Why do I have a Time Drift in my Synchronized DAQ-CAN Application? If you are using the standard examples for synchronization between a DAQ and a CAN board, sometimes there are drifts between the signals, so it seems that the synchronization does not work correctly. This behavior is related to the DAQ timebase which is used as the master timebase for both URL: http://digital.ni.com/public.nsf/allkb/B846715D4A0586BE86257115005A4AA9

Incorrect Analog Input Readings When Using a DAQCard Windows NT I am using a DAQCard-500, 516, or 700 on Windows NT. The analog input readings differ significantly from the applied voltage. Also, when I open the Measurement & Automation Explorer (MAX), the Serial Number for the card shows up as '0'. URL: http://digital.ni.com/public.nsf/allkb/6B7BD73E3859C93386256B3A005BAB79

Why Does the Counter Source Sink 120mA When the Computer is Powered Off? I have an E Series MIO device with a TTL signal connected to the counter's SOURCE input. When I switch off the computer, I measure a sink current of approximately 120mA on the source of the counter. When I disconnect the power cable to the PC, I do not have this problem.

Why Does My Floppy Drive Light Turn On when Reading from Channel 16? I am running NI-DAQ 4.9.0 on a Windows 95 machine. When I read from Channel 16 on the AT-MIO-64E-3, the floppy drive light turns on. Reading from other AI channels does not cause this problem. Why is the light on when I access Channel 16?

After Power Cycling the DAQPad-1200 with LabVIEW Open, I Get Bad Data when I Run a VI If I power cycle my DAQPad-1200 while LabVIEW is open, then I get bad data when I subsequently run my VI. I have to exit LabVIEW and re-run the configuration utility in order to reset the parallel port. Then I can reopen LabVIEW and get good data. How can I avoid this?
