Trouble reading data from GPIB instrument using VISA

[Cors]

Hello, I am having trouble with reading data from a GPIB instrument in LabVIEW. It appears that the data that is returned from VISA read is incorrect. (I used NI Spy to verify what it should be and what I get, they are different) The odd thing is that when I use the VISA interactive control utility to get the data, it works perfectly. Is there some sort of VISA property that I need to set to get it to work right? Writing to the device seems to work correctly. If you need more info, please e-mail me @ adeboer@natc-ht.com Thanks in advance!

What exactly do you mean when you say the data you are getting is incorrect? I'm guessing that you are dealing with some sort of data type issue. The VISA Read VI will return a set number of bytes in string (ASCII) format. If you are expecting a different data type, you will have to do some conversion by either using a type cast or string conversion function. The type cast function can be found in the Advanced-> Data Manipulation palette, while the string conversion functions can be found in the String palette.
