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 requires 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.
