Functional Overview

    The PXIe-8301 remote control module is based on Intel Thunderbolt 3 technology. This enables control of a PXI Express chassis from a host PC with an available Thunderbolt 3 port. Thunderbolt technology is transparent to device drivers, so no additional software is needed for CompactPCI Express-level support for PXI Express devices in connected chassis.

    The link between the PC and the chassis is a Thunderbolt 3 link. This link is a dual-simplex communication channel comprised of differentially driven signal pairs. The link can transmit at a rate of up to 40 Gbps in each direction simultaneously.

    The PXIe-8301 supports 2 and 4-link configuration per the chassis' capabilities.

    The PXIe-8301 is compatible with previous generations of PXI Express but requires a Gen 3 PXI Express chassis for maximum performance. National Instruments offers Gen 3 chassis that allow the PXIe-8301 to establish Gen 3 backplane links.
