Hello,
I am using an Agilent 6675A DC power supply and want to control this through LabVIEW. I have a GPIB to USB converter and have connected the supply to the computer through this cable. On opening up NI MAX, I see COM3 as the USB port which is connected. On running the VISA Test Panel with the *IDN?\n command and clicking query, I get the error ' (Hex 0xBFFF0015) Timeout expired before operation completed.' I have increased the timeout, however I still get the same error. I observe in the 'View Attributes' section, I have an 'Invalid Property Value' for the 'Is Port Connected' attribute. However, on reading few other posts, I understand this can be ignored if the GPIB to USB cable is a non-NI cable as is my case. Since the COM3 port shows up in NI-MAX, could the non-NI cable still be the reason for this error? If not, could someone help me troubleshoot this error?
Thanks
