Connecting Northern Digital Instrument Ethernet Motion Capture System

[CathyAbes]

I am currently trying to connect a Polaris Vega VT (from Northern Digital Instruments) via ethernet to Labview. In VISA Test panel, I have added the instrument and it shows it is present, however it is unable to communicate. In VISA Test Panel I have tried to send an *IDN\r command but receive this error. 

When using the driver provided for this instrument (not by NDI, and updated last in 2014) I recieve the following error:

With this being the sub vi with the issue:

I have scoured the internet and also emailed NDI themselves, but they have said they do not support Labview - is there any possibility in connecting the device? 

Thank you in advance for any information!

The *IDN\r only works if the instrument supports SCPI. 

Based on my quick reading on Polaris Vega VT, it does not support SCPI. NDI develops their own library and API. You can try to download the SDK from NDI Software Packages for OEM Tracking Solutions and use the API via Call a Dynamic Link Library (DLL) from LabVIEW

Hi ZYOng, 

Thank you for your reply. That makes sense why I am receiving an error then. 

Do you know why I would be getting an error in Property Node 1?

No idea. You should reach out to the developer of this library.
