NI Multisim features more than 450 predefined standard connector symbols and footprints to accurately prototype custom circuitry for different hardware platforms.
More than 180 of these connectors are specific to NI hardware systems. A 68-pin VHDCI connector is used to build custom-load boards for single-ended test and measurement applications based on the NI R-series data acquistion modules. These modules use an FPGA-based system timing controller to make all analog and digital I/O configurable for application-specific operation. The connector comes in both vertical (NI-780389) and right-angled (NI-778914) standards, and is used on all the PXI and PCI R-series modules.
Depending on the module you are using, different DIO, AI, and AO allocations are assigned to the connector pins. Multisim simplifies the schematic capture process of these components on your design with dedicated component sections for each functionality.
