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.
If this is the case, you should set the default gateway to
0.0.0.0
and leave the two DNS server
parameters blank.
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
in a Web browser and entering Info Code
GPIBENET1000FW
.
Caution
Do
not
power-off the GPIB-ENET/1000 or disconnect the power supply
while updating the firmware. Doing so could damage the unit. The
GPIB-ENET/1000 reboots automatically when the update completes.
You can update the firmware from the GPIB-ENET/1000 Web Configuration page. To access
the GPIB-ENET/1000 Web Configuration page, enter the IP address or hostname into the
browser address bar. In the
Details
section of the web page, click
Update
under the
Firmware
heading.
READY LED Signaling
The
READY
LED blinks red slowly in a distinct pattern to alert you of internal errors. Use this
section to interpret and record the pattern that the
READY
LED flashes, and then contact
National Instruments.
