Ethernet Configuration
This chapter describes how to use the
NI Ethernet Device Configuration
utility to configure the network parameters of the GPIB-ENET/100. You
can use this utility for any of the following purposes:
•
Manually configure the network parameters or enable DHCP
•
Verify or change the hostname
•
Add or change a comment to help identify the device
Your GPIB-ENET/100 must be in network configuration mode when you
make any changes to the network parameters.
Entering Network Configuration Mode
If DHCP is available on your network, it configures the network parameters
for your GPIB-ENET/100 at startup, as described in the
section of Chapter 2,
. In this case, using
the
NI Ethernet Device Configuration
utility is not necessary.
If the GPIB-ENET/100 is configured to use DHCP and DHCP is
unavailable, the unit automatically enters network configuration mode after
a 60 second timeout. The GPIB-ENET/100 must be in this mode before
you can make changes to the network parameters.
You also can enter network configuration mode during normal operation by
pressing and holding the CFG RESET switch for three seconds. Refer to
the
section in Chapter 6,
for more information on using this switch.
While in network configuration mode, the
PWR/RDY
LED alternates
rapidly between red and yellow, and normal operation is halted.
Note
If you only want to view the network configuration settings without making
changes, you do not need to place the unit into network configuration mode. While in
normal operation, you can run the utility as described in the following section,
NI Ethernet Device Configuration Utility
, and examine the properties for any National
Instruments Ethernet device on your subnet. However, any changes you attempt to make to
the network parameters while in normal mode will not take effect.
