Information About PXI-8431/8
The PXI-8431/8 is a PXI-based serial interface module developed by National Instruments (NI) for RS485 and RS422 communication. It features eight serial ports configurable for 2- or 4-wire transceiver modes, allowing full or half-duplex data transmission. The module supports data rates up to 3 Mbps and is compatible with Windows-based applications through standard COM port emulation. Designed with a 68-position SCSI interface, the PXI-8431/8 is ideal for distributed automation systems, data acquisition, and industrial serial device integration.
Key Features:
- 8-Port RS485/RS422 Support: Provides eight independent serial ports for high-speed communication.
- Full/Half Duplex Modes: Supports 4-wire full-duplex and 2-wire half-duplex operation.
- High Baud Rate: Operates at up to 3 Mbps, suitable for demanding data transmission needs.
- COM Port Compatibility: Appears as standard COM ports for seamless integration with legacy applications.
- Advanced DMA and Threading: Utilizes high-performance DMA, multithreading, and multiprocessor features.
- Multi-Drop RS485 Networks: Supports up to 32 devices on a single port, ideal for industrial automation.
- PXI Platform Integration: Easily deployable within PXI-based test and control systems.
- Included Accessories: Ships with a 68-pin SCSI to 8 x DB-9 male breakout cable.
The PXI-8431/8 delivers the reliability and scalability required for industrial serial communication and PXI-based system integration.
