gpib triggering via VISA/CVI

[parigigi]

Hi to all!

I am trying to triggering 5 digital multimeters using LabWindows/CVI 8.0. I am using the USB/GPIB controller Agilent82357A.

I can easily communicate with each instrument, and so I am able to make them waiting for the trigger pulse; but I cannot find a way to communicate with the whole bus.

Anyone can help me?

My problem is that while I am able to communicate with the single devices I cannot communicate with the bus!

I have started a VISA session with the command viOpenDefaultRM

then have started the communication with the single devices with the command viOpen.

I tried to use viOpen for GPIB::INTFC but i didn't work.

I  don't have understood how to write to the bus!

thanks
