Issue Details

I have a third party device I am trying to communicate with over USB via NI-VISA. I get error at the Visa Read: -1073807313 "VISA: (Hex 0xBFFF002F)". Why?

Solution

This error is sometimes associated with the communication method employed by NI-VISA. To remedy the issue, try right clicking the VISA Read function and selecting Sychronous I/O Mode >> Synchronous.

Additional Information

​When a VISA read is executed asynchronously, the function returns before the device finishes reading the data. VISA then periodically check to see whether it has finished reading all data into the device's buffers. If yes, an event is triggered to signal that the read has finished.
