ViStatus niRFSA_resetDevice(ViSession vi);


Performs a hard reset on the device. A hard reset consists of the following actions:

  • Signal acquisition is stopped.
  • All routes are released.
  • External bidirectional terminals are tristated.
  • FPGAs are reset.
  • Hardware is configured to its default state.
  • All session attributes are reset to their default states.

During a device reset, routes of signals between this and other devices are released, regardless of which device created the route. For example, a trigger signal exported to a PXI trigger line that is used by another device is no longer exported.

On the PXI-5600, if you are driving the PXI_CLK10 line, you continue to drive the clock even after a device reset. To stop driving the PXI_CLK10 line, use the niRFSA_ConfigurePXIChassisClk10 function and set the pxiClk10Source parameter to NIRFSA_VAL_NONE_STR or set the NIRFSA_ATTR_PXI_CHASSIS_CLK10_SOURCE attribute to NIRFSA_VAL_NONE_STR.

Supported Devices: PXI-5600, PXIe-5601/5603/5605/5606 (external digitizer mode), PXI-5661, PXIe-5663/5663E/5665/5667/5668, PXIe-5693/5694/5698
