NPort W2150A/W2250A Series  Web Console: Network Settings 
7-7 
Description  This field is for the IP address that will be assigned to your NPort device server. 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 that is unique and valid in your WLAN 
environment. If your device server will be assigned a dynamic IP address, set the IP 
configuration parameter appropriately. 
Netmask 
Default  255.255.255.0 
Options  Netmask setting (e.g., “255.255.0.0”) 
Description  This field is for the subnet mask. A subnet mask represents all of the network hosts at one 
geographic location, in one building, or on the same LAN. When a packet is sent out over 
the network, the NPort device server will use the subnet mask to check whether the 
desired TCP/IP host specified in the packet is on the local network segment. If the address 
is on the same network segment as the device server, a connection is established directly 
from the device server. Otherwise, the connection is established through the gateway as 
specified in the Gateway parameter. 
Gateway 
Default 
Options  IP address (e.g., “192.168.1.1”) 
Description  This field is for the IP address of the gateway, if applicable. A gateway is a network 
computer 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. The 
NPort device server needs to know the IP address of the default gateway computer in 
order to communicate with the hosts outside the local network environment. Consult your 
network administrator if you do not know how to set this parameter.
