Configure Page for: Print PDF Rich Text
  • 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
  • Minimal CPU overhead with high-speed DMA interface; 128 B transmit and receive FIFOs
  • Flexible standard and nonstandard baud rates from 57 baud to 1,000,000 baud
  • 10P10C (RJ50) connectors, four 10P10C to DE9M (DB9) cables included


The NI PCI-8432/4 interface offers all of the features of the high-performance NI PCI-843x boards plus high-voltage, port-to-port isolation. The PCI-8432/4 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 baud and 1,000,000 baud 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 PCI-8432/4.

The PCI-8432/4 includes four 10-pin modular jack to 9-pin D-Sub male cables to easily connect to standard serial devices.
