The NI PXI-8431/2 is a high-performance, 2-port serial interface module for high-speed communication with RS485 and RS422 devices at rates of up to 3,000 kbit/s. High-performance RS485 interfaces are available with up to eight ports. The PXI-8431/2 offers flexible baud rates for data transmissions between 57 baud and 3,000,000 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. Using memory mapping, you can connect to more communication points without resource conflicts. National Instruments also offers easy-to-use powerful software that significantly reduces your development time for systems using serial communication with the PXI-8431/2.
