The NI SCXI-2400 Remote Communications Module provides serial communication between a host computer and National Instruments SCXI chassis, enabling remote operation and distributed data acquisition across industrial and laboratory environments. This single-slot SCXI module bridges the host controller and remote equipment through configurable RS-232 or RS-485 serial interfaces, supporting point-to-point and multi-drop network topologies. The module draws power directly from the SCXI chassis backplane and integrates with NI-DAQmx drivers and development platforms including LabVIEW, LabWindows/CVI, and Measurement Studio.
Technical Specifications
• Communication Protocol: Serial (RS-232/RS-485 configurable)
• Data Transfer Rate: Configurable, dependent on serial interface settings and cable length
• Host Interface: SCXI connector for chassis backplane integration
• Remote Interface: DB9 connector (RS-232) or screw terminals (RS-485)
• Power Supply: SCXI chassis backplane
• Form Factor: Single-slot SCXI module
– Key Features
• Dual serial protocol support—RS-232 for point-to-point links and RS-485 for multi-drop configurations with differential signaling
• Low power consumption optimized for SCXI system integration
• Enhanced noise immunity on RS-485 circuits enabling extended cable runs
• Direct chassis integration via SCXI backplane connector eliminates external interfaces
– Typical Applications
• Remote data acquisition from distributed SCXI measurement modules
• Distributed control systems across manufacturing facilities and test laboratories
• Industrial automation with real-time monitoring and command transmission
– Compatibility & Integration
The SCXI-2400 operates in all standard National Instruments SCXI chassis. Software support includes NI-DAQmx drivers and integration with LabVIEW, LabWindows/CVI, and Measurement Studio across compatible Windows operating system versions.
