GPIB instrument freezes

[AndreaD]

Hi, 

I'm communicating with a older model of motor controller using USB-GPIB cable. For the most part when I communicate through NI MAX, it's okay, occasionally freezing up. However when I communicate with the same code with LabVIEW, it tends to freeze up more often than it doesn't. Is there a rate/speed issue, or communication issue if the unit I'm controlling is older? The USB-GPIB cable is operating correctly, I had it communicating correctly with another unit. 

Thanks, 

Andrea

Hi Andrea

Could you please be more specific with the model of the Driver, the NI MAX configuration and the LabVIEW code you are using?

Also what do you mean with freeze-up? Do you have to end the LabVIEW process?
