HI When i run the script "USB-6501 Interactive Control.llb", i have this error "Device identifier is invalid"?If you know another script that drives the "USB-6501" to check its lines, please help me?Best regards

Right now I don't have time to look into the example code, that you provided...!! But why don't you use DAQmx functions OR DAQ Assistant to write a code with whatever functionality you need...??

Hi,

Moderator1983 provide you some interesting suggestion. This KB can help you. Be sure that you don't have space after Dev1 in the front panel.
