Controlling PXI and PXIe instrumentation from a rackmount computer needs an MXI-Express host adapter — and a platform with the PCIe slots, lanes and BIOS behavior to run it reliably. The National Instruments host adapters below are verified in DuroPC systems; programs typically pair them with avionics bus and serial cards in the same chassis.
Defense automated-test-stand programs have run MXIe-to-PXIe bridging on DuroPC platforms across multiple hardware generations, alongside MIL-STD-1553 and ARINC 429 interfaces under hard real-time control — see the distributed test-stand case study.
| Manufacturer | Model | Part number | Bus | Verified in |
|---|---|---|---|---|
| National Instruments | PCIe-8381 | — | PCIe x8 | DuroPC systems — configuration verified at order |
| National Instruments | PCIe-8371 | — | PCIe x4 | DuroPC systems — configuration verified at order |
National Instruments PCIe-8381
PCIe x8 host adapter for MXI-Express, linking a DuroPC rackmount to PXIe instrumentation chassis at full Gen 2 x8 bandwidth. Verified in DuroPC systems driving automated test stands.
National Instruments PCIe-8371
PCIe x4 host adapter for MXI-Express, pairing with the PXIe-8370 remote control module for PXI system control. Verified in DuroPC systems.
