Using the NI-VXI/NI-VISA

Software

This chapter discusses programming information for you to consider when

developing applications that use the NI-VXI/NI-VISA driver.

After installing the driver software, you can begin to develop your

VXI/VME application software. Be sure to check the

README file for the

latest application development notes.

You must run

resman each time the computer or chassis power is cycled so

that your application can access devices in the VXI or VME chassis.

The NI-VXI software was designed for use in VXI systems. Because VXI

is a superset of VME, you can also use the NI-VXI functions as a

comprehensive set of programming tools for VME systems. Refer to the

NI-VXI User Manual and the NI-VXI online help for overviews of NI-VXI

and detailed descriptions of the NI-VXI functions. The user manual is

available in the

NIVXI

/manuals directory (where

NIVXI

refers to the

actual location where you have installed the NI-VXI software). Use the

Adobe Acrobat Reader program to open and navigate through this manual.

Notice that the function descriptions indicate whether they apply to VXI

only or both VXI and VME. The following function classes apply only

to VXI:

• Commander Word Serial Protocol functions

• Servant Word Serial Protocol functions

• VXI Signal functions

• VXI Trigger functions

Refer to the NI-VISA User Manual to learn about VISA and how to use

it in your system. The NI-VISA online help describes the attributes,

events, and operations you can use in NI-VISA. The user manual is

available in the

VXIpnp

/linux/NIvisa/Manuals directory. Use the

Adobe Acrobat Reader program to open and navigate through this manual.
