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.
