PaulC Posted October 22, 2009 Share Posted October 22, 2009 I'm monitoring 12 channels at 100Hz (4 timers and 8 analog in, at 0.01 s sample time), but every ten or twenty seconds receive the error: C1038 Timing lag, data acquisition stalled. Resetting. Timing: 0.010, Offset: 0.000 I'm on a U6 LabJack, and have USB 2.0. Is this a DAQFactory issue? It seems like the LabJack can acquire at this speed, so I'm suspecting DAQFactory as the culprit in not being able to do this:D If that's true, why can't it? Any tricks?

AzeoTech Posted October 23, 2009 Share Posted October 23, 2009 As it explains in the manual, no software tool under Windows can really reliably achieve 100hz using polling mode (where the software requests the value from the device). This is because of the way Windows does its task switching to make it multitasking. If you really know what you are doing, there are tricks that could maybe get it to work, but in general, if you want to go faster than 50hz (timing = 0.02) then you should use the stream mode of the LabJack.

PaulC Posted October 23, 2009 Author Share Posted October 23, 2009 Thank you. I will look into using streaming mode with DAQFactory. Link to comment Share on other sites More sharing options...
AzeoTech Posted October 24, 2009 Share Posted October 24, 2009 Its all explained, with samples, in the DAQFactory - LabJack application guide. Link to comment Share on other sites More sharing options...
