Trouble Shooting

1. VI shows an error about "/data2".
   1. "/data2" does not get mounted if it is not online when booting up the OS.  There is a way of mounting it manually.  But for now please reboot the OS.
2. VI shows an error about COM/Ethernet/USB communication with a device.
   
   1. Make sure that the device is ON.
   2. Open and close "Instacal" (whose icon is in the taskbar) if the device is MCC E-TC.
   3. Close, open and run the VI.  If this does not help, try the next step.
   4. Close all VIs and LabVIEW itself.  Then open and run all VIs.  It is because some devices are recognized by LabVIEW only when LabVIEW starts.
