The NI PXI-8174 is an embedded PXI/cPCI controller purpose-built for test and measurement applications in industrial and laboratory environments. Built around a 566 MHz Pentium III processor, it delivers deterministic control and data acquisition orchestration across distributed PXI and CompactPCI chassis architectures. The controller occupies a single 3U PXI system slot and requires three additional controller expansion slots, functioning as the intelligent hub for modular instrument systems.

– Key Features
• Standard VGA video output (15-pin DSUB) for local display and diagnostics
• RS-232 serial communication (9-pin DSUB, COM1) for legacy device integration
• 10/100 Ethernet connectivity for network-based remote access and data streaming
• IEEE 1284 parallel port for external device control and interfacing
• Two USB 2.0 Series A ports (4-pin receptacle type) for peripheral attachment
• PS/2 port for keyboard and mouse input
• Software-controlled trigger routing via front-panel TRG connector to/from PXI backplane trigger distribution bus
• Industrial-grade packaging for harsh operating environments
– Typical Applications
Automated test equipment (ATE) systems, functional and parametric test suites, production line quality assurance, field service instrumentation, and distributed measurement networks requiring centralized control and synchronization across multiple chassis.
– Compatibility & Integration
Fully compatible with PXI-1000B, PXI-1020, and PXI-1025 chassis configurations. The PXI-1020 and PXI-1025 variants support LCD display enable/disable functionality. Windows 2000 and Windows NT environments are supported. Not suitable for real-time deterministic applications requiring LabVIEW Real-Time or LabWindows/CVI Real-Time Module execution.
