The National Instruments part number 784179-01, also known as the PCIe-8398, is a sophisticated device designed for PXI Remote Control applications. As a Gen3 x16 host interface device, it offers data transfer rates of up to 13.6 GB/s through a PCIe x16 Gen3 link, enabling control of compatible PXI and CompactPCI Express chassis. The PCIe-8398 is inserted into an available x16 PCI Express slot on a rackmount or desktop PC and connects seamlessly to a PXIe-8399 or PXIe-8398 remote control module using Gen3 cables, supporting communication distances of up to 3 meters. This controller features integrated temperature monitoring, activating a shutdown protocol with a solid red LED indicator if internal temperatures exceed predetermined limits, ensuring reliable operation. Adhering to the PCI Express Specification, Revision 3.0, the device requires only one PCI Express x16 slot and is capable of supporting an MXI-Express x8 cable. Users can scale their systems by employing multiple NI 784179-01 modules or daisy chaining additional chassis when PCI Express slots are limited. The compact module measures 6.89 cm by 167.65 cm (2.71 in. by 6.60 in.) and weighs approximately 0.147 kg (0.325 lb), making it a versatile choice for expanding automation and measurement systems.
