error code -1073807360

[MohanYoungForever]

This error is popping up randomly when trying to communicate to Arduino due to using VISA WRITE . What is the reason for the same please let me know the various workarounds.

Please let me know whether it's a Coding or hardware issue.

An "unknown system error" typically is a hardware issue and not your (VI) coding…

Have you tried to replace the USB cable used for Arduino connection?

Is the Arduino sufficiently powered?

Have you tried communicating with your Arduino using MAX and a VISA Test Panel on the COM port that is connected (via USB) to the Arduino?  Do you still get the "Unknown System Error"?  Are you sure the Ports (on the PC and Arduino), the Cable (USB) and the Arduino are working?
