Hi Sandeep,
Make sure that you are using the correct syntax of the URL connection (dstp://[computer name or IP of DS server]/[name of data item]). I normally use the standard URL "dstp://localhost/data" when the DS server is running on the same machine.
I was able to reproduce the 1182 error by specifying the URL connection as "dstp:/localhost/data" (missing "/").
By the way, the "slide" indicator in the "DS Read Data.vi" has has a transparent slide, so you would not be able to see if any data is transferred. Use a new slide instead.
