Key product information and technical features.
NI PXIE-8384 is an NI PXI Express bus extension module described by NI as a “PXIe, x8, MXI-Express Daisy-Chain Interface, PXI Bus Extension Module.” It is a primary PXI bus extension module rather than a DAQ device or cable accessory. NI states that the module is used to create multichassis PXI systems interfacing to the same computer and supports daisy chaining up to eight PXI chassis on the same system computer.

The module uses a PXI Express bus connection with MXI-Express Gen2 x8 communication and NI lists a theoretical bandwidth of 4 GB/s. NI specifies copper as the supported cable type, and the published specifications list a maximum cable length of 5 m. NI also notes that the supported NI copper cables in the 782317-0x family are passive.

For installation, NI specifies that the PXIe-8384 requires one peripheral slot in a PXI Express or CompactPCI Express system. NI’s compatibility information further states that PXIe-8384 is supported in PXI Express peripheral and hybrid chassis slots, but not in controller slots. NI system documentation identifies the PXIe-8384 as part of the expansion-chassis side of the Gen2 x8 daisy-chain system alongside the PXIe-8381.

Product-specific answers based on available technical information.
NI identifies the PXIe-8384 as a “PXIe, x8, MXI-Express Daisy-Chain Interface, PXI Bus Extension Module,” meaning it is a PXI Express bus extension module rather than a measurement I/O module.
NI states that the PXIe-8384 can daisy chain up to eight PXI chassis to the same system computer.
NI states the PXIe-8384 is compatible with PXI Express peripheral and hybrid chassis slots, but not controller slots.
NI lists the included items as the module and safety/environmental/regulatory documentation only. NI separately lists MXI-Express x8 copper cables as system components, indicating the cable is an accessory rather than the primary module.
