Wiring Requirements
ATTENTION
Before connecting the hardware, follow these important wiring safety precautions:
Disconnect power source
Do not install or wire this unit or any attached devices with the power connected. Disconnect the
power before installation by removing the power cord before installing and/or wiring your unit.
Follow maximum current ratings
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.
Use caution - unit may get hot
The unit will generate heat during operation, and the casing may feel hot to the touch. Take care
when handling unit. Be sure to leave adequate space for ventilation.
The following guidelines will help ensure trouble-free signal communication:
z Use separate paths to route wiring for power and devices to avoid interference. Do not run

Installing onto the WE-2100T-ST Evaluation Board
The WE-2100T-ST evaluation board is a tool to help you develop your WE-2100T application.
The module must first be installed on the board before the power supply, network, and serial
device are connected. Align the sockets on the WE-2100T module with the pins on the
WE-2100T-ST board, as shown in the following figure.

The bottom row of pins is for connecting a 5V power supply; the next row up is for connecting a
3.3V power supply. Digital I/O pins are located on the right side. The top row of pins is for
grounding.
Connecting to the Network
When developing your application, you may wish to use Ethernet to configure the WE-2100T,
especially if your wireless LAN is not functional yet. You may connect to the network using the
evaluation board’s RJ45 Ethernet port. In order to use the LAN connection, make sure the network
cable is already plugged in before the unit is powered on.
After power is connected in the next step, the RJ45 connector will indicate a valid connection to
the Ethernet as follows:
LAN
A green LED indicator indicates a valid 100 Mbps Ethernet network connection
and will flicker as data is being transmitted.
LAN
A yellow LED indicator indicates a valid 10 Mbps Ethernet network connection
and will flicker as data is being transmitted.
Connecting the Power
Connect the 12 to 48 VDC power line to the power jack on the evaluation board.
Connecting to a Serial Device
Use a serial cable to connect the serial device to the data port, P2, on the evaluation board. (P1 is
the console port, which is used for the serial console.)

DI/O Test Settings
The WE-2100T includes 9 digital I/O channels. Each digital I/O channel is a GPIO (General
Purpose I/O) channel that can be set to “digital output” or “digital input” mode by software. When
developing your own applications, be aware of the voltage limits. The output current is 1 mA.

The output current for each digital output channel carries only 1 mA.
On the evaluation board, the DIO mode jumper selects whether a digital channel will be connected
to the DIP switch for input testing, or to the LED for output testing. If DIO1 is set to digital input
mode on the WE-2100T, you can use a jumper setting on the evaluation board to connect DIO1 to
the DIP switch. Digit one on the DIP switch will then be the input device for DIO1. When you flip
the switch on or off, you can see the status of DIO1 change on the web console or in the Windows
utility.
1. First, position the jumpers so they correspond with the input/output mode of each digital I/O
channel. In the example below, channels 0 through 3 are output (DO) channels and channels 4
through 8 are input (DI) channels.
2. After setting the jumpers, use the DIP switches to set the status for input channels 0 through 3.
You can set the status to either lo w (on) or high (off). In the example below, channel 0 is set
to low, and channels 1 through 3 are set to high. Note that channel 0 corresponds to switch 1.

3. Use the web console to set the status of output channels. If you set channel 4’s status to
“Low” and the others to “High,” the DO4 LED will glow and the other LEDs will remain
dark. Please refer to Chapter 9 for more configuration details.

Chapter 4 Selecting an Operation Mode
In this section, we describe the available operation modes for the WE-2100T. There is a mode that
relies on a driver installed on the host computer, and other modes that rely on TCP/IP socket
programming concepts. After determining the proper operation mode for your application, please
refer to Chapter 8 for instructions on configuring that mode.

TCP Server Mode
TCP Client Mode
UDP Mode
Real COM Mode
WE-2100T Series User’s Manual Selecting an Operation Mode

Overview
The WE-2100T connects serial devices to the wireless LAN. It has a built-in TCP/IP stack that
saves you the effort of programming networking protocols. Simply select the proper operating
mode to allow your computer to access, manage, and co nfigure your serial device over the
Internet.
Traditional SCADA and data collection systems collect data from various instruments over serial
connections (RS-232/422/485). Since WE-2100T is designed to convert between serial and
Ethernet signals, both local and remote devices can be connected to a standard TCP/IP network
and made accessible to SCADA and data collection systems.
Real COM and RFC2217 modes allow serial-based software to access the module’s serial port as
if it were a local serial port on a PC. These modes are appropriate when your application relies on
Windows or Linux software that was originally designed for locally attached COM or TTY
devices. With these modes, you can access your devices from the network using your existing
COM/TTY-based software, without investing in additional software.
Three different socket modes are available for user-developed socket programs: TCP Server, TCP
Client, and UDP Server/Client. For TCP applications, the appropriate mode depends on whether
the connection will be hosted or initiated from the module’s serial port or from the network. 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 multi-unicasting of
data to groups of IP addresses and would be suitable for streaming media or non-critical messaging
applications such as LED message boards.
TCP Server Mode
In TCP Server mode, the module’s serial port is
assigned an IP:port address that is unique on your
TCP/IP network. It wai ts for the host computer to
establish a connection to the attached serial
device. This operation mode also supports up to
four simultaneous connections, so multiple hosts
can collect data from the attached device at the
same time.
Data transmission proceeds as follows:
1. A host requests a connection to the module’s
serial port.
2
. Once the connection is established, data can
be transmitted in both directions—from the
host to the device, and from the device to the
host.
WE-2100T Series User’s Manual Selecting an Operation Mode
4-3
TCP Client Mode
In TCP Client mode, the module actively
establishes a TCP connection to a specific
network host when data is received from the
attached serial device. After the data has been
transferred, the module can automatically
disconnect from the host computer through the
Inactivity time settings. Please refer to Chapter
8 for details on these parameters.
Data transmission proceeds as follows:
1. The module requests a connection from the
host.
2. The connection is established and data can
be transmitted in both directions between
the host and device.
UDP Mode
UDP is similar to TCP but is faster and more
efficient. Data can be broadcast to or received
from multiple network hosts. Howe ver , UD P
does not support verification of data and would
not be suitable for applications where data
integrity is critical. It is ideal for message
display applications.
Real COM Mode
Real COM mode is designed to work with
drivers that are installed on a network host.
COM drivers are provided for Windows
systems, and TTY drivers are provided for
Linux and UNIX systems. The driver
establishes a transparent connection to the
attached serial device by mapping a local serial
port to the module’s serial port. Real COM
mode supports up to four simultaneous
connections, so multiple hosts can collect data
from the attached device at the same time.
WE-2100T Series User’s Manual Selecting an Operation Mode
4-4
ATTENTION
Real COM drivers are installed and configured through the included Windows utility.
Real COM mode allows you to continue using your serial communications software to access
devices that are now attached to the WE-2100T module. On the host, the Real COM driver
automatically intercepts data sent to the COM port, packs it into a TCP/IP packet, and redirects it
to the network. At the other end of the connection, the WE-2100T accepts the Ethernet frame,
unpacks the TCP/IP packet, and sends the serial data to the appropriate device.
ATTENTION
In Real COM mode, several hosts can have simultaneous access control over the serial port on the
module. If necessary, you can limit access by using the Accessible IP settings. Please refer to
Chapter 9 for additional information on Accessible IP settings.

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, please refer to Chapter 7.
This chapter includes the following sections:
Selecting an IP Address or Configuration
Assigning IP Address with Network Enabler Administration Suite
Assigning IP Address with ARP
Assigning IP Address with Telnet Console
Assigning IP Address with Serial Console
WE-2100T Series User’s Manual Initial IP Address Configuration
5-2
Selecting an IP Address or Configuration
For most applications, you will assign a fixed IP address to the module, which means that you set
the IP address directly. However, for certain network environments, your module’s IP address will
need to be assigned by a DHCP or BOOTP server. In this case, instead of directly assigning the
module’s IP address, you will need to configure the module to receive its IP address from the
appropriate DHCP or BOOTP server.
If you are not sure whether you need to configure your module for a dynamic or static IP address,
consult the administrator who set up the LAN. You will also need to consult the network
administrator if you wish to use a fixed IP address in a DHCP or BOOTP environment.
Factory Default IP Address
Network Interface IP Configuration IP Address
LAN Static 192.168.126.254
WLAN Static 192.168.127.254
If the module is configured to obtain its IP settings from a DHCP or BOOTP server but is unable
to get a response, it will use the factory default IP address and netmask.
The 192.168.xxx.xxx set of addresses are private IP addresses, since they cannot be directly
accessed from a public network. You cannot ping a device with a 192.168.xxx.xxx address from an
outside Internet connection. If your application requir es sending data over a public network, such
as the Internet, you will need to assign a valid public IP address, which can be leased from a local
ISP.
Assigning IP Address with Network Enabler Administration
Suite
Please refer to Chapter 12 for instructions on using Network Enabler Administrator to configure
and manage your WE-2100T embedded module.
Assigning IP Address with ARP
The ARP (Address Resolution Protocol) command can be used to assign an IP address to the
module. The ARP command tells your computer to associate the module’s MAC address with the
specified IP address. You must then use Telnet to access the module, at which point the module’ s IP
address will be reconfigured. This method only works when the module is configured with default
IP settings.
ATTENTION
When using ARP to set the module’s IP address, be aware of the following items:
z Your computer and your module must be connected to the same LAN or WLAN. You may use
a cross-over Ethernet cable to connect the module directly to your computer’s Ethernet port.
z Your module must be configured with the factory default IP address before executing the ARP
command. When connected to a LAN, the default IP is 192.168.126.254. When connected to a
WLAN, the default IP is 192.168.127.254.
WE-2100T Series User’s Manual Initial IP Address Configuration
5-3
1. Select a valid IP address for your WE-2100T module. Consult with your network
administrator if necessary.
2. Obtain the module’s MAC address from the label on the module.
3. From the DOS prompt, execute the arp -s command with the desired IP address and the
module’s MAC address, as in the following example:
arp -s 192.168.200.100 00-90-E8-xx-xx-xx
In this example 192.168.200.100 is th e new IP address that you wish to assign to the module,
and 00-90-E8-xx-xx-xx is the module’s MAC address.
4. From the DOS prompt, execute a special Telnet command using port 6000, as in the
following example:
telnet 192.168.200.100 6000
In this example, 192.168.200.100 is the new IP address that is being assigned to the module.
5. You should see a message indicating that the connection failed.
6. The module will automatically reboot with the new IP address. You can verify that the
configuration was successful by connecting to the new IP address with Telnet, ping, or
another method.
Assigning IP Address with 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. T his can be done using the Telnet
program.
1. Select Run… from the Windows Start menu.
2. Enter the telnet command using your module’s current IP address and click OK.
