2. Choose whether you need to use DHCP with Auto IP fallback or a
static IP configuration.
a. Leaving the checkbox unchecked enables DHCP with Auto IP
fallback. You do not need to enter any network parameters unless
you want to change the Ethernet device hostname.
b. To use static IP configuration, check the Static IP Configuration
checkbox. Enter the Static IP Parameters you have chosen for the
host IP Address, Subnet Mask, Default Gateway, Primary DNS
Server, and Secondary DNS Server.
3. You can enter an optional comment to help you identify each device.
4. When your configuration is complete, save the configuration to the
GPIB-ENET/1000. You must supply the correct administrator
password prior to the settings being saved.
The GPIB-ENET/1000 applies the setting changes immediately. There is
no need to reboot the interface.
Auto IP Addressing
Auto IP addressing, also referred to as link-local addressing, allows a
network device to obtain its network identity automatically and advertise
its presence without other network servers being required, such as DHCP
and DNS. An Auto IP address is in the form of
169.254.

. This type
of addressing is useful for connecting the GPIB-ENET/1000 directly to a
Windows PC.
To determine the Auto IP address the GPIB-ENET/1000 is using, you need
to discover the interface using Measurement & Automation Explorer or the
GPIB Ethernet Wizard. In addition to an automatically assigned IP address,
Auto IP also consists of a “local name” responder. You should be able to
access the GPIB-ENET/1000 using the hostname followed by
.local,
such as
nienetba5bf1.local.
Static IP Parameters
If DHCP is not available and you do not want to use Auto IP, you must
provide the GPIB-ENET/1000 with several important network parameters.
• IP address—The unique, computer-readable address of a device on
your network. An IP address typically is represented as four decimal
numbers separated by periods (for example,
130.164.54.215).
Refer to the Choosing a Static IP Address section.
• Subnet Mask—A bit mask that helps the network device determine
whether another device is on the same network or a different network.
