Compliance
FCC/Canada Radio Frequency Interference Compliance*
Determining FCC Class
The Federal Communications Commission (FCC) has rules to protect wireless communications from interference.
The FCC places digital electronics into two classes. These classes are known as Class A (for use in industrialcommercial locations only) or Class B (for use in residential or commercial locations). Depending on where it is
operated, this product could be subject to restrictions in the FCC rules. (In Canada, the Department of
Communications (DOC), of Industry Canada, regulates wireless interference in much the same way.)
Digital electronics emit weak signals during normal operation that can affect radio, television, or other wireless
products. By examining the product you purchased, you can determine the FCC Class and therefore which of the two
FCC/DOC Warnings apply in the following sections. (Some products may not be labeled at all for FCC; if so, the
reader should then assume these are Class A devices.)
FCC Class A products only display a simple warning statement of oneparagraph in length regarding interference and
undesired operation. Most of our products are FCC Class A. The FCC rules have restrictions regarding the locations
where FCC Class A products can be operated.
FCC Class B products display either a FCC ID code, starting with the letters EXN,
or the FCC Class B compliance mark that appears as shown here on the right.

GPIB-ENET/100 Hardware Overview
The GPIB-ENET/100 high-speed interface controls GPIB instruments
across Ethernet networks. You can use the GPIB-ENET/100 to access
remote test equipment from anywhere in the world via TCP/IP protocols on
10Base-T and 100Base-TX networks. By incorporating a new architecture,
100Base-TX Ethernet, and HS488, the GPIB-ENET/100 delivers
performance comparable to that of plug-in boards.
The GPIB-ENET/100 automatically detects if the available network is
10Base-T (10 Mbits/s) or 100Base-TX (100 Mbits/s) and transmits at
the highest available speed.

Feature Overview
Chapter 1Introduction
You can use either the Dynamic Host Configuration Protocol (DHCP) or
a simple Ethernet configuration utility to configure the GPIB-ENET/100
without the need for any dip switches or jumpers. Installation options
include rack mounting, DIN rail mounting, wall mounting, and stackable
stand-alone use. You can stack the unit with other GPIB-ENET/100 units
and additional National Instruments products including the ENET-232
Series and ENET-485 Series serial controllers.
For more information about hardware specifications, refer to Appendix C,
Specifications.
With the GPIB-ENET/100, you gain all the features inherent in a
networked device: fewer cabling distance restrictions, device sharing,
and communication with devices throughout the Internet.
In a GPIB application, you are restricted to the distance limitations of the
GPIB specification. However, you can overcome these restrictions because
the GPIB-ENET/100 uses Ethernet, and can add an unlimited distance to
your application simply by utilizing the distances available to you by using
a networked device. Because the GPIB-ENET/100 uses standard Internet
protocols, you can exploit the Internet to communicate with your GPIB
instruments throughout the world.

NI-488.2 Overview
The NI-488.2 software for Mac OS is a comprehensive set of programs
and drivers. It simplifies the job of programming the GPIB-ENET/100 to
function as an IEEE 488.2 (GPIB) Controller with complete
communication and bus management capabilities.
Flashes rapidly at start-up while performing self
tests and when acquiring network parameters.
A steady yellow state indicates the box is ready
for operation. Slow flashing pattern indicates an
error occurred.
Indicates the GPIB-ENET/100 detected a twisted
pair (10Base-T or 100Base-TX) link. The color
indicates the connection speed. If yellow, the speed
is 10 Mbits/s. If green, the speed is 100 Mbits/s.
Indicates the GPIB-ENET/100 is transmitting to
the Ethernet network.
Indicates the GPIB-ENET/100 is receiving
Ethernet network traffic.
Indicates the GPIB-ENET/100 is configured as a
GPIB Talker.
Indicates the GPIB-ENET/100 is configured as
a GPIB Listener.
NI-488.2 also includes a GPIB interactive control utility; the Macintosh
Programmer’s Workshop (MPW) C, THINK C, and Metrowerks
CodeWarrior C language interfaces; and a shared library for
C programmers developing applications for the PowerPC platform.

Time-Saving Development Tools
Your kit includes the NI-488.2 software for Mac OS. In addition, you can
order LabVIEW from National Instruments. LabVIEW includes
instrument driver libraries that make it easier to communicate with your
GPIB instruments.
LabVIEW is a graphical programming environment you can use to acquire
data from thousands of different instruments, including IEEE 488.2
devices, VXI devices, serial devices, PLCs, and plug-in data acquisition
boards. After you acquire raw data, you can convert it into meaningful
results using the data analysis routines in LabVIEW. The LabVIEW
instrument drivers reduce software development time because you do
not have to program the low-level control of each instrument.
If you already have LabVIEW and want to use it with your
GPIB-ENET/100, refer to your product documentation for information
about GPIB I/O functions. For ordering information, contact National
Instruments.
Complete the following steps to install your GPIB-ENET/100.
Step 1. Record the Serial Number, Ethernet Address,
and Default Hostname
When you configure the GPIB-ENET/100 for use on your network, you
will need to differentiate it from other network devices. Every product has
a unique serial number, Ethernet address, and default hostname.
1.Locate the serial number, Ethernet address, and default hostname on
the GPIB-ENET/100 baseplate label, as shown in Figure 2-1.
2.Write down this information and keep it available so you can refer to
it later as you configure the GPIB-ENET/100.
Note
The Ethernet address is not the IP address. All devices on an Ethernet network
are assigned a unique physical address—the Ethernet address—so they can communicate
with each other.

If you do not have an Ethernet cable, as listed in the What You Need to Get Started
section of Chapter 1, Introduction, contact National Instruments for ordering information.

To connect your cables, complete the following steps:
1.Connect one end of your Ethernet cable to your GPIB-ENET/100.
Connect the other end of the Ethernet cable to your Ethernet network.
Make sure you comply with all IEEE 802.3 cabling restrictions.
2.Because AC outlets vary throughout the world, your kit includes a
power cord that meets your local requirements in addition to a power
supply. Figure 2-3 shows how to hook up your power cord and
power supply.
