Hello, I am trying to use Labview to control Newport ESP 301.
The communication between ESP 301 to the PC is perfectly fine. But the LabVIEW communication with ESP301 has problems. The device shows up in NI MAX. However, it has a '!' mark below. When I test it with the VISA test panel, it shows:
VISA: (Hex 0xBFFF0015) Timeout expired before operation completed.
Could you please give me some suggestions to solve this problem? I really appreciate any help you can provide.

This instrument does not follow the standard SCPI command set. You will need to read the Command Interface Module on how to communicate with the instrument.

NI-Max defaults to the standard SCPI query command of "*IDN?\n" for external devices. As such, your device does not recognize that instrument query as a valid command/query string and returns the error. This is the reason for the '!' in NI-Max.
