IVI driver

[PhaniChillara]

Hi, I am using chroma 63600-5 DC electronic load, and developing an application using LabVIEW 2011. I have downloaded drivers from NI website. Which is IVI Type. And the communication with the instrument is USB. It is recommended to install LV VISA 3.0 above runtime engine in PC. Presently I have 5.0 version.

My problem is when I am using the ivi drivers initialize vi. With resource name 'USB0::0x0A69::0x083E::636005000213::INSTR' (got from VISA resource finder) its showing a error. "Error code: -1073807298 , Source: chr63600 Initialize.vi<ERR> Driver Status:  (Hex 0xBFFF003E) Could not perform operation because of I/O error."

when I use GPIB I am not getting any error.

what is the resource name I should give while using USB communication.

Thanks is advance

For USB instruments in general I have found the easiest way to access them is:

Start the Measurement and Automation Explorer (MAX) 

Search for instruments specifically USB

Once the instrument is found go to it's VISA properties tab and create a VISA Alias (name it something like Chroma_DC_Load)

Use the alias you just created as the VISA resource in your LabView code.

Instead of "USB0::0x0A69::0x083E::636005000213::INSTR" use "Chroma_DC_Load" as the VISA resource

Are you selecting the IVI logical name you created in MAX? Do you have the latest version of the IVI Components installed?

Sorry, it's the IVI Compliance package.
