This solution might also apply to other similar products or applications.Select AddRemove Programs or Programs and Features (depending on the Windows OS version).Select the version of NI-DAQmx or Traditional NI-DAQ (Legacy) to remove, and click Remove or Uninstall (depending on the Windows OS version).
To remove NI-DAQ 6.9.3 or earlier, complete the following steps. Select the version of Traditional NI-DAQ (Legacy) to remove, and click Uninstall. With versions earlier than NI-DAQ 6.5, remove the version currently on your computer before installing a newer version. If NI-DAQ 6.8 is installed with LabVIEW 6.0, Traditional NI-DAQ (Legacy) does not appear in the AddRemove Programs view in Control Panel. In this case, you must run the LabVIEW installer to modifyremove Traditional NI-DAQ (Legacy). Ni Daq Plus NI USBAs of release 3.38.1.37437, the entire NI X Series plus NI USB-6000, USB-6001, USB-6002, USB-6003, USB-6008, USB-6009, PCI-6624 and PXI-6624 are supported. RSE and NRSE configured channels use a common ground, while Differential channels use port0 and port8 as and -. Only ports 0-7 and 16-23 can be used simultaneously in a differential or pseudodifferential configuration. If you change the Analog Input port configuration to RSE or NRSE, then the corresponding port (negative port) shows up (offset by 8). Connect the angular encoders channels A, B and, if needed and available, channel Z to the appropriate default NI-DAQmx counter pins. Configure the NI DAQmx Transform output port choosing AngleMeasurement as the Port Sub Type and setting the appropriate values for Position Decoding Method, Enable Channel Z, Z Phase, and Z Value, all of which are meaningful for AngleMeasurement only. Note: Most likely it is possible to also measure linear position with the two-pulse encoder by setting the corresponding NI DAQmx Transform output counter ports Port Sub Type to AngleMeasurement and Position Decoding Method to TwoPulseCounting. Misc: Frequency only applies to the ctr ports and is the base frequency of the PWM Signal for which you are trying to measure the duty cycle. It is the edge of the signal that is used as a reference for the PWM measurement. To set the initial value of the duty cycle, select PropertiesSignal InfoSignal Info Initial Value. These ports map to the DAQs PFI Counter Out ports and pins as shown. The values in Analog Configuration must not exceed the properties of the hardware. The ports input is a number between 0 and 100 corresponding to the duty cycle. If the frequency is known and if measurement is kept exact same as frequency, then there may be issues due to any tolerance issues.
