what is defined as the proper initialization of a GPIB controller prior to issuing ibdev?

CraigByrd,

I am not sure that I understand your question.  ibdev asks for the board index, primary address, secondary address, timeout, EOI mode, and End Of String mode/bye as inputs if that is what you are asking.  More information can be found in the 488.2 help menu, which can be found in your start menu at Start » All Programs » National Instruments » NI-488.2 » NI-488.2 Help.

For example, C:\Program Files\National Instruments\NI-488.2\Bin\Sample.txt demonstrates device level commands.  I am curious what are the board level commands (IFC, ibsre) one might send from the controller prior to running the device level commands upon startup of an application.

On a side note, where does one find the proper versions of (gpib-32.obj,ni4882.obj) and (decl-32.h or ni4882.h) to use with the Visual Studio 2008 development environment.

I have found various .h and .obj files in C:\Program Files\National Instruments\Shared\ExternalCompilerSupport\C\lib32 but would like to know which are used where (in terms of various Visual Studio environments (6.0, 2005, 2008)

CraigByrd,

In many cases, ibdev may be the first command used.  For example, if you take a look at the simplescope example at C:\Documents and Settings\All Users\Documents\National Instruments\NI-488.2\Examples\Standard C\ScopeSimple\Simple.c, you can see that the first line of code in the main function is an ibdev call.
