Issue: Multiple PT104 devices via USB

Post by kaltenba » Mon Jun 15, 2015 9:19 pm

Hello,
I am trying to read 4 PT104 device via USB in LabView. Based on the template and the instruction to daisy chain the interface handle through all device/interface open calls, I am only able to read two devices. There are no errors but the other two devices are not properly addressed.
Could you please advise how to read four PT104 device in a clean way using LabView?

I am using LabView 2013 with the 32bit DLLs on a 64bit Win7 PC

Thank you for your help.
Best regards,
Thomas

Each device will have it's own unique handle, whenever you set up a device or request data you will need to use the devices own handle, so any calls to these functions will need to pull in the correct handle for the device you are looking at.

Daisy chaining the interface handle through all device/interface calls does not sound correct to me. Can you clarify what you mean by this ?
