Re: Working for GPIB

hi,
U can connect 14 instruments at a time.
when u send a command, all the instruments will listen your request,but only one instrument will reposnd to your request,i.e.,u can speak to one instrument at a time.

I have interfaced 8 instruments using VB6.0
I have used agilent GPIB pci card for interfacing from the PC.
I am attaching some sample code understand it first and if u have any doubt mail me at yviswanathbe@gmail.com
