4. Refer to the Baseplate Identification Label on the base of the GPIB-ENET/1000 and make
a note of the serial number, MAC address (Ethernet address), and default hostname. You
will need this information when you run some of the utilities.
5. Contact your network administrator to determine whether your network supports DHCP or
if you need to manually perform the Ethernet configuration to set up the network
parameters. If your network uses DHCP, the network configuration is performed
automatically at startup. If your network does not use DHCP, Auto IP (link-local)
addressing is used to acquire an initial IP address. A steady green READY LED indicates
the GPIB-ENET/1000 finished its boot process and acquired its IP address. The unit is now
ready to operate. You may need to run software configuration and verification utilities at
this time.
6. Connect the GPIB cable to the GPIB-ENET/1000. Connect the other end to your GPIB

Baseplate Identification Label
When you configure the GPIB-ENET/1000 for use on your network, you will need to
differentiate it from other network devices. Every GPIB-ENET/1000 has a unique serial number,
Ethernet address, and default hostname. You can find this information on the baseplate
identification label on the GPIB-ENET/1000.
Note The Ethernet address is not the IP address. All devices on an Ethernet network
are assigned a unique physical address—the Ethernet address, also known as the
MAC address—so they can communicate with each other.
Figure 7. GPIB-ENET/1000 Baseplate Identification Label
Startup
Turn on the front-panel power switch. The POWER LED lights steady green. The READY
LED blinks green rapidly while the GPIB-ENET/1000 completes its boot process and attempts
to acquire its network parameters.
By default, the GPIB-ENET/1000 attempts its network configuration automatically through
DHCP. If there is no DHCP response, the GPIB-ENET/1000 reverts to Auto IP addressing and
assigns itself an IP address in the range of 169.254.x.x. Refer to Auto IP Addressing for more
information. The time required for assigning the IP address depends on your network and the
configuration of your GPIB-ENET/1000. Allow up to 30 seconds and observe the state of the
READY LED to determine the outcome of the boot process. One of the following should occur:
• A steady green READY LED indicates the GPIB-ENET/1000 finished the boot process
and acquired its IP address. The unit is now ready to operate. When using DHCP, the
GPIB-ENET/1000 typically is ready to operate about 15 seconds after you power it on.
• If the READY LED blinks a slow red pattern, the GPIB-ENET/1000 boot process failed.
Refer to READY LED Signaling to interpret the flash pattern before calling National
Instruments Technical Support.
• A steady red READY LED indicates that the GPIB-ENET/1000 has corrupt firmware and
has entered Safe Mode. The only operation allowed in Safe Mode is to update the firmware.
Refer to the Firmware Update section for instructions on how to update the firmware.

(Windows 8) Click NI Launcher and select GPIB Ethernet Wizard. Accept the
GPIB-ENET/1000 default configuration settings or change them while running the wizard.
On Mac and Linux, use the Add GPIB Hardware Wizard to add the GPIB-ENET/1000 to your
system. Click New to launch the Add GPIB Hardware Wizard from the GPIB Explorer utility in
the installed NI-488.2 or ni4882 directory. Once the GPIB-ENET/1000 is recognized, you
can change the configuration settings as described in the Ethernet Configuration section.
Refer to the installation guide on the media for more details about the GPIB Ethernet Wizard,
Add GPIB Hardware Wizard, and GPIB Explorer utility.
Ethernet Configuration
The GPIB-ENET/1000 uses a Web page for device configuration. If your network uses DHCP,
the network configuration is performed automatically at startup, and you should not need the
GPIB-ENET/1000 Configuration Web page unless you need to modify the hostname or update
the firmware.
In addition to manually configuring the network parameters, you can use the GPIB-ENET/1000
Configuration Web page for any of the following purposes:
• Enable DHCP/Auto IP addressing
• Verify or change the hostname
• Add or change a comment to help identify the device
• Change the administrator password
• Update firmware
Once the GPIB-ENET/1000 has been added to your system, you may need to remove it and add
it again if you modify the configuration of a GPIB-ENET/1000.
Using the GPIB-ENET/1000 Configuration Web Page
You can access the GPIB-ENET/1000 Configuration Web page in most browsers. Enter the IP
address or hostname into the browser’s address bar. Anyone can view the current configuration
at any time. However, changes to the configuration or firmware updates proceed only after you
enter the proper password.
Changing the Network Settings
Complete the following steps to change the network settings:
1. Navigate to the GPIB-ENET/1000 Configuration Web page using a browser.
The current hostname is displayed. The hostname associates a name with a numerical IP
address. Hostname is a required field.
The GPIB-ENET/1000 attempts to use the hostname when registering with DHCP. Many
DHCP servers have the ability to register the hostname and the assigned IP address. You
then can reliably use the hostname to communicate with your GPIB-ENET/1000 even if the
numerical IP address changes.
Some DHCP servers do not implement hostname registration. The GPIB-ENET/1000
requires Domain Name Server (DNS) registration when using DHCP. If your DHCP server

16 |ni.com |GPIB Hardware Installation Guide and Specifications
does not support DNS registration, you must use an Auto IP address or static network
parameters.
2. Choose whether you need to use DHCP with Auto IP fallback or a static IP configuration.
• 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.
• 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.x.x. 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.
•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, leave these parameters blank.

GPIB Hardware Installation Guide and Specifications |© National Instruments |17
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
ni.com/info 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.

18 |ni.com |GPIB Hardware Installation Guide and Specifications
Note By recording the READY LED status messages before calling National
Instruments, you can save yourself time, and the Product Support Department can
answer your questions more accurately and efficiently. Do not switch off power to
your GPIB-ENET/1000 before recording the blinking READY LED pattern.
READY LED signaling can report up to 81 different errors. The errors are numbered from
11 to 99 and are reported through sequences of READY LED flashes.
Note There is no zero in any error message. This means that error message numbers
0 to 10, 20, 30, 40, 50, 60, 70, 80, and 90 are not possible.
Step 1. Count the Long Flashes
A three-second interval, during which the READY LED is off, separates each repetition of the
sequence. The sequence begins with a series of long one-second flashes—that is, one second red,
one second off. These long flashes represent the digit in the tens column. There can be one to
nine long flashes, which represent digits 1 through 9. For example, one long flash represents the
digit 1 in the tens column, and nine long flashes represent the digit 9 in the tens column.
Step 2. Count the Short Flashes
The long flashes are followed by shorter flashes; each short flash lasts about one-fifth of a
second—that is, one-fifth of a second red, one-fifth of a second off. These short flashes represent
the digit in the ones column. Again, there can be one to nine flashes, which represent the digits
1 through 9. For example, one short flash represents the digit 1 in the ones column, and
nine short flashes represent the digit 9 in the ones column.
Using this method, the READY LED flashes the following sequence to represent status
message 11:
<three seconds off> <one long red flash> <one short red flash>
<three seconds off>…
The READY LED flashes the following sequence to represent status message 31:
<three seconds off> <three long red flashes> <one short red flash> <three seconds off>…
Step 3. Record Your Status Code Number
When you have computed your error message number, write it down and also note the

You can use this switch at power on to reset the unit to its factory settings. By pressing and
holding the CFG RESET switch while you power on the GPIB-ENET/1000, all settings revert
to the factory settings as follows:
• DHCP with Auto IP fallback.
• Default hostname as printed on the baseplate label.
• Administrator password is pass.
You must press and hold the switch until the READY LED blinks yellow. If you release
the switch prior to the READY LED blinks yellow, no change occurs to the network
configuration, and the GPIB-ENET/1000 continues to boot normally.
Once the READY LED blinks yellow, release the CFG RESET switch. The GPIB-ENET/1000
resets to its default network characteristics and resumes the boot process. The READY LED
indicates the boot process progress, as described in Table 3.
