Introduction Chapter 1

The Back Panel Switches

The GPIB-ENET has a 2-position slide switch and an 8-bit DIP switch that you use to configure the operating characteristics of the box. These switches are located on the back panel of the GPIB-ENET, as shown in Figure 1-3.

The identification label lists various information about the GPIB-ENET, including the part number, hardware revision number, and serial number. It also lists the unique

Ethernet address that was assigned at the factory.

The last line on the identification label lists the AC input voltage (100 to 120 V or

220 to 240 V), the frequency, the current, and fuse information.

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.
