Chapter 236

Interface Check Using NI-488.2 and C++

This example uses the NI-488.2 library to verify that the GPIB connections and interface are

functional. Launch Microsoft Visual C++ 6.0, add the required files, and enter the following

code into your .cpp source file.

The following program example is available on the ESG Documentation CD-ROM as

niex1.cpp.

// ***************************************************************************************

// PROGRAM NAME: niex1.cpp

// PROGRAM DESCRIPTION: This program verifies that the GPIB connections and

// interface are functional.

// Connect a GPIB cable from the PC GPIB card to the signal generator

// Enter the following code into the source .cpp file and execute the program

// ***************************************************************************************

#include "stdafx.h"

#include <iostream>

#include "windows.h"

#include "Decl-32.h"

using namespace std;

int GPIB0= 0; // Board handle

Addr4882_t Address[31]; // Declares an array of type Addr4882_t

int main(void)

{

int sig; // Declares a device descriptor variable

sig = ibdev(0, 19, 0, 13, 1, 0); // Aquires a device descriptor

ibclr(sig); // Sends device clear message to signal generator

ibwrt(sig, "*RST", 4); // Places the signal generator into a defined state

// Print data to the output window

cout << "The signal generator should now be in REMOTE. The remote indicator"<<endl;

cout <<"annunciator R should appear on the signal generator display"<<endl;

return 0;
