  • 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)
  • Compatible with Windows and LabVIEW Real-Time OSs
  • High-speed DMA interface minimizes CPU overhead
  • Flexible standard and nonstandard baud rates from 57 baud to 1,000,000 baud
  • 128 B transmit and receive FIFOs; compatible with Modbus serial


The NI PCI-8432/2 industrial RS232 serial interface offers all of the features of high-performance NI PCI-843x boards plus high-voltage, port-to-port isolation. The PCI-8432/2 features high-speed communication with RS232 devices at rates of up to 1 Mbit/s and offers configurable baud rates for data transmissions between 57 bit/s and 1 Mbit/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. Through the 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 PCI-8432/2.
