•
Default Gateway
—The IP address of a device that acts as a gateway,
which is a connection between two networks. If your network does not
have a gateway, set this parameter to
0.0.0.0
.
•
Primary DNS Server/Secondary DNS Server
—The IP address of
a network device that stores hostnames and translates them into IP
addresses. If your network does not have a DNS server, set this
parameter to
0.0.0.0
.
Choosing a Static IP Address
For a Network Administered by a Network Administrator
If you are adding the GPIB-ENET/1000 to an existing Ethernet network,
you must choose IP addresses carefully. Contact your network
administrator to obtain an appropriate static IP address for your
GPIB-ENET/1000. Also have the network administrator assign the proper
subnet mask, gateway, and DNS server addresses.
For a Network without a Network Administrator
If you are assembling your own small Ethernet network, you can choose
your own IP addresses. The format of the IP addresses is determined by
the subnet mask. You should use the same subnet mask as the computer
you are using with your GPIB-ENET/1000. If your subnet mask is
255.255.255.0
, the first three numbers in every IP address on the
network must be the same. If your subnet mask is
255.255.0.0
, only the
first two numbers in the IP addresses on the network must match.
For either subnet mask, numbers between 1 and 254 are valid choices for
the last number of the IP address. Numbers between 0 and 255 are valid for
the third number of the IP address, but this number must be the same as
other devices on your network if your subnet mask is
255.255.255.0
.
If you are setting up your own network, you probably do not have a gateway
or DNS server, so you should set these values to
0.0.0.0
.
Firmware Update
The GPIB-ENET/1000 software includes a firmware update feature you
can use to access new features that may be added to the GPIB-ENET/1000
in the future. You must update the firmware to take advantage of any new
features. You can obtain the latest upgrade by navigating to
