Hi,
I am programming in C# and using the RsInstrument_CSharp_Hello_Word_Example for open the communication
with GPIB interface.
I have a problem with a Visa this Resource GPIB0::16::INSTR
It's a RF- Relaise Matrix
I must only send this command: R1R2R3R4R5R6
When I check command with NiMax its all ok but the problem is in C#. The exception error is "viReadSTB() - Timeout occured"
my simple source is above.
I tried changed contructor flag but not found nothing soluting or option.
With a NI/IO trace I see that, I think that the problem is that when open the visa resource the matrix hardware not accept the standand control *CLS and STB
There is a way for avoid the extra control and open only the resource?
Thanks for help.
