GPIB-ENET for MacOS
Chapter
2
Hardware Installation
and Configuration
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.
Caution:
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
