Error -1073807202 occurred at an Property Node(arg 1) in VISA Configure Serial Port(Instr).vi->Continuous Serial Write and Read.vi

Solution

Please follow the below steps to resolve the issue.

1. Install the latest NI-VISA driver from the driver website and restart the PC.
2. Open and run the VI again. The error message should not appear. If other drivers needed, see: Installation Order for Multiple NI Hardware and Software Products  to ensure the drivers are installed in the correct order.

If you already have NI-VISA installed, check the version of NI-VISA is compatible with your version of LabVIEW:  NI-VISA and LabVIEW Version Compatibility.

Additional Information

The evaluation version of LabVIEW does not install the NI-VISA drivers, but it will install the function palettes for the NI-VISA functions. 

If you are experiencing this issue while using a FieldPoint RT controller, please contact National Instruments for technical support.
