Introduction  
Optional Programming Tools  
Your kit includes the NI-488.2 software for Macintosh. In addition, you can order the  
LabVIEW software from National Instruments. LabVIEW includes instrument driver  
libraries that make it easier to communicate with your GPIB instruments.  
LabVIEW is a complete programming environment that departs from the sequential  
nature of traditional programming languages and features a graphical programming  
environment. It includes all the tools needed for instrument control, data acquisition,  
analysis, and presentation. When you order LabVIEW, you also get more than 300  
complete instrument drivers, which are modular, source-code programs that handle the  
communication with your instrument so that you do not have to learn the programming  
details.  
For more information about LabVIEW, contact National Instruments.  
Hardware Description  
The GPIB-ENET transparently handles data transfers between an Ethernet-based TCP/IP  
host and the GPIB. With the GPIB-ENET, multiple hosts can share a set of GPIB  
instruments or a single host can control several GPIB systems.  
The GPIB-ENET converts a computer equipped with an NI-488.2 driver and an Ethernet  
port into a GPIB Talker/Listener/Controller. The GPIB-ENET is powered by a 100 to  
120 VAC or 220 to 240 VAC supply.  
The GPIB-ENET has all the software and logic required to implement the physical and  
electrical characteristics of all versions of the ANSI/IEEE 488 standard, including  
ANSI/IEEE Standard 488.2-1987, and ANSI/IEEE Standard 802.3. The GPIB-ENET  
interprets and executes commands that you send to it over an Ethernet link and performs  
all necessary Ethernet-to-GPIB protocol conversions.

Chapter 2  
Hardware Configuration and Installation  
This chapter gives instructions for configuring the 10Base-T and coax versions of the  
GPIB-ENET. It also describes how to connect the GPIB-ENET to a Macintosh computer  
or local Ethernet network, switch on the GPIB-ENET, and power on your system.  
Configure the Hardware  
The GPIB-ENET is shipped from the factory with either a 100 to 120 VAC or a  
220 to 240 VAC power supply. Before you configure your GPIB-ENET, verify that the  
voltage rating listed on the bottom of the box matches the voltage that is supplied in your  
area.  
Warning: Operating the GPIB-ENET at any voltage other than the one specified  
could damage the unit. Replacement fuses must be the proper type and  
size. Refer to Appendix A, Hardware Specifications, for fuse  
specifications.  
Determine Network Addresses  
The Internet Protocol (IP) address is the address that TCP/IP-based networks use to route  
information to the appropriate network and host. When you first install a GPIB-ENET in  
a network, or if the IP address for the GPIB-ENET changes, you must configure the  
IP address for the GPIB-ENET.  
The IP address is not the same thing as the Ethernet address. All devices on an Ethernet  
network are assigned a physical address, which is the Ethernet address, so that they can  
communicate with each other. The Ethernet address of each GPIB-ENET is printed on  
the bottom panel identification label.  
You should see your network administrator to obtain an IP address that is valid for your  
network. Your network administrator can also tell you whether the GPIB-ENET should  
have its IP address configured from the network (dynamic configuration) or with the  
IPassign utility (static configuration). Dynamic configuration is provided by the  
Ethernet Reverse Address Resolution Protocol (RARP). This protocol allows other  
devices on the network to configure the GPIB-ENET with an IP address. See the section  
Select the Method for Configuring the IP Address, later in this chapter, for information on  
selecting the IP address configuration method.  
Make a note of the IP address that you use when configuring your hardware, because you  
must enter the IP address when you install the NI-488.2 software.

Hardware Configuration and Installation  
Select the Operating Mode  
Switch 8 selects the Extended Factory Test mode and should remain OFF for normal  
operating mode. When this switch is ON, the GPIB-ENET performs extended tests  
which require special connections to the GPIB and Ethernet ports. Without these  
connections, the GPIB-ENET cannot pass the extended factory tests.  
Switch 7 selects the Update EEPROM mode and should remain OFF for normal  
operating mode. The firmware controlling the GPIB-ENET is stored in an electrically  
erasable memory. When this switch is ON, you can reprogram the firmware memory  
from the Ethernet network using the Updateutility. Refer to Appendix B, Utilities, for  
more information.

Switch 6 indicates how the GPIB-ENET is configured with its IP address when it is  
powered on. When you first install a GPIB-ENET in a network, or if the IP address  
changes, this switch should be OFF, indicating that the IP address needs to be configured.  
When Switch 6 is OFF, the method of configuring the IP address depends on Switch 5.  
Once the GPIB-ENET receives its IP address, it stores the address in nonvolatile  
memory. After the IP address is stored, place Switch 6 ON so the GPIB-ENET refers to  
the stored IP address and does not wait to be configured with an IP address each time it is  
powered on.  
Switch 5 selects the method by which IP addresses are configured in the GPIB-ENET.  
When Switch 5 is OFF, the GPIB-ENET issues RARP requests each time it is powered  
on. The GPIB-ENET continues to issue RARP requests until a valid RARP reply is  
received. If Switch 5 is ON, the GPIB-ENET does not issue RARP requests. Instead,  
you must use the IPassign utility to configure the IP address in the GPIB-ENET. In  
most networks, the GPIB-ENET can use RARP to have its address dynamically  
configured; however, there are some networks which, for security or other reasons, do not  
use RARP. In this case, you must use IPassign. Refer to Appendix B, Utilities, for  
more information on IPassign. If Switch 6 is ON, the setting of Switch 5 is irrelevant.  
Set the Ethernet Port Configuration  
In addition to a 15-pin AUI connector, your GPIB-ENET has either a 10Base-T Ethernet  
connector or a coax Ethernet connector. Use the slide switch to select the Ethernet port  
the GPIB-ENET uses. Depending on which version you have, National Instruments  
configures the GPIB-ENET to use either the 10Base-T port or the coax port for data  
transmissions, as shown in Figure 2-2.

Hardware Configuration and Installation  
Step 2. Switch on Your GPIB-ENET  
Power on your GPIB-ENET. The POWER LED should come on immediately. The  
READY LED should flash while it completes its power-on self tests. When all the tests  
complete successfully and the IP address is assigned, from either nonvolatile memory or  
the network, the READY LED remains steady, indicating that the unit is ready to  
operate.  
If the POWER LED does not come on immediately or the READY LED continues to  
flash after the IP address should have been assigned, recheck all connections and switch  
settings, and retry the power-on sequence. If the READY LED still does not become  
steady after the IP address should have been assigned, refer to Appendix C, Customer  
Communication, fill out the technical support and configuration forms, and contact  
National Instruments for technical support.  
When the READY LED remains steady, continue with Chapter 3, Software Installation  
and Configuration.

Installation Verification and Troubleshooting  
READY LED Signaling  
The READY LED has several purposes on the GPIB-ENET. When you first power on  
the GPIB-ENET, the READY LED flashes while it completes its power-on self tests.  
When all the tests complete successfully and the IP address is assigned, from either  
nonvolatile memory or the network, the READY LED remains steady, indicating that the  
unit is ready to operate.  
During operation, there are times when the READY LED might flash again. The first  
time occurs after upgrading the EEPROMs, when the GPIB-ENET reports status on the  
operation. Refer to Appendix B, Utilities, for more information. At other times, the  
GPIB-ENET alerts you of internal errors. For assistance in correcting this problem,  
please record the pattern that the READY LED flashes, and contact National  
Instruments.  
Note:  
By recording the READY LED status messages before calling National  
Instruments, you can save yourself time, and the GPIB Product Support  
Department can answer your questions more accurately and efficiently.  
Do not switch off power to your GPIB-ENET before recording the flashing  
READY LED pattern.  
READY LED signaling can report up to 100 different errors. The errors are numbered  
from 0 to 99 and are reported through sequences of READY LED flashes.  
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 ON, one second OFF. These long flashes represent the digit in the tens  
column. There can be one to ten long flashes, which represent digits 0 through 9. For  
example, one long flash represents a 0 in the tens column, two long flashes represent the  
digit 1 in the tens column, and ten long flashes represent a 9 in the tens column.  
Step 2. Count the Short Flashes  
The long flashes are followed by shorter flashes; each lasting about one-fifth of a second.  
These short flashes represent the digit in the ones column. Again, there can be one to ten  
flashes which represent the digits 0 through 9. For example, one short flash represents  
the digit 0 in the ones column, two short flashes represent the digit 1 in the ones column,  
and ten short flashes represent a 9 in the ones column.  
Using this method, the READY LED flashes the following sequence to represent status  
message 11.  
<three seconds OFF> <two long flashes> <two short flashes> <three seconds OFF>…  
The READY LED flashes the following sequence to represent status message 30.  
<three seconds OFF> <four long flashes> <one short flash> <three seconds OFF>…

Installation Verification and Troubleshooting  
My driver is not communicating with the GPIB-ENET. What should I do?  
Make sure that DIP Switch 7 is set to OFF. If Switch 7 is OFF and the driver still cannot  
communicate with the GPIB-ENET, make sure that the Ethernet Port Configuration slide  
switch is in the correct position for your network connections.  
My I/O worked with a board interface, but it times out when I use the GPIB-ENET  
interface. What should I do?  
Network communication is slower than straight cable communication. You might need  
to raise the Timeout value on your NI-488 Configconfiguration screen.  
The Update utility returns the message "Bad checksum." What should I do?  
Run the Update utility again. Your imagefile might be corrupted. If the same message  
appears when you run the utility again, try reinstalling your NI-488.2 software and then  
running the Updateutility again.  
I powered off my GPIB-ENET before recording the flashing READY LED pattern.  
What should I do?  
Try to duplicate the error before calling National Instruments for assistance. Recording  
the READY LED pattern is not critical to the operation of your GPIB-ENET, but it saves  
you time and helps Product Support to diagnose the problem more quickly and  
accurately.  
What do I do if I have installed the NI-488.2 software and now my Macintosh  
crashes upon startup?  
Try changing the name of the NI-488 INITto ZNI-488 INIT. Because INITs load  
in alphabetical order, the ZNI-488 INITwill load last, preventing possible corruption  
from INITs that load after it. If changing the name of the NI-488 INITdoes not solve  
the problem, another INIT file might have a conflict with the NI-488 INIT. Try  
removing some of your other INIT files. You can store them in a temporary folder, in  
case you need to reload them later. If you are using System 7.5 or later, you can use the  
Extensions Managercontrol panel to disable certain extensions and control panels.  
My system has been crashing since I switched to a Quadra computer. What should  
I do?  
This problem was associated with some versions of the NB Handler INIT. Upgrade  
to the NI-488 INITto resolve this situation.

Appendix B  
Utilities  
This appendix contains information on the IPassignand Update utilities for the  
GPIB-ENET.  
IPassign Utility  
If your network does not have RARP capabilities, you can use the IPassignutility  
to configure the IP address for the GPIB-ENET. Before using this application, make sure  
that you know the Ethernet address of the GPIB-ENET, which is listed on the bottom  
panel of the box, and the IP address that has been selected for the box. The IP address  
should be a unique IP address not yet used within your network or domain. If you do not  
know the IP address, see your network administrator. Once you configure the IP address,  
it is stored in nonvolatile memory in the GPIB-ENET.  
You should run the IPassignutility only when the box is new or when you decide to  
reconfigure your network in a way that changes the IP address of the GPIB-ENET.  
Because of protocol limitations, this utility must be run from a Macintosh with an  
Ethernet port. This utility does not work from LocalTalk.  
To run IPassign, follow these steps after you have connected the GPIB-ENET to the  
network and installed the NI-488.2 software.  
1. Make sure that you configure the DIP switches properly. Switch 6 should be OFF,  
indicating that you are going to configure a protocol address from the network.  
Switch 5 should be ON, indicating that you are using IPassignto configure the  
IP address. Switches 8, 7, and 4 through 1 should all be OFF.  
2. Power on the GPIB-ENET.  
3. Change to the folder that contains the NI-488.2 distribution files.  
4. Execute the IPassignutility, which is located in the Ethernetfolder.  
a. Select an Ethernet interface to use by clicking on the appropriate dialog button.  
b. Enter the IP address that has been selected for the box. Enter the IP address in

c. Enter the physical Ethernet address for the GPIB-ENET. This is the address  
shown on the identification label on the bottom panel of the GPIB-ENET. Enter  
the Ethernet address in standard notation, which is six hexadecimal numbers  
separated with colons.

Utilities  
Appendix B  
d. IPassign constructs 10 reply packets and sends them across the local  
Ethernet. When the GPIB-ENET successfully receives its IP address, the  
READY LED remains steady. As long as the READY LED is flickering, the  
address has not been configured.  
Because the reply packets do not form a guaranteed delivery protocol, it is  
possible (though extremely unlikely) for all 10 packets to get lost in the network  
and for the GPIB-ENET not to receive any of them. In this case, rerun the  
utility until the GPIB-ENET successfully receives its new IP address.  
5. When the READY LED remains steady, power off the GPIB-ENET and set DIP  
Switch 6 to the ON position. With the switch in this position, the GPIB-ENET  
powers on at the IP address configured in Step 4, which is stored in nonvolatile  
memory. If Switch 6 is ON, the position of Switch 5 does not matter.  
6. Power on the GPIB-ENET and wait for the READY LED to come on and remain  
steady.  
Update Utility  
If you have received your NI-488.2 software as an update to your current GPIB-ENET,  
you need to update the firmware in the GPIB-ENET. Electrically Erasable  
Programmable Read Only Memory (EEPROM) stores the firmware that controls the  
GPIB-ENET. You can use the Update utility to upgrade the firmware in the EEPROM.  
The latest firmware file is called GPIBENET_EPROMxx, where xx stands for the latest  
firmware revision number.  
Caution:  
Please read this entire section before attempting to update your firmware.  
If you are directly linked to the Internet, and not just to an isolated network using IP  
protocols, you can contact the National Instruments GPIB Product Support Department to  
update your firmware. If you are not on the actual Internet or you want to update the  
firmware yourself, you can execute Update locally. In either case, pay close attention  
to the GPIB-ENET READY LED, which reports important status codes.  
Although you should update your firmware as needed, the number of times you can do so  
is limited. Therefore, you should update the firmware only when necessary. Also, notice  
that there is a time period of about two seconds when the GPIB-ENET runs exclusively  
in volatile RAM memory with the EEPROMs erased. If the box loses power during this  
time, it is no longer usable and must be returned to National Instruments for repair. If  
you are not comfortable with this procedure, call National Instruments for assistance.  
Caution:  
Because of the potential loss of EEPROM information, do not attempt to  
update the firmware when your electrical power is in danger; that is,  
during a weather storm or similar situation. Once you have started the  
update process, do not switch off power to your GPIB-ENET until you see  
and record the flashing READY LED pattern.

Appendix B  
Utilities  
The following procedures describe how to update the firmware.  
1. Power off the GPIB-ENET and set DIP switch 7 to the ON position.  
2. Power on the GPIB-ENET and wait for the READY LED light to remain steady  
without flashing.  
3. Execute the Updateapplication, which is located in the Ethernetfolder.  
a. Enter the IP address of the GPIB-ENET in the space provided, and click on the  
Done button to continue.  
b. Select a GPIB-ENET EEPROM file to use as the firmware image.  
After the GPIB-ENET receives the firmware image, the Update utility reports  
the status of the download. At that point, the network connection is closed.  
Therefore, the utility does not report the success or failure of the actual  
EEPROM programming, but only of the transfer of the firmware image.  
c. After the connection terminates, the GPIB-ENET attempts to program its  
EEPROMs. Wait for the READY LED to begin flashing, which signals that the  
procedure is complete. Do not power off your GPIB-ENET before you see and  
record the flashing READY LED pattern.  
If the programming is successful, the READY LED signals a status code of 00,  
signified by one long flash and one short flash. Other patterns are used to  
indicate that the EEPROMs did not program properly. If a pattern other than 00  
is indicated, make note of the flashing pattern before switching off the  
GPIB-ENET, and contact National Instruments for further assistance. Refer to  
the section READY LED Signaling in Chapter 4, Installation Verification and  
Troubleshooting, for more information on recording the flashing pattern.  
4. Power off the GPIB-ENET and return DIP switch 7 to the OFF position.  
5. Power on the GPIB-ENET and wait for the READY LED to remain steady without  
flashing.
