Overview
If your Model V743 VXI controller is to be a node in an HP-UX cluster, and
it has not yet been installed and con gured according to the procedures in the
Installation Guide for the Model V743 VXI controller, see \Con guring the
Controller" in Chapter 3 before proceeding.
This chapter describes the VXIbus default values and how to change these
values using the utilities provided with the HP Standard Instrument Control
Library (SICL). SICL is an I/O library that comes with your Model V743
VXI controller. You can use SICL for communication with your VXI
SCPI-compatible instruments. Install SICL according to the instructions in the
4
HP SICL User's Guide for HP-UX . If you have an application other than HP
SICL, see your application's documentation for information on changing the
VXIbus con guration.
Description of HP SICL
SICL is a modular instrument communications library that works with a
variety of computer architectures, I/O interfaces, and operating systems.
Applications written in C or C++ using this library can be ported at the
source code level from one system to another without, or with very few,
changes.
SICL uses standard, commonly used functions to communicate over a wide
variety of interfaces. For example, a program written to communicate with
a particular instrument on a given interface can also communicate with an
equivalent instrument on a di erent type of interface. This is possible because
the commands are independent of the speci c communications interface.
SICL also provides commands to take advantage of the unique features of
each type of interface, thus giving the programmer complete control over I/O
communications.
