Dear All...
In my project, I need to control two GPIB Instrument (prober and meter) which connected with the same GPIB Card in my PC.
when I Initial Prober, I get two handles GHostUD_P and GDevUD_P,
then I Initial Meter, I get two handles GHostUD_M and GDevUD_M,
My Question is I need to Initial GPIB card twice!? or can only initial once..(use the same GHostUD...)
if I want to Disconnect Prober but still use Meter...
so I use ibonl (GHostUD_P ,0) and ibonl (GDevUD_P, 0) two command, then the gpib card has been set to off line...
Does it effect the Meter's Communication!? if I use different GHostUD handle, dose it work!?
thanks a lot...

Hi,
Thank you for posting on National Instrument's forum.
What's the model of this GPIB Card?
The purpose of GPIB, is to communicate with several device.
