The National Instruments 779723-01, identified as the PCIe-8371 remote controller, is an MXI-Express device engineered for seamless management of PXI Express and CompactPCI Express systems. Utilizing an x4 PCI Express link over copper cabling, this device connects to the PXIe-8370 remote control module, enabling PXI modules to function as if they were directly installed in a standard computer. The transparent nature of this connection ensures that no additional programming is required, and it remains fully compatible with existing drivers and software applications.

When paired with a PXI Express chassis, the 779723-01 supports a sustained throughput of up to 798 MB/s, allowing any desktop or server PC equipped with an x4 or higher PCI Express slot to efficiently control PXI Express and CompactPCI Express systems. This device employs PCI Express-to-PCI Express switches to transmit signals over a cable length of up to seven meters, providing users the flexibility to physically separate their measurement or automation system from the host PC. Furthermore, with a single PCI Express-based computer or PXI Express embedded controller, users can effectively manage multiple PXI Express or CompactPCI Express chassis.

The architecture of the 779723-01 is designed to be transparent to device drivers due to its PCI Express technological foundation, eliminating the necessity for additional software support for CompactPCI Express connectivity. The x4 cabled PCI Express link features four low-voltage, differentially driven signal pairs capable of simultaneous transmission at rates of 10 Gbps in each direction. Compatibility extends to x4, x8, and x16 PCI Express slots, with dimensions measuring 10.7 by 17.5 cm (4.4 by 6.9 in.) and a requirement for a single PCI Express x4 slot. The device is compliant with PCI Express Specification 1.0a, and it operates effectively within an ambient temperature range of 0 to 40 °C.
