What is wrong if ibfind returns a –1?
The driver may not be installed correctly or the nodes may not have been
created when the driver was loaded. Try removing and reinstalling
NI-488.2 from the CD, as described in Chapter 2,
Also, the file may require read/write privileges you do not have, or you may
have renamed a device. Make sure that the device names in your application
program match the device names in
ibconf
.
How do I use an NI-488.2 language interface?
For information about using NI-488.2 language interfaces, refer Chapter 4,
. Also refer to the
NI-488.2M Software
Reference Manual

How do I communicate with my instrument over the GPIB?
Refer to the documentation that came from the instrument manufacturer.
The command sequences you use are totally dependent on the specific
instrument. The documentation for each instrument should include the
GPIB commands you need to communicate with it. In most cases, NI-488
device-level calls are sufficient for communicating with instruments. Refer
to Chapter 5,
NI-488M Software Characteristics and Functions
, in the
NI-488.2M Software Reference Manual
, for more information.
What information should I have before I call National Instruments?
Please have the results of the diagnostic test
ibtsta

run
ibic
to try to find the source of your problem.
