SR400 Labwindows

[Vinit]

Hi all,
   I am totally new to labwindows/labview. I want to control the Two Channel Gated Photon Counter SR400 using labview mainly to record and collect data for long hours. I have connected the Counter to my computer using GPIB cable and Keithley KUSB-488 which provides USB interface for the GPIB card.

  I am using the latest evaluation version of Lab Windows. I have also downloaded the device drivers for SR 400 from the ni website. Now, what should be the next step. How can I communicate with the device.

Thanks in advance.

Hi Vinit,

The instrument drivers that you download from NI.com for Lab Windows/CVI provide the function calls based on the .c and header files. If you open the files in CVI then you will be able to see and use the function calls as you want. It also provides front panels for each function so that you can test them.  The only problem you may run into is getting your device recognized as a resource. Can you run the sr400_init function in CVI or is there an error. Our GPIB instrument drivers are written assuming that the end user has an NI GPIB board. Since you do not there may be some issues getting the device to initialize but the rest should work properly.
