National Instruments PCIe-7821R Digital Reconfigurable I/O Device
The NI PCIe-7821R (Part number: 785359-01) Digital Reconfigurable I/O Device can be programmed for RSE or NRSE input modes. Utilize the RSE input mode for gliding signal sources. For this situation, the NI PCIe-7821R gives the reference ground point to the outer signal. Utilize the NRSE input mode for ground-referenced flag sources. For this situation, the outer signal supplies its own specific reference ground point and the PCIe-7821R does not have to supply one.
In single-finished information modes, electrostatic and attractive noise couples into the signal associations more than in differential info modes. The coupling is the aftereffect of contrasts in the signal way. Attractive coupling is relative to the territory between the two signal conductors. Electrical coupling is a component of how much the electric field contrasts between the two conveyors.
The ground purpose of the signal ought to be associated with AISENSE. Any potential distinction between the NI PCIe-7821R ground and the flag ground shows up as a typical mode motion at both the positive and negative contributions of the instrumentation amplifier. The instrumentation enhancer rejects this distinction. If the information hardware of a NI PCIe-7821R is referenced to ground in RSE input mode, this distinction in ground possibilities shows up as a blunder in the deliberate voltage.
The instrumentation amplifier included in this model can dismiss any voltage caused by ground potential contrasts between the signal source and the gadget. With differential info associations, the instrumentation intensifier can dismiss normal mode clamor pickup in the leads interfacing the flag sources to the gadget. The instrumentation amplifier can dismiss basic mode signals when V+in and V– in (input signals) are both inside their predefined input ranges.

National Instruments PCIe-7821R Frequently Asked Questions
Question: How do I set the PCIe-7821R to a different power-on state?
Answer: To set another power-on state, you can configure the PCIe-7821R to load a VI when the system powers on. The VI can then set the DIO lines to any power-on state.
Question: How do I install noise suppression ferrites on the PCIe-7821R?
Answer: To install noise suppression ferrites with the PCIe-7821R, for each connected I/O cable you need to install two snap-on ferrite beads, one on each end of the cable, as close to the connector as practical.
Question: What software do I need to have installed on my computer before installing the PCIe-7821R?
Answer: You should have LabVIEW 2017 or later, LabVIEW FPGA Module 2017 or later and NI R Series Multifunction RIO Device Drivers May 2017 or later before installing the PCIe-7821R.
