Hi everyone, I am new with programming VISA. As part of my first few tasks, I am learning to establish a USB communication with instruments. From the little research I have done so far, I found that there are two classes of USB devices, the USB INSTR and USB RAW. I have no problem communicating with the USB INSTR device I have got. However, I have not been able to establish a successful communication with my USB RAW device. My first attempt to communicate with this device after installing the driver was by means of the NI MAX. ON querying the device to get its identity, the NI MAX returned an error that reads “VISA: (Hex 0xBFFF0015) Timeout expired before operation completed”.
Can anyone please advise me on what to do to clear this read problem? I have attached a snap shot of the NI MAX window showing the error message.
