PICO DrDAQ USB Parallel Port setting for labview 8.2

[100785]

Hi,

I have a PICO DrDAQ card (parallel port) and by using USB Parallel Port  (USB)connect to the laptop, and i already install this software. I can run DrDAQ with PicoScope(DrDAQ software) and can produce a result, but when i try to run it in LabVIEW 8.2 there's no result generated from it. Furthermore, i had check through the device manager (in My Computer=>System Properties) and prompt to see the Pico parallel port within the USB controllers. Therefore, i would like to know is there any setting i need to perform so that the problem can be solve.
Thanks.

Hi

On their website, Pico supply LabVIEW drivers for their products. Have you downloaded the driver for the DrDAQ from here?
You do have an added complication in that you are using a parrallel to usb converter which could cause the driver not to function properly. If you cannot get any measurements after installing the LabVIEW driver can you let me know the model of usb converter you  are using.

Hi,

Thanks for your reply. Ya, I have already download the driver and installed it, but i also cannot get any measurement in the LabVIEW 8.2. The usb converter i using is http://press.picotech.com/pr/en/usb-adaptor.html

Therefore, i would like to know is there any setting i need to perform so that the problem can be solve.

Thanks.

Hi

I have downloaded and installed the driver to examine it although as I do not have the hardware I cannot test it. Could you please tell me how you are setting up your call to the driver dll. It does not look like it is too clomplex you just need to make sure you are setting up connection to the correct port. 'draq_example.vi' that installs with the driver tells you how to set up the port: Ports 1 for LPT1, 2 for LPT2 etc, 101 for USB port 1, etc. I also noticed that before the driver installed it asked me to specify the port the device would be used on. Does the port you set on installation match with the port you are now using?

Hi,

Thanks for your reply. Ya before the driver installed, i specify the USB port for this device to used on and after that i set it to port 101 (for USB) in the LabVIEW.

and the programming is on the attach file.

thanks.
