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
WE-2100T module.
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:
z 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.
z 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.
z Keep input wiring and output wiring separate.
z Where necessary, it is strongly advised that you label wiring to all devices in the system.
Attaching WE-2100T to the Evaluation Board
Before connecting your WE-2100T-ST to the power supply, network, and serial device, you first
need to attach WE-2100T to the WE-2100T-ST evaluation board. In the center of the evaluation
boards, there is a square with 2 rows of male pins on one of its sides. The WE-2100T board also
has 2 rows of female sockets on its bottom. When attaching your WE-2100T to WE-2100T-ST,
make sure the pins and the socket match with each other, as shown in the following figure.

Circuit Pad for External Connection
The circuit pad located on the left side of the evaluation boards is used to develop additional
application circuits. The circuit pad is circled in red in the figure below. As shown in the second
figure, the bottom row of the circuit pad is for connecting a 5V power supply, whereas the upper
row is for connecting a 3.3V power supply. There are totally 9 digital I/O pins on the right side.
The top row of the circuit pad is for grounding.

Connecting the Power
Connect the 12 VDC power line with the evaluation boards’ power jack.
Connecting to the Network
In the development stage, you may want to configure the WE-2100T with Ethernet since the
wireless LAN may not work before properly configured. If you are using WE-2100T, connect one
end of the Ethernet cable to the WE-2100T-ST’s RJ45 Ethernet port, 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 and the serial device. The “Console
Port” or “P1” is used as serial console interface and the “Data Port” or “P2” is used as data
interface.
DI/O Settings
WE-2100T supports up to 9 digital I/Os. All 9 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.
DIO mode for physical wiring is selected by the DIO mode jumper. For example, when the DIO
mode of DIO1 is set to DI, the circuit of DIO1 on the WE-2100T is connected to Digital Input
DIP switch, digit 1. When the firmware of the WE-2100T sets DIO1 to digital input mode, you
can check the DIO1 status with the Windows utility or Web browser. When you change digit 1 of
the switch, the changes appear on the Web browser.

1. First, use the DIO selectable jumpers to set the D/O modes, as shown below.
2. After the DIO modes are set, use the Digital Input DIP Switches to configure the status for
DI0 – DI3. You can either configure the status to “Low” or “High.” If you wish to configure
DI0’s status to “Low” and the others to “High,” set DIP Switch 1 to the “ON” position and
the others to the “OFF” position, as shown below.
3. DO4 – DO8’s status must be configured with the Web Console. If you configure DO4’status
to “Low” and the others to “High,” the DO4’s LED will show solid green, and the other
LEDs will not light up. Refer to chapter 6 for more configuration details.

Chapter 4 Choosing the Proper Operation Mode
In this section, we describe the various WE-2100T 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.

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

Overview
WE-2100T Series Embedded Wireless Network Enablers act as a bridge to connect your serial
devices to the wireless LAN. 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 WE-2100T is 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—, one real COM
and RFC-2217 modes 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.
TCP Server Mode
In TCP Server mode, WE-2100T provides a unique
IP:Port address on a TCP/IP network. WE-2100T 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 8 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 WE-2100T configured for
TCP Server Mode.
2. Once the connection is established, data can be
transmitted in both directions—from the host to the
WE-2100, and from the WE-4100T to the host.
![](/img.php?id=819430&img=bg15.png)
NE-4100 Series User’s Manual Choosing the Proper Operation Mode
4-3
TCP Client Mode
In TCP Client mode, WE-2100T can actively
establish a TCP connection to a set of (max. 4)
pre-defined host computer when serial data
arrives.
After the data has been transferred, WE-2100T
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 WE-2100T running TCP Client Mode
actively establishes a connection based on
the conditions set in the firmware. You can
let the WE-2100T 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 WE-2100T, and from the
WE-2100T 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
WE-2100T comes equipped with COM
drivers that work with Windows
95/98/ME/NT/2000/XP/Vista and
UNIX-like systems. The driver establishes
a transparent connection between host and
serial device by mapping the IP:Port of the
WE-2100T’s serial port to a local COM
port on the host computer.
The driver used for Real COM Mode comes with the Network Enabler Administrator which is
installed automatically on your computer when you install the Network Enabler 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 or wireless interface. At the other end of the connection, the WE-2100T accept the WLAN
frame, unpack the TCP/IP packet, and then transparently send it to the appropriate serial device
attached to the WE-2100T’s serial port.
Real COM Mode allows several hosts to have access control of the same WE-2100T. The Moxa
driver that comes with your WE-2100T 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.
RFC2271 Mode
RFC-2217 mode is similar to Real COM mode. That is, a driver is used to establish a transparent connection
between a host computer and a serial device by mapping the serial port on the WE-2100T to a local COM port
on the host computer. RFC2217 defines general COM port control options based on the Telnet protocol. Third
party drivers supporting RFC-2217 are widely available on the Internet and can be used to implement Virtual
COM mapping to your WE-2100T serial port.

Chapter 5 Initial IP Address Configuration
When setting up your WE-2100T 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
WE-2100T’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:

NE-4100 Series User’s Manual Initial IP Address Configuration
5-2
Initializing WE-2100T’s IP Address
1. Determine whether your WE-2100T will use a Static IP or Dynamic IP (either DHCP or
BOOTP application).
2. If WE-2100T is used in a Static IP environment, you can use Network Enabler
Administration Suite, ARP, Web Console, Telnet Console, or Serial Console to configure the
new IP address.
3. If WE-2100T is used in a Dynamic IP environment, you can use Network Enabler
Administration suite, Web Console, Telnet Console, or Serial Console to configure
WE-2100T 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 WE-2100T) 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 WE-2100T module.
Factory Default IP Address
WE-2100T is configured with the following default private IP address:
Ethernet default IP address: 192.168.126.254
WLAN 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.
WE-2100T 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.)
Network Enabler Administration Suite
Network Enabler Administration Suite consists of some useful utilities that are used to configure
and manage your WE-2100T embedded module.
See Chapter 7 for details on how to install Network Enabler Administration Suite, and how
to use this suite of useful utilities to set up IP addresses and configure your WE-2100T
embedded module.
ARP
You can use the ARP (Address Resolution Protocol) command to set up an IP address for your
WE-2100T. The ARP command tells your computer to associate the WE-2100T’s MAC address
with the intended IP address. You must then use Telnet to access the WE-2100T, at which point
the WE-2100T’s IP address will be reconfigured.
In order to use this setup method, both your computer and WE-2100T must be connected to the same
LAN.
You may also use a cross-over Ethernet cable to connect the WE-2100T directly to your computer’s
Ethernet card.
Your WE-2100T 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 WE-2100T from your network administrator.
2. Obtain the WE-2100T’s MAC address from the label on the module.
3. Execute the ‘arp -s’ command from your computer’s MS-DOS prompt by typing:
![](/img.php?id=819430&img=bg19.png)
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 WE-2100T. You will need to use both numbers, as described above in points 1 and 2.
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 WE-2100T 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 WE-2100T 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 192.168.126.254 (use the

Time server
Setting Factory Default Necessity
IP or Domain address
(E.g., 192.168.1.1, time.stdtime.gov.tw, or
time.nist.gov)
None Optional
WE-2100T uses SNTP (RFC-1769) for auto time calibration.
Input the correct “Time Server” IP address or domain address. Once WE-2100T is configured
with the correct Time Server address, WE-2100T will request time information from the “Time
Server” every 10 minutes.
Console
The “Disable” option for Web Console and Telnet Console is included 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 your WE-2100T. The factory default for both Web
Console and Telnet Console is Enable.
Setting Factory Default Necessity

You must assign a valid IP address to WE-2100T before it will work in your network environment.
Your network system administrator should provide you with an IP address and related settings for
your network. The IP address must be unique within the network (otherwise, WE-2100T will not
have a valid connection to the network). First time users can refer to Chapter 5, Initial IP address
Configuration, for more information.
You can choose from four possible IP Configuration modes—Static, DHCP, DHCP/BOOTP,
and BOOTP—located under the web console screen’s IP configuration drop-down box.

(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.

6-6
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 WE-2100T 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 WE-2100T, a
connection is established directly from the WE-2100T. 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. WE-2100T 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 configuration
Setting Factory Default Necessity
Static
DHCP
DHCP/BOOTP
BOOTP
Static Required
In Dynamic IP environments, the firmware will retry 3 times every 30 seconds until network settings
are assigned by the DHCP or BOOTP server. The Timeout for each try increases from 1 second, to 3
seconds, to 5 seconds.
If the DHCP/BOOTP Server is unavailable, the firmware will use the default IP address,
192.168.127.254, Netmask, and Gateway for IP settings.
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
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 WE-2100T’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. WE-2100T 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. WE-2100T 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.

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
Specify the location string for SNMP agents such as WE-2100T Series. This string is usually set
to the street address where the WE-2100T is physically located.
IP Address Report
When WE-2100T is used in a dynamic IP environment, users must spend more time with IP
management tasks. For example, WE-2100T 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. WE-2100T
helps 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 WE-2100T’s Auto IP report.
1. Use Network Enabler 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
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
Port Alias is specially designed to allow easy identification of the serial devices which are
connected to NE-4100 Series’ serial port.
Serial Parameters
Check the serial communication parameters in your Serial Device’s user’s manual. You should set up
WE-2100T’s serial parameters with the same communication parameters used by your serial devices.
Baud rate

FIFO setting when your serial device does not have a FIFO to prevent data loss during
communication.
Operating Settings
Click on the Operating Settings link on the left side of the screen to display operating settings.
Make necessary changes to the settings and then click on Submit to validate the modifications.
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: WE-2100T automatically closes the TCP connection if there is no TCP activity for
the given time. After the connection is closed, WE-2100T 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: WE-2100T 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 WE-2100T will check the
connection status between the WE-2100T and 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. WE-2100T will then force the existing TCP connection to close.
![](/img.php?id=819430&img=bg26.png)
NE-4100 Series User’s Manual Web Console Configuration
6-10
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:
WE-2100T 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 WE-2100T
serial port, at the same time. When multiple hosts establish a TCP connection to the specific serial
port at the same time, WE-2100T 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 WE-2100T
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 WE-2100T receives both delimiters through its serial port, it immediately packs all data
currently in its buffer and sends it out the WE-2100T’s 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 WE-2100T 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 WE-2100T’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 WE-2100T fetches the serial data from its
internal buffer. If data is being received through the serial port, the WE-2100T stores the data in
its internal buffer. WE-2100T 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
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
![](/img.php?id=819430&img=bg27.png)
NE-4100 Series User’s Manual Web Console Configuration
6-11
( 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
WE-2100T 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 WE-2100T
module’s internal buffer size. WE-2100T’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 WE-2100T uses to listen to connections, and that other devices must use to
contact WE-2100T. 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
WE-2100T 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: WE-2100T automatically closes the TCP connection if there is no TCP activity for
the given time. After the connection is closed, WE-2100T 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.
Max. connection 1:
Allows only 1 host’s Real COM driver to open the specific WE-2100T serial port.
![](/img.php?id=819430&img=bg28.png)
NE-4100 Series User’s Manual Web Console Configuration
6-12
Max connection 2 to 4:
Allows 2 to 4 host’s Real COM drivers to open the specific WE-2100T 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 WE-2100T from the Ethernet
interface.
When Max Connection is not 1, it also means that WE-2100T will be in “multi connection
application.” In the “multi connection application,” when one of two to four hosts closes the COM
port, WE-2100T will suspend receiving or sending serial data until the host successfully closes the
COM port.
In multi connection applications, WE-2100T will use the serial communication parameters set in the
console. If the host opens the COM with parameters different from WE-2100T’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 WE-2100T receives both delimiters through its serial port, it immediately packs all data
currently in its buffer and sends it out the WE-2100T’s 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 WE-2100T 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 WE-2100T’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 WE-2100T 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. WE-2100T 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.

WE-2100T 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 WE-2100T’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: WE-2100T 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: WE-2100T automatically closes the TCP connection, if there is no serial data
activity for the given time.
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 a
connection close request is received. Although the inactivity time is disabled, the WE-2100T will
check the connection status between the WE-2100T 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. WE-2100T 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.

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 WE-2100T receives both delimiters through its serial port, it immediately packs all data
currently in its buffer and sends it out the WE-2100T’s 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 WE-2100T 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 WE-2100T’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 interval during which WE-2100T fetches the serial data from its
internal buffer. If there is incoming data through the serial port, WE-2100T stores data in the
internal buffer. WE-2100T 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
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 WE-2100T
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 WE-2100T is 1 Kbyte per port.

Up to 4 connections can be established between WE-2100T and hosts. The connection speed or
throughput may be low if one of the four connections is slow. In this case, the other 3 connections will
be delayed while waiting for the slowest connection to finish transmitting or receiving.
The “Destination IP address” parameter can use both IP address and Domain address. For some
applications, the user may need to send the data actively to the remote destination domain address.

Event Type
Cold start
This refers to starting the system from power off (contrast this with warm start). When performing
a cold start, WE-2100T 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, WE-2100T 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, WE-2100T will immediately send an e-mail or send an SNMP trap.
IP address changed
The user has changed WE-2100T’s IP address. When the IP address changes, WE-2100T will
send an e-mail with the new IP address before WE-2100T reboots. If the WE-2100T fails to send
mail to the mail server after 15 seconds, WE-2100T will reboot directly and abort the mail auto
warning.
Password changed
The user has changed WE-2100T’s password. When the password changes, WE-2100T will send
an e-mail with the password change notice before WE-2100T reboots. If the WE-2100T fails to
send mail to the mail server after 15 seconds, WE-2100T 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, WE-2100T 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, WE-2100T will immediately send an e-mail or send an SNMP trap.

Overview
We understand the importance of software as the foundation of your application, and with this in
mind, we designed Network Enabler Administrator to let you easily install and configure your
WE-2100T Series products over the network. Network Enabler Administrator provides five
function groups that ease the installation process, allows off-line COM mapping, and provides
monitoring and IP location server functions.
Network Enabler Administrator is an integrated software suite that bundles Network Enabler
Administrator and the IP Serial Library, and provides everything you need to remotely manage,
monitor, and modify your WE-2100T—hassle free.

COM Mapping
Network Enabler Administrator Suite comes with Windows 95/98/ME/NT/2000/XP/Vista Real
COM drivers. After you install Network Enabler Administrator Suite, there are two ways to set up
the WE-2100T’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
WE-2100T 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 WE-2100T
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 WE-2100T to different fields.
Use the following procedure to map COM ports:
1. On-line COM Mapping:
Connect WE-2100T to the network Æ Set WE-2100T to the proper IP address Æ Map COMs
to your host Æ Apply Change.
2. Off-line COM Mapping:
Map COMs to your host Æ Apply Change Æ Connect WE-2100T to the network Æ
Configure WE-2100T’s IP address.
On-line COM Mapping
1. Broadcast Search for
WE-2100Ts on the
network.
2. Select the COM Mapping
function group.

3. Add the target that you
would like to map COM
ports to.
4. The WE-2100T list that
appears is based on the
Broadcast Search. Select
the WE-2100T 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 WE-2100Ts, remember to
check the “Auto Enumerating” function
to use the COM No. you select as the
first COM No.

7. Hi-performance mode is the default for Tx mode. If the driver
completes sending data from the host to the WE-2100T, 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 WE-2100T; 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, WE-2100T 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 WE-2100T 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.

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 WE-2100T 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

Appendix C DIO Commands
In this appendix, we give the reference DIO commands used to access the Digital I/O status of the
Network Enabler from an Ethernet network. The Digital I/O status can be accessed by a specific
TCP port (default 5001) on the Network Enabler.
Command Packet Format:
Length (Bytes) 4 1 – 255
Format *Header Data
Send the Command packet to the Network Enabler. “Data” field is command specific.
ACK Packet Format:
Length (Bytes) 4 1 -255
Format *Header Data
The Network Enabler returns by ACK packet. You can get the Digital I/O status and input/output
operation mode by checking the “Data” field of the packet.
*Header Format:
Length (Bytes) 1 1 1 1
Format Command Version
(must be 2) Command Status Length (for data)
Check the “Command Status” to get the result after sending the Command packet.
Command: This field defines the command code. For example, 1(hex) represents “read single D
I/O.” For more information, please refer to following content.
Command Status: This field returns the status of the command.
0 – OK
1 – Command error; may be unknown
2 – Version error; not supported by this version
3 – Length error; the length member does not match the attached data
4 – Operation error; you cannot set the DIO mode to input mode, and set the DO status at
the same time
5 – “Packet too short” error
6 – DIO number error; might not support request DIO number
0xFF – other unknown error
