gpib won't communicate

[burchiantidavid92]

hi all.

I have 2 identical usb-GPIB adapter, and two different PC with the same acquisition software written in LabView, in the first machine, i can use both usb-GPIB interface with no problems.

on the second PC, the first interface works perfectly, the second one, instead, is recognized perfectly in windows device manager, but when i try to communicate with my instruments, the software says "oscilloscope was not found, check the cable or the instrument", what can i try??

thanks for the support. David

Hello,

do you have all the needed drivers also in the second PC?

Which software gives you the error message? Is the LV application? You should check out which condition creates that error.

Kind regards

hello and thanks for the replay, i think the drivers are installed correctly, cause the second usb-gpib adaptor works perfectly on both pcs. if i work on the pc that have the problem with one usb-gpib adaptor all works perfectly, with the second nothing works, all my labview applications (flux probe analysis, partial discharge logger, etc) says unable to communicate with the instrument, (and with all instruments i try to use: oscilloscopes, multimeters etc.) it seems that the interface is faulty and won't to communicate over gpib bus, but on the second pc it works perfectly.. PS: ready led appear on the interface ever with all configurations.

 Hi David, 

what about posting on italian forum? I think it would be way too better since I am not able to understand your point.

If you are getting troubles with the interface on both the PC the problem is for sure of the interface.

Kind regards.
