“The Current Instrument Model “” Is Not Supported by This Driver Version” Error or -1073807339 Timeout Error When Using NHR 9400 LabVIEW Driver

Issue Details

When trying to use the LabVIEW NH Research 9400 Series driver library's NH Research 9400 Series Basic Example.vi example, I receive the error below:

The Current Instrument Model “” Is Not Supported by This Driver Version

Sometimes, I will instead receive the following error when using the NHR driver library VI's:

VISA: (Hex 0xBFFF0015) Timeout expired before operation completed.

I am using a compatible NHR 9410/9420/9430 model, how can I resolve these errors?

Solution

These errors are typically seen when using the "TCPIP::IPADDRESS::5025::SOCKET"  VISA Resource Name implementation.  Instead, use the "TCPIP[board]::host address[::LAN device name][::INSTR]" VISA Resource name implementation.

For example an appropriate resource name would be "TCPIP0::192.168.0.149::inst0::INSTR" as this tells NI-VISA that it needs to use the VXI-11 protocol when communicating with the NHR equipment and this is what our LabVIEW driver is designed to use.

If you define the NHR hardware in NI MAX as a VXI-11 instrument, you can also use the Alias name assigned to the instrument instead of the above naming format.
