The National Instruments 784177-01, also known as the PXIe-PCIe-8398, is a high-performance host interface card designed to facilitate direct control of PXI Express chassis through a PCI Express Gen 3 x16 link. This card connects desktop or rackmount systems to the PXIe-8398 or PXIe-8399 remote control modules using high-speed Gen 3 x8 copper cables, ensuring efficient communication that is essential for demanding industrial and testing applications. Measuring 6.89 cm by 16.77 cm (2.71 in. by 6.60 in.) and weighing approximately 0.147 kg (0.325 lb), the 784177-01 requires a single PCIe x16 slot in the host PC and supports a maximum cable length of 3 meters.

This interface card is compliant with PCI Express Specification Revision 3.0, ensuring compatibility with contemporary computing platforms. It operates within a wide temperature range of 0 °C to 55 °C and humidity levels of 10% to 90%, non-condensing, making it suitable for various laboratory and industrial environments. The card is built to endure elevations up to 2000 meters and conforms to IEC 60068-2 standards for storage, capable of being stored between -20 °C and 70 °C.

Complying with international standards, including IEC 61010-1 and EN 61010-1, the device meets EMC requirements such as EN 61326-1 and FCC Part 15B for Class A emissions, ensuring minimal interference in controlled laboratory settings. To maintain optimal performance, the 784177-01 should be cleaned with a soft nonmetallic brush and thoroughly dried prior to use. Designed exclusively for indoor applications, this host interface card is a reliable and efficient solution for high-speed remote control in PXI Express systems.
