About This Manual • DAQ Assistant Help—Contains information about creating and configuring channels, tasks, and scales using the DAQ Assistant. For more information, in Measurement& Automation Explorer (MAX), select Help»Help Topics»NI-DAQmx»DAQ Assistant. • PXI Hardware Specifications Revision 2.1—Introduces the PXI architecture and describes the electrical, mechanical, and software requirements for PXI.
The NI 660x devices contain the National Instruments MITE PCI interface. The MITE offers bus-master operation, PCI burst transfers, and high-speed DMA controller(s) for continuous, scatter-gather DMA without requiring DMA resources from your computer.
Chapter 1 Introduction sub-buses and PXI. The standard implementation for CompactPCI does not include these sub-buses. The PXI TIO Series device works in any CompactPCI chassis adhering to the PICMG 2.0 R3.0 core specification. PXI-specific features are implemented on the J2 connector of the bus. The PXI device is compatible with any chassis with a sub-bus that does not drive the lines used by that device.
Chapter 2 Device Overview Figure 2-1 shows an example of prescaling. External Signal Prescaler Rollover (Used as Source by Counter) Counter Value Figure 2-1. Prescaling Example Prescaling is intended for use with two counter period and frequency measurements where the measurement is made on a continuous, repetitive signal.
Chapter 2 Device Overview Example Application That Works Incorrectly (Duplicate Counting) In Figure 2-5, after the first rising edge of Gate, no Source pulses occur. So the counter does not write the correct data to the buffer. No Source edge, so no value written to buffer.
Chapter 2 Device Overview Transfer Rates The maximum sustainable transfer rate a TIO device can achieve for a buffered acquisition depends on the following factors: • Amount of available bus bandwidth • Processor speed and operating system • Application software To reduce the amount of bus activity, limit the number of devices generating bus cycles.

For information about programming the NI 660x devices at the register level, refer to the NI 660X Register-Level Programmer Manual. The National Instruments Measurement Hardware Driver Development Kit (MHDDK) provides development tools and a register-level programming interface for NI data acquisition hardware. The MHDDK provides access to the full register map of each device and offers examples for completing common measurement and control functions.

Chapter 3 Signal Connections consecutive rising edges of the filter clock. The frequency of the filter clock timebase determines whether a transition in the signal may propagate or not. The function of the internal sampling clock is to increase the sampling rate and prevent aliasing.

Chapter 3 Signal Connections Figure 3-4 shows the timing requirements for the CtrnSource signal. Tsrcper Tsrcpw CtrnSource Tgatepw Figure 3-4. Timing Requirements for CtrnSource Signal Figure 3-4 shows the minimum pulse width and period that you must use for the CtrnSource signal. This signal must satisfy both minimum criteria. If the high phase of the CtrnSource signal is Tsrcpw ns, the low phase must be Tsrcper - Tsrcpw.
Chapter 3 Signal Connections You can export the CtrnGate signal to the I/O connector’s default PFI input for each CtrnGate. For example, you can export the gate signal connected to counter 0 to the PFI 38/CTR 0 GATE pin, even if another PFI is inputting the Ctr0Gate signal.
NI-DAQmx Help, and/or use the examples that are available with NI-DAQmx. Real-Time System Integration Bus TIO devices use the National Instruments Real-Time System Integration (RTSI) bus to easily synchronize several measurement functions to a common trigger or timing event. In a PCI system, the RTSI bus consists of the RTSI bus interface and a ribbon cable.
Do not connect the +5 V power pin directly to D GND, R GND, or any pin configured for output on NI 660x devices, or any voltage source or output pin on another device. Doing so can damage the device and the computer. National Instruments is not liable for damages resulting from such a connection.

Chapter 3 Signal Connections Cable PFI 11 Capacitance PFI 10 PFI 10 PFI 11 Figure 3-10. Crosstalk Example In Figure 3-10, PFI 10 and PFI 11 are configured as inputs. V drives PFI 10 and V drives PFI 11. When PFI 10 (the offending line) transitions from one state to another, it induces a small transition in PFI 11 (the victim line).
