GPIB-ENET/100 for Mac OS

What do I do if I have installed NI-488.2 and now my Macintosh
crashes upon startup?

Try changing the name of the

NI-488 INIT

to

ZNI-488 INIT

. Because

INITs load in alphabetical order, the

ZNI-488 INIT

will load last,

preventing possible corruption from INITs that load after it. If changing
the name of the

NI-488 INIT

does 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. You can use the

Extensions Manager

utility to disable

certain extensions and control panels.

I have a GPIB-ENET. Can I use the GPIB-ENET and GPIB-ENET/100
in the same system?

Yes, this version of NI-488.2 supports systems containing both products as
well as systems containing only one of the two products.

How do I configure my existing GPIB-ENET with this software?

This version of NI-488.2 includes options for configuring both the
GPIB-ENET and the GPIB-ENET/100. Use the utilities in the

Ethernet

folder with the GPIB-ENET, and the utilities in the

Ethernet/100

folder

with the GPIB-ENET/100. For information on configuring the
GPIB-ENET hardware, refer to

Getting Started with Your GPIB-ENET and

the NI-488.2 Software for MacOS

.

I have an application using the GPIB-ENET. Can I replace the
GPIB-ENET with a GPIB-ENET/100?

Yes. You do not need to rewrite your application code to replace
a GPIB-ENET with a GPIB-ENET/100. However, you do need to
configure the GPIB-ENET/100 to have the same network identity as the
GPIB-ENET you are replacing. First, acquire network parameters for the
GPIB-ENET/100 using DHCP or the

NI Ethernet Device Configuration

utility. Then use the

NI-488 Config

utility to remove the GPIB-ENET

information from the

Bus/Device

list and reassociate the same entry with

the IP address for the GPIB-ENET/100. For example, if your application
code refers to the GPIB-ENET as

gpib1

, reconfigure

gpib1

to refer to the

GPIB-ENET/100.
