.com/p-9766-Moxa-NE-4120A.aspx
NE-4100 Series User’s Manual Web Console Configuration
6-12
Since it requires about 9 ms to send one character, the Force transmit should be 10 ms or more to have any effect. At 9 ms or less, the module will simply pack every character as it is received, which would be the same as if no delimiter characters or Force transmit time were specified at all.
Local TCP port
Setting Factory Default Necessity
1 to 65535 4001 Required
Use this field to indicate the TCP port that the module will use to listen to connections, and that other devices must use to contact the module. To avoid conflicts with well known TCP ports, the default is set to 4001.
Real COM Mode
NOTE: “Serial Command Mode” is supported in firmware version 3.0 and above.
TCP alive check time
Setting Factory Default Necessity
0 to 99 min 7 min Optional
0 min: The TCP connection is not closed due to an idle TCP connection. 1 to 99 min: The module automatically closes the TCP connection if there is no TCP activity for
the given time. After the connection is closed, the module starts listening for another host’s TCP connection.
Max connection
Setting Factory Default Necessity
1, 2, 3, 4 1 Required
Max connection is used when the user needs to receive data from different hosts simultaneously. The factory default only allows 1 connection at a time. When Max Connection is set to 1, the Real COM driver on the specific host has full control.
Max. connection 1: The module will only allow 1 host’s Real COM driver to open a connection to the module’s serial port.
Max connection 2 to 4: The module will allow requests from between 2 and 4 different hosts to open the module’s 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.
http://www.RSPSupply.com/p-9766-Moxa-NE-4120A.aspx
NE-4100 Series User’s Manual Web Console Configuration
6-13
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 module from the Ethernet interface.
ATTENTION
When Max connection is greater than 1, it means that the module will be used for multi-connection applications. In multi-connection applications, when one host closes the COM port, the module will suspend serial communication with all other hosts until that host successfully closes the COM port.
In multi-connection applications, the module will use the serial communication parameters set in the console. If the host opens the COM with parameters diffe rent from the module’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
The Delimiter fields are used to specify a character or 2-character sequence which will act as a marker to control packing of serial data. By default, no delimiter characters are defined, so the module transmits data as soon as it is received. When a delimiter character or characters are defined, the module will hold data in its buffer until it receives the delimiter character or 2-character sequence. When the delimiter is received, the module will pack up the data in its buffer and send it through the Ethernet port.
Use Delimiter 1 to define the first delimiter character in hex. If only one delimiter character will be used, Delimiter 2 should be set to “0”. If the delimiter will be a two-character sequence, use Delimiter 2 to define the second character. To disable the use of delimiters, set both Delimiter 1 and Delimiter 2 to “0”.
Note that data packing is not only controlled by the delimiter; it is also influenced by the module’s buffer size and the Force transmit field. If the delimiter has not been received by the time the 1K buffer is full, the module will pack the data for network transmission and clear the buffer. Also, if the module will also pack data for network transmission if the next byte of data is not received within the Force transmit time.
ATTENTION
Do not enable Delimiter 2 if Delimiter 1 has been disabled. The delimiter function will not work properly if Delimiter 2 is enabled without Delimiter 1.

Force transmit
Setting Factory Default Necessity
0 to 65535 ms 0 ms Optional
0: The force transmit timeout is disabled. 1 to 65535: If the module does not receive the next byte of data within the time specified, it will
packed the data in its buffer into the same data frame for network transmission. The Force transmit field is typically used in conjunction with the Delimiter fields to specify how
data in the module’s buffer is packed for network transmission. When delimiters are used, the module accumulates data in its buffer as it waits to receive a delimiter. If there is a break in communication, data will be held in the buffer as the module continues to wait for a delimiter. The Force transmit field allows you to specify the maximum amount of time that the module will wait for data. With Force transmit enabled, the module will automatically pack the data in the buffer for network transmission if no data is received for the specified time.
When set to 0, Force transmit is disabled, which means there is no time limit for how long the module will wait to receive data. When set between 1 and 65535, the module will pack data as soon as there has been no serial communication for the specified time.
The optimal force transmit time depends on your application, but it should be larger than one character interval within the specified baud rate to have any effect. 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 one character is 10 bits, and the time required to transfer one character is
(10 bits / 1200 bits/s) × 1000 ms/s = 8.3 ms. Since it requires about 9 ms to send one character, the Force transmit should be 10 ms or more to
have any effect. At 9 ms or less, the module will simply pack every character as it is received, which would be the same as if no delimiter characters or Force transmit time were specified at all.

TCP alive check time
Setting Factory Default Necessity
0 to 99 min 7 min Optional
0 min: The TCP connection is not closed due to an idle TCP connection. 1 to 99 min: The module automatically closes the TCP connection if there is no TCP activity for
the given time. After the connection is closed, the module starts listening for another host’s TCP connection.
Inactivity time
Setting Factory Default Necessity
0 to 65535 ms 0 ms Optional
0 ms: The TCP connection is not closed due to an idle serial line. 0-65535 ms: The module automatically closes the TCP connection if there is no serial data activity
for the given time. After the connection is closed, the module 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 Inactivity time is set to 0, the current TCP connection is maintained until there is a connection close request. Even with Inactivity time is disabled, the module will still check the connection status between itself and the remote host by sending “keep alive” packets periodically. If the remote host does not respond to the packet, it assumes that the connection was closed down unintentionally. The module will then force the existing TCP connection to close.
ATTENTION
The Inactivity time should be longer than the Force transmit timeout. To prevent the unintended loss of data due a session getting disconnected, it is strongly recommended that this value is set large enough so that the intended data transfer is completed.
ATTENTION
Inactivity time is only active when TCP connect on is set to Any Character.

network, and configuration events. Depending on the event, different options for automatic notification are available, as shown above. Mail refers to sending an e-mail to a specified address. Trap refers to sending an SNMP trap. The following items are events that can trigger an automatic warning.
Cold start
The module is started from a power off state. If this is selected, automatic notification is sent if the module is powered off and then powered on again.
Warm start
The module is restarted without turning the power off. If this is selected, automatic notification is sent if the module is rebooted while still powered on.
Authentication failure
The user inputs a wrong password from the console or Network Enabler Administrator. If this is selected, automatic notification is sent if a user attempts to unlock the module and enters the wrong password.
IP address changed
The module’s IP address has been changed. If this is selected, the module will attempt to send an e-mail before it reboots with a new IP address. If the module fails to reach the mail server after 15 seconds, it will reboot anyways and no notification will be sent.
Password changed

DCD changed, DSR changed
DCD (Data Carrier Detect) and DSR (Data Set Ready) signals indicate serial communication status. Administrators can receive e-mail and SNMP trap warnings when there is a status change to the serial port. 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. A DSR change to high means that the Data Circuit-Terminating Equipment (DCE) is powered ON. If the DSR signal changes to low, it also means that the DCE is powered off.
ATTENTION
DCD changed and DSR changed events are not available for RS-422 or RS-485 modules, because those standards do not use DCD and DSR signals.
Digital IO
DIO Settings
NOTE: “Serial Command Mode” is supported in firmware version 3.0 and above. The DIO Settings page is where each DIO channel is configured. Use Mode to specify either
digital input or digital output operation. IN is for digital input operation, where the channel’s status is controlled by an external digital switch. OUT is for digital output operation, where the channel transmits a high or low signal. Use Status to control high or low status for digital output channels; Status setting will be ignored for digital input channels.
TCP Port is the port number that will be reserved for DIO commands. DIO commands may be used to control and obtain data from the module’s DIO channels. Please refer to Appendix D for additional information on DIO commands.
SW Reset Function (Use DIO 1) is used to enable or disable the use of DIO 1 as a reset button. When SW Reset is enabled, DIO 1 will be forced to digital input mode and will act as a reset button. Pulling DIO 1 “low” for 3 seconds will erase the password, and pulling DIO 1 “low” for 10 seconds will load the factory defaults. This function is disabled by default.

Configuration Functions
Configuration functions are where module parameters may be viewed and changed. All parameters available in the web console are also available here. In addition, a module’s configuration may be imported or exported and the firmware may be updated. Note that the module list must be manually updated every time Configuration functions are accessed.
ATTENTION
Every time Configuration functions need to be used, you must first use Broadcast Search or Specify by IP Address to add the module to the Configuration module list. The Configuration
module list is not retained when other functions are used.
ATTENTION
When Network Enabler Administrator is first opened, you must use Broadcast Search or Specify by IP Address to find the module in order to unlock other functions.
Broadcast Search
Broadcast Search is used to find all NE-4100 Series modules that are connected to the same LAN as your computer. Since the Broadcast Search function searches by MAC address and not IP address, all NE-4100 Series modules connected to the LAN will be located, regardless of whether or not they are part of the same subnet as the host. If you have trouble detecting the module, please verify your network settings and connection.
1. Select Broadcast Search from the Configuration context menu. Note that this menu may
also be opened by right-clicking Configuration in the navigation panel.

2. A Searching window will open, showing that the program is searching for NE-4100 Series
modules connected to this network. You may click Stop as soon as the desired module is found.
3. After the search is finished, all modules that were found will be shown in the Configuration
module list. Select the desired module to begin using other functions with it. If you locate more than one module connected to this network, use the MAC address to determine which module you wish to configure.
Specify by IP Address
Specify by IP Address is used to search the network for a specific module by its IP address. When the module is found, it is added to the Configuration module list and may be selected for use with other functions. If you have troubl e det ect i ng t he module, please verify your network settings and connection.
Locate
Locate sends a signal to make the selected module’s “Ready” LED blink, which makes it easier to locate the module if you are managing multiple modules at the same time. The module does not have a built-in LED, but the evaluation board maps the signal to its own onboard LED. Please refer to Pin Assignments in Chapter 2 for information on which pin is associated with the “Ready” LED. Click Stop to turn off the Locate function.

NE-4100 Series User’s Manual Network Enabler Administrator
7-17
In addition, individual COM ports in the module list may be selected or deselected for monitoring.
COM Mapping Functions
Network Enabler Administrator is installed with Real COM drivers that work with Windows 95 and above. These drivers map a COM port on the host PC to the module, so an application communicating with COM5, for example, could transparently be connected to the module. COM po
rts may be mapped before the module is connected. It is also possible to map sequential COM
ports to different modules at the same time. COM Mapping functions are used to configure, enable, and disable the module’s Real COM
drivers. After the COM mappings have been configured and enabled, Network Enabler Administrator is not needed for the COM mappings to remaining effect. If the PC is rebooted, the COM mappings will still be in effect after booting up.
Add and Remove Target
Add Target searches for modules over the network to add to the COM Mapping module list. Remove Target deletes the selected items from the COM Mapping COM port list. Please refer to the Monitor section earlier in this chapter for additional details on Add Target and Remove Target.
COM Settings
COM Settings is used to assign the local COM port number to the selected module, adjust the module’s serial settings, and adjust some advanced settings. Select COM Settings in the COM
Mapping context menu. Note that this menu may also be opened by right-clicking COM Mapping in the navigation panel or by right-clicking the desired module in the module list.
Multiple modules may be selected for configuration at the same time. Remember to use Apply Change to save your changes, or Discard Change to undo the changes. To activate the mappings, use Enable.

Basic Settings
In the Basic Settings tab, you may map a local COM port number to the selected module.
Make sure that Auto Enumerating COM Number for Selected Ports is checked when using mapping to multiple modules. When checked, this option automatically assigns available COM numbers sequentially. If not checked, each module will have to be manually assigned a COM port number.
Advanced Settings
In the Advanced Settings tab, you may configure how serial data is transmitted over the network.
http://www.RSPSupply.com/p-9766-Moxa-NE-4120A.aspx
NE-4100 Series User’s Manual Network Enabler Administrator
7-19
When Tx Mode is set to Hi-Performance, the Real COM driver sends a “Tx Empty” signal to the host as soon as it sends serial data over the network to the selected module. In Hi-performance mode, the driver will not verify that the module has successfully received and passed the data to the serial device. When Tx Mode is set to Classical, the driver sends the “Tx Empty” signal only after the module has confirmed that serial data has been successfully passed on to the serial device. The additional step of verification, plus the fact that it must be transmitted over the network, means that Classical mode will cause lower throughput. If you want to ensure that all data is sent out before further processing, Classical mode is recommended.
When FIFO is disabled, the selected module 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 time but lower throughput. If you want to use XON/XOFF flow control, we recommend setting FIFO to Disable.
Fast Flush is designed to improve response time for applications that use the Win32 “PurgeComm()” function. When Fast Flush is enabled, the Real COM driver automatically flushes the buffer when it receives the “PurgeComm()” function call. When disabled, applications that use the Win32 “PurgeComm()” function may perform markedly slower, because the Real COM driver will repeatedly query the module to make sure no data is queued in the buffer instead of just flushing the buffer. The repeated queries can cause a performance hit due to the additional time spent communicating over the network, typically about several hundred milliseconds when compared to local COM ports (physically on the PC). If your application uses PurgeComm() and performance seems sluggish, try enabling Fast Flush.
Serial Parameters
In the Serial Parameters tab, you may configure the selected module’s baud rate, parity, data bits, stop bits, and flow control. The parameters shown below are the default settings.
Enable and Disable
Enable and Disable are used to activate or deactivate the selected module’s COM mapping settings. Note that this menu may also be opened by right-clicking COM Mapping in the navigation panel or by right-clicking the desired module. COM port mappings may be individually enabl
ed or disabled.
Once a module’s COM mappings have been enabled, the Real COM driver will operate independently of Network Enabler Administrator. The mappings will be active whether or not Network Enabler Administrator is open.

Apply and Discard Change
Apply Change and Discard Change are used to save or delete any changes COM mapping settings. Select Apply Change in the COM Mapping context menu to save any changes made to the COM mappings; select Discard Change to undo any changes that were made to the COM mappings. Note that this menu may also be opened by right-clicking COM Mapping in the navigation panel or by right-clicking the desired module.
Import and Export COM Mapping
Import COM Mapping and Export COM Mapping are used to save and load the COM mappings for the Select Import COM Mapping in the COM Mapping context menu to load settings into the selected module from an exported file; select Export COM mapping to save the current settings for the selected module to a text file. Note that this menu may also be opened by right-clicking COM Mapping in the navigation panel or by right-clicking the desired module.
IP Address Report Functions
IP Address Report functions are used to view IP address reports from appropriately configured modules. When monitoring is activated, Network Enabler Administrator listens for IP address reports on a UDP port number, which may be configured under Settings in the IP Address Report context menu. Any IP address reports received at this port number will be displayed in the window.
Select Go to begin monitoring for IP address reports, Stop to cease monitoring, and Clear to clear the current display of reports.
Note that in order for a PC running Network Enabler Administrator to receive IP address reports from a module, the module must set the PC’s IP address as the destination. In addition, the module and the PC’s designated port number for IP address reports should match. Please refer to the Network Settings section in Chapter 6 for additional information on configuring a module to send IP address reports.

Linux Real TTY Drivers
Basic Procedures
The basic procedures to map a Linux host’s tty port to the module’s serial port are as follows:
1. Set up the module. After verifying that the IP configuration works and you can access the
module (by using ping, telnet, etc.), configure the module’s serial port to Real COM mode.
2. Install the Linux Real tty driver files on the host
3. 3. Map the module’s serial port to the host’s tty port
Hardware Setup
Before proceeding with the software installation, make sure you have completed the hardware installation. Note that the module’s default IP address is 192.168.127.254.
ATTENTION
After installing the hardware, be sure that the module’s serial port is configured to Real COM mode. This can be done with the web console, Telnet console, serial console, or Network Enabler Administrator.
Installing Linux Real TTY Driver Files
The instructions for installing the Linux Real TTY drivers are as follows:
1. Obtain the driver file from the included CD-RO M or from http://www.moxa.com
.
2. Log in to the console as a super user (root).
3. Execute cd / to go to the root directory.
4. Copy the driver file npreal2xx.tgz to the / directory.
5. Execute tar xvfz npreal2xx.tgz to extract all files into the system.
6. Execute /tmp/moxa/mxinst.
For Red Hat AS/ES/WS and Fedora Core1, append an extra argument as follows:
# /tmp/moxa/mxinst SP1
7. The shell script will install the driver files automatically. After the files are installed, you
will be able to see several files in the /usr/lib/npreal2/driver folder: > mxaddsvr (Add Server, mapping tty port)
> mxdelsvr (Delete Server, un-mapping tty port) > mxloadsvr (Reload Server) > mxmknod (Create device node/tty port) > mxrmnod (Remove device node/tty port) > mxuninst (Remove tty port and driver files)
At this point, you will be ready to map the system’s tty port to the module’s serial port.

NE-4100 Series User’s Manual Linux and UNIX Configuration
8-3
Mapping TTY Ports
Make sure that you set the operation mode of the module’s serial port to Real COM mode. After logging in as a super user, enter the directory /usr/lib/npreal2/driver and then execute mxaddsvr to map the module’s serial port to the host tty ports. The syntax of mxaddsvr is as follows:
mxaddsvr [Module’s IP Address] [Total Ports] ([Data port] [Cmd port]) The mxaddsvr command performs the following actions:
1. Modifies npreal2d.cf.
2. Cr
eates tty ports in directory /dev with major & minor number configured in npreal2d.cf.
3. Restarts
the driver.
Mapping tty ports automatically
To map tty ports automatically, you may execute mxaddsvr with just the IP address and number of ports, as in the following example:
# cd /usr/lib/npreal2/driver # ./mxaddsvr 192.168.3.4 16
In this example, 16 tty ports will be added, all with IP 192.168.3.4, with data ports from 950 to 965and command ports from 966 to 981.
Mapping tty ports manually
To map tty ports manually, you may execute mxaddsvr and manually specify the data and command ports, as in the following example:
# cd /usr/lib/npreal2/driver # ./mxaddsvr 192.168.3.4 16 4001 966
In this example, 16 tty ports will be added, all with IP 192.168.3.4, with data ports from 4001 to 4016 and command ports from 966 to 981.
Removing Mapped TTY Ports
After logging in as root, enter the directory /usr/lib/npreal2/driver and then execute mxdelsvr to delete a server. The syntax of mxdelsvr is:
mxdelsvr [IP Address]
Example:
# cd /usr/lib/npreal2/driver # ./mxdelsvr 192.168.3.4
The following actions are performed when executing mxdelsvr:
1. Modify npreal2d.cf.
2. Rem
ove the relevant tty ports in directory /dev.
3. Restar t t h e d r iv er. If the IP address is not provided in the command line, the program will list the installed servers
and total ports on the screen. You will need to choose a server from the list for deletion.

NE-4100 Series User’s Manual Linux and UNIX Configuration
8-4
Removing Linux Driver Files
A utility is included that will remove all driver files, mapped tty ports, and unload the driver. To do this, you only need to enter the directory /usr/lib/npreal2/driver, and then execute mxuninst to uninstall the driver. This program will perform the following actions:
1. Unload the driver.
2. Delete all files and directories in /usr/lib/npreal2
3. Delete directory /usr/lib/npreal2
4. Modify the system initializing script file.
UNIX Fixed TTY Driver
Installing the UNIX Driver
The instructions for installing the UNIX driver are as follows:
1. Log in to UNIX and create a directory for the Moxa TTY. To create a directory named
/usr/etc, execute the command:
# mkdir –p /usr/etc
2. Copy moxattyd.tar to th e dire ct or y you cr eate d. If yo u cr eate d th e /usr/etc directory above,
you would execute the following co mman d s:
# cp moxattyd.tar /usr/etc # cd /usr/etc
3. Extract the source files from the tar file by executing the command: # tar xvf moxattyd.tar
The following files will be extracted:
README.TXT moxattyd.c --- source code moxattyd.cf
--- an empty configuration file
Makefile --- makefile VERSION.TXT --- fixed tty driver version FAQ.TXT
4. Compile and Link
For SCO UNIX: # make sco For UnixWare 7:
# make svr5

Configuring the UNIX Driver
Modify the configuration
The configuration used by the moxattyd program is defined in the text file moxattyd.cf, wh
ich is
in the same directory that contains the program moxattyd. You may use vi, or any text editor to modify the file, as follows:
ttyp1 192.168.1.1 950
For more configuration information, view the file moxattyd.cf, wh
ich contains detailed
descriptions of the various configuration parameters.
ATTENTION
The Device Name depends on the OS. See the Device Naming Rule section in README.TXT for more information.
To start the moxattyd daemon after system bootup, add an entry into /etc/inittab, with the tty name you configured in moxattyd.cf, as
in the following example:
ts:2:respawn:/usr/etc/moxattyd/moxattyd –t 1
Device naming rule
For UnixWare 7, UnixWare 2.1.x, and SVR4.2, use: pts/[n] For all other UNIX operating systems, use: ttyp[n]
Starting moxattyd
Execute the command init q or reboot your UNIX operating system.
Adding an additional server
1. Modify the text file moxattyd.cf t
o add an additional server. User may use vi or any text
editor to modify the file. For more configuration information, look at the file moxattyd.cf, wh
ich contains detailed descriptions of the various configuration parameters.
2. Find the process ID (PID) of the program moxattyd.
# ps -ef I grep moxattyd
3. Update the configuration of moxattyd program.
# kill -USR1 [PID] (e.g., if moxattyd PID = 404, kill -USR1 404)
This completes the process of adding an additional server

Overview
Serial command mode allows the module’s parameters to be retrieved or configured through the serial port, rather than through the console port or over the network. This is do ne through the use of specially parsed commands sent to the module through the serial port. Device manufacturers can take advantage of serial command mode to add local configuration capability to their products. For example, card reader manufacturers can use the card reader’s number pad to configure serial and network settings such as IP address, netmask, and baud rate. Serial command mode thus allows on-site configuration of devices without requiring a laptop or other additional equipment.
Serial command mode is built into firmware version 3.0 and above.
Serial Command Format and Command Set
Each command and reply is a sequence of case-sensitive ASCII characters transmitted in the following order: Head, Command Code, OP Code, Parameter, and Tail.
ATTENTION
The carriage return character is used as the last byte or Tail for each data frame; an additional line feed character is not required. For most systems, the Enter key typically sends a carriage
return character and a line feed character. CR is used to refer to the carriage return character in most terminal emulators and in this manual, LF is used to refer to the line feed character. In hex, CR is 0x0D and LF is 0x0A. In C language, “\r” refers to CR, whereas “\n” refers to CR + LF.
Command Structure
Descriptor Bytes Character Description
C-Head 1 “>” fixed value (0x3E)
Command Code 1 “R”, “W”
R: get module parameter W: set module parameter
OP Code 2 (varies)

Configuring Trigger Type
Serial command mode may be triggered by either software or hardware. Initially, you may use one of the following configuration tools to set the trigger type: Network Enabler Administrator, Telnet console, web console, or serial console.
The hardware trigger involves using DIO 0 to enter serial command mode. The software trigger involves using a three-character sequence sent to the serial port to enter serial command mode. For hardware versions 1.1 or earlier, when the SW Trigger is enabled, the highest achievable data transmission rate will be reduced from 234000 bps to 55000 bps. This is because all data received through serial port 0 will be parsed. In other words, the system must continuously check the serial port data for the SW Trigger characters. This is not an issue for hardware versions 2.1 and later.
Network Enabler Administrator
To use Network Enabler Administrator to configure the trigger type, you will need to find the module and open its configuration window. Please refer to Chapter 7 for additional details.
The trigger type will be configured under the Serial CMD tab. Check the Modify box in order to make changes to the settings. Enable must be checked in order to configure the trigger type.
Select H/W Control Pin (Use DIO 0) to trigger serial command mode through digital I/O channel 0.

When the trigger has been configured, click OK to save and restart the module with the new settings.
ATTENTION
The default setting is HW Trigger Enabled. Only one type of trigger may be selected; hardware and software trigger may not be used at the same time.
Select Activated by Character to trigger serial command mode through the serial port. In this case, you will also need to enter the three characters (in HEX code) that will be used as the trigger characters.
