Hello,
I am new to ‘GPIB’, for my project I have to run one application on Windows (os) controlled from an Unix system.
Under Windows (os) I have a C# (VS-2008) application which have to read strings from Unix, windows-pc is installed with NI-GPIB-USB.
When I try to send one string from Unix, the program try to send but it stops after 15sec because of timeout. On Windows side I cannot read any string.
I think the problem is not so complicated for many of you because I am a beginner in GPIB and C#, it will be very helpful if someone can solve it. I am adding some part of my C# code here.
using NationalInstruments.NI4882;
namespace ftt
{
public class ts
{
Device device = new Device(0,11);
Board board = new Board(0);
string mes; bool i = true;
public string dloop()
{
while (i)
{
GpibStatusFlags mask = (GpibStatusFlags.ListenerAddressed);
try
{
board.Wait(mask); // Update gpib status
}
catch (ArgumentException) { MessageBox.Show("A bit set in the mask is invalid"); i = false; }
catch (GpibException) { MessageBox.Show("NI-488.2 driver returns an error"); i = false; }
// Addressed as a Listener
if(board.GetCurrentStatus() == GpibStatusFlags.ListenerAddressed)
{
mes = device.ReadString();
i = false;
}
. . . . .. .. .. ... ...
return mes;
