  • I am using the NI-SWITCH Connect Multiple VI in LabVIEW. This always produces error -1074115640. If I use the NI-SWITCH Connect Single VI, there is no error. Why is this happening?
  • I am using the NI-SWITCH API and I am running into the error below:

Possible reason(s):

Removing this hyphen or invalid character will resolve this error. Refer to How Do I Find or Modify My Device's Name? for instructions.
