Instruments»NI-DAQ»NI-DAQmx Help. Accessory Power The NI PXIe-4322 provides auxiliary power for accessories connected to the module and has protection in the event of a fault condition. If a fault occurs in the form of an over-power condition, the power supply latches off until it is reset. To reset after a fault condition perform a Device Reset in MAX or programmatically in your ADE. - Page 23 This category refers to local-level electrical distribution, such as that provided by a standard wall outlet, for example, 115 V for U.S. or 230 V for Europe. Do not connect the NI PXIe-4322 module to signals or use for measurements within Measurement Categories III or IV.

Page 24: Ni Sc Express Considerations
NI SC Express Considerations PXI clock and trigger signals are only available on PXI Express devices. PXI and NI SC Express Clock and Trigger Signals PXIe_CLK100 PXIe_CLK100 is a common low-skew 100 MHz reference clock for synchronization of multiple modules in a PXI Express measurement or control system. The PXIe backplane is responsible for generating PXIe_CLK100 independently to each peripheral slot in a PXI Express chassis. -
