LabJackSupport Posted July 30, 2015 Share Posted July 30, 2015 Make sure you are only running 1 program (1 copy of DAQFactory) that might be talking to the U12. That error usually means some other program has claimed the U12. Is the error intermittent, or once you get the error can you no longer talk to the U12? Run LJtest (with no other programs running) and make sure it reports that you are using U12 version 1.22. Note that if you want LJtest to pass all tests you need to have nothing connected to the U12 except for the USB cable. Are you using stream or burst mode, or just channels in the DF Channels list with normal command/response timing? If you make a simple new DF CTL from scratch that simply acquires AI0 at a 1.00 second interval, does it have the same issue? Link to comment Share on other sites More sharing options...
