I have tried connecting to 2 usb PT-104 devices at the same time but can only connect to the first one. I get an error code 3 when I try to connect to the 2nd one. I am using different handles and I have tried this out in Excel, VB 6 and in VC. I swapped the order of the connection around and still see the same problem.
I have also noticed that one of the units when connected on its own doesn't like to be connected a 3rd time. I can connect, retrieve values and disconnect 2 times but on the 3rd connection it gives me error code 3.
I have updated to USBpt104sdk_r10_1_0_17 and the problem still exists.
Is this a similar issue to Picolog 1000 Fix (PicoLog 1012 and 1216) in the Announcements section?
Has anyone else had an issue connecting to more than one unit at a time?
