NPort W2150A/W2250A Series Web Console: Network Settings
6-4
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 local area network. 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.
ATTENTION
In dynamic IP environments, the NPort will send 3 requests every 30 seconds to the DHCP or BOOTP server
until the network settings have successfully been assigned. The first request will time out after one second; the
second request will time out after three seconds, and the third request will timeout after five second. If the
DHCP or BOOTP server is unavailable, the NPort will use the factory default networ
k settings.
