NI PXI-8433/2 (RS485/RS422)

High-Performance, Isolated 2-Port Serial Interface

  • Port-to-port and port-to-PC isolation: 60 VDC continuous (CAT I), 2000 V withstand (Vrms/5 s)
  • 15,000 V ESD protection (human body model)
  • High-speed DMA interface that minimizes CPU overhead
  • Compatible with Windows 7/Vista/XP/2000, LabVIEW Real-Time
  • Flexible standard and nonstandard baud rates from 57 bits/s to 3,000,000 bits/s
  • Memory-mapped to prevent I/O resource conflicts; 128 B transmit and receive FIFOs

The NI PXI-8433/2 serial interface offers all the features of high-performance NI PXI-843x modules plus high-voltage digital, port-to-port isolation. The PXI-8433/2 features high-speed communication with RS485 and RS422 devices at rates of up to 3 Mbits/s and offers configurable baud rates for data transmissions between 57 bits/s and 3 Mbits/s to within 1 percent accuracy for nonstandard baud rates and 0.01 percent accuracy for standard baud rates.

With the high-performance DMA engine, you achieve high throughput with minimal CPU usage. With hyperthreading and multiprocessor capabilities, you can take advantage of the latest PC technology for higher speeds and better efficiency. National Instruments also offers easy-to-use, powerful software that significantly reduces your development time for systems using serial communication with the PXI-8433/2.
