This record preserves the supplied VXIPC-873 model identity. The legacy description groups it with VXIpc-871x and VXIpc-872x controllers, but that grouping is not sufficient to establish the hardware configuration of this exact model.
NI publishes documentation for the VXIpc-870 controller family and a controller/driver support matrix. These are useful background references, but neither establishes VXIPC-873-specific specifications or compatibility.
Before purchase or integration, compare the physical unit and its documentation against the model marking, manufacturer label, complete part or assembly number, host-platform compatibility, hardware revision, and required software or driver support. This is especially important for legacy test-and-measurement hardware, where similarly named models can differ by revision, bus type, connector arrangement, supported accessories, or software generation.
This record currently has 2 supporting source references in the SOHO evidence set, including download.ni.com, www.ni.com. Where a specification is not explicitly supported by those sources, it is intentionally left unconfirmed rather than inferred from a related model.
