E1437A User's Guide
Introduction
Introduction
The programmer's reference is presented as a set of VXIplug&play functions since
this is the primary targeted environment. However, when you performed the setup
for the E1437A, drivers were installed to support various programming
environments as described in the Programing Overview section in the "Using the
E1437A" chapter.
The function descriptions in the programmer's reference are valid for all
environments except ASCII, which is treated in a separate chapter. Be sure to follow
the instructions in the "Getting Started" chapter to assure proper installation and to
become aware of the capabilities of your E1437A software in various programming
environments. You will find the example programs particularly helpful for
programming in different environments.
Many of the function descriptions in the programming reference include several
related functions. You may use the primary function to set all related parameters or
you may use the other functions within the group to set or query a single parameter.
Parameter variables are presented as alphanumeric values which are descriptive and
easy to remember. However, for faster programming you may use the numeric
equivalents for the parameter variables listed at the end of this chapter. The
numeric equivalents are available as popups in the online help, a good reason to use
the online help, if it is available in your environment, rather than this printed
document.
Unless noted otherwise, all functions in this library return 0 if they complete
succesfully and a non-zero integer if they fail. Always check the the return value and
take appropriate action. The error descriptions are listed at the end of this chapter
and in the online help.
